2. Increase the input signal level from the sound
system by turning up a mixer control.
3. Make sure a valid narrow-band channel is
selected and make sure the transmitter and
receivers are tuned to the same channel.
Buzzing or humming noise in sound system.
1. Most likely, there is nothing wrong with the
T20 transmitter. One or more pieces of
equipment in the sound system are being
disturbed by RF (Radio Frequency) signals
produced by the T20. The most likely suspects
are your amplifier, mixer, or tape deck. The
RF gets into the other equipment primarily
through the power cord, speaker wires, or
unshielded inputs, all of which can act as
antennas.
Try moving the “RF Power” switch to the
–6dB or –12dB position. This will reduce the
system range somewhat.
2. If remedy 1 does not solve the problem, we
recommend using the optional Coax Antenna
(ANT 005), which should be located 15-20
feet away from the other sound equipment.
You may add additional RG-59 feedline as
needed.
4. If changing to the Coax Antenna doesn’t help,
it’s time to dig deeper into the problem. This
involves a slight modification to the equipment
causing the problem. Unless you have the
necessary technical skills, this is best left to a
qualified electronics repair technician. Call
your Authorized Dealer or Williams Sound
Corporation for more information. Ask for the
Buzz Paper.
