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 voltage specified on the rear panel.
2.No sound, and Standby LED is blinking red.
•Your protection circuitry has been engaged. The most likely cause is the “check filter” interval. The amplifier is programmed to flash its standby LED after every 2,000 hours in the operate mode as
a reminder to check and clean the air intake filter. The amplifier continues to play after the 2,000 hour threshold is crossed, but once entering the standby mode the amp will require a reset. See Care and Maintenance.
•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.
•Then 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, 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
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 events. These are viewable on the touchscreen of a
