Troubleshooting, Ampliﬁer keeps shutting off

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. 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 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).
