ADK FRANKFURT-49 T SPECIFICATIONS

The ADK Custom Shop Frankfurt 49-T Microphone is part of the ADK Custom Shop FET series, which are based on a unique FET circuit that saturates gradually (unlike most condenser microphones which tend to clip abruptly). Key to the Tonality -a Belgian-American-Australian-Designed Capsule, British Oxford Transformers, Hi-End Phillips Norelco Uber-FET. Manufactured with Hi-Fi Methods and Materials, including a $6 Resistor! It took three microphone experts including a PhD in Physics, a Design Genius in Belgium and a 40 year-old Mic Locker to create them! Two-Way Attenuation Pads & Two Way HP Filter to enable end-user to tailor the dynamic behavior of the microphone and create new textures, with rarely the need for outboard processors or even EQ. The Frankfurt 49-T is a tri-polar microphone with selectable Cardioid, Figure-8, and Omni pickup patterns.

All Class-A F.E.T. design manufactured in 3 Zigma Aerospace Manufacturing facility with British Oxford Transformer, and premium quality Low-Noise 3 Zigma capsules with Vintage Voicing Curves. The audiophile circuitry differs from lesser-designs in that it is designed for Soft-Saturation at extremely high SPL as instead of going into the “crunch” and unpleasant distortion (not the good kind of distortion!) of hard-clipping. The Frankfurt 49-T features a very smooth, dark top, but a full mid and bottom end. Great for getting that extremely vintage vibe on would-be harsh sources. Perfect for strings.
