Microtech Gefell's MT71S is a cardioid-pattern FET microphone that features their M7 dual-membrane, gold evaporated capsule.  The MT71S also included a low-noise capsule amplifier for superior transient response, wide bandwidth and a natural uncolored sound.  The slim design benefits the MT71S with less acoustic field disruption around the microphone and greater placement ease when close micing instruments.  Ideal for recording, broadcast, voice-over and live sound reinforcement.

Mounted inside on the MT71S's triangulated pedestal is an M7 capsule, which is a pressure gradient transducer that is renowned for its warm and natural tone.  It features a dual 1" (25 mm), 24-karat gold evaporated membrane design with a PVC substrate.  The triangulated capsule pedestal deflects unwanted body reflections away from the microphone, reducing phase cancellation and comb-filtering.  This offers greater source detail, improved upper-harmonic reach, and a more articulated rendering.

The accurate and colorless sound of the MT71S is well-suited for instrumental and vocal soloists in radio and television broadcast.  Comes in it's own beautifully hand-crafted wood box.
