Incorporating a solid, reliable body with extraordinary audio quality, the ProDI™ is a passive direct box that is ideal for both studio and stage alike. With an internal MuMETAL® shield, the isolation removes any distortion or noise created by ground loops leaving you with a clean signal.

World Class DI

The heart of the ProDI is a custom wound Radial transformer. It features an exceptionally high 140kΩ input impedance to reduce loading while enabling the ProDI to handle extreme signal levels at all frequencies without distortion. This is further improved upon with an internal MuMETAL® shield to protect against electromagnetic fields that can cause unshielded transformers to distort.
