Audio input and output

By default, the audio ties follow the video ties. Audio breakaway, which can be activated via the optional front panel or under Ethernet or RS-232 control, allows you to select from any one of the audio input sources, regardless of video group, and route it separately from its corresponding video source. See the “Operation” section, the “Programming Guide” section, the “Matrix Software” section, and the “HTML Operation” section for details.

NOTE: Audio ties can be made only to outputs in the computer/audio subgroup (outputs 1 through 6).

Audio inputs (either input subgroup)

HConnections for balanced and unbalanced audio inputs — Each input has a 5-pole,

3.5 mm captive screw connector for balanced or unbalanced stereo or mono audio input. Connectors are included with each switcher, but you must supply the audio cable.

See figure 3 to wire a connector for the appropriate input type and impedance level. Use the supplied tie-wrap to strap the audio cable to the extended tail of the connector.

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

NOTES: • The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).

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

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

• Figure 4 identifies the tip, ring, and sleeve. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring and sleeve. The tip, ring, and sleeve wires are also shown on the captive screw audio connector diagrams (see figure 3, above, and figure 5 on the next page).

The audio level for each input can be individually set at the front panel or via Ethernet or RS-232 control to ensure that the level on the output does not vary from input to input. See the “Operation” section, the “Programming Guide” section, the “Matrix Software” section, and the “HTML Operation” section for details.
