Radial JDI MK3 Passive Direct Box

Considered by many to be one of the finest passive-operation direct boxes available, this DI employs a Jensen isolation transformer for optimum audio performance. 60-cycle ground loop elimination and adept handling of high-output, active instruments and keyboards make it discrete and versatile. Steel I-beam construction, baked enamel finish, and protected faceplate mean it"s built to survive.The Radial JDI passive direct box employs the Jensen JT-DBE transformer as its main drive engine. The Jensen DBE transformer employs a laminated nickel core with low-permeability and no magnetic memory, therefore eliminating phase distortion caused by the disruption of fundamentals and harmonics.The distinctive book-end design protects the switches against damage from abuse by providing a protective zone on both I/O panels. A baked enamel finish resists scratching while a no-slip rubberized pad on the bottom stops the JDI from moving around and aids isolation. Inside, the JDI features compound, welded I beam construction that protects the sensitive electronics from outside stress. The internal skeletal frame is locked together with 4 hex screws.The input panel features a 1/4' instrument input and traditional thru-put. An innovative merge function allows the thru-put to be converted to a second input to allow stereo to mono summing. This is useful for interface with stereo sources such as keyboards or CD players in live shows where audio channels may be not always be plentiful. T
