The ACS-400 - Eight Channel Audio
The ACS-400 Manages Multi Channel Audio or Can Provide Extra Microphone
Preamplifier Channels...
The ACS-400 contains eight individual amplifiers. Each amplifier features line or microphone level input sensitivity,
VCA volume control, on/off, and dimming. Volume control can also be programmed so that one control can control the
gain of 2 or more channels in any grouping desired. For example, one control can be programmed to adjust six
channels for a 5.1 multi channel level control and another can adjust the remaining two channels for a stereo mix. The
ACS-400 was developed for the management of televeision master control multi channel monitor control but can be
used in virtually any application where remote control of volume, on/off and dimming is required. The ACS-400 also
can be configured for microphone level input in situations where additional microphone preamplification is needed in
a radio, television or professional sound environment.
The ACS-400 is available in two versions. Pictured above is the ACS-100-1 standard front panel which contains eight
channel activity inicators, eight mute status indicators, a dim status indicator and a global mute indication. All
control of audio is done by remote control.The optional REM-400 panel is available from BDI which directly interfaces
to the ACS-400-1 via a single DB-25 male to female cable. If local control of audio is desired, the ACS-400-2 is
identical in function but is supplied with the REM-400 panel with individual channel volume controls along with on/
off control buttons is provided.See reverse for a photo and description of the versatile REM-400 panel.
