(MLS 406 Series)

video
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.

Display outputs — Connect cables from the
appropriate port(s) on the projector or display
panel to these BNC connectors according to the
output signal type, as shown below.
