Stereo speaker protection.
The module is built on a specialized chip and provides acoustic protection in cases of:
1. Transients when turning on the amplifier
2. The failure of the amplifier and, as a consequence, the appearance of a constant voltage at its output.

The principle of operation of the device is based on opening the circuit between the amplifier and acoustics using a relay. When the power is turned on, the relay contacts are open and transients accompanied by clicks and pops pass without the participation of acoustics. After 2-3 seconds, the relay switches on the circuit between the amplifier and the acoustics. In the event of failure of the amplifier, and as a result, the occurrence of a DC voltage dangerous for the AC, the relay disconnects this circuit. The device uses a high-quality original relay "" OMRON ""
Separate power supply required.
The module has an LED, the glow of which signals the connection of acoustics to.
Supply voltage 12 ... 24V
The device provides acoustic protection in amplifiers up to 200W
