While based upon the classic ELA M 251 models, the ELA M 251 T adds a very modern twist. That twist is the implementation of Alloy 2213™ as the diaphragm membrane material for the CK-13™ capsule.

Traditionally gold has been sputtered onto Mylar™ for the diaphragms of the historic CK-12 capsule. By employing Alloy 2213™, which is far more rigid than gold, TELEFUNKEN Elektroakustik has developed a capsule that provides greater accuracy in the low frequency ranges of the audio spectrum by attaining a higher damping factor to the motion of the membrane.

The ELA M 251T also sheds the classic mint green body color of the ELA M 250, 250E, 251 251E & ELA M 270 in favor of a sleek sulfamate nickel-plated finish to reflect the proprietary capsule technology.

Every component in the each of the two TELEFUNKEN ELA M 251T microphones is hand-selected, allowing as close a match as is possible between each system. Capsules are tuned to each other; transformers and tube are tested for matched gain and frequency response. These sets offer the user the knowledge and comfort that the tools they are using will give identical responses for their most important stereo recording.
