The UMT 70 S condenser microphone, equipped with our reliable large diaphragm capsule, features outstanding performance, high sensitivity, and an improved signal-to-noise ratio. The microphones guarantee 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 back plate and two large-diameter gold-plated plastic diaphragms. Varying the polarization voltage applied to the diaphragms results in three directional characteristics: omni, cardioid, and figure 8. A ring at the bottom of the microphone’s head grille is used to select the pattern. 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 when close-miking with the cardioid or figure 8 patterns.
