The M9 is a cardioid single tube externally biased condenser microphone that features servo-valve technology. The M9 is a natural bridge between the valve technology developed for the VX2 microphone and the servo opamp technology developed for the M-Series microphones. The head amp in the M9 microphone is a 12AX7 tube in a circuit that is optimized for super wide dynamic range and low noise. The output stage is a high speed dual opamp in a balanced differential configuration that allows long cables to be used without affecting microphone performance.
