VCA-MC4A
VCA-MC8
CTs MULTICHANNEL
AMPLIFIER ACCESSSORIES
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 chassis.
Thus, the 4-channel CTs 4200 uses two con-
nectors; the 8-channel CTs 8200 uses four
connectors.
Crown CTs 4200 and 8200 amplifiers can be
supplied with a VCA-MC module already fac-
tory-installed, or your choice of MC modules
can be easily added to the amplifier 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
amplifier channels. The potentiometer on the
panel is wired directly to one of the VCA con-
nectors on the VCA-MC.
The 4-VCAP is a two-gang panel providing
remote volume control for four or more CTs
amplifier channels. Each potentiometer on the
panel is wired directly to the respective VCA
connector on the VCA-MC.

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