Channel Selection in a Given Area and Simultaneous Use
of Multiple Channels.
Transmission by wireless microphones and low power audio transmitters may
encounter various interference problems. Interference may be caused by local
area TV or commercial broadcast institutions.
In addition, interference can be due to wireless receivers and transmitters used
simultaneously in close proximity to each other. Their fundamental or harmon-
ic frequencies can conflict with each other and cause interference problems;
noises, static, hiss, dropouts, squealing or totally inoperative.
The following clusters of channels have been designated that are compatible
to operate with each other simultaneously.
Note
When interference
problem is encountered,
verify that the
microphones are operating
on frequencies in the
same cluster.
If TV or other transmission
is interfering, change all
the wireless components
to another cluster.
