TP-170V Constant-Voltage
Transformer Panel
The Crown
®
TP-170V is a rack-mountable panel
with four autoformers to provide impedance
matching between amplifier outputs and “constant
voltage” loudspeakers. This unit allows amplifiers
without direct 70V or 100V output capability to
drive distributed speaker systems designed to
operate at those voltages. The TP-170V is con-
structed of sturdy steel, and hinged on one side to
allow easy access to the inside connections.

VCA-MC4A & VCA-MC8
FEATURES
Independent remote level control for each
channel.
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-
channel 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
To order accessory modules for your amplifier, please
refer to the model tag (located on the back panel of the
amplifier) for your amplifier’s specific model number.
Then refer to the information below to select the correct
accessory for your requirements.
CTs 4200: VCA-MC4 or IQ-MC4
CTs 4200A: VCA-MC4A or IQ-MC4A
CTs 8200 or CTs 8200A: VCA-MC8 or IQ-MC8

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 potenti-
ometer that provides remote volume control for
one or more CTs amplifier channels. The poten-
tiometer 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.

P.I.P.-CLP
Is designed to detect and prevent overload. The same error detecting circuit
that is used to signal the IOC indicator is used to activate this error-driven
compressor. It is not a typical signal-driven compressor but a circuit to pre-
vent an overload. It can yield up to 13 dB of additional signal safety margin
without noticeable program change.
