{"product_id":"radial-jdi-duplex-di-passive-157261","title":"Jdi Duplex DI Passive","description":"\u003ch3\u003eA Logical Evolution of the JDI, Designed for Modern Setups\u003c\/h3\u003e\u003cp\u003eWhile the Radial JDI has established itself as a studio and stage reference, the \u003cstrong\u003eJDI Duplex\u003c\/strong\u003e carries its DNA forward while addressing two very concrete needs: \u003cstrong\u003emore connections\u003c\/strong\u003e and true \u003cstrong\u003estereo management\u003c\/strong\u003e (or dual mono). Designed to offer maximum flexibility to sound engineers, it is based on a high-end passive architecture, with two independent channels and an expanded interface to accommodate a wide variety of sources, from instruments to multimedia equipment.\u003c\/p\u003e\u003cp\u003eWithin the Radial range, the JDI Duplex positions itself as an \"all-in-one\" solution to secure the audio chain: impedance matching, galvanic isolation via transformers, and practical signal control without requiring external power. The goal is clear: to obtain a usable, stable, and musical signal regardless of stage or patch constraints.\u003c\/p\u003e\u003ch3\u003eFor Whom and What: From Studio to Stage, and From Instrument to Audio Player\u003c\/h3\u003e\u003cp\u003eThe JDI Duplex is aimed at those who need to connect sometimes finicky, often powerful, and always different sources: \u003cstrong\u003ekeyboards\u003c\/strong\u003e, \u003cstrong\u003esamplers\u003c\/strong\u003e, \u003cstrong\u003eelectronic drums\u003c\/strong\u003e, \u003cstrong\u003esound modules\u003c\/strong\u003e, \u003cstrong\u003eactive basses\u003c\/strong\u003e, \u003cstrong\u003eacoustic guitars with preamps\u003c\/strong\u003e, as well as audio outputs from computers, interfaces, or players. It is also very relevant for \"taming\" digital sources considered too direct, providing a more organic response and better integration into a mix.\u003c\/p\u003e\u003cp\u003eThanks to its two channels, it can serve as a \u003cstrong\u003estereo DI\u003c\/strong\u003e (keyboard, module, playback) or a \u003cstrong\u003edual DI\u003c\/strong\u003e (two instruments, two submixes, two lines). And when the context requires mono operation, the summing function simplifies routing without sacrificing the coherence of your setup.\u003c\/p\u003e\u003ch3\u003eA Passive DI Designed for High-Level Signals\u003c\/h3\u003e\u003ch4\u003eJensen Transformers: Warmth, Precision, and Isolation\u003c\/h4\u003e\u003cp\u003eThe heart of the JDI Duplex relies on a pair of \u003cstrong\u003eJensen transformers\u003c\/strong\u003e, renowned for their ability to transfer the signal with great stability and musical fidelity. The result aims to preserve the character of the instrument while reducing common stage issues: induced noise, interference, ground potential differences between devices, or hum caused by ground loops. This \"quality-first\" approach makes the JDI Duplex a direct box suited for demanding situations where a clean signal is expected right at the console input.\u003c\/p\u003e\u003ch4\u003eExtended Connectivity: Plug In, Adapt, Secure\u003c\/h4\u003e\u003cp\u003eEach channel features parallel \u003cstrong\u003e6.35mm Jack\u003c\/strong\u003e and \u003cstrong\u003eRCA\u003c\/strong\u003e inputs, plus a dedicated \u003cstrong\u003eXLR\u003c\/strong\u003e input for line-level sources. The idea is to quickly integrate an instrument source, a player output, or professional equipment without multiplying boxes and adapters. The \u003cstrong\u003eXLR\u003c\/strong\u003e outputs send the signal to the console, while the \u003cstrong\u003ethru\u003c\/strong\u003e output maintains a path to an amplifier or a high-impedance device.\u003c\/p\u003e\u003ch4\u003eSignal Control: The Right Switches in the Right Place\u003c\/h4\u003e\u003cp\u003eOn the front panel, Radial includes essential functions to save time and avoid surprises. The \u003cstrong\u003e-15 dB PAD\u003c\/strong\u003e helps handle very strong signals, the \u003cstrong\u003eground lift switch\u003c\/strong\u003e quickly addresses hum issues, the \u003cstrong\u003epolarity inverter\u003c\/strong\u003e facilitates coherence in multi-source setups, and the \u003cstrong\u003einput selector\u003c\/strong\u003e optimizes the choice of the active source. Finally, the \u003cstrong\u003eMerge\u003c\/strong\u003e (summing) function allows grouping inputs to feed a mono output when the stage plan or console input requires it.\u003c\/p\u003e\u003ch4\u003eRadial Durability: Ready for the Road\u003c\/h4\u003e\u003cp\u003eThe JDI Duplex is designed to be handled, transported, and used in tough environments. Its robust chassis protects connectors and switches, while the design aims to minimize mechanical stress on the electronics. On stage or in performance, this is the type of DI you deploy without hesitation: reliable, stable, and built to last.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical
