The UMT 800 is a large format studio microphone featuring a pickup capsule with a long history of proven performance. Five polar patterns make this mike an ideal choice for a wide range of professional and semi-professional recording situations. The UMT 800 produces a clean, colourless sound, ideally suited for accurate recording of instrumental and vocal soloists in music studios, motion picture scoring stages and television broadcast studios. Two distinguishing characteristics of this microphone are its high sensitivity and outstanding signal to noise ratio. The pickup capsule is a pressure gradient transducer using dual membranes and a single brass back plate. The large diameter plastic membranes are sputtered with gold. Varying the polarization voltage to the membranes with the pattern switch, located just below the head grill, produces five patterns: omni, wide cardioid, cardioid, hyper-cardioid and figure 8. The direction of maximum sensitivity is radial to the head grill, i.e. side addressed. The microphone amplifier is a transformerless design with a symmetrical output stage. This design yields a wide dynamic range and a low self noise floor. The sensitivity can be reduced by a 10 dB switch mounted on the body of the mike when miking extremely loud sound sources. A low frequency roll-off switch, also mounted on the body of the mike, reduces proximity effect when close miking. The microphone is equipped with a 3 - pin XLR connector fitting to a microphone cable, e.g. C 70. The UMT 800 uses 48 volt phantom powering according to the international standards DIN 45596 and IEC 268 -15. It is available in a black matte or satin nickel finish.
