DESCRIPTION
The Pro48 is an active direct box designed for use on stage or in home recording studios, with exceptional signal handling for use with both active and passive instruments.
The Pro48’s 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.
