The audio level for each input can be individually set, via the front panel or RS-232/422, to ensure that the level on the output does not vary from input to input. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5, Matrix Software for details.

CAUTION

Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

By default, the audio output follows the video switch. Audio breakaway, commanded via the front panel, under RS-232/422 control, or Windows- based control program, allows you to select from any one of the audio input sources. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5, Matrix Software for details.

See chapter 4, Programmer’s Guide, for definitions of the SIS commands and chapter 5, Matrix Software for details on how to install and use the control software.

The CrossPoint Series Matrix Switchers are factory configured for RS-232 control. To use the switcher under RS-422 control, an internal cable must be moved. See Appendix B for the procedure for shifting the cable.
