IQ-MC4 & IQ-MC8
SmartAmp Automation for CTs Multichannel Amplifiers
The Crown IQ-MC4 and IQ-MC8 are optional IQ control modules for
the Crown CTs multichannel power amplifiers. The IQ-MC4 is the IQ
module for the CTs 4200, and the IQ-MC8 is the IQ module for the
CTs 8200. The modules require an IQ System with an IQ2-compati-
ble interface.
A single IQ-MC module provides IQ control and monitoring capabili-
ty to all channels of the amplifier. Features include basic IQ amplifier
control and monitoring, including attenuation, mute, polarity, input
level, output level, power supply temperature, and thermal level
meters. Advanced features include IOC, Thermal and Fault error
reporting, Load Supervision, output limiting, Listen Bus, AUX control
port, 10 presets, and real-time “read-only” software indication of
amplifier hardware indicator, level control, and mode switch status.
Crown CTs 4200 and 8200 amplifiers can be supplied with an IQ-
MC module already factory-installed, or your choice of MC modules
can be easily added to the amplifier by any authorized Crown
Service Center.

VCA-MC4 & VCA-MC8
Remote Level Control
The Crown VCA-MC4 and
VCA-MC8 are optional level-
control modules for the Crown
CTs multichannel power
amplifiers. The VCA-MC4 is
for the CTs 4200, and the
VCA-MC8 is for the CTs
8200. A VCA-MC module pro-
vides 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 chan-
nels. 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.
Features
• 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.
• Optional wall-mount level control panels for use with
VCA modules: 1-VCAP and 4-VCAP.
