The Telephone Input Channel
The ARC-15 supports a single phone caller for Live On Air or Off-line (contest caller, etc.) applications on channel 15 of the console.
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 red ON button again.
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)
PROGRAM AND AUDITION BUS ASSIGNMENT
The green PGM and AUD buttons above the slide fader assign the channel to either (or both) of the main audio mixing buses: Program
& Audition. Push the button 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 channel ten's output bus assignments: Pgm only, Aud only, or
a mix of Pgm & Aud. The output to the phone hybrid will NOT include the phone callers voice which eliminates feedback.
TALKING TO THE CALLER (off line)
Push the red 'TALK TO CALLER' button to feed the control room mic to the caller. When the button is down, the program audio fed to
the caller is muted and only the control room mic audio is heard. The button is a momentary operation. Push down to talk, release the
button to return the caller to the normal bus audio.
LISTENING TO THE CALLER (off line)
To listen to the caller before airing (or during a talkback conversation), place the phone channel ten into cue by clicking on the CUE
button.
