Telefunken ELA M260 Condenser Microphone Tri Mono Recording Set

Set of Three Small diaphragm Tube Condensor Microphones

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.

Engineers who recorded classical music for Decca Records pioneered the Decca Tree (or “Tri-Mono”) 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-MonoRecording 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 madetwo 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 thetransduction capsule. The result is a gradual and smooth rise in upper midrange and high frequency information captured by the microphone.

All ELA M 260 TRI-MONO SETS are supplied with two sets of three interchangeable capsules: the TK60cardioid, TK61 omni, and TK62 hyper-cardioid. With all three capsules the user can have the flexibility to record their source material in any way they wish. Each system also includes a M963  triple power supply, 3x M801 25’ dual-shielded TX-7 tube microphone cable, 3x M761 elastic shock mount, 3x wooden microphone boxes and locking flight case.
