    Interesting product that provides various protections that potentially could damage your loved speakers. Important observation is that the power amp has to have common grounf for speakers output; otherwise it cannot be used unless you modify it with a 4 channel relay to conmute both cables of each speaker or use two different protectors; one for each speaker..

    I connect it with 2 separate module amplifiers. This unit has a common ground. The result, due to my mistake is that I burned both modules. Know I know. Otherwise the unit is working ok

    Unfortunately I did not receive the package! It’s at some sort of transfer point, far enough away from where I live.
