The Radial JDI Stereo is considered by many to be the world’s finest stereo direct box. It is a passive DI that employs a pair of Jensen isolation transformers 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 Stereo does not require any powering and has the unique advantage of eliminating 60-cycle ground loops. This makes the JDI-Stereo a definite favorite with informed audio engineers. The JDI-Stereo 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.

You expect only the best from your stage equipment, and your direct box is no different. Go with the industry standard JDI Stereo today and keep on making music for years to come.
