Perfect engineered speaker protection, practicall small but sufficient, it match ideally for diy projects, if you change some values, it could be adjusted for different level of sensitivity! For me it’s just perfect for my diy projects

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..

This is a fine, useful product, well-designed and well manufactured. Excellent value. HOWEVER... Don't do what I did and try to use it with a popular and inexpensive Power Amp (e.g., 15W TDA7297 Dual-Channel Amplifier Board) which has outputs which do not share a common (usually ground) connection. Connecting the protection circuit to both speaker outputs of such an amp will very quickly destroy it by shorting the outputs, which must always remain isolated from each other. Be careful!

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
