Cardioid Tube Condenser Microphone
The E47C was the second-generation short-body U47 recreation from David Bock and Soundelux. The original E47 (no ‘C’) could be switched into multipattern mode, enabling a continuously-variable pattern-selection dial on the power supply. The E47C had no such option, due to feedback from the user community that the E47 was most commonly used in cardioid mode anyway.
The mic used a NOS Telefunken EF814 tube, hand-selected by Soundelux.
The E47C uses an NOS Telefunken EF814k tube situated in a shock-mounted ceramic socket. (The suffix “k” is added after selection, burn-in and testing of the tube at the Soundelux factory in Los Angeles.) The EF814 is a large plate… pentode tube (wired as a triode) that’s very close in characteristics to the original U47’s “out of print” VF-14 tube. Soundelux located and procured a huge supply of EF814ks in Europe, so the company is well-stocked for the future.
(With the untimely demise of Soundelux, David Bock’s warehouse of EF814s has found a home in the new Bock Audio 507, which like the E47 utilizes a preamp circuit based on the U-47.)
Although cardioid-only, the E47C retained the dual diaphragms of its predecessor. The reviewer from MIX noted “after years of close vocal use, you can just flip the capsule around instead of replacing it.”
The Soundelux E47C is also known as: E-47C.
The mic was released in 2005.
