Hi all,
I am trying to build a "simple virtual earth active (op-amp) 12 channels mixer". The problem is the attenuation is around 20db (log(12) * 20). I don't know much about audio & electronics but using ltspice I can see that if only 1 channel is feeding the mixer, I will get a very low level output (1). But if all the channels are feeding the mixer now I have the line out level (2) that i want. Is there a simple solution to have line out level no matter how many channels are feeding the mixer? Are we talking about compressor / limiter?
