PRELIMINARY

 

The output signal is in the same format (RGBHV, RGBS, RGsB, RsGsBs,

 

S-video, or composite video) as the input signal. The signal is switched,

 

but not processed. Cables can be connected between the projector and

 

one, some, or all of the switcher’s video outputs.

H

Monitor Output — This 15-pin HD connector serves as either a local

 

monitor loop-through port or an additional RGB output. Connect a cable

 

between this port and the local or additional display device.

 

There are three different options (modes) for determining which input

 

signal, if any, is sent to the monitor output. These modes are selectable

 

only via RS‑232 control. For an explanation of modes and video routing,

 

see pages 3-7 and 3-8. See chapter 4, Serial Communication for details

 

on selecting the mode.

Audio outputs

Lineout audio output and Preamp audio output — These outputs are simultaneously active and can be wired and configured for balanced or unbalanced mono or stereo audio signal output. The switcher must also be configured for the corresponding signal type (mono or stereo).

Selecting either mono or stereo (via RS-232 by way of the control software or SIS commands) selects the output signal format for both the Lineout and Preamp outputs. The switcher configuration (mono or stereo) and the output wiring must match.

•The Lineout connector outputs a fixed, line level audio signal that is not affected by front panel Volume knob adjustments. A recording or assistive listening device would typically be connected here.
