Velleman Kits & Projects

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.

Can be used for recreational purposes or to simulate a hot summer night. Automatically comes on when darkness falls. Cricket repetition (time between two crickets), effect and tone are adjustable. Adjustable light sensitivity.
