The Radial ProD2 Passive Direct Box is a rugged, great-sounding stereo DI designed to handle everything from keyboards and samplers to laptops, drum machines, and playback rigs with total reliability. The Radial ProD2's warm sound, legendary build quality and compact design have made it the most popular stereo direct box made today. Built around Radial’s custom-wound transformers, the ProD2 delivers clean, natural sound while eliminating noise, ground loops, and signal loss—making it a trusted go-to for studios, stages, and broadcast environments. The ProD2 features a completely passive design that requires no power, making it incredibly dependable in live and mobile setups. Each channel is transformer-isolated to provide excellent noise rejection and wide frequency response, while handling hot line-level signals without distortion. A -15 dB pad on each channel allows it to easily accommodate high-output sources, and the ground lift switches help eliminate hum and buzz in problematic systems. Housed in Radial’s signature steel book-end enclosure, the ProD2 is built to survive years of touring and daily studio use. Whether you’re running stereo keyboards, DJ mixers, playback tracks, or line-level audio into a console, the ProD2 delivers consistent, professional results every time.
