What to do if Classe Audio DR-8 unit won’t turn on?
If your Classe Audio Amplifier unit won’t turn on, check the connections, fuses, soft-start circuit, relays, and power supply circuits, including the positive rail, negative rail, and Mosfet supply.
What to do if Classe Audio DR-8 Amplifier has no output?
If your Classe Audio Amplifier has no output, check the connections, output relays, power supply circuits (positive rail, negative rail, Mosfet supply), and output transistors.
What to do if Classe Audio DR-8 Amplifier has blown fuses?
If your Classe Audio Amplifier has blown fuses, check for a short between the fuse and ground, and inspect the power supply circuits, including the positive rail, negative rail, and Mosfet supply.
What to do if Classe Audio DR-8 turns into protection?
If your Classe Audio Amplifier turns into protection, check for smoked or burned components, the power supply circuits (positive rail, negative rail, Mosfet supply), the source and load, the protection circuit, the sensor wires between the sensor PCB and control PCB, and the output transistors and Mosfet drivers.
Why does my Classe Audio DR-8 Amplifier have excessive buzz and/or hum?
Excessive buzz or hum in your Classe Audio Amplifier may be due to electrical line issues or a ground loop in the system. Check both of these potential causes.
What to do if Classe Audio DR-8 Amplifier has smoked and/or burned components?
If your Classe Audio Amplifier has smoked or burned components, check for a short between components and ground. Also, check the output transistors, output relays, and power supply circuits (positive rail, negative rail, Mosfet supply).
Why does my Classe Audio DR-8 Amplifier have oscillation?
Oscillation in your Classe Audio Amplifier might be caused by the source, capacitors on the main board, or the 4.7? resistor. Check these components.
What to do if Classe Audio DR-8 Amplifier has intermittent signal?
If your Classe Audio Amplifier has an intermittent signal, check the connections and replace the shield wires.
Why does my Classe Audio Amplifier have intermittent / fast output relay click?
An intermittent or fast output relay click in your Classe Audio Amplifier could be due to DC offset before the relays, the relays themselves, or the capacitors on the protection circuit. Check these components.
