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
• Vacuum tube electronics offer greatly enhanced output and constant, optimized impedance to
the ribbon element
• Extremely low residual noise
• 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
