It seems that Breeze Audio dual TPA3116 100W * 2 has its input gain set to 32dB which is too high.
I want a cheap dual TPA3116 amp with the input gain of 20dB.
Does anyone know such a thing?

Yes, the TI datasheet, section 6.5, tells that it can be set to 20dB gain:

It is a matter of removing a two (SMD) resistors (one for each chip) on the "Breeze Audio" board.

I'd like to avoid soldering and desoldering because I don't want to buy expensive soldering equipments for now.
Then cut them with a very sharp knife. However, I would desolder the resistors with a cheap but good soldering iron. Or have it done by a fellow DIYer that has a soldering iron. Looks better and is more or less a guarantee for reliable operation.
Any TPA3116/8 board can be changed to 20 dB amplification.

It would be cheaper and easier to buy FX1002A, TPA3251 amp, or TPA3255 amp.
FX1002A comes with DIP switches for input gain.

You might need the soldering iron more often when doing audio stuff. In fact you can't do without.

In the future, I will probably purchase a proper set of soldering equipments for keyboards and amplifiers.
