Hi;
I just got this amp from eBay.
TPA3116 Digital Amplifier Board Dual Channel 30Wx2 With Treble Bass Tone | eBay
I ordered this version because it's cheap and it has tone controls - I need them for the project for my father.
First thing is when I touch potentiometers the amp makes some noise. I suppose I need to wire the housing of all potentiometers to ground? Where should those wires go from the housing? To signal ground to the input or somewhere else?
Second thing is this amp has no output chokes (filter). I can't hear there is anything wrong when listening to music because of that but I wonder if it's OK to run the amp without output filters.
I would appreciate some help.
Regards;
