When making connections for the switcher from existing audio cables, see figure 2-9. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring and sleeve.

The audio level for each input can be individually set, via RS-232 link, to ensure that the level on the output does not vary from input to input. See chapter 3, Operation, and chapter 4, Remote Control, for details.

83.5 mm, 5-pole captive screw connectors — Connect balanced and/or unbalanced stereo audio outputs to these sockets using connectors which are included with each MMX SVA switcher (you must supply the audio cable). See figure 2-11 for an illustration on how to wire a connector for the appropriate output type.

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

9RCA audio connectors — Connect unbalanced stereo audio outputs to these RCA connectors. See figure 2-10 for an illustration on how to wire the RCA connector.

By default, the audio output follows the video switch. Audio breakaway, commanded via the RS-232 link, allows the user to select from any one of the audio input sources. See chapter 4, Remote Control for details on the RS-232 connection.
