and Indicators

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

A. Bridge Mode Indicator

Yellow LED, one per channel pair, illumi- nates when the channel pair's Mode Switch is set to the “Bridge” position. If Mode switch is changed while amplifier is powered up, Bridge LED will flash, indicat- ing that the amplifier must be powered off and on to reset the Mode. See Section 6.9.

B. Ready Indicator

Green LED, one per channel, illuminates when the channel is initialized and ready to produce audio output.

C.Signal Indicator

Green LED, one per channel, illuminates to indicate the presence of input signals above –40 dBu.

D.Clip Indicator

Red LED, one per channel, illuminates when the THD of the channel’s output sig- nal rises to a level typically considered as the onset of audible clipping. The Clip Indicator also will illuminate during Ther- mal Level Control (TLC) or input overload.

E.Thermal Indicator

Red LED, one per channel, flashes when the channel has shut down due to thermal stress or overload. If the power supply goes into thermal overload, all channel LEDs will flash.

Figure 4.1 CTs 8200 front panel.

F.Fault Indicator

Red LED, one per channel, illuminates when the amplifier output channel has stopped operating.

G.Ventilation Grille Front-to-rear forced airflow.

H.Data Indicator

Yellow LED indicates IQ Loop data activity (if the amplifier is equipped with an IQ-MC module, and connected to an IQ Loop).

I.Power Indicator

Blue LED indicates amplifier has been turned on and AC power is available. Indi- cator also flashes if the amplifier shuts off due to an under/over-voltage condition on the AC mains.

J.Power Switch

Amplifier is on when the switch is in the IN position.

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.
