Radial Engineering Pro48:Pro48 innovative internal switching power supply significantly increases headroom producing less distortion while yielding a smooth, linear response that extends from 20Hz to well above 40kHz. This results in natural, uncolored signal that is as good or better than DI boxes costing several times more. The superior performance makes the Pro48 an ideal candidate for use with battery powered active basses and acoustic guitars that tend to overload other direct boxes.
The Pro48 is constructed using 14 gauge steel with Radial’s 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.
