If the receiver’s volume control is set

too high, it may overdrive the input
of the attached audio mixer, causing
distortion. Conversely, if the output is set
too low, the overall signal-to-noise ratio
of the system may be reduced, causing
noticeable hiss. If such noise occurs,
adjust the output level of the receiver
so that highest sound pressure level
going into the microphone transmitter
causes no input overload in the mixer, but
permits the mixer level control to operate
in the normal range (not too high and
not too low). This provides the optimum
signal-to-noise for the entire system.

Do not use “general purpose” carbon
batteries. When batteries are weak,

For the best operation, the receiver

should be placed at least 3’ (1 m) above
the ground and 3’ (1 m) away from a wall
or metal surface. The transmitter should
also be at least 3’ (1 m) from the receiver.
Keep antennas away from noise sources
such as motors, automobiles, neon lights,
signal processors, computers, as well as
large metal objects.

in use. For longest life, remove the
batteries if the unit is not to be used for
a long period as the transmitters draw
a tiny residual current to maintain the
programmed settings, even when turned
off. Also, since batteries installed for a
long time can sometimes corrode and/or
leak, causing damage, it is generally
recommended that batteries be removed
whenever the transmitters are not
being used.

instrument use: Scratchy noises can
sometimes occur when an electric guitar
with dirty pots or connections is used with
a wireless system. Therefore, the supplied
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 noise, we suggest these steps to
eliminate problems:
1) Make sure all guitar volume and tone
pots are clean and all contacts are solid.
This is very important.
