Product Description

zZounds is an
authorized Radial dealer

The Radial JDI is a passive direct box designed to handle extreme signal levels without distortion of any kind. Unlike an active DI that is limited by the buffering amplifier's rail voltage, the JDI employs a Jensen audio transformer as the engine. Jensen transformers are legendary in their ability to gracefully handle transients while 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.

The 100% passive circuitry inside the JDI is incredibly efficient. The transformer performs both high-to-low impedance conversion and signal balancing at the same time with minimal loading and does so without any power whatsoever. The transformer also introduces 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.

Features include input and throughput 1/4" connectors, -15dB input pad, ground lift, and 180o degree polarity reverse to help phase align the instrument with the PA. A secondary circuit is added for direct interfacing with high output devices such as guitar or bass amp loudspeakers plus a unique merge function allows stereo sources such as keyboards to be summed mono, saving valuable input channels.

Built tough to handle the abuse of live touring, the JDI features a 14-gauge steel I-beam inner frame and a unique book-end outer shell. The innovative design eliminates stress on the PCB, reducing opportunity for solder joints to go 'cold' while the outer shell creates a protective zone around the switches and connectors. The steel casing resists noise-causing electromagnetic pollution and the transformer's sensitive inner workings are further protected from magnetic fields with a mu-metal can. This ensures the signal transfer is quiet and free from hum.

These combined features have made the Radial JDI the most popular passive direct box in professional touring and an excellent choice for instrument interface in the studio!

The Radial JDI... the world's finest passive direct box.

"Stop searching... your DI troubles are solved."

Sound: I used this on my 6 string bass... WOW! I was having a bit of a hate on for the bass as I felt it was a bit lack luster going through my other passive DI box. This was different... no lie my B string sounded tighter, and the pups on the bass sounded clearer. I will not let this DI box go - EVER! Feature: There's a number of cool things it can do... but I'm just DI'ing it no need yet for the other bits... Ease of Use: plug-n-play not pray Quality: TANKS should be built this well... Value: I'd pay more but I'm glad I didn't have to. Manufacturer Support: They're Canadian... so polite. The Wow Factor: I want the JDI rack for my synths now Overall: The search is over.

Written by one of our gear experts! "Accept no substitutes."

Sound: Fantastic, clean, and accurate. Doesn't get in the way of your instrument and its voice, rather brings out its true sound and keeps it alive and well all the way to your ears. Feature: Between the PAD option that doesn't take away from your sound, the ground lift, and the merge input option, what more could you ask for? This one has all the options and features you could ask for in a DI, and spells them all out very clearly on the case. Ease of Use: Plug it in. Play. It's that simple. This DI can be as simple or as complicated as you need it to be. Quality: Built like a tank and always ready to go. Seriously, Im sure this thing could take a literal beating and still preform like nothing happened. If the SM58 has a DI equivalently for durability, this would have to be it. Handles whatever you can throw at it and then some with losing quality. Perfect for taking on the road too. Value: The absolute best for the price. If it cost more I would still buy it. Manufacturer Support: Haven't had to deal with support for this product, and something tells me I won't need to either. The Wow Factor: Great layout, very clearly labeled, lets you know exactly what each button and feature does, while put together in a quality package. Overall: Overall, the best bang for your buck. It's sometimes hard to realize how much a quality DI can truly add to your sound until after you hear it. This is a purchase you will not regret!
