Hi,
So I just got myself a cheap AliExpress amplifier, but at about half gain, it has quite a bit of 'hissing' noise, I allready tried lowering the input volume using a potentiometer and turning the gain all the way up, since there is no hissing sound when the gain is set to max, but that didn't help, since the hissing still persisted, so it must have something to do with the voltage it's trying to get?
Does anyone know what might cause this, and/or if there is a fix for this?
No problem if it can't be fixed since it cost only €4, but still, would be nice
this is the amp: https://aliexpress.com/item/4000175137078.html?spm=a2g0s.9042311.0.0.7c834c4d7kEkvV
this is the chip the amp uses: http://www.ti.com/lit/ds/symlink/tpa3118d2.pdf
Thanks in advance!
