The VCA-MC (VCA multichannel module) is an optional accessory module for the CTs 
4200 or CTs 8200 power amplifier. The module provides independent remote level control 
for each channel. VCA-MC4A (Figure 1.1) is the VCA module for the CTs 4200. VCA-
MC8 (Figure 1.2) is the VCA module for the CTs 8200.

Four-pin removable Phoenix-style barrier connectors provide the +10 VDC control voltage, 
ground, and control inputs for two amplifier channels. Thus, the 4-channel CTs 4200 uses 
two connectors; the 8-channel CTs 8200 uses four connectors. The control inputs are 
labeled VCA1 (for channel 1), VCA2 (for channel 2), and so on.

VCA-MC modules can be controlled in one of two ways:
•  Optional Crown 1-VCAP or 4-VCAP wall-mount level controls 
•  An external control voltage of 0 to 10 VDC

1-VCAP: See Figure 1.3. Used in conjunction with a VCA-MC module, this is a single-
gang panel with one potentiometer that provides remote volume control for one or more 
CTs amplifier channels. The potentiometer on the panel is wired directly to the VCA con-
nectors on the VCA-MC.

4-VCAP: See Figure 1.4. This is a two-gang panel with four potentiometers that provide 
remote volume control for four or more CTs amplifier channels. The potentiometers on the 
panel are wired directly to the VCA connectors on the VCA-MC.
