About this document
Speaker Protection Circuit Overview by Santosh Talankar is a document available to read on EtoBox.
The document describes a speaker protection circuit that protects audio amplifiers and speakers from DC voltage. It has two versions that function the same. The circuit monitors the amplifier output for DC and delays connecting speakers after turn on. It disconnects speakers if DC is detected, like if the amplifier fails. It connects speakers through relays once the output is safe. The circuit requires an auxiliary 9-12V AC or DC source and has status LEDs.
