I am planning my hardware for my system now, and am planning on using Centrafuse. I want to be able to have both a microphone for voice command and phone use, and a line in for XM. The Centrafuse recommended mic is the Andrea unit that plugs into a USB dongle, so this would eliminate any other line in on the system if used, correct? If so, I would need a plain 1/8" microphone, anyone have one to recommend that would work well in this setup?
