ACS 4.1 Installation and Operation Manual
OVERVIEW
Product Overview
The ACS 4.1 provides matrix audio switching of 4 stereo inputs to one stereo out-
put. Matrix switching allows any/or all inputs to be assigned to one output. The ACS
4.1 has eight GPI inputs that may be used for remote control operation or as PIP trig-
gers, four open collector channel status outputs, and a built-in silence sensor with a
dedicated open collector status output. The ACS 4.1 may be controlled via front
panel switches, contact closures, logic and/or the multi-drop RS-232 serial port
(control via USB or Ethernet with optional devices). Installation is simplified with
plug-in euroblock screw terminals.
