User manual SABINE SWM7000 - QUICK GUIDE

SWM7000 Receiver & Transmitter Quick Setup 1 Please read Section Four Transmitter Operation and Section Five Receiver Operation of the operating guide for a complete understanding of how to set up your Sabine 2.4 GHz Smart Spectrum® True Mobility® System. See page 4 of this Quick Start Guide for tips on channel selection and maximizing RF performance. 1 RECEIVER & TRANSMITTER CHANNEL SELECTION 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. See step 3 for the controls used to select RF channels.

Vocal RATIO COMPRESSOR/LIMITER Vocal Settings RATIO A soft voice could be set to 2:1, whereas a loud voice might require a ratio setting of 6:1. THRESH 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. ATTACK 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. Guitar Settings A high compression ratio (with gain makeup) will add sustain to held notes and chords. THRESH Moving the threshold will change the audible thick/ thinness of the guitar tone, but generally you want to compress all the notes played. ATTACK Be wary of too quick an attack, which may reduce the percussive attack of the guitar notes. RATIO Soft voice Loud voice THRESH Soft voice Loud voice ATTACK Short attack is better for vocals. Be careful not to over attenuate speech consonants. Guitar RATIO Less Sustain More Sustain 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 Set to 4:1 THRESH Set to compress peaks only. ATTACK Quick attack, medium release, hard knee; (try various release settings, depending on the speed of notes played). GAIN Output boosted slightly. RATIO THRESH Thinner sound Thicker sound ATTACK Be wary of too quick an attack, which may reduce the percussive attack of the guitar notes.

SWM7000-Quick-Guide-070525.pmd - rr FBX Quick Setup (to be done after Transmitter and Receiver Setups have been completed) 3 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. 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. 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. Location #2 Location #3 Location #4 (if necessary) 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). 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, regardless of how or when SETUP mode is exited. See Section 14.3.2 for details on the differences between fixed and dynamic FBX filters. See 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). Bypass Button The BYPASS button 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 2007 4 RF Performance Tips 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 and keep your channels grouped together. If you hear any RF "hits" or dropouts, then try another of the 70 available channels. For best results, maintain line-of-sight from transmitter to receiver. Use either front or rear panel antenna mounting to maintain line-of-sight. This is very important! 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, as shown below. Maintain a minimum distance of at least 3 meters (10 feet) between transmitters and receivers or extension antennas. This can solve many anomalies. 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. Common Sources of RF Interference Microwave ovens Microwave ovens 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 below. Wireless Local Area Networks (WLANS) In general, Sabine microphones should not be affected by these WLANS. Use the RF scanner included in Sabine because their spread spectrum technology does not present a problem for the Sabine Smart SpectrumTM system. See caution below. 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. Wireless Video Cameras 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 below. 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.
