Could you please explain the loud humming (electrical) sound I hear when I plug a microphone into the "mic in" port of my sound blaster awe 64 value card? The only thing I see on the microphone is "AM 32"
AM32 is not a Shure model number. Hum problems can be caused by many different things. We suggest you read: SM58 or any professional microphone connected to a computer sound card
We also suggest you contact the manufacturer of the computer sound card for assistance.
