Audio input and output connections (audio models only)

The captive screw connector can easily be inadvertently plugged partially into one receptacle and partially into an adjacent receptacle. This misconnection could damage the audio output circuits. Ensure that the captive screw connector is plugged into the desired input or output.

4Audio input connections

MAV 128 RCA — Each input has a pair (left and right) of RCA connectors.

MAV 168/1616 — Each input has a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are

included with each MAV Series switcher, but you must supply the audio cable. See figure 2-6 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

When making connections for the MAV Series Switcher from existing audio cables, see figure 2-7. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring and sleeve. The ring, tip, and sleeve wires are also shown on the captive screw audio connector diagrams, figure 2-6 and figure 2-8.

The audio level for each input can be individually set, via the front panel or RS-232/RS-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.
