The MJE-K47H is a cardioid, large diaphragm capsule head that attaches to popular SDC mic bodies to create a large diaphragm mic with robust, midrange-rich timbre. Record sibilance-free vocals, punchy acoustic guitar tracks and big-sounding drum overheads.

The MJE-K47H fits small diaphragm mic bodies with model numbers 603/604, 991, CM-54, CM-90, 1200, 180/185, 404, v67n and SC-1 etc with 22 mm body diameter and tapered XLR connector - NOTE: Does not fit Oktava MK-012 body. I am working on a version for the '012 mic body, stay tuned!

The K47 capsule used in the U 47 and other classic Neumann mics is one of the most revered large diaphragm capsules ever made - its spectral response provides rich upper bass, very low phase shift mids and a gentle presence "mound" followed by a natural, sibilance-free top end. Some of the greatest vocal tracks of all time were cut with talent singing into a K47 capsule. You can get that magic today with my version - the MJE-K47H capsule head.

"The MJE-K47H is my new favorite amongst some very tough competition...extraordinarily clear, balanced signal... notably true-to-life." Michael Vecchio, The Deli (review) , 11/09

MJE-K47H "Solo" NOTE: The "Solo" is one MJE-K47H in a paperboard box.
Order the "Mono" if you want one MJE-K47H and a shock mount in an aluminum case that also holds your SDC body and capsule.
Year-long R&D

The new MJE-K47 capsule is the result of my painstaking search to find a specialized capsule manufacturer that could produce a K47-type capsule to my exacting specifications for timbre voicing, electro-acoustical performance, quality control and price. The MJE-K47 capsule tracks an actual K47 capsule response within +/- 1.5 dB across its operating range for true-to-original fidelity. Every MJE-K47 capsule is individually tested in a large anechoic chamber and its frequency response plotted. Every MJE-K47H capsule head is supplied with the individual capsule's response plot.

The MJE-K47H headbasket design is the result of my long term research into headbasket acoustics. The headbasket uses a classic, non-parallel shape to avoid standing wave coloration and features my signature single-layer grille design for maximum acoustic transparency - you'll hear detailed resolution along with fast and accurate transient response. The dimensions of the headbasket were chosen to provide an extra touch of the lower-midrange presence you look for in a K47-type mic.

Capsule Head Innovation

The MJE-K47H capsule head employs a unique “body cone” that creates a secure fit between capsule head and pencil mic body – the mic body is recessed well up into the capsule head and is held securely by both the capsule head threads and the body cone’s friction fit. The body cone has an internal rubber fitting that prevents marring the surface of the pencil mic when it is screwed into the capsule head.

The body cone also acts as a shock isolation barrier to reduce transmission of mechanical noise to the capsule. These innovative and unique features make the MJE-K47H the most advanced capsule head design available today.

Every MJE-K47H capsule head is individually assembled by hand and personally tested by me in my studio and lab in Springfield, Massachusetts. Each capsule head comes with a signed and dated Certificate of Performance that includes the capsule’s individual anechoic chamber frequency response curve.

Consistent with my strategy of providing cost-effect upgrade paths for recordists, the MJE-K47H capsule head allows you to grow your microphone locker sensibly and economically – by adding a large diaphragm capsule head to the small diaphragm mic you already own.
