Radial Engineering has announced it has started shipping the JDX 48 Amplifier direct box.

The JDX 48 is the successor to the JDX Reactor amplifier DI, and the new model's design begins with the same circuitry and transformer-coupled reactive load found on the original. This captures both the sound from the amp head along with the back electromagnetic impulse from the loudspeaker, promising a more realistic rendering than the usual resistive pad offered by other manufacturers.

This signal is then processed via a multi-stage filter to emulate the tone of a 4x12 half-stack cabinet when used with a guitar, or a 8x10 cabinet when used with a bass. The JDX 48 also includes a Bass Extension switch for increased bottom end when desired, and a 100W/300W switch to change the input capability.

Radial product specialist Jay Porter commented: "The JDX has become a staple in professional touring, clubs and houses of worship worldwide. While many engineers were initially skeptical because of previous bad experiences with different 'red boxes', the JDX has rapidly gained popularity thanks to its natural, consistent tone. It has also become a go-to piece for use with in-ear monitor systems, delivering a guitar tone that players love."

The unit also has the ability to use 48 volt phantom power.

"As soon as we released the JDX, folks started asking us if there was any way to power the box using standard 48V phantom,” Porter continued. “The included 15V power supply was fine for most applications, but space and power outlets are always at a premium on stage. Plus carrying multiple power supplies for different areas of the world is painful for our touring clients. We started looking at ways to reduce the current draw of the JDX so it would run on phantom power without sacrificing the exceptional tone, and it wasn't easy! After several rounds of prototyping, we were finally able to reduce the current requirements of the Class-A circuitry with all of the tone intact."

"Another request was to increase the power handling of the JDX. While the original was designed for guitar amps with a 100 Watt output, many folks loved using it with higher-powered amps such as the Ampeg SVT. While this was always possible at lower volumes, extra care needed to be taken to ensure that amplitude peaks did not exceed 100 Watts," he concluded.

MAP price for the JDX 48 is $199.99 USD.
