TELEFUNKEN M61 Omni Tri-Mono Set – Small Diaphragm Condenser Microphone Kit TELEFUNKEN Elektroakustik

The TELEFUNKEN Elektroakustik M60 FET OMNI TRI-MONO microphone set features three (3) matched M60 FET microphones with TK61 Omni capsules and 40mm diffuse field spheres. The three-microphone decca tree configuration that was made famous with classical music recordings in the 1950s features three omni microphones positioned in a reverse “T” shape, most often located over the conductor’s head. The most common Decca Tree setup employs 3x 1 meter bars from which the microphones hang in a triangle configuration; though larger and smaller bar sets can be used.

Utilizing a unique proprietary circuit topology, the M60 is a re-interpretation of the classic FET mic amplifier that 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.

The capsule assembly of the historic Neumann M-50 featured a 40mm acrylic sphere which was actually a “diffuse field sphere” built into the M-50’s capsule assembly. TELEFUNKEN Elektroakustik has created removable diffuse field spheres as an accessory for the small diaphragm M60 FET and ELA M 260 TUBE microphones.

The addition of a diffuse field sphere is the most organic way to combat both effects; reducing the loss of high frequencies as well as minimizing the reverberant information. The sphere is an accessory that attaches to the capsule end of the microphone, which effectively makes the microphone’s diaphragm part of the sphere as the sphere changes the shape of the transduction capsule. The result is a gradual and smooth rise in upper midrange and high frequency information captured by the microphone.

All M60 FET OMNI TRI-MONO SETS are supplied with three sets of TK61 Omnidirectional capsules, three removable 40mm diffuse field spheres, three SGMC-5R microphone cables, 3x M 761 elastic shock mount, and zipper carrying case.

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 matched sets of two or three capsules.
