Applications & Configurations
To make any configuration changes, the top of the VCM-88C must be removed. Be sure
to disconnect all cables & power before opening the unit. Jumper settings are illustrated in
the table & diagrams below.
Single Connector Insert
To use a mixing console’s single jack insert capabilities with the VCM-88C, an internal
jumper must be selected to properly configure the input and output connections. Once
configured the input is on the tip and the output is on the ring of the In jack. The Out jack
is not used.
Single Channel Pass-Through
When Using Master Output for personal monitor mixing or other application, it is possible
to pass a channel’s input directly to it’s output jack, eliminating the need for extra “Y”
cables when daisy-chaining. The VCA circuit’s output signal is still summed to the Master
Output, but is removed from the channel output jack.
Input/Output Matrixing
Input Matrixing means that an input can be internally routed to one or more additional
channel inputs, particularly useful in distributed zone applications. Each of the matrixed
VCA channels share a common input signal but retain their distinct level controls via the
RD-8C, RW-8C, or other hardware or software controllers.
