2-3CrossPoint Plus Matrix Switchers • Installation
Video input and output connections
All video input and output connections to the CrossPoint Plus 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 Plus.

RGBHV video inputs — Connect RGBHV video inputs to these BNC
connectors for each input.
3
RGBHV video outputs — Connect RGBHV video outputs to these BNC
connectors for each output.
The CrossPoint Plus 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 Plus 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.

Connections 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 CrossPoint Plus 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.

Figure 2-3 — Captive screw connector wiring for inputs
When making connections for the CrossPoint Plus 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.
The audio level for each input can be individually set, via the front panel or
RS-232/422, to ensure that the level on the output does not vary from input to
input. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5,
Matrix Software, for details.
