Sound Pure's Take

Telefunken USA is known for making the premier vintage mic reproductions, and the Copperhead is the TFunk making a mic versatile and affordable enough for the masses but without sacrificing the opulence and musicality you've come to expect from TELEFUNKEN Elektroakustik.

The Copperhead's flat response is really what sets this mic apart from almost every other mic in this price point.  We love how natural and smooth the top end is on this mic, you just don't get any of the "harsh" or "brash" top end nastiness that is an epidemic in many mics at this price point and lower.  We've used the Copperhead on just about everything in our studio, from Vocals to Acoustic guitars, Drum Overheads to Electric guitar and even our Steinway, the Copperhead really performs very well across all of these sources.  You hear this all the time, we know, but because the frequency response is close to flat with the copperhead, you can use it on almost any source.  This mic doesn't oversaturate, it doesn't have huge dips and spikes across the frequency range; it captures the source, and it does it very well for the price.

If you are looking for a mic that has a lot of color and tone, or a mic that will take your vocal and change it into something else, this might not be the mic for you.  But if you are looking for that studio workhorse, that mic that you can safely put on any source and rely on getting a great recording, the CU-29 Copperhead is for you.

From TELEFUNKEN Elektroakustik

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.

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