Radial Engineering Pro48 Active 48-Volt Compact Active Direct Box

The Radial Pro48’s innovative digital switching power supply significantly increases headroom and allows for less distortion while yielding a smooth, linear response extending from 20Hz to well above 100kHz resulting in natural, uncolored signal transfer. This superior performance makes the Pro48 an ideal candidate for use with today’s battery-powered active basses and acoustic guitars that tend to overload other direct boxes.

The compact Pro48 is built road-ready with 14-gauge steel in a unique bookend design that provides protective zones around the switches and connectors. The internal welded I-beam construction assures outside stress will not torque the PC board thus assuring longer product life.

Pro48 – typical applications

The Pro48 is designed for high-use applications wherever an active direct box is called for. A 15dB pad switch is provided to tame hot signal and expands the range of instrument preamps and the ground lift switch helps eliminate hum and buzz problems caused by ground loops.
