Microtech Gefell UMT 70 S Mikrofon
- polar patterns omni, cardioid, figure 8
- switchable attenuator
- legendary M7 capsule
- transformerless output
The
UMT 70 S condenser microphone equipped with our proven large diameter
membrane capsule features outstanding performance, a high sensitivity
and a improved signal-to-noise ratio. The UMT 70 S guarantees a
particularly clean and colourIess sound reproduction. lt is well suited
for instrumental and vocal soloists in radio and television broadcasting
and for accurate productions.
The pressure
gradient transducer is a dual capacitor design using a single brass back
plate and two large diameter gold plated plastic membranes.
Varying
the polarization voltage applied to the membranes produces three
directional characteristics: omni, cardioid and figure 8. A ring at the
bottom of the microphone's head grill selects the pattern. The
omni-directional pattern shows a slight 2 dB rise in the vicinity of
10,5 kHz while the bass response is perfectly flat. The cardioid and
figure 8 patterns exhibit a smooth treble boost rising which peaks at
about 4dB in the range of 7 kHz. This response coupled with a slight
roll-off at low frequencies, is responsible for the legendary "presence"
of this microphone.
The direction of maximum sensitivity is radial to the grill, i.e. side addressed.
The
newly developed transformerless circuit design substitutes the previous
transformer by a symmetrical output stage yielding superb transient
response combined with high RFI rejection. The circuitry also achieves
wider dynamic range by lowering. The self noise floor and increasing the
headroom for loud signals. A 10 dB attenuator is installed to reduce
the sensitivity of the microphone when placed near extremely loud sound
sources. And, a low frequency roll-off switch will reduce the proximity
effect when dose miking with the cardioid or figure 8 patterns.
The microphone is equipped with a 3-pin XLR connector fitting to a microphone cable, e.g. C 70.
The UMT 7O S uses 48 volt phantom powering according to the international standards DIN 45596 and IEC 268-15.
lt s available in a black matte or satin nickel finish.
