Telefunken ELA M 251 T

Telefunken introduces the ELA M 251 T, a microphone featuring the CK-13™ capsule. While based upon the classic ELA M 251 models, the ELA M 251 T adds a very modern twist.

The TELEFUNKEN Elektroakustik ELA M 251 T is featuring the new TELEFUNKEN Elektroakustik CK-1 capsule. While based up the classic ELA M 251 models, the ELA M 251 T adds a very modern twist.

That twist is the implementation of Alloy 2213 as the diaphragm membrane material for the CK-13 capsule. Alloy 2213 is an amalgam of Titanium and Aluminum, which was originally developed for the aerospace industry.

Traditionally gold has been sputtered onto Mylar for the diaphragms of the historic CK-12 capsule. By employing Alloy 2213, which is far more rigid than gold, TELEFUNKEN Elektroakustik has developed a capsule that provides greater accuracy in the low frequency ranges of the audio spectrum by attaining a higher damping factor to the motion of the membrane.
TELEFUNKEN Elektroakustik CK-13 Capsule

Alloy 2213 is lighter than gold, and when combined with the edge terminated CK-12 system provides an "airy" and "delicate" representation of the upper ranges of the audio spectrum. This affords the user a higher degree of detail in the recorded sound while still providing the depth of audio for which ELA M 251 microphones have been associated for decades.

After extensive R&D, the perfect diaphragm tuning and fabrication was achieved, resulting in a microphone capsule that can better withstand moisture, smoke, and extreme volume, thus requiring less maintenance over the years, and provides the user a superior capture of the sound to be recorded.

The amplifier is the same as the ELA M 251 E which features a New Old Stock [NOS] TELEFUNKEN 6072a tube, a European-made output transformer, but also can be fitted to the ELA M 251 amplifier which is fitted with a NOS TELEFUNKEN AC-701 tube. The CK-13 capsule assembly will also be available through regular distribution channels for aftermarket retro-fit to all TELEFUNKEN Elektroakustik ELA M 250 and 251 models both new and vintage.

The ELA M 251T also sheds the classic mint green body color of the ELA M 250, 250E, 251 251E & ELA M 270 in favor of a sleek sulfamate nickel-plated finish to reflect the proprietary capsule technology. The ELA M 251 T System comes complete with capsule, amplifier, power supply, and 4-year warranty. Included in the package is a stand-mount cable connector, ruggedly-built power supply, wooden microphone box, and a classic leather bound locking tweed flight case.
