Note: CTs 8200 is shown. Some CTs 4200 features are in different locations.

K. AC Power Cord Connector

Standard IEC type 320 inlet.

120V models: 15-amp.

220-240V models: 10-amp. Voltage is indicated above IEC inlet.

L. Output Connectors

One four-pole terminal strip for every two chan- nels with touch-proof cover. Accepts up to 10 AWG terminal forks. To connect outputs, first remove the touch-proof cover plate covering the terminal strip by removing the screw which holds it in place.

M. Accessory Panel

CTs 4200: Accepts an optional IQ-MC4A or VCA-MC4A module.

CTs 8200: Accepts an optional IQ-MC8 or VCA-MC8 module (explained in Section 5.3.1, Control Modules).

N. Channel Level Controls

One 21-position detented rotary potentiometer per channel, ranging from infinity (-70 dB) to

0 dB attenuation. Refer to Section 5.2.4 for pre- cise dB attenuation increments for each detent.

O. Input Connectors

Removable Phoenix-style barrier connectors for balanced input.

P. Mode Switch

Used on each consecutive pair of channels, this four-position switch is used to select the ampli- fier’s mode of operation: Dual 8/4 ohms,

Dual 70V, Bridge-Mono 16/8 ohms, and Bridge-Mono 100V.

IMPORTANT: Be sure to power off the amplifier before change the Mode- switch setting. If this is not done, the Bridge light will flash to indicate that the power must be cycled off and back on to reset the mode.

Q. Cooling Vents

Front-to-rear forced airflow.

CTs 4200, CTs 8200 specifications

Crown Audio is recognized as a leader in professional amplification, renowned for producing power amplifiers that offer exceptional sound quality and reliability. Among their esteemed offerings, the CTs 4200 and CTs 8200 have emerged as powerful solutions for various audio applications, particularly in fixed installations and live sound reinforcement.

The Crown CTs 4200 is a versatile 4-channel power amplifier designed to deliver reliable performance in a compact form factor. It features an output power of 4200 watts at 4 ohms, making it suitable for driving multiple speaker configurations. One of the key technologies employed in the CTs 4200 is the Class D amplifier design, which ensures high efficiency while minimizing heat generation. This efficiency not only results in cleaner audio reproduction but also allows for a lighter and more portable product ideal for venue installations.

Equipped with the latest DSP (Digital Signal Processing) technology, the CTs 4200 offers comprehensive control over audio signals. Users can take advantage of features like EQ adjustments, crossover settings, and limiter controls, allowing for precise tuning to match specific acoustic environments. The front panel provides an intuitive interface for gaining access to these settings, while LED indicators provide real-time feedback on the amplifier's status.

The CTs 8200, on the other hand, elevates the output capabilities to new heights. With 8200 watts of output power at 4 ohms, this amplifier is designed for more extensive setups requiring greater amplification. It maintains the same Class D efficiency as its counterpart while offering additional channels for enhanced flexibility in setup configurations.

Both amplifiers feature a rugged construction designed to withstand the rigors of touring and installation environments, with reliable connectors and durable chassis. They also include comprehensive protection circuitry to safeguard against overloads and overheating, ensuring longevity and consistent performance.

Connectivity options further enhance their usability, providing XLR and TRS inputs along with Speakon outputs, making them compatible with a wide range of professional audio equipment. Their compatibility with Crown's intellectual property for network control opens up opportunities for remote monitoring and operation, simplifying integration into larger audio systems.

In summary, the Crown Audio CTs 4200 and CTs 8200 power amplifiers stand out for their exceptional output power, advanced DSP features, efficient Class D technology, and robust construction. Whether utilized for permanent installations or in dynamic live sound applications, these amplifiers offer unparalleled performance and versatility, solidifying Crown's legacy in professional audio amplification.
