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.
High-resolution active direct box
48V phantom powered with digital switching
Excellent headroom and dynamic range with low noise floor
Ground-lift switch, when activated helps to reduce hum and buzz caused by ground loops
Pad switch engages a -15 dB pad to reduce the input level and prevent overload from high-output devices like CD players and active pickups
Connectors are 100% electrically isolated from the chassis
Inner steel enclosure is made extremely rigid with an I-beam profile, eliminating any stress that could torque the PC board and cause solder joint failure
Military-grade, double-sided PCB is bolted to steel standoffs for road-toughconstruction
For live situations the neoprene foam foot provides electrical isolationand plenty of friction to stay put
