Microtech Gefell's M950 is a compact, large diaphragm wide-cardioid microphone that combines an M9 gold evaporated capsule with an optically isolated capsule amplifier for low self-noise, excellent dynamic handling, and greater ease of placement.

The M9 is a full-size, 1" (25 mm), 24-karat gold evaporated diaphragm that features a hand stretched Mylar/PE substrate with a hand-drilled solid brass back-plate.  All Gefell capsules are individually sorted and matched for optimum voicing.

The M9 is mounted on a triangulated pedestal that deflects unwanted body reflections away from the diaphragm, reducing phase cancellation and the effects of comb-filtering which can mask harmonic details and limit the depth of field.  To reduce noise from vibration, the microphone capsule and electronics are elastically suspended inside the compact metal housing.  This reduces the sensitivity to mechanical impact and structure born noise.  This is further advantaged by the M950's diminutive size, which has the net result of less "vortex" or acoustic disturbance around the mic.

The M950 introduces optical isolation between the 48-Volt phantom power supply and the internal capsule amplifier circuit.  Optical isolation removes "hash" caused by contamination and ripple from the power supply, providing a pure DC supply to the element.  The M950 benefits with improved voltage stability and significantly lower self-noise.

Below the capsule, a circular PC board using the very latest semiconductor technology houses the electronic impedance converter.  A newly perfected transformerless circuit topology reduces the noise floor to an extremely low level and minimizes RFI susceptibility, while also raising the maximum output capability.  Furthermore, the use of large, oversized capacitors provided added storage for exceptional transient handling.  As a result, the M950 produces a clean, distortion-free sound over an extremely wide dynamic range.
