Had an idea and haven't got a clue about if it will work or not lol thought I would pass it by you guys if you dont mind?
Basically I have a small 2 channel mixer I have made just from resistors but this means that the mixed output from this mixer has a lower output volume than just 1 of the outputs before the mixer.
I had an idea of how to get the mixed output level to be the same volume as each individual output and wondered what you think? I have attached a schematic. Or maybe you have a better/more simple way of doing this?
Thanks in advance

A resistive mixer will always attenuate the signal a little. Just add an amplifier after or before it.
The circuit you show won't work because it confuses AC and DC. You can't feed an AC signal straight to an optoisolator, it needs a DC bias too. Diodes isolate DC, not AC. I think you need to go away and do some reading.
