Radial Engineering R8001112 ProAV1 DI Box XLR Cable Bundle

The Radial ProAV1 is a passive single-channel direct box designed for the specific demands of multimedia and AV signal chains — the kind of sources that routinely introduce ground loop hum, impedance mismatches, and noise floor problems into a live or installed sound system. At its core is the Eclipse ET-DB2 custom-wound transformer, which provides galvanic isolation and impedance conversion with a sonic character that stays clean and transparent. Feed it a laptop headphone output, a keyboard line out, an instrument signal, or an RCA feed from a playback device, and you get a balanced, low-impedance XLR output ready for long cable runs to front-of-house without picking up interference along the way. The transient handling is notably robust — the transformer absorbs hot peaks from DJ mixers and digital playback without the saturated compression you'll hear from lesser passive DI boxes.

Build quality follows Radial's established standard: a steel chassis that survives road use, clearly labeled I/O, and a ground lift switch for addressing hum without fumbling. The four input options — 1/4-inch, RCA, 3.5mm, and female XLR — make this genuinely versatile for corporate AV, houses of worship, and live venues where the source device changes from gig to gig. Being passive means zero self-noise and no power dependency, but it also means no gain is available, so very weak sources may need help upstream. This XLR cable bundle makes the ProAV1 a grab-and-go solution for anyone who needs a reliable, transparent conversion stage between consumer-level sources and professional audio systems.
