Manufacturer's Description from TELEFUNKEN

If you work in film scoring or classical recording, then you should know what a Decca Tree is. If you don't work in those disciplines, here is a brief synopsis of the Decca Tree [or "Tri-Mono"] recording technique.

Engineers who recorded classical music for Decca Records pioneered this microphone placement technique in the early 1950s when they wanted a strong sense of stereo image and balanced coverage of an orchestra, as the conductor might have heard while he led the orchestra.

The technique features three omni-directional microphones placed in a reverse "T" configuration, roughly above the head of the conductor. The "left" and "right" are positioned behind the conductor while the "center" microphone hangs in front of the conductor.

In addition to orchestral recording applications, the Decca Tree configuration can be an invaluable component to more contemporary recordings for drum applications and to gain an overall "band in a room" kind of atmosphere to your recording process. 

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.

The microphone most commonly employed for this technique is the Neumann M-50, though other microphones like the Neumann KM-53's and Schoeps M-221b microphones have been successfully employed. One of the problems often associated with the application of the Decca Tree technique is a loss of high frequency content due to the physics of how sound travels. The greater the distance a sound has to travel, the more high frequency information is lost due to the resistance of the air through which the sound must travel. Another problem that can be associated with this technique can be the capture of greater reverberant information than is often desired (due to the omni-directional capsules employed). The capsule assembly of the Neumann M-50 featured a 40mm acrylic sphere which was actually a "diffuse field sphere" built into the M-50's capsule assembly. In order to obtain a best of both worlds scenario, TELEFUNKEN Elektroakustik has created diffuse field spheres as an accessory for the ELA M 260 Tri-Mono Recording Set.

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. TELEFUNKEN Elektroakustik has made two different sized diffuse field-recording spheres available for the ELA M 260 series of microphones: 50mm and 30mm. 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.

The sphere increases the directionality of an omni-directional capsule by altering the acoustic surface area of the capsule to nearly infinite. Where an omni-directional microphone has (for all intents and purposes) 360° pickup capability, with the addition of a sphere, the frequency response of the microphone is increased in the 2 - 10kHz region of the audio by as much as 2.5 db in the front of the microphone (50mm sphere) while being simultaneously diminished by about 2.5db from 5kHz up from the rear of the microphone. The 35mm attachment gives a less pronounced effect, which may be preferable for smaller venues. This high frequency increase in the front of the microphone coupled with the decrease of upper frequency information from the rear of the microphone increases the perceived directionality of the microphone, while information coming from 90° and 270° remains unaffected. This increased directivity of the microphone, coupled with the rise in high frequency information permits better pickup at a greater distance from the sound source. 

The TELEFUNKEN Elektroakustik TRI-MONO package for the ELA M 260 system consists of three ELA M 260 microphones [finished in black], a 3-channel power supply capable of powering all three microphones, three elastic shock mounts, and a set of three 10-meter AccuSound TX-7 tube mic cables with right angle XLR connectors. In order to foster an element of creativity, all three capsule systems [TK60 cardioid, TK61 omni-directional, and TK62 hyper-cardioid] are included in the package, along with a set of three 50mm and a set of three 30mm diffuse field spheres.

About Manufacturer

TELEFUNKEN Elektroakustik of South Windsor, CT has been following the tradition of excellence and innovation set forth by the original TELEFUNKEN GmbH of Germany that began over 100 years ago.

TELEFUNKEN Elektroakustik's origins began in 2000 when owner Toni Fishman acquired the rights to the name and diamond logo for use in North America. The company began with the reverse engineering of a single microphone part: the ELA M 251 polar pattern selector. Mr. Fishman purchased an original Telefunken ELA M 251 for use in his recording studio, but when he received it he discovered that the polar pattern switch was no longer functional. Realizing that this was a common issue with the original units, the idea to recreate it was born.

The switch was reverse engineered and brought into production for other 251 owners with the same issue. With one part down, the goals were set high to successfully reverse engineer the entire microphone exactly as it was originally manufactured. The next two years were spent developing each and every part of the microphone right down to every detail. Numerous original documents and drafts from TELEFUNKEN and AKG were acquired, and coupled with thorough reverse engineering the ELA M 251 was brought back to life with meticulous accuracy.

As TELEFUNKEN moves forward, one foot is rooted in the rich history of the brand, and the other in new microphone innovations. TELEFUNKEN has evolved exponentially from a single pattern switch to one of the industry leaders in top quality microphones.
