It used a 6.3V filament voltage, and was wired to the PCB via a Teflon socket. The coupling capacitor is an industry favorite Solen FastCap, which was chosen for its transparency. Dimensions: Height: 6in - Outer Diameter: 1.725in. Neumann reportedly produced a reissue of the U67 sometime in the late 1980’s or early 1990’s. The RK-47 is an affordable upgrade or replacement to fix imported microphones that have a harsh, sibilant frequency response. Please let us know! We are proud to announce the RK-47, a true single-backplate dual-diaphragm microphone capsule modeled after the legendary K47. For multipattern operation in a 4-wire circuit (such as the U87i), connect both front and rear diaphragms, and both backplates independently. According to David Bock, “it uses a tertiary winding for negative feedback through the capsule to the tube.”. Nonetheless, Neumann staff maintain that the reissue U67 was identical to the original in every way but one — the output connector differed. Neumann/YouTube. The mic’s output transformer is somewhat unique. Frequency Response. It uses two 34mm backplates, separated by a thin aluminum spacer. It’s also a great choice for DIY builds of the U47, 47 FET, and others. It’s known for an aggressive midrange and high end with a peak around 5kHz as well as a high frequency peak around 12-13kHz. The microphone can be used very close to a sound source without the sound becoming unnaturally harsh. It’s a solid brass dual backplate, dual membrane of a somewhat similar design to the CK12. Related Products. Well, $75 is less than 1/3 of the price of many replacement capsules. 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. The RK-87 can be used in Cardioid-only microphones, and in multipattern microphones. Amazing! It’s also a suitable choice for … If you continue surfing the site, you agree to the, Sony C-100 dual-capsule condenser microphone hits markets, NAMM 2019: Blue introduces USD 99 Ember condenser microphone, AES 2017: Earthworks debuts premium SV33 condenser microphone, sE ships mid-priced sE2300 multi-pattern condenser studio microphone, Apple M1X chip with 12 CPU cores and 16 GPU cores gets wild benchmark results, GForce OB-E: Oberheim 8-Voice synthesizer in stunning octaphonic detail. 34mm Capsule Large Diaphragm Condenser Microphone Replacement Circuit Board DIY. Sale. A -10dB pad was incorporated, in response to the trend of placing microphones closer to sources. Frequency Range: 20Hz - 20kHz. Capsule Type: Gold Sputtered 34mm K67 style. The Neumann U 67 is also known as: U 60, U67. In addition, the PCB uses gold traces for better conductivity. The Neumann manual gives a 100Hz corner frequency, but the published graphs show attenuation as high as 300Hz. 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. The cardioid characteristic maintains a smooth frequency response at a distance of 30 to 40 cm, … The published frequency-response graphs are much flatter through the high frequencies than is normally the case with K67-based condenser microphones. According to the late Stephen Paul, the reissue U67s suffered from what he characterized as reduced tolerances on the CNC-lathed K67 capsule. The tube is a subminiature 6205 pentode, branded Groove Tubes GT6205 in the MIX magazine review sample, and is reportedly wired as a triode. Weight: 346g I hope they maintain the Oberheim quality and versality that I love so much. RK-87 Microphone Capsule (Neumann K67/K87 clone) 34mm True Condenser. Each RK-47 capsule is individually tested in an anechoic chamber prior to shipping, to ensure that its frequency response meets our standards. This is the most-copied capsule design in the world, since the original K67 is the capsule of the famous U87 and U67. Its 25mm diaphragm covers 20 Hz up to 25 kHz, and the 17mm capsule … The Dachman Audio K47 Series 2 mic capsule is a replica of the famous K47 mic capsule used in the Neumann U47 and U47 FET microphones. Omnidirectional Did we get anything wrong on this page? The first capsule mentioned in the original post is only $75, with mounting hardware, and is described as having "a frequency response within 2 db of the NeumannK47 mylar capsules used in all U47 tube microphones built after 1961." Unlike the K47, the K67 utilizes a two-piece backplate, allowing the diaphragms to be tuned individually and then matched for equivalent response. A Solen FastCap coupling capacitor gives you extreme transparency. Despite this, the TLM still manages to have a mostly-linear frequency response. U67 calibration input frequency response. How is the most popular large diaphragm mic capsule built? Seller 100% positive. $169.00 + shipping. The K67 capsule, which since 1960 has become the most common and most copied condenser capsule in the world, was designed to avoid the challenges and costs of tuning the K47 so that both diaphragms produce identical frequency responses.
