Product Description

The Broadcast Tools® SS 4.4 provides matrix audio switching of 4 stereo inputs to 4 stereo outputs. Matrix switching allows any/or all inputs to be assigned to any/or all outputs. The SS 4.4 may be controlled via front panel switches, contact closures, open collectors, logic and/or the multi-drop RS-232 serial port (USB or Ethernet optional). Installation is simplified with plug-in euroblock screw terminals.
