THIS PRODUCT IS FOR ONLINE ORDER ONLY. World's Finest DIThe JDI is a high performance passive direct box for live concert touring and professional studio recording applications featuring a premium Jensen transformer for exceptional audio performance.PhotosJensen Transformer equipped passive DIEliminates hum and buzz from ground loopsVirtually zero phase & harmonic distortionExceptional signal handling and noise rejectionPure Sound of the InstrumentThe Radial JDI is a passive direct box designed to handle extreme signal levels without distortion of any kind. At the heart the Radial JDI employs the world class Jensen JT-DB-EPC audio transformer delivering a smooth warm sounding Bessel curve reminiscent of the finest vintage gear. Ruler flat from 10Hz to 40kHz and with virtually zero phase deviation the JDI delivers the natural pure sound of the instrument without artifact. By its no-power passive design the Radial JDI performs both high-to-low impedance conversion and signal balancing over a magnetic bridge that passes signal while rejecting stray DC voltage. This makes the JDI particularly adept at eliminating hum and buzz caused by ground loops.JDI ApplicationsJDI with Electric BassThe JDI is often selected for high output bass guitars. It is able to handle huge signal levels without distortion or artifact. On stage it sends the pure sound of the bass to the PA with minimal loading. In studio it is perfect for recording direct.JDI with Acoustic GuitarMost acoustic guitars have built-in preamps that can be peaky. The JDI naturally smoothes out the transients for a warmer tone. And because the JDI is able to handle huge transients it will not distort. This makes the JDI a great direct box for acoustic guitars.JDI with KeyboardsToday's digital keyboards are not only very dynamic some like digital pianos have a tremendously wide frequency response. The Radial JDI is able to withstand excessive signal levels at all frequencies without introducing distortion or phase shift.VideosThe Radial JDI explainedReverb Demo VideoHow to Break a Radial DIReviews Our RF noise tests proved the JDI to be flawless. The JDI Mk3 is a great choice when you need a DI box for a synth an amplifier or an instrument with active pickups. It will also work in reverse as a Reamp. By Scott Dorsey The best thing you can say about a direct box is that you forget it's there. The JDIs are transparent and noise free. They performed very well on every source I fed them including electric and acoustic guitar and bass. Even in an environment that's occasionally prone to grounding problems and noise the signal was ultra clean. By Emile Menasche Radial DI boxes sound - in a word - pure. Compared to these my old standby active DI has a thinner and harsher tone. No matter what type of signal I put through the Radial DIs sounded round and natural. Radial has done a superb job with these. By Mitch Gallagher With its Jensen transformer and excellent overload characteristics the JDI can handle any situation flawlessly. By Jim Rodgers The JDI is a winner from every angle. It's roadworthy it's feature packed and it sounds great! The Radial design team is obviously more than a bunch of white coats who only make it out of the lab once a week to watch Star Trek. They are a team who understand the needs of recording and sound reinforcement engineers and know how to design a product to meet these needs. By Russ Long I can say with no hesitation that you won't find anything out there offering better performance or more durability for the money. By Jim Miller Radial's JDI passive direct box is amazingly clean and noise free. Its design is a direct result of asking reputable names in the industry what would make up a great direct box. By John Albani The frequency response and phase response of the Radial JDI is excellent and the sound of the unit can only be described as completely transparent. This is an excellent passive DI box that will keep on working even after the band's van drives over it. My biggest regret is not finding out about Radial Engineering direct boxes sooner! We have transitioned through our move to individual monitor mixes from FOH to a dedicated monitor console to personal mixers and the Radial direct boxes have continued to work flawlessly through all of our upgrades. By David RobinsonArtistsAaron DessnerThe National The Radial J-Class DIs are easily the most reliable & consistent DI products available to the touring artist. Not only do they deliver a clean signal they also seem to provide a unique warmth which is essential to The National's sound. Alan ParsonsThe Beatles Pink Floyd Al Stewart The Alan Parsons Project The Alan Parsons Live Project band uses a large number of keyboards acoustic guitars and computer interfaces all of which require quality passive DIs. Our lives changed when we started carrying our own Radial DIs on the road and have never had a single issue or breakdown. We use the ProDI ProD2 and the JDI on bass. Our Radial Direct Boxes are rugged reliable and sound great - so much better than the competition - in fact there is no competition!
