K4701 - Loudspeaker DC-Protection Kit

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.

The K4701 Loudspeaker DC-Protection SELF-ASSEMBLY electronic kit requires no supplementary supply and is simply mounted between the amplifier and the speaker in the speaker cabinet and disconnects the speaker as soon as a direct current appears.

Also ideally suited for use in the car.
