System 4 with One System 8/10 PLUS Switcher
The System 8/10 PLUS must be configured as a System 4 Slave. Connect the
RGBHV and Audio output of the System 8/10 switcher to the last (4th) input of
the System 4. Use the figure below as an example.
The System 4 will control the System 8/10 PLUS Switcher through the secondary
RS-232 port, by way of a System 4 Slave Adapter described in the System 4
User’s Manual.
Important audio
information! If balanced
audio connections are
made from the System 8/
10 PLUS audio output to the
System 4 audio input,
there will be +6 dB of gain.
This gain can be offset with
a 6 dB pad. If the level of
gain does not exceed the
System 4 maximum input
level, the level can be
offset with the System 4
audio gain/cut menu.
However, if audio
connections are made
unbalanced, there is
no gain.
The audio
attenuator(s) on the
System 8/10 PLUS
audio inputs should be
set to 0 dB cut by
turning the attenuator
clockwise until it stops.
This will set all input
audio levels on the
System 4. Refer to the
System 4 User Manual
for audio setup.
