RGB output connections for MLC 506/506MA/506SA
5
Component video (YUV) output
— Connect a cable from these three BNC
connectors to the projector for component output.
6
Composite video (Video) and S-video outputs
— Connect a cable from the
top BNC connector for composite video output to the projector. Connect a
cable from the lower two BNC connectors to the projector for S-video output.
Audio output connections
7
Mono Amplified Output (MLS 506MA only)
— Cable speakers to this
output for 30 watt amplified mono audio output. This output provides a
mono signal even if the input is a stereo signal. The Audio Out captive screw
connectors (
11
) can output stereo audio.
Follow the appropriate Mono Amplified Output wiring diagram for the type
of load you want
to use: 4 ohm,
8 ohm, or a
distributed 70 volt
or 100 volt
(depending on the
model) system.
The 70 volt model
is shown here; the
wiring is the same
for both versions
of the MLS 506MA.
