Hi
I am building a setup with two cheap class d amplifiers from ebay. and a cheap Bluetooth audio player.
but I have some problems with noise in the sound.
there are no filters at all, and I think it could be from ground loop noise or noise from the power net.
what kind of filters are recommended to build ? is a audio transformator enough, to isolate the two devices ?
or do i need some more ?
thanks
