For example my mic Sony ecm t 150 (wonderfuol small mics) cause distorsion via Line in and via Mic In ,with his battery box and without his battery box(minidisc give 2.5 volt on mic in to work microphones who need battery).Only wiht my old Sony Ecm 909 mic this minidisc wotk fine but it is to big! i need small binaural mics to record the show! I've tried record in Auto rec and Manual Rec but the result is distorsion!! Can anyone help me? I must buy Sharp minidisc ? Which Sharp model work good to record live music? I need a model who can record in Lp2 speed!!! and if is possible manual rec in defaul(Sony 707 auto rec is on default)
