M60 FET Master Set

The M60 FET Series is designed to utilize the same interchangeable TK6x capsules as the TEC Award-winning ELA M 260 small diaphragm tube microphone. The M60 FET Master Set features one M60 amplifier paired with three interchangeable capsules, including the TK60 cardioid, TK61 omnidirectional and TK62 hypercardioid.

Sonic Characteristic

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.

Circuit Design

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.

Construction

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.

Accessories

The M60 FET Master Set ships complete with TK60 cardioid, TK61 omnidirectional and TK62 hypercardioid capsules, a SGMC-5R 5-meter XLR cable with right angle female connector, M761 elastic shock mount, and foam windscreen, all packed in an FC61 zipper carrying case.

TK60 Capsule

TK60 Cardioid Capsule

The TELEFUNKEN TK60 is a small diaphragm cardioid capsule used with the ELA M 260 tube microphone and the M60 FET microphone.  Featuring a 6-micron gold-sputtered membrane measuring 15mm in diameter, the TK60 has a surprisingly full low end for a small diaphragm capsule, and offers a quick and accurate transient response.  These small diaphragm capsules are tested to a strict ±1dB sensitivity tolerance.  The frequency response is flat from 150 Hz to 7 kHz, with a smooth, airy presence peak at 8 kHz making it ideal for drum overheads, acoustic guitar, and other acoustic instruments.

TK61 Capsule

TK61 Omnidirectional Capsule

The TELEFUNKEN TK61 is a small diaphragm omnidirectional capsule used with the ELA M 260 tube microphone and the M60 FET microphone.  Featuring a 6-micron gold-sputtered membrane measuring 15mm in diameter, the TK61 offers a large, open sound perfect for capturing the subtle nuances and space of your recording environment.  The frequency response is flat from 20 Hz to 5 kHz, with a smooth, airy presence peak at 8 kHz. These small diaphragm capsules are tested to a strict ±1dB sensitivity tolerance.  When used with the diffuse field spheres in the ELA M 260 Tri-Mono system, the TK61 omnidirectional capsule captures the ambience and vibe of your room to breathe life into any recording.

TK62 Capsule

TK62 Hypercardioid Capsule

The TELEFUNKEN TK62 is a small diaphragm hypercardioid capsule used with the ELA M 260 tube microphone and the M60 FET microphone.  Featuring a 6-micron gold-sputtered membrane measuring 15mm in diameter, the TK62 provides a wide cardioid pattern flat in response from 150 Hz to 3 kHz, with a dip at 6 kHz and a smooth, airy presence peak at 8 kHz. These small diaphragm capsules are tested to a strict ±1dB sensitivity tolerance.  This tightened polar pattern is great for use on cymbals, percussion, and as a stereo pair for live performance recording.
