Transformerless Condenser Microphone
with switchable polar pattern
The UMT 70 S condenser microphone, equipped with our reliable large
diaphragm capsule, features outstanding performance, high sensitivity, and
improved signal-to-noise ratio.
The UMT 70 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. 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 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 presence boost rising to about 4 dB in the 7 kHz
range. 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 perpendicular to the microphone's
axis (side addressed).
The newly developed 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 micro-
phone 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.
The microphone is equipped with a standard 3-pin XLR connector fitting to a
microphone cable, e.g. C 70.
The operation voltage for the UMT 70 S is provided by 48 V phantom power-
ing according to the international standards DIN 45596 and IEC 268-15.
The microphone is available in a satin nickel or a black matt finish.
