Classe Audio AMP5 Manual De Usuario

23

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. 

•  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 line voltage supplying

the amplifier.

•  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.

•  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 CAN-Bus connected Classé component

or by your dealer on a PC using a special diagnostic program. 

Contact your dealer to assess the likely cause of the trouble.
