Mixing 2 Audio Signals

Hi All,

I didn’t know where to post this cos you don’t have a general help section, so sorry if this is in the wrong place.

Anyway, I’m currently working on an audio project but I am now stuck with something. I now need to mix 2 audio signals but also keep them apart. I have an audio source, Left, Right and GND and I need to combine the Left and Right to form a mono channel of both combined but I also need to have the stereo channels come out again.

So left, right and gnd audio IN, left, right, gnd and mono audio out.

Apparently I should use an opamp but I can’t say I’m too familar with such devices.

Thanks for any help,

Sephers.

Google “audio mixer op amp”?
