Troubleshooting, AC mains fuse is blown

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. To reset the ampliﬁer, press and hold the Standby button for 3 seconds to power down the ampliﬁer. Then disconnect all inputs and outputs.

•Then try powering up the ampliﬁer by pressing the Standby button. If the LED continues to blink, there is a fault condition in the ampliﬁer itself. It should be powered down, disconnected from the AC mains and taken to your Classe 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).

4.The AC mains fuse is blown.

There is a speciﬁc troubleshooting procedure for a blown AC mains fuse, since this rare occurrence sometimes indicates a signiﬁcant problem. Please follow the following steps, in order:

a.Disconnect your ampliﬁer from the AC mains, as well as from its input connections and speaker connections, and remove the fuse cover on the rear of the unit.
