The Telefunken ELA M 251 Classic Tube Microphone Stereo Set is a matched stereo pair of Telefunken ELA M 251 tube condenser microphones. The ELA M 251 is regarded as one of the most essential microphones in recording, and is sought after by leading industry professionals, recording studios and artists. The ELA M 251 sits in line with Telefunken's history of quality professional microphones, and its lineage can be traced back to the original Neumann U-47 microphone produced in 1947 (distributed by Telefunken).

The ELA M 251 with the Telefunken AC701 tube, which is soldered into circuit, can be found in countless recordings throughout history. The mic's capsule houses the famous CK12 1" dual-sided gold-sputtered diaphragm, and the switchable cardioid, omnidirectional and figure-8 polar patterns are accessible on the microphone itself.

The ELA M 251 stereo set will allow recording engineers to employ a variety of stereo recording techniques, including X/Y coincidental pairs when utilizing the mics in their cardioid patterns, or A/B-spaced pairs while using the mics in either cardioid or omni. Designed for convenience, the set comes with a dual microphone-capable power supply included. Each component is hand-selected and matched to allow for as close of a match between the two microphones in each system as possible. Capsules are tuned to each other, and transformers and tubes are tested for matched gain and frequency response.
