Overload protection is operating.

Check loudspeaker impedance is not too low.

Very often loudspeakers of too low an impedance can be driven at low

levels but not high levels.

Temperature protection is operating.

Ensure ventilation is not obstructed, and loudspeakers are not of too low

impedance. Switch the amplifier off for 15 minutes to cool down if

necessary.

DC offset protection is in operation.

This can sometimes be triggered by excessive mains noise etc; if so

switching the unit off and on again will reset it.

If unit will not reset then there is an amplifier fault that will require

servicing.

Switch the unit off and contact your dealer.

Output distorted and at unexpectedly low level.

Output appears to cut out frequently, independently on the two channels.

Amplifier will not operate; all input LEDs are flashing.
