5 Advanced Features and Options

5.3 Options

Below are some available options. For current options, visit the Crown website at www.crownau- dio.com.

5.3.1 Control Modules

IQ-MC (IQ Module): See Figure 5.3. A single IQ- MC module provides IQ control and monitoring capability 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, Ther- mal and Fault error reporting, Load Supervision, output limiting, Listen Bus, AUX control port,10 presets, and real-time “read-only” software indica- tion of amplifier hardware indicator, level control, and mode switch status.

VCA-MC (VCA module): See Figure 5.4. 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, 4-channel amplifiers use two connec- tors; 8-channel amplifiers use four connectors.

Wall-Mount level control panels for use with VCA module:

1-VCAP:See Figure 5.5. Used in conjunction with

aVCA-MC module, this is a single-gang panel pro- viding remote volume control for one or more CTs amplifier channels. The potentiometer on the panel is wired directly to one of the VCA connectors on the VCA-MC.

4-VCAP:See Figure 5.6 This is a two-gang panel providing remote volume control for four or more CTs amplifier channels. The potentiometers on the panel are wired directly to the respective VCA con- nector on the VCA-MC.

Refer to the VCA-MC Operation Manual for wiring of the single or multiple channel level control.

Your amplifier may have come with an IQ-MC or 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. Contact Crown Technical Support for more details.

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 chart below to select the correct accessory for your requirements.
