The Intercom Explained
A Clearcom compatible interface is built into the
console. This industry standard intercom system
provides two way talk and signal communication so
that technicians and stage crew can communicate
during set up and performance. It uses a three wire
connection such as a microphone cable. The
intercom interfaces with the talkback mic and
console headphones system. This avoids the
difficulty faced by operators in checking problem
sources such as radio mics in the console
headphones while communicating with stage crew
via a separate intercom headset.
It is useful to be able to turn off the intercom audio
while checking console signals and to reduce
unwanted background audio while running the
show. A large yellow lamp in the meterpod lights to
attract the attention of the operator when the
intercom is being signalled, especially useful if
LISTEN is turned off.
The controls are logically grouped near the talkback
section for easy single handed operation of the
listen, signal and talk functions.
