Radial Engineering ProD2 Stereo Passive Direct Box – Professional Dual Channel DI Box for Keyboards, Synthesizers & PA Systems

Product Introduction

The Radial Engineering ProD2 is a premium 2-channel passive direct box specifically designed to connect stereo keyboards, digital pianos, synthesizers, drum machines, samplers, and other high-output instruments to professional PA systems, audio interfaces, and recording consoles. Equipped with high-performance Eclipse ET-DB2 transformers, the ProD2 delivers exceptional audio clarity, natural warmth, and superior noise rejection without requiring external power.

Ideal for live sound, worship facilities, touring systems, recording studios, schools, and professional AV installations, the ProD2 ensures pristine audio transmission while eliminating hum, buzz, and distortion commonly associated with ground loops and long cable runs.

Product Description

The Radial ProD2 is engineered to provide superior stereo signal conversion for professional audio applications. At the heart of the design are two custom Eclipse ET-DB2 audio transformers that offer an exceptionally flat frequency response from 20Hz to 20kHz while handling extremely high signal levels without distortion.

Unlike active direct boxes that can clip when signal levels exceed their operating voltage, the ProD2’s transformer-based design naturally saturates in a musical way, gently smoothing aggressive transients and reducing harsh digital artifacts. This characteristic makes it particularly effective when used with digital pianos, synthesizers, samplers, and drum machines that often generate wide dynamic ranges.

The transformer-isolated design also eliminates hum and buzz caused by ground loops, ensuring clean and balanced audio signals for professional sound reinforcement and recording applications. Whether on stage, in the studio, or integrated into a touring rack system, the ProD2 provides reliable performance and exceptional sonic quality.
