specification
The MT 71 S studio condenser microphone, equipped with our reliable large-diaphragm capsule, features outstanding performance, high sensitivity, and an improved signal-to-noise ratio. The MT 71 S guarantees particularly clean and colorless 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 backplate 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.
