B1-SWM-Op-Guide-v4.pmd 030108-hto 5 Section One : Introduction SECTION ONE : INTRODUCTION Congratulations on purchasing a Sabine True MobilityTM Wireless System. True MobilityTM Wireless Systems give you all the built-in processing you need on every microphone. 1.1 Using this Operating Guide This operating guide covers all Sabine True MobilityTM Wireless Systems -- model numbers SWM3000 and SWM1600 -- and contains full explanations for everything you need to operate your True MobilityTM Wireless system. Section 2 shows front and back panel views for your True Mobility Wireless receiver. Section 3 lists system components. Section 4 gives the Quick Setup procedures for Receiver & Transmitter Operation and using the FBX Feedback Exterminator®. Note that there is also a quick-start label on top of your True Mobility receiver for the Sabine FBX Feedback Exterminator®, Compressor/Limiter and De-Esser functions. Section 5 details receiver and transmitter installation and setup. Section 6 explains the how and why of Sabine's FBX technology, and gives a complete understanding of how to set up your FBX filters. Section 7 details the True Mobility's De-Esser. Section 8 explains the use of the Compressor. Section 9 gives tips on how to get the best performance from your Sabine Wireless, and describes some possible operating problems and their solutions. Section 10 has frequency charts for all currently available Sabine Wireless systems. Section 11 contains information on how to modify your True Mobility's FBX filters (NOTE: these procedures are to be performed by qualified personnel only), transmitter wiring schematics, and engineering specifications for your Sabine Wireless. Section 12 states caution and warranty information for your True MobilityTM Wireless system. 1.2 System Description Sabine True MobilityTM Wireless Systems come in UHF and VHF models, with many accessories to complete your system packages. Both systems include state-of-the-art Phase Locked Loop (PLL) synthesized transmitter and receivers, True Diversity reception, dual-squelch circuitry, excellent noise rejection and superior dynamic range. Microphone transmitter configurations consist of handheld, lavalier, or headset styles. Sabine True MobilityTM Wireless UHF and VHF systems offer optional front or rear mount antennas, extension antennas, and antenna divider systems. Sabine Wireless Systems are superior to conventional systems because we include the two most comprehensive features found in any wireless system: True Mobility and Targeted Input Processing. We call our system True Mobility because it provides the freedom you should expect from a wireless system. With a conventional wireless system, your range of movement is limited by the potential for feedback in acoustical "hot spots." Some areas are so feedback prone you cannot go near them at all. Other areas allow only minimal gain before feedback occurs. Until now, freedom from mic cables meant more likelihood for feedback. Fortunately, that has changed. Sabine's True Mobility system includes our patented, industry-standard FBX Feedback Exterminator®. Your microphones will sound loud and clear without feedback, and with a greatly increased area of feedback-free movement. This is the freedom you were seeking when you chose a wireless system. Sabine's True Mobility doesn't stop with automatic feedback control. Conventional wireless systems require the added cost of outboard equalizers, compressor/limiters, and de-essers to maximize performance. 6 Section One : Introduction Sabine offers a different approach: on-board processing at no extra cost, all dedicated to one microphone. We call this Targeted Input Processing. With Targeted Input Processing, no mic gets more processing than it needs, and every mic gets precise, targeted control perfectly suited to provide optimal performance. 1.3 System Features All Digital Targeted Input Processing · Patented FBX Feedback Exterminator®: The industry standard in automatic feedback control. The True Mobility FBX function includes our fast Turbo Setup Mode, 10 FBX filters, and easy-to- use controls. · Auto De-Esser: Sabine's new automatic de-essing algorithm senses, tracks, and removes sibilance without affecting the rest of your program. · Compressor: Our famous digital compressor offers the gain management you need to compensate for all types of performers and speakers, from those who are shy around microphones, to the boldest worship leader. You can adjust ratio, threshold and attack settings. True Diversity Receiver · Phase Locked Loop (PLL): Receiver and transmitter are synthesizer controlled via PLL circuitry. · Dual-squelch Circuitry: Sabine 2-stage squelch utilizes Tone Key and Noise squelch systems which eliminate interference and provide quiet, reliable and flexible service. · Dual-NiMH 9-volt Battery Charger: on-board dual-NiMH 9-volt battery charger means you are never out of power for handheld transmitters--saves you hundreds of dollars a year in 9-volt battery costs! Transmitter low-battery warning light lets you know when to change. Sabine's NiMH batteries give you up to 5 hours of battery life and only MINIMAL MEMORY EFFECT! * · Radio Frequency (RF) and Audio signal meters: Bright, easy-to-see-and-read level meters keep you informed of signal strength and audio level. · User-friendly Channel (and Group for UHF) Selection on Transmitters: The RF signal meter helps you find a clear frequency. · Options include: Rear-to-Front Antenna Converter Kit, Antenna Divider Systems, Extension Antennas and Extension Antenna Boosters (Extension Antenna Booster raises the signal +13 dB and requires use of Antenna Divider). * NOTE: MEMORY EFFECT typically occurs when a NiCAD rechargeable battery is recharged before reaching the end of its initial charge. The battery remembers the charge state prior to being recharged and uses that as its "empty" charge state. Sabine NiMH batteries are "memory resistant." You can recharge your batteries any time you please; whether they are 1/2, 3/4 or almost fully charged. You will always get consistent battery life from your Sabine NiMH batteries (for up to 500 charges or more).

B1-SWM-Op-Guide-v4.pmd 030108-hto 9 Section Four: Quick Setup SECTION FOUR : QUICK SETUP 4.1 Receiver & Transmitter Quick Setup Please read Section Five Receiver & Transmitter Setup for a complete understanding of how to set up your True Mobility Receiver. 1. Place the receiver in an open area within visual range of the intended microphone locations. Note that the range of your microphones is about 100 meters, but that structural objects can lessen that range. 2. Turn the Output Level of the receiver and mixer in use to the minimum setting. 3. Connect the unbalanced output (1/4 inch jack) of your True Mobility receiver to the unbalanced input of your mixer or amplifier; or the balanced output (XLR connector) of your receiver to the balanced mic input of your mixer or amplifier. NOTE: when putting the unbalanced output of the receiver into the Line In input jack of a mixer or amplifier, switch the receiver's Level Switch to the High position (see p.10, Fig. 5d). If you connect the unbalanced output of a receiver into the Mic-In input jack of a mixer or amplifier; switch the receiver's Level Switch to the Low position. 4. Turn on Receiver. Set receiver and transmitter to same Group and Channel. Make sure your transmitter is turned off. 5. Check that the RF Signal LEDs are not lighting up. If RF Signal LEDs light up before transmitter is turned on, choose another frequency. 6. Turn on wireless microphone or transmitter. Check that the REF Signal LEDs are lit. 7. Adjust volume. a. Speak into the microphone. Adjust the transmitter Gain until Input Level LEDs (on receiver) light without clipping. NOTE: Step 7.a is for beltpack transmitters only--the Transmitter Gain is not adjustable on handheld microphones. b. Adjust the receiver Output Level to approximately the 12 o'clock position (or loud enough to supply a strong input level to the mixer or amplifier). c. Adjust the volume control of the amplifier and/or mixer to an appropriate sound level. 4.2 FBX Quick Setup Please read Section 6.6 How to Set Up the FBX Section of your True Mobility System for a complete understanding of the FBX function and control. 1. Patch the Sabine receiver into your mixer or amp and position the speakers; then turn on the receiver, transmitter, and microphone. Look for strong RF signal on the front panel meter; check microphone and adjust Output Level for strong input level on the mixer or receiver's amp. 2. Position the microphone in the primary area of use; press and hold the Setup button on the receiver until the Setup indicator flashes 4 times, then release. Do not use microphone for performance in this mode. Do not talk into microphone until setup is complete. 3. Slowly raise the gain on the mixer or amp channel until FBX eliminates the first few feedback tones. Stop raising gain. 4. Move the microphone to another area of use and slowly raise gain until FBX eliminates a few more feedback tones. 5. Repeat step 4 until the Setup indicator automatically goes off and the Ready indicator comes on. You may quit Setup mode at any time prior to its automatic exit by simply pressing the Ready button. NOTE : The Bypass button bypasses only the FBX filters, and not the additional signal processing (de-essing and compression) available in the Targeted Input Processing section of the Sabine True MobilityTM Wireless Receiver. 10 Section Five: Receiver & Transmitter Setup SECTION FIVE : RECEIVER & TRANSMITTER SETUP Each Sabine Wireless System consists of a transmitter and a receiver. Sabine's True Mobility Wireless receivers are True Diversity receivers--that means they have two fully redundant receivers listening for your transmitter and trading off automatically to whichever receives the best signal. 5.1 Multiple Units 5.1.1 Number of Simultaneous Systems UHF receivers/transmitters have 30 frequencies to choose from, but there is a maximum number that can be used in one location (see Section Ten: Multiple Frequency & Use Charts for more information and setup). VHF receivers/transmitters have 16 frequencies to choose from. These also have a maximum number that can be used on one location. UHF and VHF systems can be used together to increase the number of units. Refer to your receiver Frequency Code and the corresponding information in Section Ten: Multiple Frequency & Use Charts for how to set up multiple receivers and transmitters. 5.1.2 Antenna Dividers & Extension Antennas When multiple UHF or VHF systems are in use, a Sabine antenna divider (UHF systems: SWA- 4U; VHF systems: SWA- 4V) can be used to minimize the number of antennas. Extension antennas can be added to maintain good reception even when receivers are far from transmitters. 5.2 Receiver Placement and Connections 5.2.1 Power Cords & Antennas Attach the power cord to the AC Power IN on the back panel and to a 120 - 240-volt AC power source (alternatively, you may use a 12-15 VDC, 0.6A, 10W power adapter as in Figure 5b). Attach antennas or antenna connectors to the antenna A & B TNCs on the True Mobility back panel. 5.2.2. Receiver Placement The receiver should be placed in an open area within visual range of the intended microphone location. Note that the range of your transmitter is about 100 meters, but that structural objects can lessen that range. Extension antennas can be added to maintain good reception even when the receiver is located far from the transmitter. Antenna A AC Power IN Antenna A TNC Receiver-side AC Power cord Figure 5b - DC Power Connections Figure 5a - AC Power and Antenna Connections CAUTION: Do not use third party receivers or transmitters as part of, or in conjunction with your Sabine Wireless system. Some third party microphone and pickups can be configured to work with the Sabine True Mobility. See Appendix 11.2 for wiring diagrams. B1-SWM-Op-Guide-v4.pmd 030108-hto 11 Section Five: Receiver & Transmitter Setup CAUTIONS - Since the installation of the antennas influences the operating efficiency of the receiver, the most important rule is to minimize the distance between receiving antenna and transmitter for better reception and performance. - Keep the system away from electrical-noise sources (electric motors, refrigerators, arc welders, etc.). Place the receiver at least one meter above floor level. Keep all transmitters at least 3 meters away from a receiver antenna. * * See Section Ten for allowable distance between transmitter Figure 5c - Receiver & Antenna Placement and receiver. Your True Mobility receiver can be installed into an EIA standard rack-mount case using the rack-mount brackets provided. A Rear-to-Front Antenna Converter Kit (SWA100) is available to improve reception on rack-mounted receivers. 5.2.3 Audio Output Connection Connect the unbalanced output (1/4 inch jack) of your True Mobility receiver to the unbalanced mic input of your mixer or amplifier; or the balanced output (XLR connector) of your receiver to the balanced mic input of your mixer or amplifier. Level Switch NOTE 1 : The Level Switch affects only the Unbalanced Output on the receiver. In the "Low" position, the output is the same as the Balanced (XLR) output. In the "High" position, the output is 10 dB higher than the XLR output. Unbalanced Output Cord (¼-inch) MIC LEVEL ONLY Balanced Output Cord (XLR) Balanced Output (XLR) Unbalanced Output (¼-inch) Figure 5d - Audio Output Connection (mic level only) NOTE 2 : Guitar Output: Using ¼-inch jack cable, plug one end into the receiver's unbalanced output and the other end to the input of a guitar amplifier. Switch the Level Switch to the High position. Mixer or Amplifier 12 Section Five: Receiver & Transmitter Setup 5.2.4 Beltpack Headset/Lavalier Microphone connection Plug the Headset or Lavalier connector into the 4-pin threaded connector located on top of the UHF of VHF beltpack transmitter. Be careful to align the notch on the inside of the cord connector with the slot on the inside of the beltpack connector. Low Battery Indicator 1. Hold cord-side of the connector here with index finger and thumb, and place on top of beltpack receptacles. Power Switch 2. While gently pushing to connect, rotate entire connector until notches & slots align, and connector slides into place. 3. Lock in place with screw-on sleeve. Tighten finger-tight. Screw-on Sleeve Figure 5f - Connector Placement Slot Mini XLR Connector NOTE: See Section 11.2 Beltpack Transmitter Connector Wiring Diagrams for Sabine True Mobility connector wiring information. 5.3 Transmitter & Receiver Operating Procedures 5.3.1. Start-up Procedures 1. Power up the True Mobility receiver. The red LED on the power switch will indicate power is on. 2. Check RF Signal indicator LEDs. Other signal sources, including other wireless communication devices and transmitters, can interfere with the operation of your receiver. BePower On fore turning on your microRF Signal LEDs Audio Input LEDs Indicator light phone or beltpack transmitter, check to see if any of the RF Figure 5g - Receiver Controls & LEDs Signal LEDs on the receiver are lit. The number of LEDs that light up will indicate the strength of the interference. NOTE: Some interference can be dealt with using Sabine's two-stage squelch. Adjust the Squelch control knob ("SQ" on rear panel of unit) clockwise until all RF Signal LEDs go out. CAUTION: Increasing the squelch threshold will shorten the operating distance possible between microphone and receiver. A much better solution is to use the Group and Channel selectors to locate a frequency without interference or with minimal interference. 3. Power up your mixer and or amplifier. Turn volume controls to the minimum setting. MIC LEVEL ONLY Squelch Figure 5h - Receiver Back Panel Squelch Control B1-SWM-Op-Guide-v4.pmd 030108-hto 13 Section Five: Receiver & Transmitter Setup 4. Turn on your Sabine Wireless microphone or beltpack transmitter. Select the same Group/Channel as the receiver (see Section 5.4 Group & Channel Selection). Under normal circumstances, the RF Signal indicator on the receiver will light up when a transmitter is turned on within operating range of that receiver. NOTE: The Sabine Wireless receiver has a two-stage squelch system that allows you to turn on or off your transmitter while the receiver and sound system are on--without causing pops or clicks from the Sabine Wireless system. 5. Speak into the microphone. When audio program is added to that RF signal, the Input Level indicators will light up in accordance with the strength of the audio signal. Adjust transmitter Gain to maximum signal without clipping (NOTE: Handheld microphones do not have gain control). 6. Adjust mixer and amplifier levels. 5.3.2. Transmitter LED Indicators Sabine True Mobility transmitters incorporate multifunction LED indicators. These LEDs signify a variety of information depending on when and for how long they are lit. The handheld microphone has an LED next to the Power Switch (Figure 5i), and one inside the Group/ Channel Selector compartment (Figure 5k). The Beltpack Transmitter has both LEDs together on the front control panel. Power/Battery LED Figure 5i - Handheld Microphone Power/Battery LED 5.3.2.1 Power/Battery LED. The Power/Battery LED comes on when you first insert the battery (Handheld Microphone only), and when you first turn the microphone/transmitter on. It stays on for about two seconds and signifies that the microphone/transmitter is in mute mode during that time. The LED will then go off automatically, signiUnused Group/Channel LED fying that the microphone/transmitter is now in active mode. If, after turning on the microphone/transmitter, the LED comes on and stays on, this signifies that the battery is weak and should be replaced with a Sabine rechargeable battery from inside the built-in battery comFigure 5k - Handheld Microphone Channel LED partment. 5.3.2.2 Unused Group/Channel LED. This LED comes on for about two seconds whenever you change a Group/ Channel setting. If the LED stays on, then the setting you have selected is not available, and you need to select another. Please refer to the Group/Channel chart for your system in Section Ten. Group Selector* Channel Selector Indicates unused frequency Gain Guitar/Mic Switch *NOTE: SWM1600 VHF microphones and transmitters do not have a Group selector. Figure 5j - Beltpack Transmitter LEDs 14 Section Five: Receiver & Transmitter Setup 5.4 Group & Channel Selection Sabine True Mobility UHF Wireless transmitters are preprogrammed with 30 switchable combinations of Groups/Channels; True Mobility VHF Wireless transmitters are preprogrammed with 16 switchable Channels. Both systems allow easy change of transmitter settings. Group & Channel Selectors RF Signal LEDs Input Level LEDs Output Level Control Change Group/Channel when: - RF Signal indicator lights flash when you do not have a microphone or transmitter turned on. - You have several True Mobility Wireless systems operating at once. Each system must operate at a unique Group and/or Channel setting (see Section Ten). 5.4.1 Selecting Transmitter/Receiver Groups/Channels 1. Turn on the True Mobility receiver -- leave transmitter in off position. 2. Check for RF interference. If the RF Signal LEDs are lighting up, set Group and/or Channel selectors to a different setting. Repeat this until a clear channel is located (no RF signal). 3. Using your fingernail or small screwdriver, carefully set the Group and/or Channel knobs on the transmitter to the same setting as the receiver (handheld microphone Group and Channel selectors are located inside the sliding-door compartment above the antenna). Figure 5l - Receiver Group/Channel Sliding Door To open: press down firmly on ridged area with thumb and slide toward antenna. Group Selector Channel Selector Figure 5m - Handheld Group/Channel Selectors NOTE: SWM1600 VHF systems do not have a Group selector 4. Turn on the transmitter and check to see if the RF Signal LEDs light up. 5.4.2 Group/Channel Selection (Multiple Receivers/Transmitters) SWM3000 UHF transmitters and receivers have both Group and Channel selector knobs. The channels within each group have been arranged so that you can use multiple wireless units at a single location, without having the units interfere with each other. Refer to Section Ten Multiple Use & FreGroup Selector* quency Charts for how to use multiple Channel Selector True Mobility Wireless Systems toIndicates unused frequency gether. Gain NOTE : If you are using only one Sabine True Mobility Wireless transmitter/receiver, simply select a group/channel that does not indicate interference. See Section 5.3, #2 to determine if there is RF interference present at your location. Guitar/Mic Switch *NOTE: SWM1600 VHF microphones and transmitters do not have a Group selector. Figure 5n - Beltpack Group/Channel Selectors B1-SWM-Op-Guide-v4.pmd 030108-hto 15 Section Five : Receiver & Transmitter Setup 5.5 Audio Output Settings 5.5.1 Unbalanced Audio Output Follow these steps to adjust Unbalanced Audio Output from your True Mobility receiver (refer to Section 5.2.3. Audio Output Connection for information on balanced/unbalanced audio connection). 1. Switch the Level Switch on the reOutput Level ceiver rear panel to the "Low" position Figure 5o - Audio Output If you are plugging into a microphone input on a mixer or amplifier. See Note 1 on page 12 for Level Switch information. 2. Adjust the receiver Output Level knob to the 12 o'clock position (straight up). 3. Adjust the volume control of the amplifier or mixer to an appropriate sound level. NOTE : The Output Level control on the receiver is used for fine tuning the wireless microphone output. At the 12 o'clock position, the output level of the wireless microphone is the same as that of most standard dynamic microphones. 5.5.2 Balanced Audio Output 1. Adjust the receiver Output Level knob to the 12 o'clock position (straight up). 2. Adjust the volume control of the amplifier or mixer to an appropriate sound level. NOTE: Balanced Output is not affected by the Level Switch setting CAUTION: If the receiver Output Level is set too high, it will cause your sound to be distorted. Conversely, signal to noise ratio (S/N) will worsen if the receiver Output Level is adjusted too low. For more information on getting the most out of your True Mobility system, refer to Section Nine Tips & Troubleshooting 5.6 Transmitter Battery Installation 5.6.1 Battery Usage Sabine True Mobility Wireless handheld microphones and UHF/VHF beltpack transmitters are designed to use common 9-volt transistor batteries. An alkaline 9-volt battery (IEC 6LR61, or equivalent ANSI and NEDA 1604A) will typically provide 8 hours or more of operation. Your True Mobility Wireless System comes with a Sabine rechargeable 9-volt size) Nickel Metal Hydride (NiMH) battery. This battery can be recharged using the built-in battery charger on your receiver. With a full charge, the typical life of a rechargeable battery is approximately 3 hours or more. NOTE: Make sure to turn off the microphone/transmitter after use to extend the battery life. Remove the battery from the battery compartment if the microphone or transmitter will not be used for an extended period of time. Rechargeable batteries can be stored in the built-in battery charger on the receiver, however, the overall battery life (number of times the battery can be recharged) will be reduced somewhat. CAUTION DO NOT BURN OR PUNCTURE BATTERY. DOING SO COULD RELEASE TOXIC MATERIALS WHICH COULD CAUSE INJURY.

Feedback is certainly the most embarrassing, most pervasive challenge to the audio industry. The potential appearance of sudden, loud, out-of-control feedback is every sound engineer's and musician's nightmare. It disturbs the performer, the audience, and the technician; and can damage equipment and just generally ruin your day. A typical wireless microphone adds a new level of unpredictability to feedback potential. Feedback involves a relationship between a speaker and a microphone, and the physical distance between the two is the principal determinant of feedback. A mic that can move anywhere results in an ever changing potential for feedback. A step in the wrong direction may change a clear, loud sound to a piercing shriek in less than a second. The potential for feedback with a wireless system is increased further if lavalier microphones are used. Lavalier microphones are placed farther from the mouth than handheld or head set microphones, and often require more gain. Lavalier microphones are also frequently omnidirectional, meaning they pick up sound equally from all directions, increasing the chance of feedback due to increased sensitivity to the sound emanating from the speakers. The Sabine True MobilityTM solves this problem by attenuating very narrow bands of feedbackprone frequencies. The process is automatic, simple to use, adaptable to changing acoustical conditions and relationships, powerful in its application, and has minimal consequences to the audio fidelity of the signal. We call this automatic filter an FBX Feedback Exterminator® filter, or FBX filter for short. Before the invention of FBX, the most common device for controlling feedback was the 31-band graphic EQ. However, FBX has three distinct advantages. The most obvious is that FBX functions automatically, even during the program. Another is that FBX micro-filters are precisely placed anywhere feedback occurs, while EQ filters are limited to 31 fixed centerpoints. The difference: FBX filters do not have to be as deep, so there is more system gain. But the most important advantage is that FBX micro-filters are ten times narrower than 31-band EQ filters. Using FBX micro-filters will return up to 90 percent of the power removed by EQ filters. An EQ would need more than 10,000 sliders to be equivalent to your FBX. With FBX technology, your microphone will finally sound loud enough, everyone in the audience will understand each word, and feedback will be far less likely to make an unwelcome and unexpected visit. -10 dB cut at 500, 630, 1K, 1.25K, 1.6K &2K Hz If the graphic EQ really had 1/3 octave filter widths, the frequency response curve would vary 6 dB between sliders. This would ruin the sound. Graphic EQs usually use one-octavewide overlapping filters that provide much smoother frequency response curves. Notice that the overlapping filters add together to cut -16 dB when the sliders are only pulled down -10 dB. Figure 6a - Graphic-EQ effect on program B1-SWM-Op-Guide-v4.pmd 030108-hto 19 Section SIX : FBX Feedback Exterminator 6.2 Two FBX Advantages There are two reasons why the True MobilityTM system from Sabine is able to eliminate feedback while maintaining a high quality audio signal. Direct Hit on Feedback! FBX filter You get back this much sound & power with the FBX! Feedback 6.2.1 Advantage #1 The grey area shows you how First, an FBX filter represents a direct hit much of your on feedback! The FBX targets feedback 1/3-octave program you without taking a big chunk out of your sound. EQ filter would lose using a Tests prove that a single 1/3-octave EQ 1/3-octave filter to control feedback slider pulled down 12 dB removes almost half the power going to the speakers over a two-octave range. Furthermore, you can't place a graphic EQ filter precisely on the Figure 6b - FBX Filters a Direct Hit on Feedback ringing frequency. If you pull down multiple sliders in a normal setup, you end up with giant frequency holes in your music (see Figure 6b). On the other hand, FBX micro-filters are 10 times narrower--you get back up to 90% of the power you lose with a graphic EQ! That means more gain before feedback and no loss in sound quality. EXAMPLE: In Figure 6c, a PA system was set up using a microphone, mixer, FBX Feedback Exterminator®, power amp and two speakers. The system's gain was raised until the FBX removed nine feedback points. Next, the FBX was replaced with a graphic EQ. The EQ was adjusted while the system gain was raised to the same level achieved with the FBX. The frequency response curves of each device were then plotted. Figure 6c - FBX Filters vs Graphic EQ Filters Note how much more of the program is eliminated using an EQ--whereas only feedback is eliminated using FBX filters. 6.2.2. Advantage #2 The second reason True MobilityTM systems are able to remove feedback while maintaining high quality audio signal is due to the placement of the signal processing in the input chain of the microphone signal. Many times signal processing (compression and equalization) is placed after the output stage of a mixer, meaning it is applied to a combination of inputs mixed together into one output and passed through the processor. Particularly in the case of equalization and feedback control, one consequence of such a signal path is that filtering applicable to just one microphone is applied to others in the same mix bus. In other words, unnecessary filtering (albeit very narrow filtering in the case of an FBX filter) may be applied to microphones that have different feedback frequencies than some of the filters set. Placing the filtering and other signal processing in the input signal path is a concept called Targeted Input Processing. It means each microphone so equipped will have customized, unique signal processing applied--and no unneeded processing. Sabine True Mobility Wireless Systems give you - Targeted processing for each microphone - Increased mobility - Quiet, fast and easy setup of FBX filters (Our Fastest FBX setup mode!) 20 Section Six : FBX Feedback Exterminator Constant Q vs Proportional Q Filters Constant Q Proportional Q It is common to describe a filter's quality factor, or "Q," as the center frequency of the filter divided by the filter width (in Hertz) measured at the -3dB point. Filters that have the same Q, or width, at the -3dB point regardless of the filter's cut or boost are called Constant Q filters (see p.14, Figure 6a). Filters that get wider as the filter gets deeper are called Proportional Q filters (see p.14, Figure 6b). Lately, however, the definition of Constant Q is becoming less distinct. Many equalizer manufacturers claim their equalizers have Constant Q filters, when in fact they get substantially wider as they get deeper. The only way to know for sure if the filters are truly Constant Q is to inspect their frequency response curves. Sabine FBX Filters are true Constant Q filters. 6.3 Who Needs The FBX? Virtually every sound system will be improved with the Sabine True MobilityTM Wireless System. Singers and speakers who do not have sound technicians can now increase their monitor or house system volume so they can hear themselves clearly and with full fidelity, without worrying if their microphone will suddenly squeal if they move to the wrong place. Auditoriums and churches of all sizes will enjoy reliable feedback control. Hotels and conference centers around the world can offer meeting rooms with microphones that won't howl during programs. The Sabine True MobilityTM Wireless System can be installed in theaters, schools, sports arenas, courtrooms, teleconferencing, intercoms or interactive remote classrooms--anywhere one or multiple microphones are used. 6.4 FBX Setup & Ready Mode The FBX Section has two modes: Setup and Ready. In Setup, the FBX filters automatically zero in on the most predominant feedback. Because this is a wireless system, you need to move the microphone to several areas of use during setup--this will provide maximum gain before feedback before the performance begins. In Ready mode you are ready for the performance. Use the True Mobility as you would any wireless microphone system. The FBX section will work automatically to kill any additional feedback that happens to arise. 6.4.1 FBX Fixed & Dynamic filters Here's how it's done. FBX filters come in two flavors, fixed and dynamic. Both operate automatically. Fixed FBX filters: these filters will not change frequency or depth once they are placed during Setup and the receiver indicates Ready mode. These filters will eliminate the "first-to-feedback" frequencies encountered during normal system operation. Dynamic FBX filters: these filters automatically set just like Fixed filters, except they can change frequency and depth as the need arises. Dynamic Filters stand guard if frequencies not attenuated during Setup begin to feedback during performance. If all filters, both Dynamic and Fixed, are in place and new feedback occurs, the Dynamic filters will move to eliminate the new feedback. You never run out of filters! B1-SWM-Op-Guide-v4.pmd 030108-hto 21 Section Six : FBX Feedback Exterminator 6.4.2 Default FBX filter settings The Sabine True MobilityTM Wireless System provides a total of ten filters for feedback control. The default setting makes seven of these Fixed and three Dynamic. This can be changed to eight Fixed and two Dynamic by changing an internal DIP switch position (see Appendix 11.1 FBX Configuration DIP Switch). 6.4.3 FBX filter width A default setting of .10 octave has been calculated to eliminate feedback without affecting music program. If, with all filters properly set, feedback is still occurs, the FBX filters may be set to .20-octave width. This wider filter setting will help to eliminate feedback trouble areas, but may also affect music program slightly. The wider setting is generally considered to be appropriate where speech is the primary usage of the Sabine Wireless. This is to say it will not audibly affect desired program, only feedback. If the Sabine Wireless is used for music program, we recommend using the default setting of .10 octave be used. You can change FBX filter width by repositioning an internal DIP switch (see Appendix 11.1 FBX Configuration DIP Switch). 6.5 How To Set Up The FBX Section Of Your True MobilityTM System Follow these steps to obtain the maximum gain and protection from feedback. 1. Place the speakers in the positions where they will be used during the program. 2. If there is any equipment with a noise gate in the signal path, you MUST DISENGAGE the noise gate(s) prior to the setup procedure. You may reengage these noise gates upon conclusion of your FBX setup. 3. Patch your Sabine receiver into the mixer or amp channel. Set the amp master output gain to a normal operating position. NOTE: The level of your power amplifier should be set to a level that allows a healthy gain structure prior to the amplifier. If your amplifier is turned up fully, and your mixer meters show little movement when signal passes through, you will improve the performance of your sound system and lower system noise by reducing the gain on your power amp and increasing your mixer gain. 4. Turn on your wireless transmitter or handheld microphone, then the wireless receiver, then the mixer, then any other accessories, and finally the power amp. If you are using a graphic EQ, adjust only for the desired tonal qualities, but DO NOT NOTCH FOR FEEDBACK. Output Level Figure 6d - Receiver Output Level Setup Button Figure 6e - FBX Setup Button CAUTION: Do not use Sabine wireless receiver for performance while in Setup mode! 22 Section Six : FBX Feedback Exterminator 5. Now you are ready to set FBX filters. Press and hold Setup (far left button) on the wireless receiver, until the LEDs flash four times, then release it (the Setup LED will come on). This will clear any FBX filters already in place. You should do this each time you move your sound system, change a sound system component, or relocate your microphone. Your Sabine True MobilityTM Wireless System will remember its settings from the last time you turned the unit off. 6. When the Setup light comes on, your receiver is ready to set FBX filters. With the microphone turned on, raise the Output Level of the receiver slowly until a strong input signal at the mixer is apparent (for starters, try the 12:00 position). The microphone should now be audible. 7. During Setup mode, do not talk into the microphone or pass audio program through a transmitter. This may cause the Sabine True MobilityTM system to set inappropriate filters. The only appropriate use of the setup mode is to create and filter feedback. 8. Slowly raise the mixer channel gain to the point of feedback--and then slowly beyond until you hear the chirping tones of feedback quickly being eliminated by FBX filters setting. Stop raising gain after 2 or 3 feedback tones have chirped and corresponding FBX filters have set. Rest assured that any feedback that occurs will be at a quiet volume, and very short in duration. You may quit Setup mode at any time prior to its automatic exit by simply pressing the Ready button. This will lock all fixed FBX filters, including those not set at the time of your manual exit--in other words, only the filters set at the time you pushed Ready will be engaged. Dynamic FBX filters will still work in the event of feedback during performance. If you quit Setup prior to the FBX Section's automatic exit (i.e.., after all fixed FBX filters are set), and later decide you need more gain before feedback (i.e., more fixed filters), you must begin the Setup process again. See Step 5 above. 9. Move the microphone to another area of use and slowly raise gain until FBX eliminates a few more feedback tones (2 or 3). Repeat this step until the Setup indicator automatically goes off and the Ready indicator comes on. Any feedback that occurs after setup will be eliminated by Dynamic filters. In most instances you will experience an additional gain of 6-9 dB before feedback when using the Sabine True MobilityTM System. Precise results will depend on system and acoustical considerations. Bypass Button Figure 6f - FBX Section Bypass Button All fixed filters in place will remain set until the Setup button is pushed and held as described in step 5. All dynamic filters will remain in place until new feedback occurs (wherein they will move to the new frequency), or until the Setup button is pushed and held. 6.6 Bypass Button The Bypass button bypasses only the FBX Section, and not the additional signal processing (deessing and compression) available in the Targeted Input Processing section of the Sabine True MobilityTM Wireless Receiver. B1-SWM-Op-Guide-v4.pmd 030108-hto 23 Section Seven : De-Esser Set Up SECTION SEVEN : DE-ESSER SET UP 7.1 The Essence of De-essing Certain consonant sounds produced by the human voice have the potential to overload a microphone capsule, and to end up as disproportionately harsh and loud when amplified through a sound De-esser Control Knob system, and/or recorded to analog or digital storage media. The most com- Figure 7a - De-esser Control Knob mon and obvious of these sounds is the "ssss" sound, associated with pronunciation of both "s" and soft "c" consonants in many languages, and also the consonants "t," "f," and sometimes "d." The technical term for this particular vocal sound is "sibilance," and the devices which control such sounds are typically called "de-essers" (or sometimes sibilance controllers). The frequency range of sibilance will vary depending on the singer/speaker, the consonant involved, the orientation to the microphone, the microphone itself, and the normal variations in human vocalization. The range of frequencies affected by sibilance starts above 2.5 KHz, and generally tapers off above 10 KHz. 7.1.1 The True Mobility De-esser The Sabine De-Esser is a type of compressor that operates at frequencies between 2.5 KHz and 12 KHz. The De-Esser reduces the amplitude of vocal sibilant sounds which may become apparent when a singer or speaker gets too close to the microphone. When the energy level of high-frequency sounds exceeds a preset threshold, the de-esser reduces the high frequency response for the length of time the threshold is exceeded. High frequency energy below the threshold will not be affected by the de-esser. Low energy level, high frequency sounds also are not affected. 7.2 Using the De-esser The Sabine De-Esser is simple to use. The fully counterclockwise position is OFF. From that point, the more you turn the knob clockwise, the more sibilance is reduced from your program. Sabine De-Esser can be used to compensate for varying sibilance levels due to placement of lavalier microphones (the closer the lavalier microphone is to the user's mouth, the greater is the potential for audible sibilance). 24 Section Eight : Compressor Set Up SECTION EIGHT : COMPRESSOR SET UP 8.1 Basics of Compression The dynamic range (how loud we can hear to how quiet a sound we can detect) of the human ear is far greater than the capacity of sound systems to reproduce. Although some of this equipment limitation is at the upper extreme of the dynamic range (where too loud a signal will produce distortion), much of the restriction occurs at the low level end, where the signal disappears below the "noise floor" of the circuitry. A compressor (or in its most powerful form, a limiter) is the most widely used tool for controlling dynamic range. In the simplest terms, a compressor is designed to squeeze the dynamic range of an audio program; i.e., to make quiet signals louder, and loud signals quieter. A compressor becomes a limiter when the compression ratio (the ratio of the input gain change to the output gain change) is so high that the output level won't rise above a "brick wall" ceiling regardless of how loud the input gets (typically 10:1 and greater). A compressor acts like an "automatic mix engineer" with a hand on the fader and an inhumanly fast reaction time. When the input level increases, the engineer drops the fader; when the level decreases, the fader is raised. When the amount of fader compensation equals the variation in signal level, the output level of the audio program will sound consistent. The practical benefits of compression and limiting include: 1. Speaker protection. A compressor will control sudden level peaks and prevent your speakers from damage. 2. Perceived increase in loudness. Because peak levels are kept from rising as high as uncompressed signals, you gain headroom for your audio program and can raise its overall average gain. Compression is often added to the entire audio mix, both in live sound and recording, to increase its perceived loudness. 3. Consistent Level. For expressive instruments or vocals, which may have a large dynamic range, compression can help maintain consistent mix levels. So a speaker who varies from a whisper to a shout will not disappear or stand out in the mix, relative to other less dynamic instruments. 8.2 Using the Compressor Compressor controls are located immediately to the right of the FBX and De-esser panels. The controls consist of standard Ratio, Thresh (threshold), and Attack knobs, and a horizontal LED ladder showing compressor gain reduction. Ratio Control Knob Threshold Control Knob Attack Control Knob Ratio: Compression ratio is the ratio of Figure 8a - Compressor Section the input gain change to the output gain change. The compression ratio on your Sabine Wireless ranges from 1:1 to infinity:1 (limiting). Compression threshold is the level at which the compressor/limiter begins to act on the signal. The input level threshold at which compression is engaged can be adjusted from -30 dBV to 0 dBV. Compressor attack time is the time it takes to compress after a strong signal reaches the threshold level. Thresh: Attack: NOTE 1 : Use the mixer channel or amp gain for gain make-up after compression. NOTE 2 : Default Release Time for the True Mobility Compressor is 400 mSec with the Knee set to Soft. B2-SWM-Op-Guide-v4.pmd 030108-hto 25 Section Eight : Compressor Set Up 8.3 Suggested Compressor Settings 8.3.1 Vocal Compression The renowned expressiveness of the human voice is due in large part to its dynamics. A vocal that varies from a whisper to a scream has a strong emotional impact, but those same dynamics present a challenge to the sound engineer. Ideal vocal compression maintains some dynamic range while keeping the vocal the focal point of the mix. Ratio: A soft voice might require a ratio of 2:1, whereas a loud voice might require a ratio setting of 6:1. Thresh: The higher the threshold setting, the more signal required to initiate compression. Attack: Short attack. 8.3.2 Guitar Compression A high compression (with gain makeup) will add sustain to held notes and chords. Moving the threshold will change the audible thick/thinness of the guitar tone, but generally you want to compress all the notes played. Be wary of too quick an attack, which may reduce the percussive attack of the guitar notes. In general, use a longer attack for instruments. Be wary of too high a compression ratio, which may make a noisy guitar amplifier more objectionable. Figure 8b (Ratio set to from 2 to 6:1; threshold set so vocal peaks are compressed about 4-6 dB, attack should be fairly quick). Figure 8c (Ratio set from 6 to 20:1, threshold variable, slower attack.) 8.3.2 Additional Settings For your own recall, draw in any settings and their use that you have discovered. 26 Section Nine : Compressor Setup 8.4 Possible Compression Trouble Areas Like any signal processing, compression can be misused, and cause undesirable problems in the audio signal. Some of these problems include: 1. Noise. If the threshold for compression is set too low, and the output gain is raised substantially to make up for the gain loss of compression, the resulting output signal can be noisy. This is because the input signal must be raised significantly to produce the same output level, and the noise floor of your equipment will be amplified unnecessarily. This problem will be exaggerated if the input signal level to the compressor is very low (which will already degrade the signal-to-noise ratio). 2. Breathing. In situations where the compression ratio is high, the threshold is low, and the release time of the compressor is short, the noise floor will modulate up and down as the audio signal stops and starts. 3. Over-compression. Applying too much compression to a mix can sometimes result in such evened-out dynamics that the "life" of the music has been removed or curtailed. Dynamic variation in music is a major component of its excitement and interest; don't remove them, just control them. This may be particularly true for percussive sounds such as drums. B2-SWM-Op-Guide-v4.pmd 030108-hto 27 Section Nine : Tips and Troubleshooting SECTION NINE : TIPS AND TROUBLESHOOTING 9.1 Tips for Maximum Performance of your True Mobility Wireless System · Keep a clear and unobstructed path between transmitter and receiver. · Position receiver antennas at least one meter off the performance floor level. · Avoid placing receiver antennas near large metallic or other dense materials. · Keep receiver antennas away from RF signal generating equipment (computers, high-voltage equipment, etc.). · If the receiver is rack mounted, you can use the Sabine SWA100 Rear to Front Antenna Converter Kit or one of the Extension Antenna kits ( UHF systems: SWAUEXT; VHF systems: SWAVEXT) to improve RF performance. · Position antennas perpendicular to each other. · Use a Sabine Antenna Divider System (SWA4U, SWA4V) for multiple system installation. NOTE: It is highly recommended that SWAUB Antenna Boosters be used with the Antenna Divider System. The Antenna Boosters will boost the signal +13dB. Placement of the Divider more than 10 meters from the receiver positively requires the use of Antenna Boosters. · Keep two extra Sabine Rechargeable 9-volt NiMH batteries charging in the on-board, dual battery charger. 9.2 Troubleshooting Problem: True Mobility receiver and transmitter power are on, receiver RF Signal LEDs and Input Level LEDs are lighting up, but no sound from system. Solution: Check connection between receiver and mixer/amp. Adjust receiver Output Level control. Problem: True Mobility receiver and transmitter power are on, but receiver RF Signal LEDs and Input Level LEDs are not lighting up. Solution: Check transmitter On/Battery Indicator. Replace weak battery with fresh battery from charger unit if necessary. Check transmitter and receiver frequency Group/ Channel settings (make sure they match). Check receiver squelch setting. Check receiver antenna connections. Check distance between transmitter and receiver antennas and possible obstructions in path. Problem: Transmitter is on, but sound is noisy. Solution: Check transmitter On/Battery Indicator. Replace weak battery with fresh battery from charger unit if necessary. Check for other sources of RF interference (high voltage equipment, lighting equipment, etc.). If using multiple units, make sure that all units are set to different frequencies within their allotted group. Do not mix groups unless so stated in Section Ten. Check distance between transmitters and receiver antennas. Problem: Transmitter is off, but noise still coming from receiver. Solution: Adjust receiver squelch control. Check for other sources of RF interference (high voltage equipment, lighting equipment, trolley cars, etc.). Select another frequency. Check connection and position of the receiver antennas. Utilize a Sabine Extension Antenna and/or Extension Antenna Booster (Extension Antenna Booster requires the use of a Sabine Antenna Divider). 28 SECTION TEN : Multiple Frequency & Use Charts SECTION TEN : MULTIPLE FREQUENCY & USE CHARTS 10.1 UHF Frequency Code U3 [USA] SWM-3000 UHF transmitters and receivers have both Group and Channel selector knobs.

In general, use channels from within the same group to avoid interference. For maximum number of units, see Example #2 on page 29. 30 Section Ten : Multiple Frequency & Use Charts EXAMPLE 1: The 8 channels within group 1 are all compatible with each other. To use 8 UHF units at a single location, set the receivers and transmitters as follows: Transmitter/Receiver unit #1 unit #2 unit #3 unit #4 unit #5 unit #6 unit #7 unit #8 GROUP 1 1 1 1 1 1 1 1 CHANNEL 1 2 3 4 5 6 7 8 EXAMPLE 2: To use the maximum number of 14 units together, use all 7 channels of Group 3, plus all 7 channels of Group 4. NOTE : To avoid intermodulation distortion (IMD) interference, all transmitters must be kept at least 5 meters from any True Mobility UHF receiver antenna.

UNPLUG receiver BEFORE taking off top cover! Serious injury or death may result if unit is opened/worked on while plugged in. These procedures are to be performed by qualified personnel only. Refer to Section 6.5 How to Set Up the FBX Section of Your True Mobility System for a description of Fixed versus Dynamic FBX Filters. Front of box 1. Remove receiver top cover Take out four screws on each side and two from the top of the back panel. Sort and save all screws. Lift the back of the top cover, and then pull until the edge of the top cover (and three tabs) emerge from under the front panel plastic rim. DIP Switch Figure 11a - FBX Configuration DIP Switch 2. Change DIP switch settings There are two PC boards inside the receiver. With the front of the unit facing you, the left and smaller board (Figure 11a) has a DIP switch in the middle of the right hand side. The DIP switch is covered with a translucent piece of yellow plastic wrap. Pull off the wrap (it cannot be reused). Note that there are five switches. One side of the DIP switch is clearly marked ON. The factory default setting is with all switches set to ON (see Figure 11b). Refer to Figure 11c to set the number of Fixed and Dynamic filters to 8 Fixed and 2 Dynamic and Figure 11d to widen the filter width to .20 (1/5) octave. These options can be combined to produce 8 Fixed and 2 Dynamic 1/5-octave filters by pushing switch numbers 1 and 2 to the OFF position (Figure 11e). Refer to Section 6.5 for a complete understanding of these options. 3. Replace top cover Align and insert the three front tabs under the front panel plastic rim, then lower the back of the cover. Replace all screws. DO NOT FORCE screws. If they do not go in easily, adjust cover alignment and try again.

All systems and components conform to the directives outlined in RTTE Directive 1999/5/EC, and to standards ETS 300 445, ETS 300 422, EN 50081-1, and EN 50082-1, as applicable. 2. As of April 8, 2000, these products have been or will be placed on the market in the following European countries: Germany, Norway, Spain, Italy, Switzerland, Belgium, Czech Republic, Russia, Greece, Denmark, and Iceland. 3. All Sabine True MobilityTM equipment bears the CE mark. In addition to Sabine's manufacturer's statement of conformity, compliance and conformity testing has been performed and certified by Electronic Technology Systems (ETS) of Germany, DAR registration number BPT-ZE-026/96-00. 4. Because radio frequency allocations have not yet been fully harmonized within the European Union, or across Europe as a whole, all Sabine True MobilityTM transmitters display a "warning sign" to indicate these products are considered "Class 2" products under the terms of RTTE Directive 1999/5/EC. CAUTION - Implanted cardiac pacemakers or AICD devices: Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wireless microphones have Iow-power transmitters (less than 0.05 watts output) that are unlikely to cause difficulty, especially if they are at least a few inches away. However, since a beltpack transmitter typically is placed against the body, Sabine suggests attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent to an implanted medical device. Note also that any medical-device disruption will cease when the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, or experience any problems with the use of this or any other RF equipment. B2-SWM-Op-Guide-v4.pmd 030108-hto
