Telefunken U47 Stereo Set

TELEFUNKEN Elektroakustik is proud to offer matched stereo sets of the Telefunken U47 Stereo Set 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.

TELEFUNKEN Elektroakustik is proud to offer matched stereo sets of the U47 microphones.

Every great singer deserves an amazing microphone, and for more than 60 years the U47 has been that microphone. Its authoritative mid-range and extended low-end response have made the TELEFUNKEN U47 the “go to” standard for any serious recording studio. Everything, from vocals and loud guitar sounds to full on orchestral recording and chamber ensembles, will benefit wildly from the rich and vibrant tone of this stunning microphone. The TELEFUNKEN Elektroakustik recreation of the U47 large diaphragm tube microphone is exact in every detail, down to the historically accurate BV8 output transformer and M7 capsule.

Every component in each of the two TELEFUNKEN U47 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.

Stereo microphone techniques are often used for recording classical music and large signal sources like orchestra, choirs, and large chamber groups. They can also effectively be used on drum overheads, acoustic guitars, piano, and percussion. The TELEFUNKEN U47 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 while using the mics in either cardioid or omni.

Each Telefunken U47 Stereo Set STEREO SET comes complete with a dual M940S power supply, 2x M840 25′ dual-shielded ACX-7 tube microphone cable, 2x WB40 wooden microphone boxes and a FC10 locking flight case.
