4 Pin Amp output to 3 Pin headphone jack?
So this one is stumping me and I am wondering if any of the smarties on this forum can help:
I have a four pin amplified audio output on a prototype motherboard and I am looking to convert this to a 3 pin output so I can then attenuate and use standard headphones.
The one caveat is that the amplifier is push/pull. Therefore, there are no grounds- AC is fed to each speaker as the polarities have opposite sin waves. I understand they make 4 pin headphones but this will not suffice. Using one channels ground will not work either as it sounds quite distorted.
Is this possible? :confused::confused:If anyone can point me in the direction of a component or circuit that would do this I would be SO greatful! It seems simple but in reality....its over my head!
