Telefunken Elektroakustik U48

10 years after the development of the ubiquitous U47, the TELEFUNKEN Elektroakustic U48 was released with one variation to the U47; it had "bidirectional" (figure 8) capability. The bidirectional capability can be very useful in more "ambient" recording environments where the engineer recording the sound does not want to hear as much of the room ambience as might be recorded with an omnidirectional or cardioid pick-up pattern.

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.

Each U48 microphone comes complete with M940 power supply, M840 25’ dual-shielded ACX-7 tube microphone cable, M740 elastic shock mount, FC40 locking flight case and WB40 wooden microphone box.
