Radial ProDI Passive Direct Box

The Radial ProDI is a passive direct box that combines exceptional audio performance with solid dependable construction, making it the ideal general duty direct box for stage and studio.The heart of the ProDI is a custom wound Radial transformer. It features an exceptionally high 140k_ 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 mu-metal shield to protect against electromagnetic fields that can cause unshielded transformers to distort.This compact direct box begins with 14-gauge steel I-beam skeleton for added rigidity and Radial's unique book-end design that creates a protective zone around switches and connectors. Glass filled nylon connectors and high cycle switches combine with the mil-spec PCB and internal RF filtering to provide durability and noise-free performance. A full bottom no-slip pad provides both mechanical isolation and electrical insulat
