Hello again, fine folks,.... As it looks like I'll be needing an 8 channel pre amp when I get the MYGDA epansion card for the AW 2400 to give me 16 simultaneous mics for my drum kit,( pheeeeeewwwwwww ,..takes deep breath ! ) can any one recommend a suitable unit ? I've spotted a 'Mackie Onyx 800R' that seems to be ideal,( aside from the £ 1000 price tag ). Also, would a transistor, tube, or hybrid type be best ? Ermmmmm,.. Over to you learn'd people,.. Cheers,..... Dan.
