This box can handle very high signal levels \nwithout distorting, and its passive design helps to eliminate 60-cycle ground loops. Great for everything from passive and active guitars and basses to analog \nand digital keyboards, the Radial JDI is a dependable, quality performer!\n\u003c\/p\u003e\n\n\u003ch4\u003eRadial JDI at a Glance\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eJensen transformer-equipped passive DI\u003c\/li\u003e\n  \u003cli\u003e100% isolation eliminates ground loops\u003c\/li\u003e\n  \u003cli\u003eVirtually zero phase \u0026amp; harmonic distortion\u003c\/li\u003e\n  \u003cli\u003eExceptional signal handling\u003c\/li\u003e\n  \u003cli\u003eHigh common mode noise rejection\u003c\/li\u003e\n  \u003cli\u003eWelded I-beam construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eJensen Transformer for Optimum Performance\u003c\/h4\u003e\n\u003cp\u003e\nThe JDI's Jensen transformer is the product of decades of experience in transformer production. This transformer delivers optimum audio performance offering \noutstanding linearity at all frequencies, combined with extraordinary level handling without introducing distortion.\n\u003c\/p\u003e\n\u003cp\u003e\nThe 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, \nenabling stereo-to-mono summing. This is especially useful for interfacing stereo sources such as keyboards or CD players in live shows where audio channels \nare not always plentiful. The JDI also includes a -15dB pad for interfacing with higher output levels.\n\u003c\/p\u003e\n\u003cp\u003e\nThe output panel features a balanced 600-ohm XLR connector with pin-2 hot, following AES specifications. A polarity reverse switch toggles pin-2 and pin-3 to \nallow compatibility with older non-AES equipment and creative phase manipulation. The ground lift switch disconnects the XLR pin-1 ground from the JDI for \n100% input-to-output isolation.\n\u003c\/p\u003e\n\u003cp\u003e\nA second -30dB pad can be engaged and, when used with the -15dB input pad, allows the JDI to be connected in parallel with a speaker. This enables engineers \nto “tap” the sound from a guitar amplifier speaker post-distortion, adding another creative dimension. This mode incorporates a speaker emulation filter \nthat rolls off highs and lows to approximate the sound of a 12\" driver.\n\u003c\/p\u003e\n\n\u003ch4\u003eConstruction\u003c\/h4\u003e\n\u003cp\u003e\nAs with all Radial direct boxes, the JDI is designed for use in abusive environments such as fast-paced concert stages. An innovative book-end design protects \nswitches and connectors by creating a guarded zone that makes them nearly impossible to damage.\n\u003c\/p\u003e\n\u003cp\u003e\nThe inner skeletal frame features a rugged 14-gauge welded I-beam construction that prevents torque from being applied to the PCB — the most common cause of \ndirect box failure due to stress-induced intermittent solder joints.\n\u003c\/p\u003e\n\u003cp\u003e\nA full-bottom no-slip rubberized pad keeps the JDI firmly in place when resting on an amplifier and adds electrical shock resistance by shielding the unit \nfrom metal amp handles that are often directly coupled to the amp chassis.\n\u003c\/p\u003e\n\u003ch4\u003eWhat Radial Says...\u003c\/h4\u003e\n\u003cp\u003e\nThe JDI is a high-performance passive direct box built for live concert touring and professional studio recording. \nEquipped with a premium Jensen transformer, it delivers exceptional audio performance with unrivaled clarity, reliability, \nand sonic integrity.\n\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eJensen Transformer equipped passive DI\u003c\/li\u003e\n  \u003cli\u003eEliminates hum and buzz from ground loops\u003c\/li\u003e\n  \u003cli\u003eVirtually zero phase \u0026amp; harmonic distortion\u003c\/li\u003e\n  \u003cli\u003eExceptional signal handling and noise rejection\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003ePure Sound of the Instrument\u003c\/h4\u003e\n\u003cp\u003e\nThe Radial JDI is engineered to handle extremely high signal levels without introducing any form of distortion. \nAt its core is the world-class Jensen JT-DB-EPC audio transformer, delivering a smooth, warm Bessel curve reminiscent of \nthe finest vintage equipment. With a ruler-flat response from 10Hz to 40kHz and virtually zero phase deviation, the JDI \nreproduces the natural, pure sound of your instrument without coloration or artifacts.\n\u003c\/p\u003e\n\u003cp\u003e\nThanks to its passive, no-power design, the JDI performs both high-to-low impedance conversion and signal balancing over \na magnetic bridge that transfers audio while rejecting stray DC voltage. This makes it extraordinarily effective at \neliminating hum and buzz caused by problematic ground loops, ensuring clean, professional-grade performance in any environment.\n\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n[tabs] [tab title=\"FEATURES\"]\n\u003ch4\u003eRadial JDI Features:\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWelded I-beam construction prevents torque on the PC board, virtually eliminating cold solder joints — the No.1 cause of field failure.\u003c\/li\u003e\n  \u003cli\u003eInnovative “slide-in-place” XLR trace allows the use of I-Beam girder construction.\u003c\/li\u003e\n  \u003cli\u003eJensen transformer provides distortion-free performance.\u003c\/li\u003e\n  \u003cli\u003eMilitary-grade PC board ensures maximum durability;
