The JDX 48™ is a direct box designed to capture the sound of an electric guitar amplifier by connecting between the amp head and the speaker cabinet, providing a balanced feed for the PA system that sounds like a well-placed microphone on your amp.

• Capture the sound of your amplifier through a direct box
• Delivers consistent tone across every performance
• Works equally well on electric guitar and bass
• Can be powered from 48V phantom or DC supply

Deliver your amp's tone through the PA

The JDX 48 makes it easy to get a consistent and natural amplifier tone through the PA system night after night, by taking a feed directly from your amplifier and employing Radial's popular JDX speaker emulation that produces an effect similar to placing a dynamic microphone in front of a 4x12 half stack cabinet. This gives you a more manageable sound onstage for gigs where feedback is an issue, or if mic'ing your amp isn't an option. For artists that employ in-ear monitoring systems, the JDX 48 provides consistent tone each night in the monitor mix for shorter setup times and a more comfortable audio feed for the artist.

Dual powering options

The JDX 48 can be powered using 48V phantom from the mixing console, for a cleaner setup on stage that eliminates the need to carry a power supply to the gig. However, for times when phantom power may not be available, the JDX 48 also ships with a separate DC power supply - giving you a redundant powering option so you never have to perform without your JDX.

JDX 48 Applications

Using the Radial JDX 48 on guitar

The Radial JDX is connected in between the head and the cabinet where it taps a minute signal off the circuit. The reactive load captures both the sound from the head and the impulse from the cabinet for a more realistic tone.

Using the Radial JDX 48 on bass

Bass guitar sounds amazing with the JDX! You get a fat low-mid punch and extra clarity that makes the bass stand out. It truly sounds like you are playing through an SVT with all the grind and drive… yet it is coming through the PA.

Using the JDX 48 with a mic and the Phazer

For even more fun, combine the direct sound of the JDX with a microphone. Use the Radial Phazer to time-align the two signals and be prepared for the biggest, fattest, most amazing tones ever. Careful… this is addictive!

"Fans don't care about the technology... so long as the bass and guitars make Godzilla weep and hide like a beaten puppy. The Radial JDX works."

"My Radial boxes are in constant use, I take them everywhere. The DIs are crystal clear, I love the JDX for recording amps, the SGI and X-Amp are so useful that I don't know how I managed without them before. On top of that, they're built like tanks!"

"The Radial JDX eliminates bleed and potential feedback while producing a familiar sound. The day to day consistency lets me bring the faders up with confidence."
