The Radial JDI is considered by many to be the world's finest direct box. It is a passive DI that employs a Jensen isolation transformer for optimum audio performance offering outstanding linearity at all frequencies, combined with extraordinary level handling without introducing distortion. Being completely passive, the plug & play JDI does not require any powering and has the unique advantage of eliminating 60-cycle ground loops. This makes the JDI a definite favorite with informed audio engineers. The JDI is great for guitars, bass, and keyboards and is particularly adept with high-output, broadband instruments such as active instruments and digital keyboards. The JDI may be rack-mounted using the J-Rak and is also available in a stereo (2-channel) version called the JDI Duplex and the 6-channel rack-mountable JD6.


Radial JDI Duplex: A two channel version of the JDI for stereo keyboards, or bass rigs. All the same features as the JDI in a single box. Extremely rugged construction, virtually zero phase distortion, the Duplex is the perfect choice for live stages where eliminating noise is essential.
Radial JD6 Six channel DI: The Radial JD6 is a 6 channel direct box that has been optimized for stage use - Six of the legendary Radial JDI channels are mounted into a single rack space for maximum density. Channels 1 and 2 offer a 'Swiss Army' extended feature set for computer sound cards, keyboards, and studio interface while channels 3 to 6 are optimized for stage.

Radial J-Rack Direct Box rack-mount adaptor: The J-Rack is a unique direct box shelf and 19" rack adaptor that allows up to 8 JDI or J48 direct boxes to be rack-mounted in 2 rack spaces. This unique adaptor allows improved inventory management for sound companies allowing DI inventory to be used as stand-alone or rack mount depending on tour needs.
