(Note: Scratchy noises can sometimes occur
when some electric guitars with dirty pots or
connections are used with any wireless system.
Therefore, the supplied INSTRUMENT CORD (17)
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) A 47pf capacitor soldered across the hot
to ground terminals of the guitar’s volume
and tone pots will provide extra filtering.)
7. Microphone use (with either a lavalier
or headworn microphone): Secure the
connection from the LAVALIER (18) or
HEADWORN MIC CORD (19) 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 (21) to the either
“STANDBY or ON” position.
Adjust the volume of the receiver as per
the Connecting the Audio Output above
DKW-8U receiver instruction.
[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 as lavalieres, 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].
8. For optimum performance, an INPUT
LEVEL CONTROL (23) is provided. Adjust the
gain by turning the control with a small
screw driver. For lavalier mic use, it is
recommended that the level be set at about
1/2 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 it is not
recommended.)
9. The DKW-8U receiver is equipped
with an AF LED DISPLAY (8). The LED
lights whenever an audio signal is being
transmitted from the transmitter.
(Note: The AF LED Display is not a peak level
indicator so it can light continuously during
audio signal input to the transmitter.)
