I just bought an Alesis MultiMix 4 USB.
What I wanted it for was the ability to connect 4 microphones to my computer via USB, in order to record a podcast where 4 people could be individually miked. I was so concerned about USB driver issues, that I think I did not look into other issues.
The problem is that if I plug a microphone in to the inputs for channels 3 and 4, I get absolutely no response.
What puzzles me is that I can use the 1/4" line-in jacks on channels 1 and 2 and they work fine. So what's the deal with channels 3 and 4? I can clearly see they don't have as many controls and features as channels 1 and 2, but I thought they would at least be able to take a line in from a microphone.
What is going on with channels 3 and 4? Why do they not register any microphone input?
