Radial’s JDX 48 Amplifier Direct Box is Now Shipping

Radial Engineering Ltd. in Vancouver, British Columbia, announces that its JDX 48 Amplifier direct box ($199.99) is now shipping. The JDX 48 is the next generation version of the JDX Reactor amplifier DI.

The JDX 48’s design begins with the same 100-percent discrete Class-A circuitry and transformer-coupled reactive load found on the original unit. This captures both the sound from the amp head along with the back electromagnetic impulse from the loudspeaker, and is designed to produce a more realistic rendering than a resistive pad.

This signal is then processed via a carefully designed multi-stage filter to emulate the tone of a 4×12 half-stack cabinet when used with guitar, or an 8×10 cabinet when used with bass.

The JDX 48 now also includes a Bass Extension switch for increased bottom end when desired, and a 100/300-watt switch to change the input capability.

The new JDX also includes the ability to use 48-volt phantom and higher power amplifiers, and add a low frequency extension to the voicing.
