Telefunken AK-47 MKII



The AK-47 MKII Tube Microphone from Telefunken is a part of their acclaimed R-F-T series. The microphone features a large diaphragm condenser element and a custom output transformer that borrows from the historic BV8 transformer found in the vintage U-47 and U-48 microphones. The AK-47 MKII’s tube stage features an NOS Telefunken EF-732 vacuum tube, delivering pristine audio fidelity, low noise and vintage analog warmth. The AK-47 MKII features omnidirectional, cardioid, and figure 8 polar patterns with 6 intermediate stages for each pattern.
