Microtech Gefell UM 57 – Vintage Studio Condenser Microphone w/ Original M7 Capsule

OVERVIEW

The Microtech Gefell UM 57 stands as a true icon in the world of professional audio, faithfully reissued with its original M7 capsule design to preserve the unmistakable sonic signature that shaped countless classic recordings. At its core lies a large-diaphragm capsule with hand-crafted, gold-plated PVC diaphragms, delivering a smooth, natural response with exceptional detail and warmth. This is the sound of heritage – rich in character, yet precise enough for modern production demands.

Driven by a carefully selected EF86 vacuum tube configured as a triode, the UM 57 offers a harmonically rich and musical response that solid-state microphones simply cannot replicate. The included UN 57 power supply not only delivers stable operating voltages but also enables remote switching between omnidirectional, cardioid, and figure-eight polar patterns, giving engineers full control over spatial capture and tonal balance.

Finished with a distinctive hammered patina, the UM 57 embodies both visual and sonic craftsmanship. Supplied as a complete system – including power supply, connection cable, elastic suspension, and protective suitcase – this microphone is a premium solution for studios seeking vintage authenticity with uncompromising build quality and performance.
