FUNCTION DESCRIPTION
Front Panel:
The ACS 8.2 is a 1-rack unit device (19”w x 1.75”h x 10”d). The front panel sup-
ports fourteen selection switches, 23 LED indicators, headphone selection switch,
headphone jack and headphone level control.
Rear Panel:
Installation is simplified with pluggable screw terminals. The rear panel hosts audio
and control pluggable screw terminals, input/output trimmer controls, multi-drop
RS-232 modular connector and 7-pin DIN power supply connector.
Switches:
The front panel of the ACS 8.2 contains selection pushbuttons for each input chan-
nel. A mute switch is provided to turn off each audio channel, while the enable
switch may be configured as a safety switch. Fade up, down and dim push buttons
are provided for inputs assigned to output one. A push-push switch is furnished for
headphone monitoring of the two output channels. Input channels may be pro-
grammed for the following operations:
• Overlap - Overlap one audio source with another while the button for the sec-
ond source is held down. Both channels will be fed to the output until the sec-
ond button is released, at which time the first audio source will be switched off.
• Mix - May connect more than one input at a time to any given output - Push once
to connect input, again to disconnect.
• Interlock - Connecting one input to any output disconnects all other inputs from
that output.
