Hello all,
New to this so apologies if an obvious question. I'm borrowing my friend's Porta 02 to do some acoustic guitar recording, however there is a very noticeable buzz when the microphone is plugged in which is discernible when playing back recordings. I'm using a shure sm57 with an XLR cable into a whirlwind little IMP impedance transformer to match the input. I've tried using different power outlets in the house, away from other equipment, and making sure the mic cable is not close to the power cable, but none of this makes a difference - the buzzing is only there when the mic is plugged in (it's the same on both lines, and is there in a noticeable way however I set the trim and input level). I believe this means the problem is isolated to the mic and/or cable I'm using, but they work fine when I'm doing digital recording. Can anyone give any pointers on what's going wrong? Thanks.
