Extron electronic CrossPoint 128, CrossPoint 88, CrossPoint 168 Video input and output connections

Video input and output connections

All video input and output connections to the CrossPoint switchers are made with female BNC connectors. Some types of video output devices do not have BNC video output connectors. For these cases, a suitable cable or connector adapter is necessary between the device output connector and the BNC input connector of the CrossPoint.

RGBHV video inputs — Connect RGBHV video inputs to these BNC connectors for each input.

RGBHV video outputs — Connect RGBHV video outputs to these BNC connectors for each output.

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. 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 CrossPoint Series Matrix Switchers do not alter the video signal in any way. The signal output by the switcher is in the same format as the input.

Audio input and output connections (HVA models only)

CAUTION

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. Exercise care to ensure the captive screw connector is plugged into the desired input or output.

4Connections for balanced and unbalanced audio inputs — Each input has a

3.5mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included

with each CrossPoint switcher, but you must supply the audio cable. See figure 2-3 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

When making connections for the CrossPoint Series Switcher from existing audio cables, see figure 2-4. 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 2-3 and figure 2-5.
