Tonight I wanted to measure the ambient noise level using Blue Bird mics and figure out if Panasonic WM61a or Primo EM172/173 will be good enough or not. Blue Bird that is in the control room does not seem to work. May be the problem is with the pre-amplifier. The output measured by ADC/Oscilloscope is noise ( amplitude=5mV ). I will return to this issue tomorrow.
