1. Powering the Receiver

Plug the 12V AC/DC ADAPTER (12) provided into the DC INPUT JACK (6) on the back of the receiver. Then plug the power supply into an AC outlet. (Note: Any DC source with 300mA capability can also be used.) Press the POWER SWITCH (5) once to turn on the receiver. The POWER ON LED (1) will now light and the receiver is operational.

2. Antennas

Extend the TELESCOPIC ANTENNAS (4) fully to obtain maximum range. Optimal antenna position is 45 degrees from the receiver (at 90 degrees from each other).

3. Squelch Adjustment

In normal operation, the SQUELCH CONTROL (8) 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 (2) 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 or the RF LEVEL LED displays will only light when the system transmitter is turned on. Turning the squelch control too far counter clockwise 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 the A/B Diversity LEDs and the 5 LED RF LEVEL display extinguish, the transmitter is out of range for that given location, and the user should move closer to the receiver to reestablish the radio link.

4. Connecting the Audio Output

The receiver provides both a fixed mic level BALANCED MIC AUDIO OUTPUT XLR (11) 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.)

Instrument Connection (using the transmitter in the "Instrument" setting)

Insert an audio cord with a 1/4" mono phone plug in the AUX AUDIO OUTPUT JACK (10) on the rear panel of the receiver. Plug the other end of the cord into an amplifier, effects, or mixing board. Adjust the AUX VOLUME CONTROL (9) on the receiver clockwise to about 3/4 full, until the volume level is comfortable for your application. This setting is roughly equivalent to a direct instrument cord connection. Turning the volume up to MAX will provide 4dB gain over a cord.

For optimum performance, an INPUT LEVEL CONTROL (27) is provided. Adjust the gain by turning the control with your thumb. For lavalier mic use, it is recommended that the level be set at about 2/3 maximum. For headworn 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.)

The AF PEAK LED INDICATOR (3) on the receiver will light for all loud input signals. Occasional flickering on and off during use is normal, but if the LED stays lit continuously, turn down the INPUT LEVEL CONTROL (27) on the transmitter, or noticeable distortion may result.

The AF PEAK LED INDICATOR (3) on the receiver will light for all loud input signals. Occasional flickering on and off during use is normal, however if the LED stays on continuously, turn down the instrument volume or the INPUT LEVEL CONTROL (27) on the transmitter, or noticeable distortion may result.

(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 (22) 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 solid–this 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.)

6. Microphone Use (with either a lavalier microphone)

Secure the connection from the LAVALIER (24) 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. 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 OFF/STANDBY/ON SWITCH (25) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above receiver instructions.

[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 headworn models that are used close to the mouth].

Microphone Connection (using the transmitter with either a headworn or lavalier microphone or the handheld microphone transmitter)

For microphone use, either the BALANCED MIC AUDIO OUTPUT XLR (11) 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 receiver is equipped with an AF PEAK LED INDICATOR (3) which lights with a strong audio signal from the transmitter. Occasional flickering on loud inputs to the transmitter is normal. If the LED lights continuously, decrease the volume to the transmitter or overload distortion may result.

1. Unscrew the BATTERY COMPARTMENT COVER (19) and remove, exposing the BAT- TERY HOLDER (20). Insert a fresh 9V ALKALINE BATTERY (21), observing the correct polarity as marked, and screw the cover back on to the microphone. Make sure the cover is screwed on completely. A fresh alkaline battery can last up to 10 hours in use, but in order to ensure optimum performance, it is recommended that you replace the battery after every 7-8 hours of use.

2. Turn on the UH-10 by sliding the OFF/STANDBY/ON SWITCH (22) to the STANDBY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (23) 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 battery should be replaced with a fresh one. To preserve battery life, turn the transmitter off when not in use.

3. The microphone is now ready to use. The A and/or B DIVERSITY LED INDICATORS (2) on the receiver should now be lit, indicating a received signal from the transmitter. When ready to speak, slide the transmitter switch to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above receiver instructions.

[Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided.]

1. Slide open the hinged BATTERY COMPARTMENT (18) and insert a fresh 9V ALKALINE BATTERY (19), observing the correct polarity. A fresh alkaline battery can last up to 10 hours in use, but in order to ensure optimum performance, it is recommended that the battery be replaced after 7-8 hours of use.

2. The Bodypack Transmitter is equipped with an INPUT SELECTOR SWITCH (20) in the battery compartment for selecting the type of audio input you will be supplying to the transmitter. Select from the choice of three positions: INSTRUMENT (for guitar, bass, etc.)/ LAVALIER MIC.

3. The Bodypack Transmitter is provided with a 3.5 mm LOCKING JACK (21) for con- necting the audio input selected. Connect either the INSTRUMENT CORD (22) or LAVALIER MIC CORD (24) as desired, according to the input selected.

(Note: Use only the input audio source as per the input selected with the AUDIO INPUT SELECTOR SWITCH or the audio will not be optimal–a muddy or distorted sound may result.) To secure the connection, turn the slip ring on the plug clockwise to thread it on the jack. To unplug, reverse the process. Slip the transmitter into a pocket or use CLIP (28) to attach it to your clothes or instrument strap (if using as an instrument transmitter).

4. Turn on the Bodypack Transmitter by sliding the OFF/STANDBY/ON SWITCH (25) to the STANDBY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (26) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, the LED either will not go on at all or will stay on continuously, indicating that the battery should be replaced with a fresh one. To preserve battery life, turn the transmitter off when not in use. The transmitter is now ready to use. The A and/or B DIVERSITY LED INDICA- TORS (2) on the receiver should now be lit, indicating a received signal from the transmitter.

5. Instrument Use

Plug the 1/4" phone plug from the INSTRUMENT CORD (22) into the instrument. As the cord to the instrument also serves as the antenna, be sure to extend it fully for maximum range. Rolling up or shortening the cord may reduce the effective operating range. When ready to play, slide the audio OFF/STANDBY/ON SWITCH (25) to the ON position. Adjust the volume of the receiver as per the Audio Output Instrument Connections section of the above receiver instructions. For optimum performance, an INPUT LEVEL CONTROL (27) is provided on the top panel of the Bodypack transmittert. Adjust the gain by turning the control with your thumb. For instrument use, it is recommended that this control be turned to maximum gain. However, for ultra highgain instrument sources such as active bass pickups or even extra hot guitar pickups, turning the level down slightly will create a cleaner sound.

(Note: Turning down the input gain too much can compromise the signal-to-noise ratio and is not recommended. Set for the maximum possible gain and headroom without noticeable distortion on the high level peaks).
