Neumann U47 Fet

A Legendary Heritage, Redesigned for Modern Sources

A direct descendant of the legendary tube U 47 that shaped recordings from 1949 to 1960, the "U 47 fet" retains the large diaphragm K 47 capsule as well as a generous output transformer for a consistent sonic character. Its transistorized FET preamplifier section translates the vintage model's DNA into an architecture designed for today's studio demands, with more headroom and excellent performance at high levels.

Who Is It For and What Are Its Uses?

The "U 47 fet" is aimed at professional studios as well as demanding home studio users seeking a microphone that is both musical and robust. Its balanced response with a subtle bump in the upper midrange makes it formidable on kick drum, bass cabinets, brass, and guitar amps. It also shines on vocals, whether crooners or powerful singers, maintaining presence and definition in the mix.

Features and Sonic Advantages

Signature and Mastery of Extreme Levels

Thanks to its cardioid directivity and pressure gradient design, the "U 47 fet" captures the center of the source with authority while controlling ambient sound. The -10 dB pad extends SPL handling to 147 dB (THD 0.5%), while the low cut cleanly removes extreme low frequencies in close proximity, especially in front of a bass speaker or kick drum.

Control and Studio Integration

The pad and low cut switches are accessible on the rear of the body, and a switch near the XLR connector provides an additional -6 dB output attenuation to match vintage preamps with low headroom. The unilateral swivel mount facilitates precise positioning in front of the most demanding sources.
