What We Think

Built side-by-side with "the big boys" (251E, C12, and U47), the Alchemy Series is the next generation of affordable microphones from TELEFUNKEN Elekroakustik. This series directly replaces (and outperforms!) the older and discontinued RFT line. The biggest changes are subtle, but they really add up when talking about overall performance and reliability. Throw in the fact these mics are now shipping with a flight case (previously an add on), and you have a truly exceptional package.

While you can't see it (but you'll hear it!), one of the aspects we are most excited about is that the mics (capsules and electronics), as well as the power supply (internals), are all "stuffed" in-house, in Connecticut. This undoubltely adds a big level of quality control to the microphone set.

Alchemy Microphone Series Comparison

Introducing the Alchemy Microphone Series, TELEFUNKEN Elektroakustik's next generation of large diaphragm tube condensers. These microphone models feature unique sonic profiles developed from the ground up at Telefunken's American facility with vintage circuitry, modern fidelity, and superior reliability in mind. In this video we will be comparing the distinct voices of the Alchemy Microphone Series; the "Copperhead" sound of the TF29 and TF39, the "German" voiced TF47, and the "Austrian" voiced TF51. Drum Overhead - 00:45 Electric Bass Amp - 01:34 Acoustic Guitar - 02:30 Electric Guitar Spacey Effects - 03:20 Electric Guitar Driven - 04:26 Piano - 05:03 Male Vocals - 05:55 Female Vocals - 06:52 Every source was recorded in mono with each microphone in cardioid configuration. All three microphones were recorded through our API 1608 console direct in to a Digidesign 192 at 24Bit/48K and captured via Pro Tools HD. NOTE: For the purposes of this comparison, only the TF39 Copperhead Deluxe was used to represent the "Copperhead" sound. The TF29 and TF39 in cardioid exhibit the exact same characteristics.

TELEFUNKEN Elektroakustik

About Manufacturer

TELEFUNKEN Elektroakustik of South Windsor, CT has been following the tradition of excellence and innovation set forth by the original TELEFUNKEN GmbH of Germany that began over 100 years ago.

TELEFUNKEN Elektroakustik's origins began in 2000 when owner Toni Fishman acquired the rights to the name and diamond logo for use in North America. The company began with the reverse engineering of a single microphone part: the ELA M 251 polar pattern selector. Mr. Fishman purchased an original Telefunken ELA M 251 for use in his recording studio, but when he received it he discovered that the polar pattern switch was no longer functional. Realizing that this was a common issue with the original units, the idea to recreate it was born.

The switch was reverse engineered and brought into production for other 251 owners with the same issue. With one part down, the goals were set high to successfully reverse engineer the entire microphone exactly as it was originally manufactured. The next two years were spent developing each and every part of the microphone right down to every detail. Numerous original documents and drafts from TELEFUNKEN and AKG were acquired, and coupled with thorough reverse engineering the ELA M 251 was brought back to life with meticulous accuracy.

As TELEFUNKEN moves forward, one foot is rooted in the rich history of the brand, and the other in new microphone innovations. TELEFUNKEN has evolved exponentially from a single pattern switch to one of the industry leaders in top quality microphones.
