OPERATION
XR-61 RECEIVER
38
1. Rackmounting the Receiver
The XR-61 receiver is supplied with RACK EARS (1) 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 XR-61/62. Always ensure adequate airflow and
heat dissipation in any rack configuration.)
44
2. Powering the Receiver
43
Plug the 12V AC/DC ADAPTER (2) provided into the DC INPUT JACK (3) on the back of the
receiver. Then plug the power supply into an AC outlet. (Note: Any 12V DC source with
400mA capability can also be used.) Press the POWER SWITCH (4) once to turn on the
receiver. The POWER ON LED (5) integrated into the switch will now light and the receiver
is operational.
41
36
3. Antennas
37
Connect the front panel TELESCOPIC ANTENNAS (5) or optional remote antennas to the
ANTENNA JACKS (6). Extend the antennas fully to obtain maximum range. Optimal
antenna position is 45 degrees from the receiver (at 90 degrees from each other). For max-
imum 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
40
42
45
39
4. Mute (Squelch) Adjustment
In normal operation, the MUTE CONTROL (7) should be set fully counterclockwise to the
factory preset minimum RF level. However, in areas of high RF activity, the mute (or
squelch, 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 (8) and/or one or more LEDs of the 5 LED RF LEVEL DISPLAY
(9) flicker or stay on, the squelch control should be turned clockwise until the LEDs extin-
guish. 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 clockwise will reduce the range, but yield a quieter mute (squelch) 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.

4. Microphone Operation
5. Connecting the Audio Output
a. Turn on The Link 2 by sliding the ON/STANDBY/OFF SWITCH (41) to the STANDBY
position (transmitter on, audio muted) or the ON position (transmitter and audio both on).
The LOW BATTERY INDICATOR LED (40) will give a single quick flash, indicating usable
battery strength. In case of dead or low battery, the indicator will either not go on at all or
stay on continuously, indicating a battery voltage below 7V. If this occurs, replace with
fresh 9V battery. Remember to turn the transmitter off when not in use.
The XR-61 receiver provides both a fixed mic level BALANCED AUDIO OUTPUT XLR (10)
and an adjustable line level UNBALANCED AUDIO OUTPUT 1/4” JACK (11). The level
from the UNBALANCED OUTPUT is controlled by the rear panel VOLUME CONTROL (12).
(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 dam-
age. Also make sure that the phantom power on the input of the mixer is turned OFF
before making connection to the receiver.)
b. The Link 2 is now ready to use. The A and/or B DIVERSITY LED INDICATORS (8) and
most or all of the RF DISPLAY LEDs (9) on the XR-61 receiver should now be lit, indicating
a received signal from the transmitter. When ready to speak, slide the transmitter switch to
the ON position and adjust the volume of the receiver as per the Audio Output
Microphone Connection section of the above XR-61 receiver instructions. The AF LEVEL LED
DISPLAY (13) on the XR-61 receiver will light up to 5 LEDs (4 green and 1 red) 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, it means
the signal is too loud and there is the possibility of overload distortion. Re-position the
microphone farther from the source or adjust the Link 2 transmitter gain with the VOLUME
LO/HI GAIN SWITCH (39). Set for the maximum possible level without noticeable distortion
on the high level peaks. Set the GAIN SWITCH to LO to decrease the audio level, and set
the GAIN SWITCH to HI to increase the audio level. The red LED indicator should flicker
only on the loudest inputs.
a. Instrument Connection (using the WGT-15 instrument transmitter)
Insert an audio cord with a 1/4” mono phone plug in the UNBALANCED OUTPUT
JACK (11) on the rear panel of the receiver. Plug the other end of the cord into an
amplifier, effects, or mixing board. Adjust the VOLUME CONTROL (12) on the XR-61
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 maximum will provide 4dB gain over a cord.
b. Microphone Connection (using the WLT-15 transmitter with either a headset or
lavalier microphone or the WHT-15 handheld microphone transmitter)
For microphone use, either the BALANCED MIC AUDIO OUTPUT XLR (10) or the 1/4”
line level UNBALANCED OUTPUT (11) 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. (Note: 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 (11),
follow the instructions for the Instrument Connection (above), except start with the
receiver volume at 1/2 MAX and adjust the volume control until the volume level is
optimal. If the volume control is set too high, you may overload your mixer or amp.
[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 observe
the pickup patterns 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 mics that are used close to the mouth.]
(Note: Microphone elements can easily be destroyed by the buildup of salts and minerals
from perspiration and saliva. It is good practice to put a windscreen on the mic element at
all times to protect it.)

WGT-15 INSTRUMENT BODYPACK TRANSMITTER
1. Snap open the BATTERY COMPARTMENT (30) and insert a fresh 9V BATTERY (31),
observing the correct polarity. Close the compartment. The WGT-15 is provided with a
3.5 mm LOCKING JACK (32) for connecting the INSTRUMENT CABLE (35). To secure the
connection, turn the metal slip ring on the plug clockwise to thread it on to the jack. To
unplug, reverse the process. Slip the transmitter into a pocket or clip on to your clothes or
instrument strap. (Note: 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 effec-
tive operating range.)
2. Turn on the WGT-15 by sliding the OFF/STANDBY/ON SWITCH (32) to the STANDBY
position (transmitter on, audio muted) or the ON position (transmitter and audio both on).
The BATTERY INDICATOR LED (33) 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.
3. The WGT-15 transmitter is now ready to use. The A and/or B DIVERSITY LED INDICA-
TORS (8) and most or all of the RF DISPLAY LEDs (9) on the XR-61 receiver should now be
lit, indicating a received signal from the transmitter. Adjust the volume of the receiver as per
the Audio Output Instrument Connections section of the above XR-61 receiver instructions.
For optimum performance, an INPUT LEVEL CONTROL (34) is provided on the top panel of
the WGT-15. Adjust the gain by turning the control with a small slot head screwdriver. 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.
20

(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).

The AF LEVEL LED DISPLAY (13) on the XR-61 receiver will light up to 5 LEDs (4 green and
1 red) 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 adjust the INPUT LEVEL CONTROL (34) on the WGT-15 transmit-
ter, or noticeable distortion may result.
17
19
(Note: Scratchy noises can sometimes occur when some electric guitars/basses with dirty
pots or connections are used with any wireless system. For this reason, the supplied
INSTRUMENT CORD (35) 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 220 pF capacitor soldered across the hot to ground
terminals of the guitar’s volume and tone pots.)

observing the correct polarity. Close the compartment.
2. The WLT-15 is provided with a 3.5 mm LOCKING JACK (24) for connecting the micro-
phone. Plug in either the LAVALIER/LAPEL (25) or the HEADWORN MICROPHONE (26), as
supplied. To secure the connection, turn the metal slip ring on the plug clockwise to thread
it on to the jack. To unplug, reverse the process. Slip the transmitter into a pocket or clip
on to your clothes. To use the lavalier mic, attach it at chest level. Do not place 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 mic boom so that the mic is about one inch to the side
of the front of the mouth. (Note: The lavalier or headworn mic wire is also the transmit
antenna, and rolling up or shortening the wire may reduce the effective operating range.
Extend the wire fully during use, and keep it as straight as possible.)
