Rack mounting the Receiver There are 2 options available for rack mounting the WS-16U receiver: singly or sideby-side with another WS-16U Series receiver. a. Single mounting: Remove the receiver SIDE MOUNT CLIP (1) from each side of the receiver (as shown) and slide in the optional ERM-12 RACK EARS (2). b. Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (1) from both WS-16U receivers, join the two receivers with the EJC-2 JOINING CLIP (3) and attach the ERM-22 RACK EARS (4) as shown. (Note: Do not mount the receiver in a rack directly above an amplifier or other source of high heat - this could degrade the performance of the WS-16U. Always ensure adequate airflow and heat dissipation in any rack configuration.) 2. Powering the Receiver Plug the 18V AC/DC ADAPTER (5) provided into the DC INPUT JACK (9) on the back of the receiver. Then plug the power supply into an AC outlet. Press the POWER SWITCH (11) once to turn on the receiver. The POWER ON LED (12) will now light and the receiver is operational. 3. Antennas The WS-16U receiver is equipped with attached dual FOLDING ANTENNAS (15). These should be extended fully to obtain maximum range. Optimal positions of the antennas are 45 degrees from the receiver (at 90 degrees from each other). For maximum range, it is always best to maintain a line of sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible. 4. Mute (Squelch) Adjustment In normal operation, the SQUELCH CONTROL (6) should be set fully clockwise to the factory preset RF level (Max. Sens.). However, in areas of high RF activity, the squelch (or mute, as it is sometimes called) may need to be adjusted to compensate for the adverse conditions in a particular location. If, with the transmitter off, the receiver’s A and/or B DIVERSITY LED INDICATORS (13) flicker or stay on, the squelch control should be turned counterclockwise until the A and/or B LEDs extinguish. When the squelch is properly adjusted, the A and/or B LEDs will only light when the system transmitter is turned on. Turning the squelch control too far counterclockwise will reduce the range, but yield a quieter squelch (mute) function. During operation, especially at ranges greater than 75 feet, one or the other of the A or B LEDs may extinguish briefly. This is normal-the unit’s DigiTRU Diversity™ reception ensures that the received audio will not be interrupted. When both LEDs extinguish, the transmitter is out of range for that given location, and the user should move closer to the receiver to re-establish the radio link. (Note: Scratchy noises can sometimes occur when some electric guitars with dirty pots or connections are used with any wireless system. Therefore, the supplied INSTRUMENT CORD (34) has a factory-installed capacitor inside the 1/4" plug. This capacitor provides first order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still give you scratchy noises, we suggest these steps to eliminate them: 1) Make sure all guitar volume and tone pots are clean and all contacts are solidthis is very important. 2) A 47pf capacitor soldered across the hot to ground terminals of the guitar’s volume and tone pots will provide extra filtering.) 7. Microphone Use (with either a lavalier or head-worn microphone) Secure the connection from the LAVALIER (36) or HEADWORN MIC CORD (35) by turning the slip ring on the plug into the transmitter clockwise to thread it on to the jack. To unplug, reverse the process. To use the lavalier mic, attach it at chest level. Do not place it too close to the mouth-a distance of about six inches usually works best. To use the head-worn mic, place it on the head and adjust the boom so that the mic is about one inch to the side of the front of the mouth. As the microphone cord also serves as the antenna, be sure to extend it fully. Rolling up or shortening the cord may reduce the effective operating range-keep it as straight as possible. When ready to speak, slide the AUDIO SWITCH (31) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above WS-16U receiver instruction [Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling and screeching) will be avoided. Please also note the pickup pattern characteristics of the microphone selected. Omnidirectional mics pick up sound equally from all directions, and are prone to feedback if not used carefully. Unidirectional mics are more resistant to feedback, but pick up sound sources best that are directly in front of the mic. Also, mics that are farther from the sound source, such as lavaliers, require more acoustic gain and thus are also more prone to feedback than close-source mics such as handheld or head-worn models that are used close to the mouth]. For optimum performance, an INPUT LEVEL CONTROL (37) is provided. Adjust the gain by turning the control with a small screwdriver. For lavalier mic use, it is recommended that the level be set at about 2/3 maximum. For head-worn mic use, it may be advisable to turn the gain down somewhat, depending on the volume levels expected. In either application, experiment and set for maximum possible gain without audible distortion on the high level peaks. (Note: Turning down the gain too much can compromise the signal-to-noise and is not recommended.) BT-16U BODYPACK MICROPHONE TRANSMITTER 1. Open the battery door and insert 2 fresh AAA ALKALINE BATTERIES into the BATTERY COMPARTMENT (27), observing the correct polarity. Fresh alkaline batteries can last up to 5 hours in use, but in order to ensure optimum performance, it is recommended that the batteries be replaced after 3-4 hours of use. 2. The BT-16U is supplied factory preset for instrument, lavalier, or headset mic use. It can only be used for the preset applications or audio will not be optimal - a muddy or distorted sound may result. 3. The BT-16U is provided with a 3.5 mm LOCKING JACK (28) for connecting the audio input selected. Connect either the INSTRUMENT CORD (34) or the HEADWORN MIC (35) or LAVALIER MIC CORD (36) as desired, according to the unit type supplied. To secure the connection, turn the slip ring on the plug clock wise to thread it on the jack. To unplug, reverse the process. Slip the transmitter into a pocket or CLIP (29) it onto your clothes or instrument strap (if using the BT-16U as an instrument transmitter). 4. Channel Selection Turn the frequency agile rotary DIP switch (30) to one of the sixteen channels. The knock on the shaft should match a number of the dial, which indicates the selected channel. This step must be repeated any time for selecting a new channel. 5. Turn on the BT-16U by sliding the AUDIO SWITCH (31) to the OFF position first then slide the POWER SWITCH (32) to the ON position. The Bi-Color LED indicator (33) will stay on (GREEN), indicating usable battery strength and that the transmitter is on. In the case of dead or low batteries, the LED will either not go on at all or will stay on (ORANGE) continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life, turn the transmitter off when not in use. The A or B Diversity LED indicators (13) on the WS-16U receiver should now be lit, indicating a received signal from the transmitter. 6. Instrument Use Secure the connection from the GT cable (34) by turning the slip ring on the plug into the transmitter clockwise to thread it on the jack. To unplug, reverse the process. Plug the 1/4" phone plug into the instrument. When ready to play, slide the AUDIO SWITCH (31) to “ON” position. Adjust the volume of the receiver as per the Audio Output Instrument Connection section of the above WS-16U receiver instruction. (Note: The INPUT LEVEL CONTROL (37) is deactivated and not used when the BT-16U is in INSTRUMENT mode. Levels should be adjusted with the volume control of your instrument.) 5. Channel Selection Turn the frequency agile rotary DIP SWITCH (16) to one of the sixteen channels. The knock on the shaft should match a number on the dial, which indicates the selected channel. 6. Audio Level and Peak LED Indicator (AF) The WS-16U receiver is equipped with a 5 segment LED AF LEVEL DISPLAY (14). Occasional flickering of the top AF Peak LED indicator on loud inputs to the transmitter is normal. If this LED lights continuously, but if the LED stays lit continuously, turn down the INPUT LEVEL CONTROL on the transmitter, or noticeable distortion may result. 7. Connecting the Audio Output The WS-16U receiver provides both a fixed mic level BALANCED MIC AUDIO OUTPUT XLR (7) and an adjustable line level AUX AUDIO OUTPUT 1/4" jack (10). (Note: As when making any connection, make sure the amplifier or mixing board volume is at the minimum level before plugging in the receiver to avoid possible sound system damage.) Microphone Connection (Using the BT-16U transmitter with either a head-worn or lavalier microphone or the HT-16U handheld microphone transmitter) For microphone use, either the BALANCED MIC AUDIO OUTPUT XLR (7) or the 1/4" line level AUX AUDIO OUTPUT (10) can be used. The XLR output is set at a non-adjustable microphone level, similar to hardwired mic levels. Plug an XLR connector into the XLR output socket on the rear of the unit and plug the other end into your amplifier or mixing board. Make sure the phantom power on your mixing board is turned off and the volume is turned down when making connections. For your convenience, the XLR output level is preset at the factory and is not adjustable with the receiver volume control. To use the 1/4" AUX AUDIO OUTPUT socket, follow the instructions for the Instrument Connection (above), except start the receiver volume at 1/2 MAX and adjust until the volume level is optimal. If the volume control is set too high, you may overload your mixer or amp. The WS-16U receiver is equipped with a 5 segment LED AF level display (14 ). Occasional flickering of the top AF Peak LED indicator on loud inputs to the transmitter is normal. If this LED lights continuously, decrease the volume to the transmitter or overload distortion may result. (Note: The BT-16U is supplied with a removable antenna. It should be operated with the supplied antenna all times. For optimum operating range, always maintain lineof-sight between the transmitter and the receiver whenever possible.) HT-16U HANDHELD MICROPHONE TRANSMITTER 15 15 1. Unscrew the BATTERY COMPARTMENT COVER (17) and remove, exposing the BATTERY HOLDER (18). Insert 2 fresh AA ALKALINE BATTERIES (19), observing the correct polarity as marked, and screw the cover back on to the microphone. Make sure the cover is screwed on completely. Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure optimum performance, it is recommended that you replace the batteries after every 7-8 hours of use. 2. Channel Selection Turn the frequency agile rotary DIP switch (20) to one of the sixteen channels. The knock on the shaft should match a number of the dial, which indicates the selected channel. This step must be repeated any time for selecting a new channel. 12 11 16 14 13 10 3. Turn on the HT-16U by sliding the AUDIO switch (21) to the OFF position first. Then slide the POWER switch (22) to the ON position. The TX LED indicator (23) will stay on. The BATTERY indicator LED (24) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, the LED will either not go on at all or will stay on continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life, turn the transmitter off when not in use. 4. For optimum performance, an INPUT LEVEL CONTROL (23) is provided. Adjust the gain by turning the control with a small screwdriver. It is recommended that the level be set at about 1/2 maximum. Experiment and set for maximum possible gain without audible distortion on the high level peaks. (Note: Turning down the gain too much can compromise the signal-to-noise and is not recommended.) 5. The microphone is now ready to use. The A and/or B DIVERSITY LED INDICATORS (13) on the WS-16U receiver should now be lit, indicating a received signal from the transmitter. When ready to speak, slide the AUDIO switch (21) to the ON position. Adjust the volume of the receiver 25 as per the Audio Output Micro19 phone Connection section of the above WS-16U receiver instruc18 tions. [Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided. Note: 20 The windscreen of the HT-16U functions as a built-in antenna. For proper operation, never remove 21 the windscreen during use, or 22 17 exchange with another type. For 24 optimum range maintain line-of23 sight between the transmitter and the receiver whenever possible. Holding the microphone tightly, bridging across the windscreen and mic tube, will also lessen range. Hold by the mic tube housing only for optimum operation.]
