Opening Battery Compartment
WGT-15 Instrument Bodypack Transmitter
1. Snap open the BATTERY COMPARTMENT (25) and insert a fresh 9V BATTERY
(26), observing the correct polarity. Close the compartment. The WGT-15 is provided with
a 3.5 mm LOCKING JACK (27) for connecting the INSTRUMENT CABLE (28). 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-15 by sliding the OFF/STANDBY/ON SWITCH (29) to the STAND-
BY position (transmitter on, audio muted) or the ON position (transmitter and audio both
on). The BATTERY INDICATOR LED (30) 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 TX DISPLAY LEDs (5) on the 401
receiver should now be lit, indicating a received signal from the transmitter. Adjust the vol-
ume of the receiver as per the Audio Output Instrument Connections section of the above
401 receiver instructions. For optimum performance, an INPUT LEVEL CONTROL (31)
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.
(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 (9) on the 401 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 (31) on the WGT-15
transmitter or noticeable distortion may result.
(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 (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 produce 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 termi-
nals of the guitar’s volume and tone pots.)
