RGBHV input and output

The switcher can connect to up to as many as 16 RGBHV video and/or stereo audio devices, depending on the model. The switcher can output to as many as 16 video and/or audio outputs, depending on the model.

The CrossPoint Series switchers can also switch RGBS, RGsB, RsGsBs, component video, S-video, or composite video by using four, three, two, or one BNC(s).

If switching a video format other than RGBHV, ensure that the same video planes (R, G, B, H/HV, and/or V) are used on the switcher output as on the input.

The switchers do not alter the video signal in any way. The signal output by the switcher is in the same format as the input.

On the 8 x 16, 16 x 8, 12 x 12, and 16 x 16 matrix sizes, the connectors for each video plane are grouped together (all of the red inputs grouped together, all of the green inputs grouped, and so on). Ensure that you connect the input of each video plane to the corresponding connector in the correct group (see the drawing at right).

Audio input and output (HVA models only)

By default, the audio ties follow the video ties. Audio breakaway, which can be activated via the front panel or under RS-232/RS-422 control, allows you to select from any one of the audio input sources and route it separately from its corresponding video source. See chapter 3, “Operation”, chapter 4, “Programmer’s Guide”, and chapter 5, “Matrix Software” for details.

3Connections for balanced and unbalanced audio inputs — Each input has a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each switcher, but you must supply the audio cable. See figure 2-3 to wire a connector for the appropriate input type. Use the supplied tie-wrap to strap the audio cable to the extended tail of the connector. High impedance is generally over 800 ohms.

CAUTION

CAUTION

The length of the exposed (stripped) portion of the copper wires is important. The ideal length is 3/16" (5 mm). Longer bare wires can short together. Shorter bare wires are not as secure in the direct insertion connectors and could be pulled out.

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 output circuits. Ensure that the connector is plugged fully and only into the desired input or output.
