Description
When active basses and acoustic-electric guitars push more output than a standard DI can handle, the Radial Pro48 keeps the signal clean rather than clipped. This 48V phantom-powered active direct box uses a digital switching power supply to extend headroom well beyond typical designs, so hot pickups and preamp-loaded instruments pass through without distortion or level compromise.
Frequency response runs a flat 20Hz to over 100kHz, meaning the Pro48 doesn’t impose its own character on the source — what goes in comes out sounding like the instrument, not the box. That kind of transparency matters on stage when a bassist’s tone needs to translate identically from monitor wedge to front-of-house mix, and it matters in the studio when a DI’d acoustic needs to sit accurately in a track.
Radial builds the Pro48 from 14-gauge steel in their book-end chassis style, which shields the switches and connectors within protective end zones — a practical detail for touring gear that gets loaded in and out night after night. Inside, welded I-beam construction keeps outside stress from reaching the PC board, so cable yanks and rack bumps don’t translate into intermittent connections or premature failure down the line.
For techs speccing DI boxes for a rider or rounding out a rack of stage boxes, the Pro48 offers high-resolution active performance in a footprint small enough to disappear at a monitor position.
