SS 16.4 – Analog Stereo Matrix Switcher (Special Order)

Available by special order only. The SS 16.4 provides matrix audio switching of 16 stereo inputs to 4 stereo plus 4 monaural outputs. Matrix switching allows any or all inputs to be assigned to any or all of the 4 outputs. The SS 16.4 may be controlled via front panel switches, contact closures, 5-volt TTL/CMOS logic and/or the multi-drop RS-232 or RS-485 serial port. Installation is simplified with removable euro-block screw terminals.
