With over a year and half of development and beta testing with top recording engineers, the newly designed M60 FET (Field Effect Transistor) small diaphragm microphone is TELEFUNKEN Elektroakustik's first non-vacuum tube, FET-based solid-state condenser microphone. 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 20Hz to 50KHz. 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. Designed to utilize the same interchangeable TK6X capsule systems as the TEC Award-winning ELA M 260 small diaphragm tube microphone, the M60 FET is an excellent tool for both acoustic and percussive sources. The TK60 cardioid, TK61 omnidirectional and the TK62 hypercardioid capsules are offered individually or in complete sets, as well as matched pairs of M60 FET amplifiers and capsule sets for stereo recording capabilities.
