The TELEFUNKEN CU-29 "Copperhead"
TELEFUNKEN Elektroakustik microphones are known for
their beautifully detailed reproduction and historic accuracy. Because TELEFUNKEN
Elektroakustik's Diamond Series microphones are meticulously made
to historic detail with no expense spared, that also makes them rather
expensive for the average small studio or home enthusiast. With this in
mind, the R-F-T Series of microphones was created.
The R-F-T line of tube condenser microphones utilizes American
designed electronics in conjunction with New Old Stock tubes and
standardized parts from overseas manufacturers. While we have not "cut
any corners," we have been able to provide a lower cost alternative to
more expensive microphone systems, without sacrificing the qualities
that you would expect from a TELEFUNKEN Elektroakustik
microphone.
With the CU-29 "Copperhead" we went even further to ensure
quality while working toward the goal of providing TELEFUNKEN
Elektroakustik craftsmanship that just about everyone can afford.
No detail was left unattended. Specific attention was given to
circuit board layout, with countless revisions done to optimize current
flow and directness of traces. Each component was experimented with and
individually selected for the best sonic and electronic qualities.
Lastly, careful attention was put on keeping high impedance lines as
short as possible to maximize efficiency and minimize unwanted noise.
The amplifier found in the R-F-T CU-29 "Copperhead" features a
new proprietary circuit designed around a NOS TELEFUNKEN tube
and a custom output transformer. Being a "cardioid only" microphone,
the CU-29 "Copperhead" employs a single-membrane version of the
large diaphragm capsule used in the AR-51 and AK-47 MkII microphones,
which undergoes rigorous testing in our laboratory prior to
installation. Further quality control is ensured again during final
testing and burn-in of the microphone, all to give you the ease of many
trouble free years of use with your R-F-T microphones.
Sonically, the CU-29 "Copperhead" is a remarkably hi-fidelity
microphone with a "present" but not "harsh" character, with clarity and
detail, but entirely devoid of the "bite" usually found in microphones
in this price range.
The microphone provides a solid and clear low end, without the upper
mid-range frequency bump often found in microphones in this price range.
Instead, it has a delicate and intimate "air" that is usually found
only in microphones many times the price, and because it is not a
"recreation" (or even a variation on a theme) the end result is a
detailed yet unique tone, with character and its own sonic texture.
The CU-29 "Copperhead" was developed from the ground up in our
South Windsor Connecticut facility by our in-house design team and the
aid of some of the industry's most knowledgeable and respected
consultants. If you're interested in the history and the development of
