Peluso 22 47 Vacuum Tube Microphone
The Peluso 22 47 is a large diaphragm condenser microphone styled after the legendary Neumann U 47 microphone. German radio engineers in the 1970's needed to lower the noise floor of their trusted U 47 microphones to conform to broadcast standards of the day. To achieve this, the microphones were re-wired to employ the new glass 6072A tube. The Peluso 2247 uses this glass triode tube achieve its high gain and low noise floor. The capsule, components and transformer are the same as those found in our steel tube 22 47 models. While many seek out the musical second harmonic content found in the steel tube mic, others prefer the cleaner and slightly quieter quality of the glass 6072A tube found in this 22 47 (short-body) model. Whichever 22-47 microphone you select you will find incredible detail coupled with the smooth warmth the '47 name is known for.
The 22 47 is paired with the Peluso MX-56 power supply. The dual sided capsule in the 22 47 enable the power supply to feature 9 polar patterns in an array from omni-directional to cardioid to figure eight.The 22 47 features our heavy-duty 8-pin screw on cable connector. The large diameter pins in the screw on connector give a tight and secure cable connection designed to perform for a lifetime of us
Acoustically matched pairs available upon special request.

Comparing the 22 47, 22 47 LE and 22 47 SE:
All of the microphones in our 22 47 line are styled after the vintage Neumann U 47. This legendary microphone was revered for its clear sound, smooth and warm mid range, balanced high end and great body. Neumann discontinued U 47 production when Telefunken ceased production of its metal VF 14 tube. Our 22 47 LE model is supplied with a German vintage steel tube from this era. We have worked for years to acquire and test a generous supply of these rare tubes. We are proud to offer a microphone with this true vintage tube. With our 22 47 SE model we are able to offer the same sonic quality with an American style metal tube. These tubes are available to us in larger quantities. This allows us to provide the sonic qualities of a ‘47’ microphone with a lower price. The only discernible difference in sound between these two models is a 2 dB quieter noise floor on the SE model. In the 1970’s German radio broadcast engineers began modifying their then-vintage U 47’s to incorporate a new glass triode tube. The new glass triode tube provided a very quiet noise floor, and has less of the complexity and second harmonic content than the steel tubes provided. The Peluso 22 47 model is based on this glass tube modification. Carefully selected components, thorough testing, and attention to detail all come together making these some of our most popular microphones.
'On vocals and acoustic guitar we prefer the 22 47 up close because it creates a sense of stunning intimacy. The proximity effect becomes obvious, but you can dial the response towards the omni setting and the sound smoothes out in the low end, gaining a bit of high-frequency sparkle in the process.'
