Two DC Detection + SS Relay boards are required to handle two channels of a stereo amplifier.
Amp Control System is a microprocessor controlled monitoring board that will shut down the amplifier, sending a signal to disconnect the speakers on any sign of a problem from the amplifier it is connected to. It also provides soft-start functionality.
It has a connector that is daisy chain connected to multiple DC detection /speaker relay boards.
Please select SMD or TH board variant.
