6 Troubleshooting

CONDITION: Power indicator is off.

POSSIBLE REASON

• The amplifier has lost AC power.

• The amplifier’s Power switch is off.

• The amplifier is not plugged into the power receptacle.

• The amplifier output level is so high that the power supply fuse has blown. Verify that input levels and output impedances are within safe ranges. Refer the unit to an authorized Crown service center for fuse replacement.

CONDITION: Power indicator is flashing.

POSSIBLE REASON:

• The AC line voltage has dropped below 10% or has risen above 10% of the nominal line voltage of the power supply.

Refer to section 5.1.6 for specific voltage requirements.

CONDITION: Fault indicator is on.

POSSIBLE REASON:

•The amplifier channel has stopped oper- ating. Return the unit to an authorized Crown Service Center.

CONDITION: Distorted sound.

POSSIBLE REASON:

•Load is wired incorrectly or Dual/Bridge mode switch is set incorrectly. Check both.

•Input is overloaded by a signal level that is too high. Turn down your amplifier level controls, or turn down the input sig- nal, until the clip light goes out.

•Thermal Level Control (TLC) is active.

Note: If the signal sounds distorted even though the Clip LED is off, the input signal is distorted. Check gain staging and output lev- els of the mixer or preamp.

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.
