Two-channel speaker protection against DC voltage

Two-channel speaker protection is a module designed to protect speakers from DC voltage, which can cause damage. It is installed between the amplifier output and the speakers.

Key features:

• Delayed activation: After powering on, the output remains disconnected for approximately 2-3 seconds.
• Relay status indication: An LED indicates the current operational status of the module.
• Automatic output cutoff: If DC voltage of about 1 V appears at any input, the output in both channels is disconnected.

The device is assembled and tested, ensuring high quality and reliable operation.
