Product Description
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.

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