The K47 Series 2 is the ideal solution to fix imported microphones that have a harsh, sibilant frequency response. The mic’s output transformer is somewhat unique. We take one apart. Warm Audio wants to delight us with another replica of a classic studio microphone. The K67 is the most widely copied type of capsule – specifically for microphones manufactured in Asia. Despite this, the TLM still manages to have a mostly-linear frequency response. A Solen FastCap coupling capacitor gives you extreme transparency. ... and ±1.5dB in frequency response. The 32mm K67 capsule was replaced with a 34mm CK12 styled capsule which was chosen to compliment the new circuit. The coupling capacitor is an industry favorite Solen FastCap, which was chosen for its transparency. Sale. Microphone Parts RK-67 $0.00 / 0.00 The RK-87 can be used in Cardioid-only microphones, and in multipattern microphones. Some of the holes are blind and establish the “air spring” behind the membrane. For protecting the capsule, the U195 uses a large mesh screening similar to the original Neumann U67 mic along with an internal fine mesh screen. Share 0 Tweet 0 Pin it 0 Fancy +1. Each half of the capsule has a 26mm, center-terminated, gold-plated Mylar diaphragm, mounted with plastic rings onto the brass backplates. The microphone can be used very close to a sound source without the sound becoming unnaturally harsh. For use in a Cardioid microphone, simply connect the front diaphragm and front backplate to the circuit. U67 calibration input frequency response. Unlike the K47, the K67 utilizes a two-piece backplate, allowing the diaphragms to be tuned individually and then matched for equivalent response. Its 25mm diaphragm covers 20 Hz up to 25 kHz, and the 17mm capsule … The demo video are amazing... For a better experience on Gearnews, we recommend JavaScript to be enabled, Source: Dimensions: Height: 6in - Outer Diameter: 1.725in. The frequency response of the cardioid and figure-8 directional characteristics are very flat for frontal sound incidence, even in the upper frequency range. It uses two 34mm backplates, separated by a thin aluminum spacer. Avantone found that full range sources is where the CV-12BLA really shines as its frequency range is balanced across the board. RK-87 Microphone Capsule (Neumann K67/K87 clone) 34mm True Condenser. Neumann/YouTube. Frequency Range: 20Hz - 20kHz. It was introduced by Neumann in 1960 with the intention of replacing the U 47 in Neumann’s product line. The use of a bright K67-style capsule with a flat-response circuit creates a sonic profile that is jarring and harsh. We use the finest K67 replica capsule in the world, as well as the original 6AU6 tube, and a custom replica Sowter output transformer; one that carefully matches the ratio and frequency response of the original. Nonetheless, Neumann staff maintain that the reissue U67 was identical to the original in every way but one — the output connector differed. The RK-67 is a high-quality copy of the Neumann K67, hand-tuned, with front and rear diaphragms matched for frequency response and sensitivity. According to the late Stephen Paul, the reissue U67s suffered from what he characterized as reduced tolerances on the CNC-lathed K67 capsule. From the diaphragm side, there are rows of 6,8,10,12,12,12, 12,12,12,10,8,6. It used a 6.3V filament voltage, and was wired to the PCB via a Teflon socket. 3,041 330. Your email address will not be published. The frequency response is very smooth all the way from 20 Hz to 20 kHz, with only a very small presence bump around 12 kHz. According to Roessler, the tapered body shape was purely a cosmetic change, intended to satisfy an increasingly style-conscious market.
