    "The J48 works great. It is very transparent, which is important if you're trying to preserve the sound of your 1962 Fender Precision!"

Radial Pro48 Active Direct Box

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 bookend 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.
