ELA M 251T

TELEFUNKEN Elektroakustik presenta el nuevo ELA M 251T, un micrófono con la recién desarrollada cápsula CK-13™. Aunque basado en los modelos clásicos ELA M 251, el ELA M 251T añade un toque muy moderno. Ese toque es la implementación de Alloy 2213™ como material de membrana de diafragma para la cápsula CK-13™. Alloy 2213™ es una amalgama de titanio y aluminio, originalmente desarrollada para la industria aeroespacial.


Sonic Characteristic
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, the capsule that provides greater accuracy in the low frequency range by attaining a higher damping factor to the motion of the membrane. Alloy 2213™ is lighter than gold, and when combined with the edge terminated CK-12 system provides an “airy” and “delicate” representation of the upper frequencies. This affords the user a higher degree of detail in the recorded sound while still providing the depth of audio for which ELA M 251 microphones have been associated for decades.

Circuit Design
The TELEFUNKEN ELA M 251T includes an edge terminated, dual backplate CK13 capsule, a variation of the traditional CK12. The 251T is capable of cardioid, omnidirectional and bidirectional polar patterns, just like the ELA M 251E. The amplifier circuit features a premium New Old Stock ECC801S vacuum tube and a Haufe T14/1 output transformer, the same found in the 251E and C12.

Though the 251T shares the same basic vintage-accurate construction of the 251E, it is wrapped in a sleek sulfamate nickel-plated finish to reflect the proprietary capsule technology.

Each ELA M 251T microphone comes complete with M 950T power supply, M 850T 25′ Sommer tube microphone cable, Rycote shockmount, FC50 locking flight case and WB50 wooden microphone box.
