Telefunken TF51 Stereo Set

Large diaphragm tube condenser microphone based on the specifications of ELA M 251E and C12 – Stereo Set Version

TELEFUNKEN Elektroakustik is proud to offer matched stereo sets of the TF51 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.

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 TF51 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. 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 cardiod and the other in figure of 8. The custom M 910S dual-microphone power supply offers nine polar patterns for each microphone making the options of stereo microphone techniques nearly infinite.

Every TF51 Stereo Set system comes with two sonically matched microphones, a variable pattern dual M 901S Power Supply, (2x) M 803 Tube Microphone Cables, (2x) M 703 Elastic Shock Mounts, (2x) Microphone Sleeves, and a Locking Flight Case. All the electronic components in each system are matched sonically and electronically, including matched capsules, transformers, and vacuum tubes.
