Microtech Gefell M 290 Series Microphone

Microtech Gefell M 290 Series

A series of highly regarded nickel diaphragm capacitor microphones
with a membrane thickness of less than 1µm

• M 294 – Cardioid with a presence boost (c. +5dB at 8kHz)

• M 295 – Cardioid

• M 296 – Omni

• M 297 – Wide-cardioid (Hypo-cardioid)

This series of microphones have a nickel diaphragm 16mm in diameter (22mm for the M 296 omni) with a membrane thickness less than 1 µm.

The capsule is a ceramic capsule with the backplate coated in a thin layer of chromium that is then teflon coated to preven short-circuits in the case of the diaphragm bottoming out.

The capsule head contains an integrated shockmount that serves to control the mic’s directionality and to reflect off-axis sounds away from the diaphragm, helping to retain high-frequency detail that might otherwise be smeared by “modal interaction” and phase cancellation produced by reflected sounds.

The pre-amplifier circuit is a low-noise, transformerless design that is linear from 5Hz to 100kHz.

M 294 cardioidexhibits a desirable treble boost rising nearly 5 dB in the 8 kHz region gives this microphone its special clarity.

M 295 cardioid ideally suited for close proximity recordings, with a virtually linear response in the upper range and a gentle roII-off in the Iower frequency region to counteract proximity effect.
