ProDI™ Specifications

The Radial ProDI is a professional grade passive direct box that employs the same high quality audio transformer used in the ProD2, ProAV1, ProAV2 and ProD8. Designed to be 'plug and play' easy to use, the ProDI supports a standard feature set that is ideally suited for live touring, yet equally effective for the studio. It is able to withstand exceptional signal levels while delivering a clean, natural tone with minimal distortion of all types.
