URR-10 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.

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

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.

source with 300mA capability can also be used.)

once to turn on the receiver. The POWER ON LED (7) will now light and the
receiver is operational.

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).

(Note: Do not mount the receiver in a rack directly above an amplifier or

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

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

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.

(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.

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 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" 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.

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 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.

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.

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.

(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 alldirections 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].
