Home Theater Triggers
These triggers are used to integrate with home theater systems that can
provide a 12 volt trigger. The MCA-C5 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 conguration diagram on the
next page for connections.
