I sent it back to authorized repair, FDW, and they said mic checked out ok. Something is very weird. Any ideas what i could be doing wrong? or could check?
Is this a brand new mic? Did it work properly before, or did it just become noisy?
Does the noise change when you turn on phantom power? If so, how?
Are you sure your mixer(s) are putting out a full 48 V. phantom power. Some 80's and 90's Secks were made with 24volt phantom power. I actually still own one. That's fine for a C-1000 (which will work down to 9 V.), but won't work with a MiLab DC-96B. Was the Mackie phantom power switch (usually on the back panel next to the mains switch) on?
The few Milabs I've used have been incredibly well constructed (a DC-96C and a matched pair of D-196s) and totally reliable.
The DC-96B has the same rated output level as a C-1000 (-44dB/6mV/Pa.) and a much lower noise level). It should be just as sensitive as the AKG and much quieter.
Have you checked your mic cable to be sure that 48 V. phantom power is available on both
pins 2 & 3 of the mic connector? Have you tried another mic cable?
The DC-96B is a low current mic and only uses 0.6 mA (as opposed to 4.2 mA for the "C") so any mixer should easily be able to power it. It does need a full 44 to 52 volts.
It's always possible that the mic has (or had) a loose connection that "healed" itself when bounced around during shipping back to the repair facility.
