1-VCAP & 4-VCAP
FEATURES
• 1-VCAP provides remote volume control for one
or more CTs amplifi er channels.
• Fits into a 1-gang electrical box.
• 4-VCAP provides remote volume control for
four or more CTs amplifi er channels.
• Fits into a 2-gang electrical box.
Wall-Mount Controllers
Crown VCAP panels are wall-mounted panels
with potentiometers that provide remote control
of the volume of Crown CTs amplifier channels
via a VCA-MC4 or VCA-MC8 module installed in
the amplifier. Two models are available: 1-VCAP
and 4-VCAP.
1-VCAP: Used in conjunction with a VCA-MC
module, this is a 1-gang panel with one poten-
tiometer that provides remote volume control
for one or more CTs amplifier channels. The
potentiometer on the panel is wired directly
to the VCA connectors on the VCA-MC.
4-VCAP: This is a 2-gang panel with four poten-
tiometers 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.
VCA-MC4A & VCA-MC8
FEATURES
• Independent remote level control for each chan-
nel.
• 4-pin removable Phoenix-style barrier con-
nectors provide the +10VDC control voltage,
ground, and control lines for two amplifi er
channels.
• Optional wall-mount level control panels for use
with VCA modules: 1-VCAP and 4-VCAP.
Remote Level Control
The Crown VCA-MC4A and VCA-MC8 are optional
level-control modules for the Crown CTs multi-chan-
nel 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.
Choosing the Right Module

T-170V Constant-Voltage
Transformer
The Crown T-170V is a single
autoformer that provides imped-
ance matching between an ampli-
fier output and "constant voltage"
loudspeakers. It allows amplifiers
without direct 70V or 100V out-
put capability to drive distributed speaker systems
designed to operate at those voltages.

TP-170V Constant-Voltage
Transformer Panel
The Crown ® TP-170V is a rack-mountable panel
with four autoformers to provide impedance match-
ing between amplifier outputs and "constant volt-
age" loudspeakers. This unit allows amplifiers with-
out direct 70V or 100V output capability to drive
distributed speaker systems designed to operate
at those voltages. The TP-170V is constructed of
sturdy steel, and hinged on one side to allow easy
access to the inside connections.
