1 Welcome

Building on the foundation of the Com-Tech®Series, Crown’s CTs Series offers new flexibility and value for installed sound applications. The Com-Tech Series were the first to offer inde- pendent selection of high- and low-impedance operation for a specific channel, and CTs Series amplifiers continue that tradition, with power levels and features carefully chosen to perfectly integrate into fixed install design requirements.

Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed.

In addition, CTs Series amplifiers include a number of features which require some expla- nation before they can be used to their maxi- mum advantage.

Please take the time to study this manual so that you can obtain the best possible service from your amplifier.

1.1 Features

New Crown® Switching Power Supply for reduced weight.

High power-density, with eight channels in a 3U chassis and four channels in a 2U chassis.

Selectable constant-voltage (70V/100V) or low-impedance (8/4 ohm) operation for each channel pair.

FIT (Fault Isolation Topology) circuitry isolates faults within affected channels.

35 Hz High-Pass Filter (70 Hz in CTs 4200) is automatically inserted when the channel pair is set for constant-voltage operation. (corner frequency may be changed as a service option).

Accepts new MC accessory modules that tailor the amplifier to suit specific applica-

tions. Modules available for remote VCA level control and IQ System® Control.

Comprehensive array of indicators includ- ing Power and Data, along with Bridge, Ready, Signal, Clip, Thermal and Fault for each channel, provide accurate diagnos- tics.

Blue Power Indicator flashes if the ampli- fier shuts off due to an under-/over-voltage condition on the AC mains.

Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheat- ing, under-/over-voltage, high-frequency overloads and internal faults.

Proven Crown AB+B Multi-Mode®output topology.

Continuously-variable-speed fans opti- mize cooling efficiency.

Three Year, No-Fault, Fully-Transferable Warranty completely protects your invest- ment and guarantees its specifications.

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.
