User's Manual

microphone cable is in good working order. Use another microphone to establish that the signal
path is indeed working. If this fails to resolve the problem, contact the factory.
If the mic works but is noisy or has low output, there could be a problem with the ribbon element
or the vacuum tube. In either case, the microphone is not user serviceable and repairs should be
directed to an authorized service center.
Features
Very high overload characteristics – maximum SPL greater than 135dB

Ribbon element is unaffected by heat or humidity
Absence of high frequency phase distortion
Excellent phase linearity – even off axis
Equal sensitivity from front or back of element
Consistent frequency response regardless of distance
Compact size
