Mute Control
Each priority bus (High, Medium, and Low) can be externally activated. This allows priority buses of two or more Power Vector units to be linked together for system expansion purposes. A particular mute priority can be externally forced by shorting that priority’s bus terminal to the C terminal of the Mute Control (the C terminal is the system ground). Forcing the H priority bus this way will mute all modules except for modules set for priority level 1 (highest priority). Forcing the M priority bus will mute modules set for priority levels 3 or 4, but not levels 1 or 2, and forcing the L priority bus will only mute modules set at priority level 4. See section on Bridging and illustration on page 8.
Bridging
This connector makes the PowerVector’s mix bus available externally and allows the connecting of Power Vector units for system expansion and simple room combining.

System Expansion of Power Vector Amplifiers
Using the bridging RCA connector, it is possible to connect two or more Power Vector amplifiers. It is not recommended that more than three amplifiers be bridged together due to bridging loss.When connecting mute control functions, make certain that the wiring is consistent (H to H, M to M, and so forth). See illustration below.
