Product Description

The UM92.1S is a large-diaphragm, multipattern tube microphone with Gefell’s trademark PVC-diaphragm M7 capsule.

The M7 capsule is a center-terminated, dual-diaphragm design, and supports three polar patterns. A switch on the power supply allows selection of Cardioid, Figure-of-8, or Omnidirectional patterns.

The amplifier circuit is similar to some of Gefell’s historical models, the CMV 563 and UM 57, but has been updated with modern components. The tube is an EF 86 pentode, reportedly of Russian origin, wired in triode configuration.

The “.1” Gefell mics, including the M92.1S and UM92.1S, 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.
