Sound Pure's Take

While not changed as much from the AR51 (as compared to the TF47/AK47), the upgraded power supply and internals will really bring the performance of this mic up a step.  Just like the c12 and 251e, the TF51 really benefits from working the proximity effect to your advantage and getting that pushed sound.  With a controlled midrange and a really open and Airy top end, the TF51 really complements the TF47 well. 

The Alchemy Series:

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.

From TELEFUNKEN Elektroakustik

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.

 

Circuit Design

This lifelike fidelity is created with high quality components based off these inspirations. The 6072A vacuum tube (also found in our ELA M 251E and C12) is mated with an edge-terminated style capsule similar to the historic CK12. The output transformer is a custom German-made Haufe transformer, the original manufacturer for TELEFUNKEN. This attention to detail gives the TF51 a beautifully open and smooth sonic profile.
