The Crown VCA-MC4A and VCA-MC8 are optional
level-control modules for the Crown CTs multichannel
power amplifiers. 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 amplifier channels. Thus, the 4-channel
CTs 4200 uses two connectors; the 8-channel CTs
8200 uses four connectors. Crown CTs 4200 and
8200 amplifiers can be supplied with a VCA-MC
module already factory-installed, or your choice of
MC modules can be easily added to the amplifier
by any authorized Crown Service Center.
