Other Parts Discussed in Thread: TPA3220EVM-MICRO, , TPA3220
Hello,
I do not understand the purpose of R16 in this circuit. It creates a minimum gain that is much too high. Can this resistor be removed and replaced with a jumper?
Also, please be advised that when this board is used with the TPA3220EVM-MICRO, the TPA3220EVM-MICRO will not supply the required 12V power needed for operation. The literature would lead you to believe that all modules with the AIB connector would supply this power. Unfortunately, there is no place provided on the SIDEGIG-GUITAREVM to accept an external source other than the AIB connector.
Thanks,
Tom
