CTs MULTICHANNEL
VCA-MC4A
VCA-MC8
he Crown® VCA-MC4A and VCA-MC8 are
optional level-control modules for the
Crown CTs multichannel power amplifi ers.
T
The VCA-MC4A is for the CTs 4200, and the
VCA-MC8 is for the CTs 8200.
A VCA-MC module provides independent
remote level control for each channel. 4-pin
removable Phoenix-style barrier connectors
provide the +10VDC control voltage, ground,
and control lines for two amplifi er chassis.
Thus, the 4-channel CTs 4200 uses two connectors; the 8-channel CTs 8200 uses four
connectors.
Crown CTs 4200 and 8200 amplifi ers can be
supplied with a VCA-MC module already factory-installed, or your choice of MC modules
can be easily added to the amplifi er by any
authorized Crown Service Center. Contact
Crown Technical Support for more details.
Also available are optional wall-mount level
control panels for use the the VCA module: the
1-VCAP and 4-VCAP.
The 1-VCAP is a single-gang panel providing
remote volume control for one or more CTs
amplifi er channels. The potentiometer on the
panel is wired directly to one of the VCA connectors on the VCA-MC.
The 4-VCAP is a two-gang panel providing
remote volume control for four or more CTs
amplifi er channels. Each potentiometer on the
panel is wired directly to the respective VCA
connector on the VCA-MC.

and VCA-MC8, contact Crown Technical Support at 800-342-6939 or 574-294-8200. Also,
