The auxiliary console primarily provides intercom facilities. In addition a VU meter with
selector and attenuator, a turntable volume control with studio playback switch, and a spare attenuator
also are provided.
a. The VU meter may be used to monitor other functions when the master console unit is in use.
b. The turntable volume control and studio playback switch provide a means of introducing
background material into the program material. For example, when an actor "on camera" appears to be
thinking of something having a direct bearing on the plot or program, the thoughts (previously tape
recorded) can be played through the studio speaker. Additionally, the actor is able to coordinate actions
and facial expressions properly by listening to the played-back material.
c. The intercom facilities provided by the auxiliary console are controlled by the six telephone
ring-down circuits, which may be connected to outside points. An additional intercom is necessary to
provide talkback facilities to the projection room, studio, announce booth, and order wire. The intercom
system should include a microphone, a preamplifier, and relay control key-type switches. The keys
should be located near the director's operating position.
