The M61 FET Omnidirectional package includes one M60 amplifier paired with a TK61 omnidirectional polar pattern capsule.


The TK61 features a 6-micron gold-sputtered membrane measuring 15mm in diameter, and offers a large, open sound perfect for capturing the ambience and vibe of your instrument or recording environment to breathe life into any recording. The frequency response is flat from 20 Hz to 5 kHz, with a smooth, airy presence peak at 8 kHz.

The M60 FET’s incredibly quick transient response captures nuances and subtleties with impressive precision and clarity. This results in an extremely detailed sonic image with definition and presence, perfectly suited for the complex character of stringed instruments and percussive sources.

Utilizing a unique proprietary circuit topology, this re-interpretation of the classic FET mic amplifier produces an exceptional transient response and SPL handling capabilities. Carefully selected and tested components are hand-plugged into gold-plated circuit board traces to provide an ultra-clean true Class A discrete amplifier with a frequency response of +/- 2dB from 20 Hz to 50 kHz. The output is matched with a custom American-made transformer that offers an especially low self-noise and a typical THD+N of 0.015% or better, making it ideal for critical recording applications.

The M60 FET amplifier body is finished in a durable, lightly textured black powder coat adorned with the historic TELEFUNKEN diamond badge. The microphone’s XLR connector shell complements the look with a matte black nickel plated finish engraved with the model and serial number. The TK6x capsules feature a bright nickel plated enclosure with a fine gold mesh pattern.

The M61 FET Omnidirectional system ships complete with a SGMC-5R 5-meter XLR cable with right angle female connector, M761 elastic shock mount, and a foam windscreen, all packed in an ZC61 zipper carrying case.
