Troubleshooting

In general, you should refer any service problems to your Classé dealer. Before contacting your dealer, however, please check to see if the problem is listed here.

1.No sound, and no Channel LED is lit.

•The amplifier is not plugged into the AC mains, or the AC mains are down (circuit breaker, fuse).

•A brown-out or short-term loss of power might require the internal microprocessor to be reset. Unplug the unit for at least 30 seconds and then plug it in again and try powering it up.

•The AC mains fuse is blown. See Troubleshooting #4, below (or contact your Classé dealer).

•The AC mains is out of range. Check the voltage specified on the rear panel.

2.No sound, and one or more Channel LEDs is blinking red.

•Your protection circuitry may have been engaged. To reset the amplifier, press and hold the Standby button for 3 seconds to power down the amplifier. Then disconnect all inputs and outputs.

•Then try powering up the amplifier by pressing the Standby button. If the LED continues to blink, there is a fault condition in the amplifier itself. It should be powered down, disconnected from the AC mains and taken to your Classe dealer for service.

•If it powers up without any difficulty, power it back down and reconnect only the inputs. Then restart the amplifier. If it goes into its blinking protection mode, something is wrong with a component “upstream” of the amplifier—probably a DC offset or similar problem. Your amplifier is trying to protect your loudspeakers (even small amounts of DC can damage woofers in relatively little time). Try different source components to discover whether the problem is limited to a single source, or exists all the time (which would indicate a problem with the preamplifier). Contact your dealer for help with the appropriate component.

3.The amplifier keeps shutting off.

•Make sure you are providing adequate ventilation to the amplifier, and that the ambient room temperature is below 105°F (40°C).

•Run through the troubleshooting sequence outlined above (assuming the amplifier is going into its protection mode).

CA-3200 specifications

The Classe Audio CA-3200 is a high-performance power amplifier designed for audio enthusiasts seeking exceptional sound quality and robust power. It exemplifies Classe's commitment to precision engineering and sophisticated technology, making it a standout component in any high-fidelity audio system.

The CA-3200 boasts a powerful output of 200 Watts per channel into 8 ohms, and it doubles that to 400 Watts into 4 ohms, ensuring ample power to drive a wide range of loudspeakers with authority and detail. This amplifier employs a Class AB design, which combines the best attributes of Class A and Class B amplification. The result is a warm, rich sound that maintains clarity and dynamics, even at high volume levels.

One of the unique features of the CA-3200 is its high-quality, low-noise power supply. This power supply includes an oversized transformer and large storage capacitors, providing the necessary reserves for transient peaks. This design minimizes noise and ensures that the amplifier delivers clean power without distortion, whether during soft passages or explosive musical moments.

Classe has implemented a custom-designed output stage that utilizes fully complementary circuitry. This innovation helps to eliminate crossover distortion, resulting in an accurate reproduction of the audio signal. Additionally, the CA-3200 features advanced thermal management technology, including extensive heat-sinking and forced-air cooling. This ensures that the amplifier remains cool and reliable during extended use, even in demanding environments.

The architectural design of the CA-3200 matches its performance capabilities. The chassis is constructed from high-quality materials, providing both aesthetic appeal and structural integrity. The front panel features visually expressive meters that allow users to monitor power levels easily, while the rear panel provides balanced and unbalanced input options, increasing flexibility in setups.

Furthermore, the CA-3200 is designed for easy integration into existing systems, offering a variety of control options, including trigger inputs and RS-232 connectivity for automation and remote control purposes.

In summary, the Classe Audio CA-3200 is an exemplary power amplifier that combines significant power output, advanced technologies, and meticulous craftsmanship. Its ability to deliver pristine audio performance while offering versatility makes it a compelling choice for both audiophiles and casual listeners alike, ensuring that it meets the demands of modern audio systems with ease.
