TELEFUNKEN Elektroakustik microphones are known for their beautifully detailed acoustic reproduction. As they're made in a 'no holds barred' manner, that also makes them rather expensive for the average small studio or home enthusiast. With this in mind, the R-F-T series of microphones was created.
This new line of tube condenser microphones utilizes American designed electronics in conjunction with New Old Stock tubes and standardized parts from overseas manufacturers. While they have not "cut any corners," they have been able to provide a lower cost alternative to more expensive microphone systems, without sacrificing the qualities that you would expect from a TELEFUNKEN Elektroakustik microphone.
The amplifier found in the R-F-T AK47 features a new proprietary circuit designed around a NOS TELEFUNKEN EF-732 tube and a custom output transformer built in the good ol' U.S. of A. The dual sided large diaphragm capsule undergoes rigorous testing in their laboratory prior to installation in the R-F-T AK-47, and again during final testing and burn-in of the microphone.
Sonically, the R-F-T AK47 is a remarkably hi-fidelity microphone with a "present" but not "harsh" character, which in many ways is reminiscent of a historic M-49. The TELEFUNKEN EF-732 tube is very similar to the AC-701 tube in that is provides a "velvety" character to the overall tone of the microphone. When this tube is coupled with their custom designed output transformer the result is a microphone with superior high frequency detail, a rich and thunderous low end, without the upper mid-range frequency bump (what many call "guitar store brightness") often found in microphones in this price range. Instead, it has a delicate and intimate "air" that is usually found only in microphones three times the price.
