San Francisco, October 27, AES Convention 2012 — TELEFUNKEN Elektroakustik of South Windsor, CT is introducing stereo sets of microphones from its popular and affordable R-F-T series of large diaphragm vintage tube microphones at AES 2012.

The AR-51, AK-47mkII, and CU-29 microphone systems, now being offered in matched stereo sets, feature a custom dual power supply capable of powering both microphones at one time, as well as a locking flight case that contains both microphones, cables, shock mounts, and wooden mic boxes. All the electronic components in each system are matched sonically and electronically, including matched capsules, transformers, and vacuum tubes.

AR-51 Stereo Set
The R-F-T AR-51 was designed to incorporate the amplifier circuit of the C12 and ELA M 251E into a more affordable package than its Diamond Series counterparts. This circuitry has been a favorite for hi-fidelity stereo pair recordings for decades. TELEFUNKEN Elektroakustik has taken this classic sound and developed the AR-51 Stereo Set.

The result is a vintage sounding microphone with a smooth mid-range, open top end, and a solid, well-balanced low frequency translation. The AR-51's distinct character is great on anything from vocals to drums to acoustic guitar to saxophone. With a matched pair of AR-51's, several stereo recording techniques can be executed for any source from drum overheads, acoustic guitars, piano and percussion to larger sources such as orchestras, choirs, and large chamber groups.

AK-47 MkII Stereo Set
The R-F-T AK-47 MkII began as a unique design to incorporate key elements of classic circuits such as the U47 and M49. These design decisions created a microphone with a rich and warm low-mid frequency response ideal for vocals, bass (acoustic and electric), brass instruments, and drums. With these applications in mind, TELEFUNKEN Elektroakustik has developed the AK-47 MkII Stereo Set. The AK-47 MkII is a uniquely voiced microphone with superior high frequency detail and rich low-end qualities. The Stereo Set lends itself to a wide array of stereo recording applications.

CU-29 Copperhead Stereo Set
Since its introduction, the R-F-T CU-29 Copperhead has proven itself equally useful on vocals, acoustic instruments, guitar amps, and drums. The amplifier in the CU-29 Copperhead features a new old stock TELEFUNKEN 6AK5W vacuum tube, Lundahl LL1935 output transformer, and a single-membrane version of the large diaphragm capsule used in the AR-51 and AK-47 MkII.
Sonically, the CU-29 Copperhead is a hi-fidelity microphone with a present but not harsh character. The microphone provides a warm, clear low end complemented by a smooth high end, with a delicate and intimate air to it.
