Alchemy Microphone Series: Audio Comparison

Introducing the Alchemy Microphone Series, TELEFUNKEN Elektroakustik's TEC Award nominated 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 article 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.

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.

The TF29 Copperhead and TF39 Copperhead Deluxe are evolutions of the CU-29 Copperhead, an original TELEFUNKEN Elektroakustik design that garnered fans for its natural and non-hyped tonality and unparalleled “quality for price”. The TF29 and TF39 continue this reputation of outstanding sonic performance and value. They are workhorse microphones, accurately and honestly capturing vocals, acoustic and electric guitar, drums, and nearly any source put in front of them.

The TF39 Copperhead Deluxe is an expansion of the “Copperhead” sound with the addition of a dual membrane K67-style capsule, allowing for 3-pattern selection between cardioid, omnidirectional, and figure-8. This added feature set gives the TF39 greater flexibility and options in the studio.


The TF47 is a new design based on the “German” sound, drawing inspiration from the historic U47 and M49. With a deep low end and a forward midrange, the TF47 is excellent for adding depth and presence to any source. These characteristics make it especially ideal for recording vocals, guitar amps, and drums.


The TF51 is a fresh take on the “Austrian” microphone sound associated with the Telefunken ELA M 251E and C12. The TF51 continues this legacy, exhibiting a smooth midrange and airy top end, capturing every nuance in pleasant detail. This is a reliable first choice for stand out vocals, acoustic instruments, and percussion.
