Telefunken Elektroakustik R-F-T AK47 MKII Tube Condenser Microphone #2258 (Used)

Product Description

The Telefunken Elektroakustik R-F-T AK-47 MkII is a large diaphragm tube condenser microphone with a 9-way pattern selection switch on the power supply. Its amplifier features a proprietary circuit designed around a NOS Telefunken EF-732 tube and a custom output transformer that is for all intents and purposes an EXACT replica of the historic BV8 transformer found in historic U-47 and U-48 microphones. The dual sided large diaphragm capsule undergoes rigorous testing in the laboratory prior to installation in the R-F-T AK-47 MkII, and again during final testing and burn-in of the microphone.

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 the historically accurate recreation of the BV8 transformer some of the magic begins. In addition, 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) as well as a layout, which minimizes noise and cross talk between components.

Sonically, the R-F-T AK-47 MkII is a remarkably hi-fidelity microphone with a "present" but not "harsh" character, which in many ways is reminiscent of a cross between the historic M-49 and U-47/48 microphones of yesteryear. The result is a microphone with superior high frequency detail, a rich and thunderous low end, without 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 only in microphones three times the price.
