Radial JDX 48

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.
