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-5200 specifications

The Classe Audio CA-5200 is a high-performance power amplifier that exemplifies the pinnacle of audio engineering. Designed to deliver exceptional sound quality and robust power, the CA-5200 is a favorite among audiophiles and home theater enthusiasts alike.

One of the standout features of the CA-5200 is its impressive power output. With a five-channel configuration, it provides an astounding 200 watts per channel into 8 ohms, delivering superior dynamics and headroom. This makes it an ideal choice for driving a wide range of loudspeakers, from compact, bookshelf models to larger, floor-standing options. The amplifier can effortlessly handle the demands of both music and multichannel movie soundtracks, ensuring that every nuance is captured with fidelity.

The CA-5200 utilizes Class A/B amplification technology, which is renowned for its efficiency and warmth. This technology combines the benefits of Class A operation—characterized by low distortion and an open soundstage—with the efficiency of Class B operation. The result is a powerful amplifier that remains cooler in operation while still providing rich, detailed sound reproduction across the frequency spectrum.

Another essential feature of the CA-5200 is its advanced circuitry and build quality. The use of high-grade components throughout, including custom power transformers and large filter capacitors, ensures that the amplifier can handle transient peaks and demanding listening sessions without strain. The resulting sound is clear and dynamic, with an emphasis on accuracy and naturalness, catering to the most discerning listening tastes.

Classe Audio also integrates their proprietary AutoBias technology into the CA-5200, which automatically adjusts the bias settings of the output transistors for optimal performance under various load conditions. This feature ensures consistent sound quality, regardless of the dynamics of the material being played or the impedance of the connected speakers.

In terms of connectivity, the CA-5200 offers multiple input options, allowing for seamless integration into a variety of audio systems. The amplifier’s front panel is carefully designed, featuring easy-to-read indicators and user-friendly controls, making it simple to operate even in a complex setup.

Overall, the Classe Audio CA-5200 stands out as a powerful and versatile amplifier that marries technology with craftsmanship. Whether used in a dedicated two-channel audiophile setup or as part of an immersive home theater experience, the CA-5200 delivers the sonic performance that captivates and engages music and movie lovers alike.
