The Radial ProAV2 is a passive stereo direct box designed as a flexible, problem‑solving interface for events, presentations, and live sound, especially when dealing with a mix of professional and consumer audio sources. It accepts inputs from 1/4‑inch jacks, RCA, and 3.5 mm devices (everything from laptops and phones to keyboards and playback decks) and converts them to clean, balanced XLR outputs. Its transformer‑based design handles high signal levels without distortion and naturally smooths harsh digital sources, while providing isolation to eliminate hum, buzz, and other ground‑loop noise. The ProAV2 requires no power, works quietly in any setup, and is built in a rugged 14‑gauge steel chassis that can withstand daily use in corporate AV, touring, and rental environments.
