Product Description

This is the stereo, factory matched pair.

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 vacuum tubes and standardized parts from overseas manufacturers. Just like the Diamond Series, all R-F-T microphones are hand-built in our South Windsor, CT facility. With this line, 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. Extra consideration was put on keeping high impedance lines as short as possible to maximize efficiency and minimize unwanted noise. Lastly, a wide array of output transformers was experimented with to provide the most open and sonically pleasing response.

This fine-tuned amplifier design found in the R-F-T CU-29 "Copperhead" features a NOS 6AK5W TELEFUNKEN tube and a Lundahl LL1935 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 upper mid-range bite usually found in microphones in this price range.

The microphone provides a warm, clear low end complemented by a smooth high end, with a delicate and intimate "air" to it, typically found only in microphones many times the price. Because it is not a "re-creation" (or even a variation on a theme) the end result is a detailed yet unique tone, with character and its own rich 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.

The CU-29 "Copperhead" delivers top shelf TELEFUNKEN Elektroakustik quality at a price nearly any dedicated engineer, musician, or enthusiast can afford.
