I've recently bought Sony MZ-NH600D. I love downloading my CDs but want to do some charity work in Nepal recording a Sherpa. I bought a Sony ECM-T6 tie pin mike but have the horrible feeling that the MD won't record live through a mike. On the side of the unit is the USB plug and the headphone jack which looks like a hole and a one cm rectangular slot. Please, can someone advise me what to do. Cheers George Carlyle
