Diamond Series Microphones

The Diamond Series features microphone models that epitomize vintage vacuum tube microphone technology, which characterize and color the sounds of popular recorded music from the late 1940’s through today. The Diamond Series currently comprises of five microphones; three main models and two variants. All of the parts for these microphones were reverse engineered and recreated exactly to the originals in order to manufacture new models and provide restoration parts for the vintage versions. The large majority of the parts are custom tooled and machined in the USA. Every microphone is hand-built and assembled from the ground up and tested in the TELEFUNKEN facility located in South Windsor, Connecticut.

ELA M 251E

The ELA M 251E is a meticulously accurate reissue of one of the most legendary microphones of all time, featured on countless hits and classic recordings.

ELA M 251 T

Based upon the classic ELA M 251E microphone, but with a modern twist: The 251T utilizes Alloy 2213™ as the diaphragm membrane material instead of gold.


The TELEFUNKEN Elektroakustik recreation of the iconic U47 is exact in every detail, down to the historically accurate BV8 transformer and M7 capsule.


A historically accurate recreation of the legendary U47 variant, the U48 features bidirectional (figure 8) capability, as well as cardioid.


Revered for its smooth and airy frequency response, if there were ever a microphone that was the epitome of classic, hi-fidelity sound, it would be the C12.

ELA M 251 (Discontinued)

Standard production of the AC701 based ELA M 251 has been suspended. Please note that we will continue to produce the 6072a based version, the ELA M 251E.
