Ran the mics lastnight taping a local show...same result. Right channel fine, left channel little to no response. Switched capsules, bodies, cables, PS-2 inputs and came to the conclusion that capsule originally of the left channel is faulty. I tightened everything up today and havent tested it out yet, but Im coming to the conclusion that capsule may be bad as everything was tight before I set up lastnight with the exception of the small screw on the bottom. Screw has been tightened as of today, need to test. Do these capsules go bad and what are my options?
