9 polar patternsPeluso Microphone Lab 22 47 LE

Multi-Pattern Tube Condenser Microphone

The 22 47 LE is a large-diaphragm tube mic “inspired by and styled after” the Neumann U-47.

That said, it is not a replica or reproduction. Purists note several differences:

  • The U-47 offered only two pickup patterns, cardioid and omni, whereas the 22 47 LE offers 9.
  • 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.

Peluso 22 47 LE kitThe 22 47 comes in three flavors; the LE version is distinguished by the use of a German “steel” tube, currently a hand-selected EF-12 or EF-13. The SE version swaps this for a tube of US origin; the SE tube is arguably less authentic, but has lower noise.

(The original U-47 used a Telefunken VF-14, a steel tube that Neumann abandoned 50+ years ago because of its unavailability.)

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

Peluso 22 47 LE kitThe microphone ships in a flight case with a dedicated power supply and cable, a shockmount, and a padded wooden storage box.

The Peluso Microphone Lab 22 47 LE is also known as: 2247LE.
