Clipping Fault

The input and output audio signals are compared to determine when clipping is occurring.

Occasional clipping will cause the CLIP lights to flash and will not trigger this fault. However, if a

severe overdrive condition occurs, this fault is triggered to prevent damage to speakers. This fault

indicates that the amplifier has been driven very hard into voltage clipping. Both channels are

muted to protect the amplifier and speakers. A power reset will be required.

Fault Display:

 POWER light is Flashing

 One or both CLIP lights are On

 Both TEMP lights are Off

 Both MUTE lights are On

Typical Causes:

 The sensitivity switch may be set too high

 Speaker cables may be shorted

Required Actions:

 Check for shorted speaker cables

 Check the position of the SENSITIVITY switch

 Move the sensitivity switch down one or two positions if necessary

 Turn down the audio source

 Restart the amplifier
