The Pro48 from Radial Engineering is a high-performance, active direct box designed specifically for guitars and bass with active pickups that produce considerably higher output. It exhibits excellent headroom and dynamics.
Utilizing 48V phantom power from a mixing console, the unit employs an innovative digital switching power supply that significantly increases headroom and allows for less distortion while yielding a smooth, linear response.
This makes the Pro48 an ideal candidate for use with battery-powered active basses and acoustic guitars that tend to overload direct boxes. An input pad helps prevent overload from hot signals and a ground-lift switch is provided to reduce noise caused by ground loops.
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.
