Receiver & Transmitter Quick Setup Please read Section Four Transmitter Operation and Section Five Receiver Operation for a complete understanding of how to set up your Sabine 2.4 GHz Smart Spectrum True MobilityTM System. 1 Selecting RF Channels: It is best to keep the system's channels close together at the low or high end of the spectrum, i.e. channels 1, 2,3,4,5 or channels 65, 66, 67, 68. If there is another 2.4 GHz source in the room, grouping the channels reduces the chances of an overlap. Do not start by spreading your channels throughout the 70 channel range of the system ­ you are more likely to encounter interference this way. Transmitter range is 100 meters line-of-sight Use Sabine's SWASS-EXT Extension Antenna Kit when line-of-sight path is not possible from receiver location. Be sure that all transmitters are off. Position receiver so that the antennas are within visual range of the intended transmitter locations. Transmitter range is about 100 meters, but structural objects in the transmission path can reduce that range. For best results, maintain a line-of-sight path between receiver antennas and transmitters (see Section 12). Use the TNC Rear-to-Front Kit (SWA700) included with the receiver to move antennas to front if necessary. See Appendix B for more information on multiple-system connection. 2 Turn the OUTPUT LEVEL of the 2.4 GHz receiver and mixer gain to the minimum settings. 3 Connect the output (¼-inch or XLR jack) of your 2.4 GHz True MobilityTM receiver to the mic or line input of your mixer or amplifier (the receiver output gain can be adjusted to match the mixer input). Mixer Balanced Input (XLR) Mixer Unbalanced Input (TRS) 4 1. Turn on the receiver. 2. Tap the Channel Select/Contrast button to edit a receiver channel. (Not necessary on 1-channel SW71-R & SW71-NDR receivers). 3. Turn the RF Channel Selector knob to the desired channel.

NOTE: the transmitter is muted during editing. SELECT 3. Use the UP or DOWN button until the desired channel appears above CHANNEL. 4. Check that the receiver's RF SIGNAL display now indicates a strong signal (at least 3 bars). 6 Gain Adjustment Settings 1. Transmitter (PAD Adjustment). Adjust the Transmitter PAD setting if last segment of the Transmitter or Receiver Audio Level Meter lights up often, or remains on when mic or beltpack is used. 1. Use the Transmitter Select button to scroll through functions until PAD flashes in the Transmitter LCD. 2. Use the Up or Down buttons to select the desired setting. Selection is stored after 3 seconds of inactivity. 3. Check to see if Audio Level Meter stays out of Clipping Zone Adjust PAD setting so that Receiver Audio Level Meter stays out of the clipping zone (last segment) 2. Receiver. Adjust the receiver Output Level to supply a strong input level to the mixer, amplifier or active loudspeaker. If your receiver output is connected to a microphone level input on the mixer, keep the receiver output gain lower than when connecting to a line level mixer input. NOTE: -10 is a good place to start. 3. Mixer. Adjust the output gain of the mixer so that the mixer output meters approach clipping when all the inputs to the mixer are active, and the audio program reaches its peak level. 4. Amplifier/active loudspeaker/crossover. Finally, adjust the amplifier gain control (and/or crossover gain, if one is used) to provide the desired level of sound pressure in the auditorium or listening area. © 2007 Sabine, Inc.

FBX Quick Setup 1 2 Place microphone and speakers in primary position. Press and hold the SETUP button (Fig. 3d) on the receiver until the LCD SETUP indicator (Fig. 3e) flashes 4 times and SETUP stays lit -- then release it. NOTE: DO NOT TALK INTO YOUR SYSTEM while in Setup Mode. Fig. 3d - FBX: SETUP Fig. 3e - SETUP indicator flashing 3 Slowly raise the gain on the mixer or amp until FBX eliminates the first few feedback tones. With each new feedback frequency, you will hear a short, quiet burst of feedback that will disappear immediately as a filter is set. Mixer Channel Location #1 4 Pause raising the gain, and move the microphone to another area where it will be used. Resume slowly raising the mixer gain, until FBX eliminates a few more feedback tones. NOTE: When choosing microphone setup locations, try to anticipate likely areas where the microphone will be positioned or moved to, or areas that may be especially prone to feedback problems (e.g., under an overhead speaker). Location #2 5 Repeat until the SETUP indicator automatically turns off and the READY indicator comes on. NOTE: You may quit SETUP mode at any time prior to its automatic exit by simply pressing the READY button. This will enable ready-to-operate status, but with fewer fixed FBX filters in place. In the default factory setting, dynamic FBX filters will still be held in reserve to catch and eliminate new feedback, reLocation #4 Location #3 gardless of how or when SETUP mode is exited. (See Section (if necessary) 14.3.2 for details on the differences between fixed and dynamic FBX filters and Section 13.4.2.1 for instructions on changing the balance of fixed versus dynamic FBX filters using the Remote Control Software or Appendix D for using the Dip Switches on the back of the receiver). 3.2.2. FBX Bypass © 2007 Sabine, Inc. The BYPASS button (Fig. 3d) bypasses only the FBX filters, and not the additional signal processing (de-essing, compression and Mic SuperModelingTM) available on the True MobilityTM Wireless Receiver. This is a useful button that allows comparison of the sound quality when FBX filters are in place, to the sound with no filters (the quality should be very similar). Before pressing BYPASS, take care to reduce your overall system gain so that you do not release suppressed feedback! FBX BYPASS CAUTION Bypassing FBX filters may allow suppressed feedback to be released! Sabine 2.4 GHz Smart Spectrum® Wireless 8 Quick Setups COMPRESSOR/LIMITER Vocal Settings RATIO Vocals RATIO A soft voice could be set to 2:1, whereas a loud voice might require a ratio setting of 6:1. The higher the threshold setting, the more signal is required to initiate compression. Ideally this should be set to reign in peak levels, and allow signals of lower gain to pass uncompressed. Threshold settings will depend on the nature and variety of the signal source. Short attack times usually work well for voice. However, too strong a compression ratio, too low a threshold, and too fast an attack may attenuate speech consonants, which provide important intelligibility cues to the audience, thus compromising clarity. THRESH Soft voice THRESH Loud voice ATTACK Soft voice ATTACK Loud voice Short attack is better for vocals. Be careful not to over attenuate speech consonants. Guitar Settings RATIO Guitar RATIO A high compression ratio (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. THRESH Less Sustain THRESH More Sustain ATTACK Thinner sound ATTACK Thicker sound In general, be wary of too much gain makeup, and too high a compression ratio, which may make a noisy guitar amplifier more objectionable. Ratio settings might range from 6 to 19:1, threshold variable, slower attack, soft knee, output gain boosted slightly to significantly depending on amount of compression. Bass Guitar Settings RATIO THRESH ATTACK Be wary of too quick an attack, which may reduce the percussive attack of the guitar notes. Set to 4:1 Set to compress peaks only. Quick attack, medium release, hard knee; (try various release settings, depending on the speed of notes played). Output boosted slightly.

Tips for Good RF Performance · It is best to keep the system's channels close together at the low or high end of the spectrum, i.e. channels 1, 2, 3, 4, 5 or channels 65, 66, 67, 68. If there is another 2.4 GHz source in the room, grouping the channels reduces the chances of an overlap. Do not start by spreading your channels throughout the 70 channel range of the system -- you are more likely to encounter interference this way. Avoid potential sources of RF interference by performing a scan using Sabine's Remote Control Software., which will reveal the ambient RF level in your area on each channel of your system. Please refer to Section 13.4.2.5. for information on the RF Scan function, which will automatically determine the best RF channels to use. If you cannot perform a scan then proceed to use your system, beginning with Channel 1. If you hear any RF "hits" or dropouts, then move to another of the 70 available channels. If you have multiple mics keep all your channels grouped together. For best results, maintain line-of-sight from transmitter to receiver. Use either front or rear panel antenna mounting to maintain line-of-sight. Mount receiver antennas at 90 degrees to one another, leaning away at 45 degree angles, in the same plane. When using multiple receivers, try to maintain at least 1 foot (30 cm) distance between antennas from different units. When such antenna spacing proves difficult or impossible, we recommend using Sabine's SWA6SS Antenna Distribution Amplifier. The SWA6SS works with up to six receivers, or 12 channels. Maximize the distance between the receiver and light sources, such as fluorescent bulbs or neon signs, which may emit very short-range, broadband interference. Maximize the distance between transmitters and receivers and potential sources of RF interference. Maintain a minimum distance of at least 3 meters (10 feet) between transmitters and receivers or extension antennas. This can solve many anomalies. Turn on your system one component at a time, beginning with the first receiver. Be careful not to set more than one transmitter to the same channel; each paired transmitter and receiver should be set to unique corresponding channels, until all channels are receiving clearly and cleanly. · · · · · · · · Antenna Placement Caution · As a general precaution, keep 2.4 GHz cordless telephones, microwave ovens, WLAN antennas and 2.4 GHz wireless video camera transmitters twice the distance from your Sabine wireless microphone system antennas as that of your Sabine 2.4 GHz transmitters. · 3.4. Common Sources of RF Interference · Microwave ovens: In the vast majority of situations, interference from microwave ovens will not affect performance of your SWM7000 series microphone systems. Since barriers such as walls work to block interference, a microwave oven will likely present a problem only when located in fairly close proximity within the same room as the wireless receiver (or reception antenna). See caution at left. Wireless Local Area Networks (WLANS): These computer network devices allow computers to connect via wireless devices that act as both receivers and transmitters. These low-powered transceivers often have selectable channels and can utilize the entire 2.4 GHz band. In general, Sabine microphones should not be affected by these WLANS because their spread spectrum technology does not present a problem for the Sabine Smart SpectrumTM system. The Sabine wireless system will not interfere with the WLAN. See caution at left. · © 2007 Sabine, Inc. Sabine 2.4 GHz Smart Spectrum® Wireless 10 · 2.4 GHz Cordless phones: These home telephones broadcast at very low power and should not present interference problems for your Sabine wireless. This is especially true if the telephone uses spread spectrum technology. See caution at left. Wireless Video Cameras: Certain wireless video cameras (X10, for example) use the 2.4 GHz band. These devices are also very low power and, in general, should not present a problem when using the SWM7000 system. See Section 5 Receiver Operation for methods of optimizing clear reception and minimizing interference. See caution at left. · In the event problems still arise, see Section 5 Receiver Operation for methods of optimizing clear reception and minimizing interference. © 2007 Sabine, Inc. 11 Sabine 2.4 GHz Smart Spectrum® Wireless LIT-SWM7000-OG-EN-070615.pmd - rr Transmitter Operation Fig. 4a TA4F connector 4. TRANSMITTER OPERATION 4.1. First step Before you begin, let's look at a few basics regarding your transmitters. The handheld mic is ready to go -- the microphone and transmitter are combined in one unit. To use the belt pack transmitter, however, you will have to connect a lavalier or headworn microphone (or instrument pickup) to its input. Sabine lavalier and headworn mics, and Sabine's guitar/instrument connector (SW70G-TA4) come equipped with the proper TA4F connector, and are ready to plug right in. Be sure to line up the pins properly -- do not force the connector into the belt pack. If you are using a different microphone with the Sabine belt pack, please refer to the Appendix A for the required wiring plan. Failure to use the proper wiring scheme may damage your mic or the belt pack, and void your warranty. Use the clip on the back of the belt pack transmitter to attach it to your belt or clothing. The spring clip can be removed and reversed, to allow the transmitter and antenna to point either up or down in its clipped-on position. You can also remove the clip if you choose to keep the transmitter in your pocket. NOTE: it is essential that transmitters retain a line-of-sight relationship with the receiver antennas. External Switch Fixed Antenna Belt clip 4.2. Displays and Settings 5 4 2 Your Sabine 2.4 GHz Smart Spectrum handheld microphone and belt pack transmitter have many powerful features, all of which are easily monitored (using the transmitter LCD display) and adjusted. The controls and displays for both handheld and belt pack transmitters are almost identical in function, though positioning differs (compare figures 4b & 4c). The LCD display and one control switch are located on the exterior of the transmitters. A more powerful set of recessed controls is located under the hinged access panel, to prevent accidental or inappropriate alteration of settings. 6 4.2.1. LCD Display When the transmitter is first turned on, it shows an initial test screen (Fig. 4f), followed by the default screen (Fig. 4g). The LCD also reverts to this default display within a few seconds after any programming changes are 1 made with the recessed controls. The default LCD display always shows 3 transmission channel, audio level, and battery voltage level; additional Fig. 4b SW70-H1 Handheld Control Setting Buttons information will appear to indicate important changes caused either by user adjustments, or automatically as transmitter status changes. 2 1 O N /OFF O N /M UT E O N /ON 6 4 SELE CT D OW N UP 3 Fig. 4c SW75-T Transmitter Control Setting Buttons 1.

You are required to choose the input in order to program both the transmitter and the receiver to optimize the input settings. Choosing MIC automatically selects the 75 Hz roll-off filter. You can choose to remove that but the extended low frequency response of the SW75-T may reproduce too much low energy for your system, so beware. Choosing INSTR automatically removes the 75 Hz roll off filter for that added bottom end in your instruments. NOTE: You can manually change that filter setting as needed. Electric Guitar/Bass & FBX: For best results, when using the SW75-T Beltpack Transmitter for electric guitar or bass, put your receiver's FBX Feedback Exterminator into BYPASS mode. FBX BYPASS is accessible via the receiver front panel or Remote Software control. Guitar Cord Simulator (Beltpack Transmitter Only) This feature allows you to fine tune the sound of your instrument while it is patched into your Sabine wireless beltpack.

The Up/Down buttons will adjust attenuation (SW70-H1: 0, -6, -14, -20 dB; SW75-T: 0, -3, -6, -10, -14, -17, -20, -23, -26, -30, -34, -37, -40 dB). When any level of attenuation is programmed, the default screen will illuminate PAD. See margin notes on this page and p.15 for settings instructions. TIME: Battery Run-Time Hours. Selecting this option changes the display to indicate the length of power-on time (hours and minutes) since the last battery change or recharge. NOTE: Battery run-time hours will reset when the transmitter (with battery in place) is connected to a charger. In the case of the charger, run-time hours will not start again until the charger is disconnected. You can manually reset the run-time hours by pressing both the up and down arrows. Use this to count hours when you use alkaline batteries. LOW FREQUENCY ROLL-OFF: Selecting this option adds a 12 dB/octave low frequency roll-off filter, starting at 75 Hz, to the audio output of the transmitter. A roll-off filter may help reduce microphone handling noise, or other unwanted low frequency content. Pressing the Up or Down button toggles between the conditions of no filter (indicated in the display as L 0) or low rolloff (indicated by L 75). INTERNAL CONTROL OF EXTERNAL SWITCH: The recessed controls include a 3-position switch, which in turn determines how the transmitter's external two-position switch behaves (see figures 4a, 4b & 4h). From left-toright, the 3 positions of the internal switch correspond to the following external switch operations: 14 Transmitter Operation 1. ON/OFF. In internal position #1, the external switch acts as a typical on/ off switch. Use this setting if you trust the microphone user to switch the microphone on and off as needed, and/or wish to conserve transmitter battery life during down times. In the ON position the transmitter LCD will display ON. Both audio and RF are on. In the OFF position the LCD ON is no longer illuminated. Both RF and audio are off, and the battery run-time hours meter is off. Note that Sabine's squelch system prevents any "popping" when switching the transmitter on and off. However, this protection causes a very short "power-on" delay in the reactivation of the audio when the external switch is turned from OFF to ON. ON/MUTE. In internal position #2, the external switch acts as a typical mute switch. Use this setting if you trust the microphone user to switch the microphone audio output on and off as needed; it will not conserve battery life in MUTE condition, but will allow the receiver to monitor and display the RF signal strength in either switch position. In the on position the default LCD will display ON. Both audio and RF are on. In the off position the word MUTE is displayed in the LCD. The audio is muted but the transmitter is still transmitting the RF signal, and the battery runtime meter is running. There are no audible pops when switching the transmitter between MUTE and ON. Switching from MUTE to ON will instantaneously pass audio signal (there will be NO delay as with internal position #1). ON/ON. In internal position #3, the external switch is disabled. The transmitter (both RF and audio) is always on, and the word ON is always displayed in the transmitter LCD screen. Use this setting if you do not want to allow the speaker or performer to turn off the transmitter, or are worried that a transmitter may be accidentally turned off. Caution: When your program is over we suggest you move this switch to another setting so you can turn off the transmitter and save your battery. You may also elect to remove the battery (though replacing the same one will restart the run-time meter and affect its accuracy accordingly). Beltpack Transmitter PAD Settings The SW75-T beltpack transmitter has a broad range of PAD settings, which allow you to use it with almost any microphone or instrument. As in all audio equipment, the setting of the input level is crucial to achieving the best sound quality. Setting minimal PAD levels (-3, -6, or -10 dB) may produce a distorted sound if you are using a high output microphone or instrument. Conversely, setting a more extreme PAD level (-40, -37, or -34 dB) may require you to raise your system gain unnecessarily, resulting in a noisier output. Watch the input meter on either the transmitter or the receiver (see illustrations) and set your level so there are at least three indicators illuminated for normal program level, with an occasional move to the fourth indicator. The fifth and biggest indicator denotes clipping ­ watch out! If you see clipping, choose a lower pad setting (for example, from -10 to -14 dB). 2. Transmitter PAD Adjustment (See Fig. 4c, 4f & 4g) 1. Use the Transmitter Select button to scroll through functions until PAD flashes in the Transmitter LCD. 2.

Once you have completed the transmitter setup, you are ready to work with your receiver (see Section 5). First, however, let's talk about the issues and solutions concerning the source of transmitter power: the battery. 4.2.4. Transmitter Battery Management 4.2.4.1. Battery problems and Sabine solutions Rechargeable Battery memory. Batteries that are repeatedly recharged prior to a complete discharge may fail more quickly in subsequent uses. This problem is usually referred to as "battery memory." Fortunately, Sabine's innovative Tireless WirelessTM Charger takes steps to avoid this problem, by automatically reconditioning the battery whenever its intelligent diagnostics determine this is appropriate. Sabine's Tireless WirelessTM Charger will insure maximum life per battery charge, and also prolong the useful multiple-charge life span of rechargeable batteries. Battery life. Both handheld and beltpack transmitters can work with disposable alkaline, disposable heavy-duty (manganese dioxide-carbon zinc), or rechargeable Nickel Metal Hydride (NiMH) batteries. We specifically caution against using NiCad rechargeables due to wellknown battery memory problems, and specifically recommend using the Sabine-supplied SWBAA2 (AA for the H1 Series handhelds and beltpack) batteries. The rechargeable SWBAA2 batteries will last about 8 hours per recharge (typically, alkaline AA batteries will last about 10 hours). NOTE: Heavy-duty batteries will fall somewhere in the middle, between rechargeables and alkalines. -17 dB -23 dB -26 to -34 dB -37 dB See the Transmitter Quick Guide that came with your transmitter for a complete look at the suggested pad settings.

Here are several more good reasons why you can feel more confident about using rechargeable batteries: 1. All transmitters report two types of battery status information. The first report is the all-important voltage the battery is supplying. Second, you'll know how long the battery has been in use (battery run time hours). Each receiver channel also receives telemetry information from its associated transmitter, regarding the battery voltage, and displays the information in the receiver LCD (see figure 5b). When the voltage reaches a level indicating an estimated 30 remaining minutes of useful battery life, both transmitter and receiver automatically flash warnings in their LCD displays. As an alternative means of anticipating battery depletion, you can check the number of hours of use, by checking the transmitter LCD display (see Section 4.2.2 and figure 4g), or the Remote Control Software. 2. The handheld microphone clip that we provide with each handheld transmitter not only holds the microphone -- it also can double as an unobtrusive charger housing. Anytime the mic is parked in the clip (and the clip is connected to the charger power supply), the mic is being charged. As an additional safety margin against battery failure, the mic placed in the powered clip gets its power from the charger, not the battery, so it will work perfectly even if the battery is completely dead. Sabine's intelligent charger circuitry detects the type of battery in place within the battery compartment, and automatically turns off the charger if the battery is not compatible with the charger. The Tireless WirelessTM Charger detects when a battery is fully charged, and turns off the charging cycle. The Tireless WirelessTM Charger prevents futile attempts to resuscitate dead batteries -- if the battery is unresponsive, the charging cycle is stopped. Beltpack and handheld batteries can be recharged without removing them from the transmitters. Just connect charger plug to the transmitter jack (see Fig. 4l). WARNING! DO NOT USE Alkaline Rechargeable Batteries Alkaline Rechargeable 3. Alkaline "AA" Rechargeable Batteries 4. 5. 6. FIRST-TIME BATTERY CHARGING Your Sabine True Mobility® transmitter comes with one or more rechargeable NiMH batteries. For best results, charge the battery for at least 8 hours before using it for the first time. Please note that the full charging potential of the battery will be achieved after the first 5 charging cycles have been completed. NiMH rechargeable batteries are highly resistant to "memory effect," which affects some other rechargeable batteries. The included NiMH batteries will provide more lifetime charges and longer battery life for each charge than many other rechargeable batteries. NOTE: In the "most discharged" battery condition, a full recharge may take up 8 to 12 hours depending on the mA value of the AA batteries used with the handheld and beltpack transmitter. The charging system will charge a batteries with a mA value of up to 2400. When in doubt, charge the batteries overnight. Sabine's battery-protection circuit will shut the charger down when charging is completed. © 2007 Sabine, Inc. BEFORE CHANGING BATTERY Turn off transmitter before changing battery(s). Sabine 2.4 GHz Smart Spectrum® Wireless 16 Transmitter Operation 4.2.4.2. Charging Your Batteries Equipment Connections. Each SW75T or SW70H1 transmitter comes equipped with an SWC-POWR Tireless WirelessTM plug-in charger (see Fig. 4l). In addition, each SW70H1 comes with its own battery-charging mic clip (SWC70-CL). The SWC-POWR charger can be plugged directly into either the transmitter or into the clip. A Sabine rechargeable battery (SWBC1) will charge whenever the mic clip is connected to the Sabine SWC-POWR charger and the handheld is properly placed within the mic clip. Charging Indicators. Much like your cell phone, the transmitters will let you know the charging status of the battery. When the battery is charging, the battery meter will flash to indicate the relative level of the charge -- one, two, three or four elements will flash (see Fig. 4i). Once the battery is fully charged, all four elements in the battery meter will flash. This indicates that the charging circuit is no longer on (see Fig. 4j). NOTE: The right-side indicator segment will flash for several minutes when charging is first attempted (see Fig. 4h). The lower the battery level, the longer this initial "testing/not charging" flashing sequence will continue. During this time, the Tireless Wireless battery circuit is evaluating the suitability and charge status of the battery in place. When it has completed its evaluation, it will either commence the progressive flashing depicted in figure 4i (CHARGING), or continue to flash (TESTING/ NOT CHARGING). All segments flashing in unison signifies that the battery is fully charged (see Fig. 4j). These same indications will also be displayed on the receiver LCD, and on the Remote Control Software screen. NOTE: The Tireless Wireless battery charger will only charge NiMH rechargeable batteries. If you place any other kind of battery in the transmitter, and then attempt to charge it by connecting the charger, the Tireless Wireless circuit will detect the type of battery and will not begin charging. Again, the battery indicator on the transmitter will flash the right-side element indicating testing/no charging (see Fig. 4h). Battery Warnings. When the transmitter battery voltage drops below a critical threshold, the battery icon (which normally displays the voltage level) will begin to flash. This will occur on the transmitter and receiver and is an indication that you need to replace the battery, or charge it by placing the handheld mic in the charger clip. NOTE: Microphone will still transmit audio when placed in clip. Alternatively, you can connect the charger directly to the transmitter using the built-in charger jack located on the side of the beltpack transmitter and near the antenna on the handheld transmitter (see Fig. 4l). If the battery is not changed or recharged, the transmitter will eventually turn off (see Fig. 4k). Fig. 4h: TESTING/NOT CHARGING Right-side battery indicator segment will flash to indicate that the battery is being tested. This occurs prior to charging a NiMH battery and whenever a nonrechargeable battery is placed on charge. Charging is not occuring when indicator lights in this fashion. Fig. 4i: CHARGING Battery indicator segments will flash progressively starting from the relative charge state of the battery. This example depicts a fully discharged battery being charged. As the charge progresses, left-side segments will remain visible as right side segments continue to flash, until all segments are visible. At that point, all segments will flash on and off in unison (see Fig. 4j). Fig. 4j: FULL CHARGE Battery indicator segments will flash in unison to indicate that the battery is fully charged. NOTE: Battery can be left connected to the charger and will receive periodic maintenance charging. Fig. 4k: Battery CHARGE LEVEL displays Fully Charged Partially Used Very Used Very Low (Flashing) SW75T NOTE: When the battery has reached a specific discharge level, the transmitter will automatically turn off, and the transmitter LCD will display the message at right. © 2007 Sabine, Inc.

Parameter Control & LCD Display 5.2.1. One set of Controls for 1 or 2 Channels Whether you have a one- or two-channel SWM7000 series receiver is apparent by the number of LCD displays on the front panel. However, only one set of control knobs is provided for either one- or two-channel receivers. Note that in a 2-channel receiver, this set of controls is shared, and assigned to a channel by pushing either the A or B Channel Select button (see Section 5.2.2). Your SWM7000 Series receiver uses Sabine's Tweek-n-PeekTM digital control system. Whenever you turn a control knob one click, the associated function is shown on two lines of text display in the LCD. The large numeric display will indicate the current parameter value. Additional turns/ clicks change the parameter setting and display the value as the change is made. After a few seconds of inactivity, the LCD will revert to its default display (RF channel). Fig. 5c Sabine Tweek-n-Peek Sabine's Tweek-n-PeekTM Whenever you turn a control knob one click, the name of the corresponding function is shown and the current edit setting is displayed on the LCD. This applies for all the front panel knobs. For example, if you turn the Compressor ratio knob one click, you will see the current compression ratio in the Settings Display. The Text display will show COMP on the first line and RATIO on the second. Subsequent turns will edit that setting up or down, depending on the direction you turn the knob. Since the control knobs are continuous rotary encoders with no end points, the Relative Position Indicator (RPI) is a handy way of seeing where you are in relation to the full range of the knob in question. In our compressor Ratio example, if you are at a ratio of 9:1, about the middle of the range, the RPI will display about one half of the bar. NOTE: The setting range of each control is printed on the front panel below each knob. Relative Position Indicator In our compressor Ratio example, if you are at a ratio of 9:1, about the middle of the range, the RPI will display about one half of the bar. EDIT will light in the channel display of the channel being edited. Function Display The Function display will show COMP on the first line and RATIO on the second.

Range of value is 1 - 30, 15 is default. 5.2.2. Channel Select / Contrast Button. The elliptical button immediately adjacent to the LCD has multiple functions. First, it adjusts the LCD contrast and viewing angle. Change the degree of angle by pressing and holding the button down. The adjustment range will cycle in a continuously reversing loop -- when it gets to the maximum value it reverses and begins to decrease in value. You can stop holding the button down and initiate single button pushes to advance (or decrease) the contrast setting incrementally. In addition, the Contrast/Channel Select button has another function, in 2-channel receivers only (SWM72-R or SWM72-NDR). Such units feature two LCDs and two Contrast/Channel Select buttons. A single (without continuing pressure) push assigns all Parameter Control knobs to the selected channel. The button will light, the associated LCD will brighten, and the word EDIT will appear in the lower left of the LCD, all indicating the active edit channel. For the active channel, turning any Parameter Control knob will first display (one click) and then adjust (subsequent turns) the settings of the function selected, indicating the changes in the Settings Display. For the inactive channel, turning any Parameter Control knob will display the current setting in that channel's Settings Display. The channel must be activated in order to change settings. Sabine 2.4 GHz Smart Spectrum® Wireless 20 Receiver Operation 5.2.3. Special LCD Display Messages. In addition to the Status and programmable information discussed above, the text lines of the LCD Settings Display may also (under certain circumstances) automatically override other displays. The conditions when this will occur and the messages displayed are shown on page 19. 5.3. RF Channel Select Range = 1 to 70 Choose the RF channel for this system. The transmitter must have the same channel selected. Turn the RF CHANNEL SELECT knob until the desired channel is displayed on the LCD. See chart (Appendix E) for exact frequency of each channel. NOTE: Dual channel receivers will not allow you to select the same RF channel for both channels. NOTE: Front panel RF Signal display will only register Sabine transmitters. It will not show RF interference. Use the RF Scan function in the software to scan for potential RF interference (see Section 13.4.2.5). Fig. 5f 5.4. Output Level Range = MUTE to 0 dB Adjust the output level to match the input characteristics of the downstream component. Each tick of the output level knob adjusts the level by ½ dB. The LCD displays this in 1 dB resolution, so it takes two ticks of the knob to change the output level value on the LCD. The output level varies from microphone level to line level, so if you are patching the receiver to the mic level input of a mixer, turn down the level to avoid overdriving the mixer input. Minus 15 dB is a good place to start. If you are patching into a line level device, turn up the receiver output. For best results, follow the golden rule of gain structure: maximize gain at early stages in the signal path, to minimize noise that will be accumulated and amplified by adding late-stage gain. Fig. 5g 5.5. Channel Mixing Your SWM7000 Series two-channel receiver now has the ability to mix the A and B outputs. In Channel Mixing mode both the A channel audio and the B channel audio are mixed together, and are available on both the A and B outputs.This is an advantage for several applications: EXAMPLE: Guitarists who wish to have a spare guitar ready to go without repatching the output of the receiver to their pedal board or other processors. All you have to do is turn the transmitter off for one guitar and turn on the other. The audio is sent out through the same output of the receiver. EXAMPLE: Sound techs who wish to use more mics than they have channels for on their mixer. For example, you may have a mixer with only 8 inputs, but you really need 12 mics for a show. You can combine the outputs of several pairs of Sabine wireless mics and the show can go on without buying a new mixer. You maintain separate control over all channel functions except output level. Output levels are the same for both channels when in Channel Mixing mode, and the ouput values appear on the A channel LCD. 5.5.1. How to Toggle Channel Mixing Mode Press and hold both the A and B Channel Select buttons (the blue buttons) at the same time. After a moment both buttons will be lit. This is your indication that you are in Channel Mix mode. To go back to the standard mode, press and hold the A and B channel select buttons again until the backlight of one of the buttons turns off.

Use the Channel Select buttons to choose the channel you wish to control. In Channel Mix mode you still use the Channel Select buttons to choose the channel to control, but you will only see one of these three indicators. The word EDIT will be shown in the LCD of the channel selected for control. Look carefully ­ this is your only indication of which channel you are controlling Fig. 5i 5.6. Guitar Cord Simulator (Beltpack Transmitter Only) This feature allows you to fine tune the sound of your instrument while it is patched into your Sabine wireless beltpack. The wireless sounds of guitars or basses can be very different from the direct (patched with a cord) sounds. Your Sabine 2.4 GHz wireless solves this problem by using a unique broadcast scheme that gives full 20 to 20KHz frequency response. This results in a much fuller sounding instrument (the bass response is finally there on a wireless!), and sometimes a brighter sound, too. How can this be? Your guitar cable can actually reduce your high frequency response. We are all quite used to this slight rolling off of the high end, but the Sabine wireless does not roll off, so your instrument may sound brighter then ever before. Here's where the Cord Simulator can help. Turn on your beltpack transmitter and put it in GUI mode. To select GUI mode, open the beltpack, push the select button a few times until you see the MIC or GUI display. Use the up/down button to choose GUI. (See the Beltpack Quick Guide for detailed instructions). The DeEsser knob on your receiver becomes your Cord Simulator knob. Turn the knob counter-clockwise until your instrument sounds like it does when patched direct. The Cord Simulator replaces the De-Esser function only when a beltpack transmitter is turned on and set to GUI mode. Fig. 5j 5.7 Receiver Antenna Placement . Fig. 5k One of the biggest potential problems in any wireless system is RF interference. Understanding wave interference patterns will help you to place and orient your receivers and antennas properly, and thereby reduce the likelihood of RF interference. Your SWM7000 series receiver ships with two standard coaxial bipole antennas. Each antenna picks up in a donut-shaped (toroidal) pattern, more or less equally in all directions, with null points directly above and below. 5.7 .1. Multi-path Interference Like sound waves, radio waves are subject to wave interference patterns produced by reflected or delayed waves combining with direct, unreflected waves, converging upon a receiving antenna simultaneously. In the RF world this phenomenon is called multi-path interference. As with audio comb filtering, radio waves can combine additively or subtractively. Thus, mounting an antenna close to a reflective surface can result in poor reception. For example, if weaker than expected reception occurs, and the receptive part of the antenna (the top 3 cm) is close to a reflective surface (wall, large metal objects, etc.), you might improve reception simply by repositioning, or re-aiming, the antennas. In some situations -- for example, those with difficult lines-of-sight, or when transmitters and receivers are separated by a wall, or when receiver placement options are limited -- an extension antenna may be necessary to guarantee reliable reception. Please refer to Section 12 for information about the advantages and use of Sabine's SWASS-EXT Extension Antenna Kit. 5.7 .2. Receiver & Antenna Placement Tips 1. When possible, maintain line of sight from transmitter to receiver. Consider the potential range of transmitter "roaming," and locate your receiver accordingly. If direct line of sight proves impossible or difficult, consider using Sabine's low-profile, active Extension Antenna Kit (SWASS-EXT), which boosts the signal strength, extends the maximum distance from © 2007 Sabine, Inc. Sabine 2.4 GHz Smart Spectrum® Wireless 22 Receiver Operation transmitter to receiver, expands and focuses antenna sensitivity, and allows antenna and receiver to be positioned further apart or in separate rooms. 2. Decide on front or rear panel antenna mounting (to maintain line-ofsight path). Antennas typically mount on the rear panel of your receiver, but the included accessory SWA700 front mounting kit can be screwed onto the front and connected via jumper to the back panel terminals. When mounting receivers in a rack that is deeper than the receiver, move the antennas to the front for improved reception. For any rack mounted receiver, try to keep the top 1.25 " (3 cm) of both antennas extended outside the sides of the rack (see Fig. 5h). Non-rack mounted receivers should be oriented so that the antennas face the transmitters. Maximize the distance between the receiver and light sources, such as fluorescent bulbs or neon signs, which may emit very short-range, broadband interference. These light sources should not be a problem in normal circumstances, but, as a cautionary preventative, we recommend a minimum distance of 3 meters (10 feet) between them and any receivers or extension antennas. Note the placement of any microwave ovens in the immediate vicinity. Place any receivers or extension antennas as far away as is practical from microwave ovens. Mount receiver antennas at 90 degrees to one another, leaning away at 45 degree angles, in the same plane. This will decrease the likelihood that one antenna will be susceptible to the same orientation-specific directional or multi-path problems that may affect the other one. When using multiple receivers, try to maintain at least 1 foot (30 cm) distance between antennas from different units. If you are rack-mounting multiple receivers, you may want to avoid spacing them in adjacent rack spaces, to maintain distance between antennas. When such antenna spacing proves difficult or impossible, we recommend using Sabine's Antenna Distribution Amplifier (Sabine SWA6SS), which can help manage antenna configurations and, more importantly, improve system-wide interference rejection. The SWA6SS works with up to six receivers. In very rare instances, poorly shielded or malfunctioning computers or digital effects units may cause RF interference. You can test whether such units are the sources of such interference by switching them off one at a time, and determining if interference rejection improves. Turn on your system one component at a time, beginning with the first receiver. If you don't have a computer handy, keep all other receivers and transmitters switched off for the time being. Use the RF Scan function included in the Remote Control Software. This will give you a picture of the potential interference in your area, both real-time and over time. Please refer to Section 13.4.2.5. for information on Sabine Remote Control Software's Automatic RF Scan function, which will automatically determine the best RF channels to use. 3. 4. 5. 6.
