The Radial ProD2 is a high-quality passive stereo direct box built for professional performance, durability, and ease of use. Designed for active acoustic guitars, basses, electric pianos, synthesizers, drum machines, samplers, DJ mixers, and playback devices, the ProD2 delivers clean, noise-free signal conversion in any environment. Featuring custom isolation transformers, rugged construction, and true plug-and-play simplicity, it’s a trusted solution for both stage and studio.
The Radial ProD2 and its mono counterpart, the ProDI, are full-range passive direct boxes. Active DI boxes use powered electronic circuits to convert impedance and balance signals, requiring batteries, phantom power, or external supplies. Passive DI boxes rely entirely on high-quality transformers, needing no power while providing superior noise reduction. With its custom Radial transformers, the ProD2 excels at eliminating system noise and ground hum without requiring any external power source.
Equipped with custom-built audio transformers, the ProD2 provides exceptional signal handling without saturation and virtually no phase distortion in critical frequency ranges. These transformers deliver 100% isolation to eliminate ground loops while preserving full signal integrity. Internally, isolated XLR connectors prevent chassis ground issues, while a military-spec PC board with a full surface ground plane minimizes RF interference—resulting in outstanding sonic clarity at an accessible price.
The ProD2 offers true plug-and-play simplicity. Connect your instrument to the 1/4" inputs, send the signal to onstage amps via the thru jacks, and feed the mixer through the XLR outputs—simple and fast. Engage the -15dB pad for hot signals or use the ground lift to eliminate unwanted noise. Whether you're using acoustic guitars, basses, or electronic keyboards, the ProD2 naturally preserves tone while delivering clean, consistent, and noise-free output.
Inside the ProD2, every component reflects Radial’s reputation for unmatched durability. Its book-cover design protects switches and connectors, while the 14-gauge welded I-beam chassis prevents torque stress on the internal circuitry—eliminating one of the most common causes of DI failure. A full-bottom no-slip rubber pad enhances mechanical stability, provides electrical insulation, and ensures the DI stays firmly in place during demanding professional use. Built for life on the road, the ProD2 delivers reliability you can count on.
The ProD2 is a 2-channel passive direct box engineered to connect stereo keyboards and high-output instruments to any PA system or recording setup with complete clarity. Designed to eliminate noise and distortion, it delivers smooth, consistent sound quality whether used on stage or in the studio. With robust handling of transients and optional rack-mounting capability, the ProD2 is a reliable tool for touring rigs and professional audio workflows.
At the core of the ProD2 are two Eclipse ET-DB2 transformers that deliver exceptional performance from 20Hz to 20kHz with minimal deviation above 18kHz. These high-grade transformers withstand enormous signal levels without distortion, naturally smoothing peaks through transformer saturation. This subtle rounding effect is ideal for digital keyboards, samplers, and drum machines that often produce sharp transients. The transformer-based design also provides outstanding hum and buzz elimination, ensuring clean audio even in challenging environments.
The ProD2 is purpose-built for stereo instruments such as keyboards. Its straightforward signal path makes connecting your keys to a recording interface or PA system incredibly easy, delivering full, rich stereo sound every time.
Effectively acting as two Radial ProDI boxes in one unit, the ProD2 is a versatile choice for multi-instrumentalists. From bass guitars to acoustic-electric instruments and various pickup-equipped sources, it provides clean, distortion-free signal conversion across a wide range of applications.
Whether you're running electronic drums, samplers, or DJ mixers into a PA, the ProD2 handles hot signals effortlessly. Its generous headroom and transformer isolation ensure consistent, noise-free output, making it a dependable solution for modern electronic performance setups.
