This mono loudspeaker protection circuit works with any audio amplifier from 1 to 100 Watts. It will protect your speakers from signal spikes and your ears from unpleasant surprises! It completely eliminates the possibility of loud speakers being damaged due to overloads.
The circuit is activated by peak signals, excessive output power and also the presence of DC voltages across its input when there is a fault in the output stage of the amplifier. It is connected in the output of the amplifier and when it is activated it inserts a 56 ohm resistor in series with the speakers attenuating the output of the amplifier by -15 dB.
See Order Code 1112 for a Stereo Loudspeaker Protection with Delay. Kit includes solder for assembly.Specifications
