Burn out of a power amplifier's output stage nearly always results in a dangerous direct current to the loudspeaker's terminals. In turn, this results in loudspeaker burn out. This protection unit, requiring no supplementary supply, is simply mounted between the amplifier and the speaker in the speaker cabinet and disconnects the speaker as soon as a direct current appears. Ideally suited for protecting expensive compression divers.
