UHF 1 0 RECEIVER
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.

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 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

4. Connecting the Audio Output
The UHF 10 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.)

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 UHF-10 receiver clock-
wise 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.

headworn or lavalier microphone or the UH-10 handheld microphone
transmitter)
3. The microphone is now ready to use. The A and/ or B DIVERSITY LED
INDICATORS (2) on the UHF 10 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 UHF
10 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.]
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.
15
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.

13
The UHF 10 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 distor-
tion may result.

1. Unscrew the BATTERY COMPARTMENT COVER (13) and remove,
exposing the BATTERY HOLDER (14). Insert a fresh 9V ALKALINE
BATTERY (15), 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 (16) to
the STANDBY position (transmitter on, audio muted) or the ON position
(transmitter and audio both on). The BATTERY INDICATOR LED (17) 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.

UB-1 0 BO DYPACK TRAN SMITTER
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.
(Note: The INPUT LEVEL CONTROL (27) is deactivated and not used when
the UB-10 is in INSTRUMENT mode. Levels should be adjusted with the
volume control of your instrument.)
2. The UB-10 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.)/ HEADWORN MIC/ LAVALIER MIC.
The AF PEAK LED INDICATOR (3) on the UHF 10 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 noticeable distortion may result.
3. The UB-10 is provided with a 3.5 mm LOCKING JACK (21) for connect-
ing the audio input selected. Connect either the INSTRUMENT CORD (22)
or the HEADWORN MIC (23) 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 clock wise to thread
it on the jack. To unplug, reverse the process. Slip the transmitter into a
pocket or CLIP (28) it on to your clothes or instrument strap (if using the
UB-10 as an instrument transmitter). The CLIP can be rotated 900 if the
transmitter is to be attached horizontally (instead of vertically) by
loosening the screw holding the clip.
(Note: Scratchy noises can sometimes occur when some electric guitars
with dirty pots or connections are used with any wireless system. There
fore, 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 or headworn microphone)
Secure the connection from the LAVALIER (24) or HEADWORN MIC
CORD (23) 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
headworn 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.
4. Turn on the UB-10 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 UHF 10 receiver should now be lit, indicating a received
signal from the transmitter.
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 UHF 10 receiver instruc-
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 UHF 10 receiver instructions.

tions. [Note: Observe care in selecting P.A. volume, transmitter location
and speaker placement so that acoustic feedback (howling and screech-
ing) 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].

20
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, experi-
ment and set for maximum possible gain without audible distortion on
the high level peaks. (Note: Turning down the gain too much can com-
promise the signal-to-noise and is not recommended.)

The AF PEAK LED INDICATOR (3) on the UHF 10 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 CON-
TROL (27) on the UB-10 transmitter, or noticeable distortion may result.
