10Output A connector — Connect an audio device, such as an amplifier or powered speakers, to these left and right RCA connectors.

11Output B connector — Connect an audio device, such as powered speakers, to this 3.5 mm, 5-pole captive screw connector for balanced or unbalanced audio output.

Figure 2-4 shows how to wire the captive screw audio connector. The connector is included with the switcher, but you must obtain the cable. Insert the wires into the appropriate openings in the captive screw connector. Tighten the screws on top to fasten the wires.

CAUTION

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

Do not tin the wires!

Figure 2-4 — Wiring the audio output connector

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.

By default, the audio output follows the video switch.
