Troubleshooting
In general, you should refer any service problems to your Classé dealer. Before contacting your dealer, however, check to see if the problem is listed here.
1.No sound, and Standby LED is not lit.
•The amplifier is not plugged into the AC mains, or the AC mains are down (circuit breaker, fuse).
•A
•The AC mains fuse is blown. See Troubleshooting #4, below (or contact your Classé dealer).
•The AC mains is out of range. Check the line voltage supplying the amplifier.
2.No sound, and Standby LED is blinking red.
•The protection circuitry has been engaged.
•Press and hold the standby button to reset the amplifier.
•If the amplifier does not reset or continues to go into protection mode, disconnect the amplifier from the AC mains, and disconnect all inputs and outputs.
•Try to power up the amplifier again, connecting it only to AC power. If the LED continues to blink, there is a fault condition in the amplifier itself and it should be disconnected and taken to your Classé dealer for service.
•If it powers up without any difficulty, first power it back down and reconnect only the inputs, then restart the amplifier. If it again powers up normally, there may be a problem such as shorted speaker leads. Check the connections to confirm there are no obvious shorts, then connect first one channel, followed by the other, to confirm either that there is no longer a shorted lead or if there is, which channel is shorted.
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).
•The amplifier logs all protection circuit
Contact your dealer to assess the likely cause of the trouble.
