Quick Start — CrossPoint Matrix Switchers

Installation

Step 1

Mount the switcher in a rack.

Step 2

Turn off power to the input and output devices, and remove the power cords from them.

Step 3

Cable the switcher for RGBHV, RGBS, RGsB, RsGsBs, component video , S-video, or composite video input and output (3). See page 2-3 in this manual for details.

Step 4

Cable the switcher for stereo audio input (HVA models). Each input has a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input (4). Connectors are included with each switcher, but you must supply the audio cable. High impedance is generally over 800 ohms.

Step 5

Cable the switcher for stereo audio output (HVA models). Each output has a 3.5 mm, 5-pole captive screw connector that outputs the selected unamplified, line level audio. Connect an audio device, such as an audio amplifier or powered speakers (5).

The following terms are used throughout this manual:

Tie — An input-to-output connection.

Set of ties — An input tied to two or more outputs. (An output can never be tied to multiple inputs.)

Configuration — One or more ties or sets of ties.

Current configuration — The currently active configuration (also called configuration 0).

Preset — A configuration that has been stored. One preset can be assigned to each input button. When a preset is retrieved from memory, it becomes the current configuration.
