Purpose of opamps on a 3886 board?

uzernaam · 22nd October 2010, 09:27 PM

I've seen many 3886 boards, none of them had opamps that I was aware of. There is one on ebay that has the NE5532 onboard.

Why would it be there?

Effect on sound?

Thanks!

There are two reasons I can think of for putting an op-amp on an LM3886 board. An input buffer or a servo.

the opamp + the chipamp could be arranged as a composite opamp.
