MT 71 S

From Microtech Gefell:

The MT 71 S studio condenser microphone features our legendary original M7 capsule with PVC diaphragms which is renowned for its sound quality, outstanding performance, high sensitivity, and improved signal-to-noise ratio. The MT 71 S guarantees particularly clean and colourless sound reproduction. It is well-suited for instrumental and vocal soloists in radio and television broadcasting and any other kind of accurate production. The pressure gradient transducer is a dual-capacitor design that uses a single brass back-plate and two large-diameter gold-plated plastic diaphragms.

The transformerless circuit design substitutes the previous transformer for a symmetrical output stage yielding a superb transient response combined with a high RFI rejection. The circuit technology also achieves a wider dynamic range by lowering the self-noise floor and increasing the headroom for loud signals. A 10 dB attenuator has been installed to reduce the sensitivity of the microphone when placed near very loud sound sources. A sensitivity reduction for low frequencies can be utilized to suppress the proximity effect.
