Radial ProDI 1-Channel Passive Instrument Direct Box

Professional musicians and audio engineers know that signal integrity can make or break a performance, which is why the ProDI™ stands as the go-to passive direct box for both stage and studio applications. Built around a custom wound Radial transformer with an exceptionally high 140kΩ input impedance, this unit excels at handling extreme signal levels across all frequencies without introducing distortion.

The ProDI™ combines outstanding audio performance with robust construction that you can rely on night after night. Its transformer isolation effectively eliminates troublesome ground loops that plague many audio setups, while the compact design makes it perfect for cramped stage environments and studio racks alike.

Key features include a standard 1/4" instrument input connection and a -15dB pad that reduces input sensitivity when working with hot signals. The plug-and-play design means you can focus on your performance rather than wrestling with complicated setup procedures, making it an essential tool for any serious audio professional.
