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.
