1-VCAP & 4-VCAP

`` FEATURES

•1-VCAP provides remote volume control for one or more CTs amplifier channels.

•Fits into a 1-gang electrical box.

•4-VCAP provides remote volume control for four or more CTs amplifier 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 amplifier 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

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.

CTs4200: VCA-MC4 or IQ-MC4

CTs 4200A: VCA-MC4A or IQ-MC4A

CTs 8200 or CTs 8200A: VCA-MC8 or IQ-MC8

T-170V Constant-Voltage

Transformer

The Crown T-170Vis 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

TP-170V Constant-Voltage

Transformer Panel

The Crown® TP-170Vis 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.
