CTs Multi-Channel Power Amplifiers

4 Operation

4.1 Precautions

Your amplifier is protected from internal and external faults, but you should still take the fol- lowing precautions for optimum performance and safety:

1. Before use, your amplifier first must be con- figured for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties. For information on wiring and configuration, please consult the Setup section of this manual or, for advanced setup techniques, consult Crown’s Amplifier Application Guide available online at www.crownaudio.com.

2. Use care when making connections, select- ing signal sources and controlling the out- put level. The load you save may be your own!

3. Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.

4.WARNING: Never connect the output to a power supply, battery or power main. Electrical shock may result.

5.Tampering with the circuitry, or making unauthorized circuit changes may be hazard- ous and invalidates all agency listings, and may also void the product’s warranty.

6.Do not operate the amplifier with the red Clip LEDs constantly flashing.

7.Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and loudspeaker damage may result.

8.Use caution when operating the amplifier with a 2-ohm load impedance on 1 channel. Do not operate the amplifier with less than a 2-ohm load impedance per channel when driving more than 1 channel. Due to the amplifier’s output protection, such a config- uration may result in premature clipping, speaker damage or a blown power fuse.

Remember: Crown is not liable for damage that results from overdriving other system compo- nents.

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.
