OK, my dads mate gave him a mic abnd he gave it to me... I plan to use it to record, but I've no idea what kind of mic it is, and therefore how to use it! This is everything it says on the mic itself... what does this mean, do need to use phantom power/or not, and what kind of recording quality will I get from it? Dynamic Microphone 500 ohm & 50k ohm Cardioid DM-1000D It was a switch between low and high impedance Help?!
