Microtech Gefell UM 92.1 S

Description

The UM92.1S is a large-diaphragm, multipattern tube mic built around the EF 86 pentode (in triode configuration). Gefell’s dual-membrane M7 capsule provides three pickup patterns: cardioid, omni, figure-of-8, via a switch mounted on the separate power supply.

The mic ships in a metal suitcase and includes a dedicated power supply (p/n UN 920.1), power cable (p/n C 92.1), elastic suspension mount (p/n EA 92), and gray foam windscreen (p/n W 92).

The mic is available in three finishes:

  • satin nickel (p/n 211138)
  • matte black (p/n 211139)
  • 24K gold anniversary edition

US customers should be aware that Gefell mics include RF/EM protection circuits required for CE compliance. Although US restrictions on electromagnetic radiation are less strict, Gefell does not currently provide US-only circuits.

According to Oliver Archut of TAB-Funkenwerk, these EMI protection circuits “choke” the sound and introduce phase shift. He has provided instructions for removing the EM/RF circuitry of the UM92.1S. See also this clarification.

The Microtech Gefell UM 92.1 S is also known as: UM92.1S.
