Hello, I've got a Sharp MT270 (line in, no mic in) that I'd like to use to record my band rehearsals. I'm not worried about sound quality, these recordings are just for us, mostly as a reminder of what we were doing last time we rehearsed. I'll upload them on a pc and share the recordings as mp3's to the band members each week. I dont want to drag a lot of recording gear along to rehearsals, hence the idea to use the MD which I have, and I don't want to spend any money either However, I need a cheap mic that will record into the line-in on the MT270. I found this powered mic on Thomann's site. Would it work for me? Thomann stereo mic ... or would I need a preamp as well? I'm not sure if these powered mics actually amplify the signal or not. Thanks in advance for any help
