Greetings
I posted this over at tapeheads to no avail so figured I’d try over here.
Earlier this year I bought a 424 mki that was not working correctly. I recently had it fixed up (new motor, loose joint soldered) and cleaned inside and out. But I've run into an issue I can't figure out. When I record guitar or bass by direct input on any of the channels, the recording comes out great. But when I try to use my mic (SM57), I get a pretty harsh buzz/hum that makes recording with it almost pointless. The audio that gets recorded is super quiet too- I have to basically yell into the mic to get the meters to spike into the red. Recording an acoustic guitar for instance is pretty much impossible.
A few more notes to put the issue into context:
- the mic and cable (XLR female - 1/4 in) both seem fine. Sound and work great just plugged into an amp or when recording with interface/computer. Cable is almost brand new, mic is in great shape
- I've tried multiple power outlets in my house and the issue persists. I also know I'm using the correct power supply
- the buzz changes a bit if I move the mic around or jiggle on the 1/4 in input
-gain on Tascam is set correctly for mic
My thought is that this might be a grounding issue, though I'm not electric savvy enough to know what to do about that. I have a small mixer that I may try hooking up between the mic and tascam to see if that helps, though I'm missing the power supply for that currently. I wish I had more mics and cables to test out but I don't.
Any help is greatly appreciated! thanks
