Zone Amplification - Russound MCA Series Installation Manual

Fixed and Variable Line Level Outputs
All zones have line level outputs which can be used for additional amplification
when needed, such as for outdoor zones or larger rooms. The Zone Line Output
can be set to Variable (default) or Fixed (Always On).
NOTE: When the Line out connections are set at Fixed, the zone audio signal
is always on. Zones 7 and 8 do not have dedicated amplification and must use
the line level outputs. Russound recommends dedicated amplifiers for outdoor
areas or large rooms where more power is needed. The Russound D250LS is
perfect for such applications.

Common 12VDC Trigger Output
The Com 12VDC 100mA Out can be used to trigger additional amplification
when needed. This output supplies 12VDC 100mA when any one zone is
turned on. As long as at least one zone is on, the output will remain active
while turning additional zones on/off. The output will become inactive once all
zones of the controller are turned off. This output is per controller. In a multi-
controller scenario you will need to use the output of the controller that the
amplifier is being connected to for its particular zone.
