The Headphone system
The Headphone (earphone) system in the ARC-15 console is provided so that audio can be listened to while the microphone is active
and the monitor speakers are muted. The Headphone system receives the same audio feed as the Monitor system but does not mute
when the microphone channel is turned on. The Headphone system has a 1/4" headphone jack on the rear of the console. The head-
phone amplifier connected to the headphone jack is designed to work with high impedance and 8 ohm headphones.
CUE
The ARC-15 console features Autocue. Whenever a channel is placed into cue, the audio in the Headphone system will mute and the
Cue audio will play over the Program signal.
TALKBACK
When talkback logic is activated from another studio, then Auto-cue is activated, Headphone program audio is muted, and the audio
from the Talkback input is placed into the Headphone system for intercom.
MUTING
The headphone system is not muted. When the control room microphone is turned on, the Monitor system will mute (audio is turned
off) so that there will not be feedback from the speakers to the microphone. The headphone system can not have audio feedback so
muting is not required.

1) AIR- this is usually an off air audio feed to monitor the actual transmitted signal
2) PGM- the main Program output bus from the console
