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).
Step 6
If desired, connect a control system or computer
to the Remote RS-232/RS-422 port (6).
Step 7
Plug the switcher, input devices, and output
devices into a grounded AC source, and turn on
the input and output devices.

Definitions
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.
