The Radial Pro48 is a high-performance 48V phantom powered active direct box designed specifically for today's higher output instruments. The Pro48's inovative 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 our unique book-end 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. Exceptional sonic performance, great natural tone at an affordable price; the Radial Pro48 truly represents a breakthrough in value! The Radial Pro48 Blue is True!
