BUZZING OR HUMMING NOISE IN SOUND SYSTEM.
þ There is nothing wrong with the T27 Transmitter. One or more
pieces of equipment in the sound system are being disturbed
by RF (Radio Frequency) signals produced by the T27. 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 the following steps:
þ Move the Transmitter away from the other sound equipment.
þ Make sensitive equipment more immune to RFI/EMI. The
manufacturers of your audio equipment may offer applica-
tion notes for this purpose. Williams Sound offers a docu-
ment giving suggestions for improving RF immunity in
existing audio equipment. (Technical Bulletin: Buzz Or Hum
In The Sound System, FRM 531) Unless you have the neces-
sary technical skills, this is best left to a qualified electronics
repair technician.
