Russound MCA-88X Installation Manual
Home Theater Triggers
These triggers are used to integrate with home theater systems that utilize
a 12VDC trigger. The MCA-88X can be used to power manage sources that
are being shared with the home theater system. For example, the power
management system will check to see the state of the home theater before
powering down source gear. Refer to the sample configuration diagram on the
next page for connections.
IN
This 12VDC Trigger input will have different functionality based on the state
of the system and the state of the trigger. The connections for the trigger are
made using a two-conductor cable with 3.5mm male mini-plug. The tip is
positive (+) and the sleeve is negative (-).
"System Off" (all zones have been off for at least 5 minutes): If 12VDC is applied
to this input, it will activate the power management ON command to the
sources. While all zones are still OFF and 12VDC is removed, the system will
wait 5 minutes and then activate the power management OFF command to
the sources.
"System On" (at least one zone is on): If 12VDC is present but all zones get
turned OFF, the power management OFF commands will not be sent until 5
minutes after the 12VDC is removed from the trigger.
Note:
If the trigger is not being used, power management will operate
normally.
HOME THEATER TRIGGERS
OUT
The 12VDC trigger out can be used to engage any 12VDC trigger device or
component such as the Russound D850 Amplifier. The connections for the
trigger out are made using a two-conductor cable with 3.5mm male mini-plug
ports at each end. The tip is positive (+) and the sleeve is negative (-).
The output is a pass-through of the Home Theater trigger input. It can be used
to activate additional devices whenever the Home Theater trigger is active.
