URR-1 0 RECEIVER
1. Rackmounting the Receiver
The URR-10 is supplied with RACK EARS (17) which can be attached with the
screws provided on the front of the side panels to enable rackmounting the
receiver. (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 URR-10.
Always ensure adequate air flow and heat dissipation in any rack configuration.)
2. Powering the Receiver
24
Plug the 12V AC/ DC ADAPTER (15) provided into the DC INPUT JACK (11) 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 (8)
once to turn on the receiver. The POWER ON LED (7) will now light and the
receiver is operational.
34
26
3. Antennas
The URR-10 is supplied with two detachable ANTENNAS (16). These can be either
rear-mounted (standard) on the BNC ANTENNA JACKS PROVIDED (9) or mounted
on the front (when rackmounting the receiver) with the optional FR-2 FRONT-
ANTENNA RACKMOUNT KIT (18). To use the FR-2 kit, attach these special rack
ears to the front of the side panels of the receiver, as with the standard rack ears
provided. Attach the two short cables supplied between each ANTENNA JACK (9)
and the jacks on the back of the FR-2 RACK EARS (18). This will provide a
connection between the FR-2 front-panel antenna jacks and the antenna jacks of
the receiver. Connect the antennas to either these FR-2 jacks or the antenna jacks
on the back of the receiver directly if not using the optional FR-2. Extend the
TELESCOPIC ANTENNAS (16) fully to obtain maximum range. Optimal antenna
position is 45 degrees from the receiver (at 90 degrees from each other).
25
24
4. Squelch Adjustment
In normal operation, the SQUELCH CONTROL (2) should be set fully clockwise to
the factory preset RF level ”10”. 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 (3) and/ or one or more LEDs
of the 5 LED RF LEVEL (4) display flicker or stay on, the squelch control should be
turned counterclockwise until the 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 re-establish the radio link.

5. Connecting the Audio Output
For optimum performance, an INPUT LEVEL CONTROL (32) is provided. Adjust
the gain by turning the control with your thumb. For lavalier mic use, it is recom
mended 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 URR-10 receiver provides both a fixed mic level BALANCED AUDIO OUTPUT
XLR (14) and an adjustable line level UNBALANCED AUDIO OUTPUT 1/ 4" JACK
(13). The level from the UNBALANCED OUTPUT is controlled by the front panel
VOLUME CONTROL (6) and the rear panel LEVEL LOW/ HI SWITCH (12). This
switch adjusts the maximum volume of the level range controlled by the VOLUME
CONTROL. In the “LOW” position, the level of the signal from the UNBALANCED
OUTPUT, with the VOLUME CONTROL set to “10”, is about 10% of the maximum
volume available with the “HI” position. Proper use of the LOW/ HI SWITCH
enables better control of the UNBALANCED OUTPUT volume.
The AF LEVEL DISPLAY (5) on the URR-10 receiver will light up to 5 LED indicators
for all input signals. Occasional flickering on and off during use of the top red LED
is normal, but if the red LED stays lit continuously, turn down the INPUT LEVEL
CONTROL (33) on the UB-10 transmitter or noticeable distortion may result.
(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 UB-10 in the “instrument” setting)
Insert an audio cord with a 1/ 4" mono phone plug in the UNBALANCED OUTPUT
JACK (13) on the rear panel of the receiver. Plug the other end of the cord into an
amplifier, effects, or mixing board. With the LEVEL LOW/ HI SWITCH (12) set to
HI, adjust the VOLUME CONTROL (6) on the URR-10 receiver clockwise to about
3/ 4 rotation, 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 “10” will provide 4dB gain over a cord.
33
31
Microphone Connection (using the UB-10 transmitter with either a headworn or
lavalier microphone or the UH-10 handheld microphone transmitter)
For microphone use, either the BALANCED MIC AUDIO OUTPUT XLR (14) or the
1/ 4" line level UNBALANCED OUTPUT (13) 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 jack 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 connec-
tions. For your convenience, the XLR output level is preset at the factory and is not
adjustable with the receiver volume control.

24
To use the 1/ 4" UNBALANCED OUTPUT JACK (13), follow the instructions for the
Instrument Connection (above), except start with the LEVEL LOW/ HI SWITCH set to
LOW and the receiver volume at 1/ 2 MAX and adjust both the switch and the
volume control until the volume level is optimal. If the volume control is set too
high, you may overload your mixer or amp.
29
The URR-10 receiver is equipped with an AF LEVEL LED DISPLAY (5) which
indicates the level of the received audio from the transmitter. There are 4 green
and 1 red LED in this display and in normal operation they will go on and off with
the changing signal level. If the top (red) LED stays on continuously, decrease the
volume to the transmitter or overload distortion may result.

11
The AF LEVEL LED DISPLAY (5) on the URR-10 receiver will light up to 5 LEDs for
all input signals. Occasional flickering on and off during use of the top red LED
indicator in this display is normal, however if the red LED stays on continuously,
turn down the instrument volume or the INPUT LEVEL CONTROL (33) on the UB-10
transmitter, or noticeable distortion may result.
FRONT PANEL
(Note: Scratchy noises can sometimes occur when some electric guitars with dirty
pots or connections are used with any wireless system. For this reason, the
supplied INSTRUMENT CORD (28) 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) Provide extra filtering with a 47pf capacitor soldered across the hot to ground
terminals of the guitar’s volume and tone pots.)

6. Microphone Use (with either a lavalier or headworn microphone)
Secure the connection from the LAVALIER (30) or HEADWORN MIC CORD (29) 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. When ready to
speak, slide the OFF/ STANDBY/ ON SWITCH (31) to the ON position. Adjust the
volume of the receiver as per the Audio Output Microphone Connection section of
the above URR-10 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 a 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].

1. Slide open the hinged BATTERY COMPARTMENT (24) and insert a fresh 9V
ALKALINE BATTERY (25), 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.
1. Unscrew the BATTERY COMPARTMENT COVER (19) and remove, exposing the
BATTERY 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. The UB-10 is equipped with an INPUT SELECTOR SWITCH (26) 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.
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 UB-10 is provided with a 3.5 mm LOCKING JACK (27) for connecting the
audio input selected. Connect either the INSTRUMENT CORD (28) or the
HEADWORN MIC (29) or LAVALIER MIC CORD (30) 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 transmit-
ter into a pocket or use CLIP (34) to attach it to your clothes or instrument strap (if
using the UB-10 as an instrument transmitter).
3. The microphone is now ready to use. The A and/ or B DIVERSITY LED INDICA-
TORS (3) and most or all of the RF LEVEL DISPLAY LEDs (4) on the URR-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 URR-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.]
4. Turn on the UB-10 by sliding the OFF/ STANDBY/ ON SWITCH (31) to the
STANDBY position (transmitter on, audio muted) or the ON position (transmitter
and audio both on). The BATTERY INDICATOR LED (32) 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 INDICATORS (3) and most or all of the RF DISPLAY LEDs (4) on
the URR-10 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 (28) 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 (31) to the ON position. Adjust the volume of the receiver as per the
Audio Output Instrument Connections section of the above URR-10 receiver
instructions. For optimum performance, an INPUT LEVEL CONTROL (33) is
provided on the top panel of the UB-10. 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 high-gain 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 compro
mise 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).
