Audio input and output connections (audio/video models)

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

By default, the audio follows the video switch. Audio breakaway, which is commanded via the front panel, under RS-232 control via the SIS or Windows- based control program, or optional IR 501 control, allows you to select from any one of the audio input sources. For details, see chapter 3, “Operation”, and chapter 4, “Remote Operation”, and refer to the IR 501 Small Matrix IR Remote Control User’s Guide.

5Balanced or unbalanced audio input connections (captive screw audio connector [A] models only) — 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 AV captive screw connector switcher, but you must supply the audio cable. See figure 2-4 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 5 k ohms.

Figure 2-4 shows two methods of wiring the captive screw audio connectors for input and figure 2-6 shows two methods of wiring the connectors for output. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring, and sleeve. If you are wiring a captive screw connector from an existing unbalanced audio cable, the white insulated wire is typically the left channel (tip) and the red insulated wire is typically the right channel (sleeve). There is no reliable standard for existing balanced audio cables.

Figure 2-4 — Captive screw connector wiring for audio inputs

The length of exposed wires is critical. The ideal length is 3/16” (5 mm).

•If the stripped section of wire is longer than 3/16”, the exposed wires may touch, causing a short circuit between them.

•If the stripped section of wire is shorter than 3/16”, wires can be easily pulled out even if tightly fastened by the captive screws.

6RCA connector audio inputs (RCA audio connector [A RCA] models only) — Each input has a pair (left and right) of RCA connectors for unbalanced stereo audio input (figure 2-5).
