The Headphone system
The Headphone (earphone) system in the ARC-8 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 1/8" headphone jack on the rear of the console. The head-
phone amplifier connected to the headphone jack is designed to work with high impedance (not 8 ohm) headphones.
CUE
The ARC-8 console features Autocue. Whenever a channel is placed into cue, the Program audio in the Headphone system will dim and
the Cue audio will play over the Program signal.
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.
MONITOR SELECTOR SWITCH
This switch selects the audio source for the Monitor/Headphone system. Push the switch down (LED will light) to select an external
input to the monitor speakers and headphones. This is usually an off-air source so that the final output of the station can be moni-
tored. When the switch is up (unlighted) the Program bus output of the console is being monitored.
HEADPHONE VOLUME FADER
Sets the headphone level to the internal headphone amplifier.
