Radial ProDI: The Dependable Passive Direct Box for Stage and Studio

The Radial ProDI is your go-to passive direct box, designed to deliver exceptional audio performance in a rugged, reliable package. Whether you're on stage or in the studio, this compact direct box combines solid construction with top-tier audio quality, making it the ideal choice for a wide range of applications.

Exceptional Audio Quality

At the heart of the ProDI lies a custom-wound Radial transformer. This high-quality transformer boasts an impressive 140kOhm input impedance, reducing loading on your instruments while ensuring that the ProDI can handle extreme signal levels across all frequencies without distortion. To further enhance performance, an internal mu-metal shield provides protection against electromagnetic fields that could otherwise cause unshielded transformers to distort.

Rugged Construction

Built to withstand the rigors of professional use, the ProDI features a robust 14-gauge steel I-beam skeleton for added rigidity. Radial's unique book-end design creates a protective zone around the switches and connectors, ensuring they can handle the demands of stage and studio environments. The use of glass-filled nylon connectors and high-cycle switches, combined with a mil-spec PCB and internal RF filtering, guarantees durability and noise-free operation.

Versatile Applications

The ProDI is a versatile workhorse, suitable for a wide range of instruments, including bass guitars, active acoustics, keyboards, and more. Its compact size, exceptional performance, and affordability have made it one of the most popular direct boxes on the market. Whether you're a touring musician or a studio engineer, the Radial ProDI offers spectacular performance at a price that fits any budget.
