I have a Sure/Wondom AA-AB35281 amplifier board.
The specs PDF states:
"Gain: Min 28.5, Typical 30.5, Max 32.5"
This leads be to believe the gain setting is adjustable.
But the PDF doesn't state whether it can be adjusted or how if so.
Does anyone know if it can be adjusted and if so, how?

Okay, so it's not like the TPA3116 board I used previously where it was possible to adjust the gain by changing / removing a resistor.
I wouldn't recommend trying that. If the gain is too high, use an input attenuator (pot or a series resistor).
Nonsense, that's what the gain resistors are for with the TPA3116. I dropped the gain to 20dB simply by removing a resistor.
So you know it already. Why ask?.
I think Rayma did a good suggestion, no nonsense at all.
You should ask why he recommend that?

The resistors on a tpa gain circuit go nowhere near the audio signal so is entirely different. This chip doesn't have an adjustable gain so the above suggestion is the easiest to implement. Perfectly good.
Sorry, I meant it's nonsense not trying that on the TPA as the documentation explicitly states that's the way to change gain setting.
I didn't mean his remark was nonsense regarding this amp board.
My bad, bad communication. Mea culpa.
