Pro48™ Active Direct Box
Part No. R800 1105
High performance active direct box
Increased dynamic range and headroom
48V phantom powered with switching supply
Ideal for acoustic guitar and bass
The Radial Pro48 is a compact high-performance 48V phantom powered active direct box designed specifically for todays high output 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.
The compact Pro48 is built road-ready with 14 gauge steel throughout. A unique book-end™ design creates a protective zones around the switches and connectors while the internal I-beam construction assures outside stress will not torque the PC board and deteriorate solder connections. A full bottom no-slip pads adds mechanical isolation and electrical insulation to further extend the Pro48's lifespan.
Exceptional sonic performance, great natural tone and an affordable price tag! The Radial Pro48 truly represents a breakthrough in value.
The Radial Pro48 is a high performance direct box that employs the same circuit design and switching power supply that has made the Radial J48 a standard on professional tours around the globe. The Pro48's smaller footprint force tighter part placement which in turn makes the circuit design more challenging. Yet the resulting tests prove that the Pro48 is able to stand up to other direct boxes costing significantly more. Low distortion and super quiet, the Pro48 is easily the best 48V phantom powered active direct box in its price category made today.
