At the upcoming 2023 AES Show at the Javits Center in New York City, TELEFUNKEN Elektroakustik (booth 421) announced that it is introducing two new small-diaphragm system configurations, the M60 Deluxe Tri-Mono, and M61 Omni Tri-Mono.
Each includes three matched M60 FET microphones with TK61 omni capsules and 40 mm diffuse field spheres. The M60 Deluxe TRI-MONO Set also includes three matched TK60 cardioid capsules.
The three-microphone sets are capable of matched stereo and Decca-tree recording configurations. In combination with additional matched pairs, the configuration is ideal for multi-channel immersive audio capture.
The M60 amplifier, utilizing a proprietary circuit topology, produces is designed to provide exceptional transient response and SPL handling capabilities. The M60 is a re-interpretation of the classic FET mic amplifier, incorporating carefully selected and tested components that are hand-plugged into gold-plated circuit boards. The output is matched with a custom U.S.-made transformer that is designed to offer an especially low self-noise and a stated typical THD+N of 0.015 percent or better.
The three-microphone Decca tree configuration that became popular for classical music recordings in the 1950s utilized three M50 omni microphones positioned in a reverse “T” shape, most often located over the conductor’s head. The most common Decca Tree setup employs three 1-meter bars from which the microphones hang in a triangle configuration; though larger and smaller bar sets can be used.
The capsule assembly of the M50 had a 40mm acrylic sphere, which was actually a “diffuse field sphere” built into the microphones 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 an 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 on axis by the microphone.
