Audio output connections

Audio output connections

The switcher have two 3.5mm 5-pole captive screw audio output ports.

The Fixed port delivers a fixed volume, stereo balanced/unbalanced audio output.

The Variable port delivers a variable volume, stereo balanced/unbalanced audio output. The volume range is 0 (-84 dB) through 100 (0 dB). The default volume setting is 100 (0 dB). Volume is controllable only via the RS-232 port.

NA balanced audio output provides a +6 dB gain. An unbalanced audio output provides a 0 dB gain.

Remote control connection

An RS-232 serial control port at the right edge of the rear panel is used for computer or infrared (IR) remote control of the device. The switcher’s firmware can be upgraded through the RS-232 port. See chapter 3, “Operation and Control”.

The RS-232 port communications protocols are: 9600 baud, 8 data bits, 1 stop bit, no parity, and no flow control.

IR remote control requires use of the IR 102 Remote Control Kit (part #70-224-01)

For computer or infrared remote control, only pins 2 (transmit data), 3 (receive data), and 5 (ground) are required. Disconnect all other conductors in the attachment cable for proper operation.
