Mute Control
Each priority bus (High, Medium, and Low) can be externally activated.
This allows priority buses of two or more Power Vector products 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.
System Expansion of Power Vector Products
By interconnecting the Bridging Connector and Mute Control lines, it is possible to connect two or more
Power Vector units into a larger integrated system. Wire the bridging jack and mute control lines as shown in
the diagrams for bridging either 2 or 3 units together. The overall system gain of Power Vector products dimin-
ishes when they are bridged because each unit’s mix bus loads down the other product’s bus. When bridging
two Power Vector products, the system gain drops by about 6 dB. When bridging 3 Power Vector units together,
the system gain drops by approximately 12 dB. It is important to make sure that the input module or that the
input signal source itself has enough level to make up for the bridging loss otherwise the products may not be
able to reach their full rated output.

Note:
Bridging can be any combination of
Power Vector Mixers and/or Amplifiers.
Bridging more than 3 Power Vector units
together is not recommended because
of bridging losses.
