The Telephone Input Module
OFF-LINE ASSIGNMENT SWITCH
This switch will connect the control room mic to the caller and feed the caller to the
console cue system. The caller will be automatically removed from the Pgm, Aud, and
Utlk buses so he will not be on air. This allows the caller and the console operator to
speak ‘off-line’.
CHANNEL ON AND OFF
To turn a channel on, simply push the red ON switch at the bottom of the fader. When
the channel is on, the switch will be lighted. To turn the channel off, simply push the
yellow OFF button.
CHANNEL ON AND OFF LOGIC (Hybrid control)
The phone channel provides momentary, relay isolated logic to pick up the caller line
(start) and to release the phone line (stop)
OUTPUT BUS ASSIGNMENT
The green PGM and AUD and UTL buttons above the slide fader assign the channel to
any (or all) of the main audio mixing buses: Program & Audition & Utility. Push the but-
ton once to light the button and assign it to the bus. Push the lighted button again to
unassign the channel from the bus.
HYBRID AUDIO FEED
The output to the phone hybrid that the caller will hear is determined by the module’s
output bus assignments. The caller will hear a mix of all three output assignments. To
eliminate feedback, the output to the phone hybrid will NOT include the phone callers
voice. This is call mix-minus.
CUE
Cue will switch the caller into the cue system for listening to him without him being
on air.
To activate cue, click on the yellow CUE button above the fader. To exit the cue mode,
click on the CUE button again.
Cue audio will be heard in the speaker in the VU meter housing and in the Headphones.
Cue logic automatically switches the Headphones from the selected audio source to
the cue audio bus whenever any channel is placed into cue.
TWO PHONE MODULES
The mainframe supports either one or two phone modules. Each requires its own
hybrid. The audio feed to the hybrid includes the audio from the OTHER phone module.
