9 polar patternsPeluso Microphone Lab 22 47

Multi-Pattern Tube Condenser Microphone

The Peluso 22 47 is a multipattern tube microphone modeled after the Neumann U-47. The base model in the series, called the 22 47, is a visual clone of the “short body” U47.

None of the 22 47 mics (including the LE and LE) is presented as a replica or reproduction. Purists note several differences:

  • The U-47 offered only two pickup patterns, cardioid and omni, whereas the 22 47 mics all offers nine.
  • The U-47 had two diaphragms with a shared backplate (both the original M7 capsule and the later K47 capsule were single-backplate designs). The 22 47 has a dual-backplate capsule.
  • The circuitry uses a modern design.

The capsule in the 22 47 is a dual-diaphragm, dual-backplate design, as noted above. The diaphragms are made of 6-micron Mylar coated with pure gold. The diameter of the gold disc is 25.2mm; the backplate diameter is 34mm.

The base 22 47 “shortbody” model is modeled after a broadcast version of the U-47 in that it uses a glass triode tube in place of the original mic’s steel VF14 tube. Early versions of the 22 47 used a CE701 tube; currently, the mic uses a 6072A. (The LE and SE versions use steel tubes.)

All three models of the 22 47 provide 9 pickup patterns, switched from the power supply.

The microphone ships in a flight case with a dedicated power supply and cable, a shockmount, and a padded wooden storage box.

I’ve now used the 22 47 extensively. It has become, without a doubt, the favorite mic in my own collection… I have yet to find something this mic doesn’t sound great on.
