Radial JDVmk3 Super DI

•  Class-A feed forward design
•  Huge 30-Volt internal rail voltage
•  Innovative Drag control
•  Variable impedance to 3.9 Meg-Ohms
•  Unique zoned design concept

The Radial JDV Mk3 is arguably the most advanced and sonically superior direct box made today. With 100% class-A circuit and a 30-Volt internal rail voltage, the JDV combines exceptional sonic quality and unmatched dynamic handling for the most natural and uncolored sound possible.

Designed as a creative tool, the JDV introduces a concept of ‘Zones’ with choice of two inputs, four instrument amplifier outputs, and a unity-gain transformerless output.

Features include Drag control for precise pickup load correction, 3.9 meg-ohm input impedance for piezo pickups, hi-pass and lo-pass filters, full LED status indicators, polarity reverse and all of the other features one would expect from a Radial DI.

The Radial JDV Mk3 is designed for use in both the studio and live performance and is suitable for all instruments where added reach is required and retaining the original sound of the instrument without distortion or coloration is paramount.

JDV Development

You’ve been hearing the JDV for years! The original JDV was a staple at Little Mountain Studios and used on these highly successful albums.

The original JDV Mk1.

Today's JDV Mk3 'Super DI'.

The Radial JDV Mk3 represents a milestone in new direct box technology by introducing the concept of creative zones for the musician and engineer all the while elevating the sonic expectations beyond any other direct box produced today. They call it the Super DI.

The Radial JDV was originally developed by John Vrtacic in the 1980s who at the time was the Chief Technical Engineer for Little Mountain Studios in Vancouver, British Columbia. Little Mountain was ‘home’ to producers Bruce Fairburn and Bob Rock and their astonishing number of hit records from artists like Aerosmith, Bryan Adams, ACDC, The Cult, Metallica, Bon Jovie, Loverboy and so many others. The huge Little Mountain ‘drum and bass sound’ became famous with millions of albums sold worldwide.

In 1997, Ron ‘Obvious’ Vermulin, Chief Technical Engineer at Bryan Adam’s Warehouse Studios (Ron also designed the Mutt Lang/Shania Twain studio) was asked to test the 1st generation Radial JDI passive direct boxes against a number of ‘popular’ DIs and it was from these tests that the Radial Green Report was produced. While testing the Radial JDI, Ron decided to run the same tests through one of the original John Vrtacic JDV direct boxes. Although the Radial JDI faired better than all other commercial units, the hand-made JDV was clearly the best. Ron suggested they contact John and build a commercially viable version of the JDV.

The 1st generation Radial JDV gained a strong following due the clarity of tone. This was supported with it winning comparative tests in influential magazines such as Mix, Recording and Bass Player. The JDV became firmly cemented in the industry when influential artists like Tony Levin, Will Lee and Alain Caron began using it on their bass tracks. The first generation JDV employed a battery as part of the power supply circuit along with a switching power supply and surface mount technology. This was done in an attempt to reduce the size and power consumption. Although the system worked well, many users did not like to have to keep the internal batteries charged so in 2001, the decision was made to update and redesign the JDV.

The Radial JDV Mk3 is our most advanced DI ever. They call it the Super-DI because it combines the amazing sound of the original with a significantly improved power supply, a very low noise floor and a tremendously useful feature set.
