Sorry I missed this before, there are several inputs on the back of the Altec Lansing....an S-video input, a 3.5 mm auxilary input & a composite video input. NOw, I'm no expert, but I'm going to guess that the 3.5 mm aux input would work for a mic. Hope this helps! FYI, the one we have is technically called the IM7, here's a link to the product site Altec Lansing Products: IM7
