The design begins with a rugged extruded aluminum shell with a slide-in U body that comes standard with gold plated XLR connectors. Inside, a premium Jensen mic input transformer is equipped with dual Faraday internal shields and external mu-metal cans to reduce susceptibility to RF and electro-magnetic induction. Isolating the microphone further reduces common mode noise by as much as 130 dB, optimizing signal to noise. Sonically, the MI-XX delivers a ruler flat response from 5 Hz to 100 kHz with less than 2° phase shift at 20Hz. And as with all Jensen audio isolators, the MI-XX produces the warm Bessel curve that Jensen is renowned for, yielding a tonal character reminiscent of the very finest vintage studio equipment.

Plug and play easy to use, this passive interface does not require any power to work. This makes the MI-XX an ideal sonic enhancer for both dynamic and condenser microphones in the most demanding recording studio environments.
