The R-F-T AK-47 MkII is a remarkably hi-fidelity microphone that is reminiscent of a cross between the historic M49 and U47 / U48 microphones. The result is a microphone with superior high frequency detail and a rich, full low-end response.
TELEFUNKEN Elektroakustik is well known for the historic recreation microphones found in the Diamond Series, which are meticulously made to historic detail with no expense spared. As such, these microphones become rather expensive for the average small studio or home enthusiast. With this in mind, the R-F-T Series of microphones was created.
The R-F-T Series of tube condenser microphones utilizes American designed electronics in conjunction with New Old Stock (NOS) vacuum tubes and standardized parts from overseas manufacturers. Just like the Diamond Series, all R-F-T Seriesmicrophones are hand-built in TELEFUNKEN Elektroakustik's South Windsor, Connecticut facility. With this line,TELEFUNKEN Elektroakustik is able to provide a lower cost alternative to more expensive microphone systems, without sacrificing the qualities that would be expected from a TELEFUNKEN Elektroakustik microphone.
The amplifier found in the AK-47 MkII features a new proprietary circuit designed around a NOS EF-732 / 5840W vacuum tube, and a custom output transformer that is an exact replica of the historic BV8 transformer found in new TELEFUNKEN Elektroakustik and vintage U47 and U48 microphones. The dual sided large diaphragm TK67D capsule undergoes rigorous testing in our laboratory prior to installation in the AK-47 MkII, and again during final testing and burn-in of the microphone.
The EF-732 / 5840W tube is very similar to the legendary AC-701 tube in that is provides a velvety character to the overall tone of the microphone. The layout of the circuit board features broader traces for superior current on demand capability, which enhances the low frequency and transient response capability of the amplifier. Additionally, this layout helps minimizes noise and cross talk between components. When this tube and circuit is coupled with the historically accurate recreation of the BV8transformer, the AK-47 MkII reproduces the qualities of the classic microphones it was based upon.
Sonically, the AK-47 MkII is a remarkably hi-fidelity microphone with superior high frequency detail and a rich, thunderous low end that excludes the upper mid-range frequency bump often found in microphones in this price range. Instead, it has a delicate and intimate air that is usually found in more expensive microphones. The AK-47 MkII serves as a great microphone for vocals, electric guitar, acoustic and electric bass, and horns.
The remote pattern selector, located on the power supply, provides 9 different polar patterns, giving the user a myriad of choices for how to record the source sound in a manner that will best complement their production.
Each AK-47mkII microphone comes complete with M901 power supply, M801 25' dual-shielded TX-7 tube microphone cable,M701 elastic shock mount and wooden microphone box.
The AK-47 MkII Stereo Set offers the user the knowledge and comfort that the tools they are using will give identical responses for their most important stereo recording.
Each AK-47mkII Stereo Set comes complete with an M901S dual power supply, 2x M801 25' dual-shielded TX-7 tube microphone cables, 2x M701 elastic shock mount, 2x wooden microphone boxes and an FC10S locking flight case.
