AK-47 MkII

The TELEFUNKEN AK-47 MkII is a large diaphragm multi-pattern vacuum tube microphone that has been designed around a sub-minature pentode tube and a large format output transformer. Reminiscent of a cross between the historic M49 and U47, the AK-47 MkII is a microphone with superior high frequency detail and a rich, full low-end response, suitable for vocals, guitar amps and drums.

Sonic Characteristic

Sonically, the AK-47 MkII is a remarkably hi-fidelity microphone with a "present" but not "harsh" character, a forward mid-range, and a detailed low end response. Designed to take the punch of the heavy sound pressure level of a guitar amp or kick drum, it still has a delicate and intimate air that is usually found in more expensive microphones.

Circuit Design

The amplifier found in the AK-47 MkII features a new proprietary circuit designed around a NOS EF732 / 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 AK-47 MkII’s steel headgrille mesh and brass base ring are finished in a reflective chrome plating, giving the microphone a unique look and vibe. The aluminum body tube is finished in a black protective hard coat and is engraved with the microphone model name and serial number. A black and silver TELEFUNKEN diamond logo badge is featured on the front of the microphone. The power supply is also finished in a black protective coating.


Each AK-47 MkII microphone comes complete with M 901 power supply, M 801 25’ dual-shielded TX-7 tube microphone cable, M701 elastic shockmount and wooden microphone box.
