Stereo Audio Switching
IN2200RS has stereo audio-follow-video switching capability. When Input 1 or Input 2 is
selected manually or automatically, the IN2200RS switches the stereo audio signals in
conjunction with their corresponding video signals.
INPUT AND LOCAL MONITOR OUTPUT
Located next to the 15-pin HD female video input connectors are 3.5mm stereo female audio
input ports (one for each video input). The audio inputs are compatible with unbalanced line
level audio signals from a computer sound card, CD player, VCR, laser disc player or other
device that outputs a stereo line level audio signal.
Located next to the 15-pin HD female local video output connectors are 3.5mm stereo female
audio output ports. Inputs 1 & 2 each have a local audio output that provides an unbalanced line
level signal, identical to the input signal. This is a passive output (not buffered) designed to drive
a local device such as powered speakers or other line level compatible audio equipment. Both
local outputs are always active, even when an input is not currently selected.
The following cables are available to connect audio equipment to the stereo audio inputs and
local outputs. For more information, see the Cable Pin Outs Diagram below.
IN9106 (1) 3.5mm Stereo Mini Male to (1) 3.5mm Stereo Mini Male, 6’ long
IN9107 (1) 3.5mm Stereo Mini Male to (1) RCA Stereo Male, 6’ long
Note: The diagram above is for input cables and local output cables only. The main audio
output has a different pin configuration (see diagram on the following page).
MAIN AUDIO OUTPUT
Located just to the right of the main BNC outputs, the main audio output provides a buffered
audio signal from Input 1 or Input 2, depending on which input is currently selected. The main
audio output signal is line level and can be set for unbalanced (factory default) or balanced. See
the IN2200RS Internal Controls Section on the following page for information on setting the
unit for unbalanced or balanced output.
The IN2200RS main audio outputs require one 3.5mm Mini DIN connector for left audio, and a
separate connector for right audio. This is done to accommodate unbalanced or balanced audio
signals.
