ENCORE DUET RECEIVER
1. Rackmounting the Receiver
There are 2 options available for rackmounting the Encore DUET receiver: singly or
side-by-side with another Encore Series receiver.
a. Single mounting: Remove the receiver SIDE MOUNT CLIP (1) from each side of
the receiver (as shown) and slide in the optional ERM-12 RACK EARS (9).
b. Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (1) from
both Encore receivers, join the two receivers with the EJC-2 JOINING CLIP
(10) and attach the ERM-22 RACK EARS (12) as shown. (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 Encore DUET. Always
ensure adequateairflow and heat dissipation in any rack configuration.)
38
44
2. Powering the Receiver
43
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 12V DC source with 400mA 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.
36
37
41
39
3. Antennas
The Encore DUET receiver is supplied with TELESCOPIC ANTENNAS (16), one each
for Channel A and Channel B. These should be extended fully to obtain maximum
range. Optimal antenna position is 45 degrees from the receiver (at 90 degrees
from each other). For maximum 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
4. Mute (Squelch) Adjustment
XLR Connector – Connects microphone to the transmitter module for signal input
Locking Ring – Locks microphone to the transmitter
Optional Pouch – For lavalier bodypack operation (with beltclip and strap ring
for securing)
36
In normal operation, the MUTE CONTROLS (2) for each channel (A & B) should be
set fully counterclockwise to the factory preset minimum RF level. However, in areas
of high RF activity, the mutes (or squelches, as they are sometimes called) may need
to be adjusted to compensate for the adverse conditions in a particular location. If,
with the transmitter off, one or more LEDs of the receiver's 5 LED RF LEVEL DISPLAYS
(4) for that channel transmitter flicker or stay on, the squelch control for that channel
should be turned clockwise until the LEDs extinguish. When the squelch is properly
adjusted, the RF LEVEL LED displays will only light when that channel transmitter is
turned on. Turning the squelch control too far clockwise will reduce the range, but
yield a quieter mute (squelch) function. When the 5 LED RF LEVEL display extinguish-
es, the transmitter for that channel 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
4. Microphone Operation
The Encore DUET receiver provides both a fixed mic level BALANCED AUDIO OUT-
PUT XLR (14) for each channel and an adjustable line level A + B UNBALANCED
AUDIO OUTPUT 1/4" JACK (13) which provides a mixed (summed) Ch A plus Ch B
output signal. The mixed level from the A + B UNBALANCED OUTPUT is controlled
by the rear panel VOLUME CONTROLS (6) for each channel. (Note: As when mak-
ing 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. Also make sure that the phantom power on the input of the mixer is
turned OFF before making connection to the receiver.)
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 bat-
tery voltage below 7V. If this occurs, replace with fresh 9V battery. Remember to
turn the transmitter off when not in use.
b. The Link 2 is now ready to use. Most or all of the RF DISPLAY LEDs (4) on that
channel of the Encore DUET receiver should now be lit, indicating a received
signal from that transmitter. When ready to speak, slide the transmitter switch
to the ON position and adjust the volume of that channel of the receiver as per
the Audio Output Microphone Connection section of the above Encore DUET
receiver instructions. The appropriate AF LEVEL LED DISPLAY (5) on the Encore
DUET 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 instrument transmitter)
Insert an audio cord with a 1/4" mono phone plug in the A + B
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. Adjust the
appropriate VOLUME CONTROL (6) for the channel being used on the Encore
DUET receiver clockwise to about 3/4 rotation, until the mixed 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. (Note: Since this a mixed output of Ch A & Ch B,
both channels with be processed simultaneously by the amplifier and/or
effects connected to, which may not be appropriate for your application.
b. Microphone Connection (using the WLT transmitter with either a headset or
lavalier microphone or the WHT handheld microphone transmitter)
For microphone use, either the BALANCED MIC AUDIO OUTPUT XLRs (14)
or the 1/4" line level A + B 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 either or both of the XLR OUTPUT JACKS 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.)
(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 micro-
phone 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 head-
worn mics that are used close to the mouth.)
For your convenience, the XLR output levels are preset at the factory and are
not adjustable with the receiver volume controls. To use the 1/4" A + B
UNBALANCED OUTPUT JACK (13), follow the instructions for the
Instrument Connection(above), except start with the receiver volume at 1/2
MAX and adjust the volume control for each channel until the mixed Ch A &
Ch B volume level is optimal. If the volume controls are set too high, you may
overload your mixer or amp.
(Note: Microphone elements can easily be destroyed by the buildup of
salts and minerals from perspiration and saliva. It is good practice to put

33
32
2. Turn on the WHT by sliding the OFF/STANDBY/ON SWITCH (20) to the STAND-
BY position (transmitter on, audio muted) or the ON position (transmitter
and audio both on). The BATTERY INDICATOR LED (21) 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.
30
3. The microphone is now ready to use. Most or all of the RF LEVEL DISPLAY
LEDs (4) on the Encore Duet 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 Encore Duet receiver instructions. The AF LEVEL
LED DISPLAY (5) on the Encore Duet 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. Back
off from the microphone until the red LED indicator only flickers on peaks.
[Note: Observe care in selecting P.A. volume, transmitter location and speaker
placement so that acoustic feedback (howling or screeching) will be avoided.]
[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 wind-
screen on the mic element at all times to protect it.]

WGT 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 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 effective operating range.)
2. Turn on the WGT by sliding the OFF/STANDBY/ON SWITCH (32) to the STAND-
BY 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, indicat-
ing 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 transmitter is now ready to use. Most or all of the RF DISPLAY LEDs (4)
on the Encore Duet 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 Encore Duet receiver instructions. For optimum per-
formance, an INPUT LEVEL CONTROL (34) is provided on the top panel of the WGT.
Adjust the gain by turning the control with a small slot head screwdriver.
21
20
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 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 (5) on the Encore Duet 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 transmitter, or noticeable distortion may result.
18
(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 capaci-
tor 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:
19
17
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.)

2. The WLT is provided with a 3.5 mm LOCKING JACK (24) for connecting the
microphone. Plug in either the LAVALIER/LAPEL (25) or the HEADWORN MICRO-
PHONE (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.)
22
25
3. Turn on the WLT by sliding the OFF/STANDBY/ON SWITCH (27) to the STANDBY
position (transmitter on, audio muted) or the ON position (transmitter and audio both
on). The BATTERY INDICATOR LED (28) will give a single quick flash, indicating us-
able 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.

4. The microphone is now ready to use. Most or all of the RF DISPLAY LEDs (4) on
the Encore Duet 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 Encore Duet receiver instructions. The AF LEVEL LED
DISPLAY (5) on the Encore Duet 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 AUDIO INPUT
LEVEL CONTROL (29) until the red LED indicator flickers only on the loudest inputs.
(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: omnidi-
rectional mics pick up sound equally from all directions and are prone to feed-
back 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 acous-
tic gain and thus are also more prone to feedback than close-source mics such
