The Radial Engineering J48 Active Direct Box, a pioneering solution for capturing pristine instrument signals. Designed for 48V phantom power, the J48 employs a unique switching power supply to produce 9V peak transients without distortion. The result is a DI with extremely low noise, half the intermodulation distortion and significantly improved dynamics compared to other units.

Ultra-Clean Signal With Maximum Headroom

The J48 has been optimized to work within the current limits of standard phantom power while still delivering maximum headroom. Its custom circuitry achieves exceptionally low distortion and a frequency response wider than most other DIs for transferring the full detail of your instrument's tone.

Reduce Noise and Hum

In addition to its low inherent noise, the J48 provides a ground lift switch to eliminate hum from ground loops. It also features an 80Hz high-pass filter to remove unwanted low-end rumble. For extra gain before feedback, engauge the -15dB pad.

Enhance Functionality

The J48 includes additional features to enhance its capabilities. A polarity reverse switch corrects for reversed pin 2 and 3 wiring. The merge function mixes two inputs to mono for combining signals from active and passive pickups.

Road-Ready and Built to Last

Like all Radial products, the J48 is constructed for the demands of live touring. Its 14-gauge steel I-beam frame and welded construction provide exceptional durability. The J48 delivers audiophile sound quality and rugged reliability—perfect for both studio and stage. Experience the difference a great DI can make to your tone.
