The TELEFUNKEN ELA M 251T
TELEFUNKEN Elektroakustik introduces the new ELA M
251 T, a microphone featuring the new TELEFUNKEN Elektroakustik
CK-13™ 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.
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.

Manufacturing
Recreating a Legendary Microphone
"Built
to a standard, not to a price."
The manufacturing process for Telefunken
products is
complex. Our R&D efforts have led us to
the conclusions
that we should do things the old fashioned
way. We avoid
cutting corners, in favor of recreating each
piece of
the classic design. Telefunken USA utilizes
original
manufacturing processes in order to match
original manufacturer
specifications.
These images demonstrate
several
steps in our manufacturing process.
