BSS AR133 ActiveDI Box

The BSS AR133 is a professional active DI box designed to deliver clean, dependable signal conversion on stage and in the studio. Built by BSS Audio, it turns high‑impedance, unbalanced sources into balanced, mic‑level signals that travel long cable runs with minimal noise and interference. Whether you are connecting guitars, basses, keyboards, acoustic instruments with pickups, drum machines, or playback devices, the AR133 preserves clarity and punch while simplifying gain staging for front‑of‑house and recording workflows. Power flexibility is at the heart of the AR133. It operates from standard 48V phantom power supplied by most mixing consoles, or from a 9V battery when phantom is not available, ensuring reliable performance in touring, rental, and installed environments. The unit provides a balanced XLR output to your console, plus a 1/4" input and a link/thru jack to feed an onstage amplifier simultaneously. A ground lift switch helps eliminate hum caused by ground loops, while a three‑position pad (0 dB, ‑20 dB, ‑40 dB) lets you match instrument, line, and even speaker‑level signals safely and effectively. Durability is a hallmark of the AR133. Its rugged, road‑ready metal chassis with protective end pieces shields the circuitry and keeps connectors and switches protected from accidental knocks. This makes it a dependable choice for demanding live productions, houses of worship, theaters, broadcast, and project or commercial studios. With rock‑solid build quality, low‑noise performance, and practical control features, the BSS AR133 has become a go‑to direct box for engineers and musicians who need consistent results night after night.
