Telefunken U48 Microphone Stereo Set Large Diaphragm Tube Condenser Microphone

TELEFUNKEN Elektroakustik is proud to offer matched stereo sets of the U48 microphones. Each system features a custom dual power supply capable of powering both microphones at one time, and a special locking flight case that will carry both sets of microphones, cables, wooden boxes, and the dual power supply. In keeping with the long standing tradition, TELEFUNKEN Elektroakustik have given a nod back to 1958 when both the U47 and U48 were offered in 3 unique packages. The U47 and U48 were both offered in what was called a "Stereo Set" that featured a sequentially serial numbered pair of U47 or U48 microphones with a dual [two microphone capable] power supply, and the "Studio Set," which was a single U47 that was matched to a U48.

The TELEFUNKEN U48 Stereo Set will allow versed recording engineers a variety of stereo recording techniques, including X/Y coincidental pairs when utilizing the mics in their cardioid patterns, or A/B spaced pairs. The option of a Blumlein pair is also available with both microphones set to figure of 8, as well as the traditional M/S (mid / side) technique when using one mic in cardioid and the other in figure of 8. Every component in each of the two TELEFUNKEN U48 microphones is hand-selected, allowing as close a match as is possible between each system. Capsules are tuned to each other; transformers and tube are tested for matched gain and frequency response. These sets offer the user the knowledge and comfort that the tools they are using will give identical responses for their most important stereo recording.

FEATURES

• Sonic Characteristic
  - According to the book Recording The Beatles, the U48 was one of George Martin's favorite microphones when actually "recording The Beatles". Utilizing the same M7 capsule, BV8 output transformer and VF14K vacuum tube as TELEFUNKEN’s historic reissue of the U47, the U48s authoritative mid-range and extended low-end response make the microphone an excellent tool for recording vocals and acoustic instruments, both near and far.
  
  
• Circuit Design
  - Since its original development in the late 1950s, the TELEFUNKEN U48 has been the microphone of choice for generations of recording professionals. The original U48 also featured the famous M7 capsule which had been developed in 1928 by Georg Neumann. To this capsule was added an amplifier built from military surplus VF14 tubes (they had been used in field and aircraft radios), and BV8 output transformers. The combination of these components created a sonic quality that was absolutely unheard of in the English speaking world of the mid-1940s when darker sounding, less detailed ribbon microphones were the standard.
  
  
• Construction
  -The large, chrome headgrille houses a newly manufactured M7 capsule. Its matte nickel finished body houses a new BV8 output transformer and a newly developed VF14k vacuum tube; a "plug and play" replacement for the rare VF14M tubes found in the original. The classic "TELEFUNKEN" diamond logo proudly adorns the front of the body tube.
