DC offset faults

A “DC offset fault” is not an amplifier fault, but a speaker protection mechanism. If the amplifier is supplied with a DC voltage (rather than the expected AC voltage) for an extended length of time, the coils in the attached speakers will eventually burn out (or, in extreme cases, catch fire). The P1000 can detect this condition, and cut the current to the speakers.

DC offset faults can occur intermittently in all set-ups, particularly if a tuner or satellite receiver is connected. If it occurs frequently or predictably, please contact your dealer for advice.
