The Radial ProD2 is a passive stereo direct box built for keyboards, drum machines, DJ systems, amp/cab sims, and other line‑level stereo instruments, using two custom Eclipse transformers that provide smooth, warm tone while handling high signal levels without distortion; their transformer isolation also eliminates hum and buzz from ground loops, preserving clean audio even with problematic sources. Each channel includes a 1/4‑inch input with a thru output for feeding a stage amp, along with a ‑15 dB pad for hot signals and a ground‑lift switch for noise troubleshooting, all housed in Radial’s rugged 14‑gauge steel “bookend” chassis designed to survive touring and rental use. With a linear response roughly from 20 Hz to 18.5 kHz and the ability to handle +18 dB inputs without saturation, the ProD2 provides reliable, fuss‑free conversion from high‑impedance instrument outputs to balanced XLR feeds for consoles and stage boxes, making it a dependable workhorse for live and studio environments.
