Microtech Gefell UMT 70 S

Description

The UMT70S is a multipattern FET condenser with Gefell’s famous pvc-membrane M7 capsule. It is a direct descendant of the famous UM70 (also an M7 mic). The single-backplate, dual-diaphragm capsule design provides three switchable polar patterns (cardioid, omni, figure-8) controlled via a switch on the microphone body.

Additional switches provide a -10dB pad and a high-pass filter.

The omni-directional pattern shows a slight 2dB rise in the vicinity of 10.5kHz 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 7kHz. This response coupled with a slight roll-off at low frequencies is what gives the microphone its legendary “presence”.

Unlike the mic’s ancestor, the UM70, the UMT70S has a transformerless output stage. Gefell’s product description claims the new circuit improves transient response and RFI rejection, lowers the noise floor, and improves headroom over transformer-coupled designs such as found in the UM 70.

The mic is available in two colors:

  • satin nickel (p/n 211130)
  • matte black (p/n 211131)

Both are shipped in a wooden case. All accessories are optional: foam windscreen, pop filter, mic clip (p/n MH 75), stand clamp (MKV 9), suspension mount (EA 21), etc.

Looking at the frequency response graphs for the UMT70S reveals curves for the three polar patterns that are remarkably similar to those for the three patterns on the UM92.1S…

Sonically, however, you would never mistake the UMT70S for
the UM92.1S… There’s substantial difference in the low
end, with the UMT70S offering a tight, contained bottom. On the top, the UMT70S has more sparkle and shimmer, without sounding crispy or sterile. In the mids, the UMT70S has clarity where the UM92.1S has complexity…

I found the UMT70S to work on virtually everything I put it in front of… The UMT70S is the kind of mic that you can just put up and expect to sound good.

The Microtech Gefell UMT 70 S is also known as: UMT70S, UMT-70, UMT-70S.
