Why Classe Audio Amplifier blowing fuses?
If the fuses in your Classe Audio Amplifier are blowing, check for a short between the fuse and ground. Also, check the power supply circuits, specifically the positive rail, negative rail, and Mosfet supply.
What to do if Classe Audio CA-400 Amplifier turns into protection?
If your Classe Audio Amplifier is turning into protection mode, examine it for any smoked or burned components. Also, check the power supply circuits (positive rail, negative rail, and Mosfet supply), the source and load, the protection circuit itself, the sensor wires between the sensor PCB and control PCB, and the output transistors and Mosfet drivers.
Why Classe Audio CA-400 Amplifier has no output?
If your Classe Audio Amplifier has no output, begin by inspecting the connections. Then, check the output relays, the power supply circuits (positive rail, negative rail, and Mosfet supply), and the output transistors.
How to fix Classe Audio Amplifier that won’t turn on?
If your Classe Audio Amplifier won’t turn on, check the connections, fuses, soft-start circuit, relays, and power supply circuits (positive rail, negative rail, and Mosfet supply).
What to do if Classe Audio Amplifier has smoked components?
If you find smoked or burned components in your Classe Audio Amplifier, check for shorts between components and ground. Also, check the output transistors, output relays, and power supply circuits (positive rail, negative rail, and Mosfet supply).
How to eliminate excessive buzz from Classe Audio Amplifier?
To address excessive buzz and/or hum in your Classe Audio Amplifier, check the electrical lines and inspect for a ground loop in the system.
How to fix oscillation in Classe Audio CA-400?
To resolve oscillation issues with your Classe Audio Amplifier, check the source, the capacitors on the main board, and the 4.7? resistor.
What to do if Classe Audio CA-400 has intermittent signal?
If your Classe Audio Amplifier has an intermittent signal, check the connections and replace the shield wires.
