I brought a sanwu blue tpa3116 on ebay. It was advertised to have a auxiliary input, it had pictures of it with one also. does anyone have a clue on how it could possibly add one? Because bluetooth is great but it lacks in quality. Cheers
The board with the line-in is a different board. (1 more button)
The way to implement/inject a line-in with your board would be to open up the audio lines after the Diff2Se circuit (a 5532 would guess) and put in a switched 3.5mm jack. These interrupt the audio from the BT module when a plug is connected.
Question again: What the bt audio quality problem with these board? (The CSR chipsets are pretty descent)
Ok cool. I've just heard a wire connection is preferred over a bluetooth connection. But il take your word for it. I'm sure it's decent it looks like it's great quality. I think I will stick to bluetooth, I just wanted another option for connection
