Radial JDV

Active Direct Box, Preamp, & Input Switcher


About this item



The Radial JDV is a premium active direct box and preamp that features two inputs that can handle almost any source, from active and passive instruments to microphones and piezo transducers.

  • 100% discrete class-A active direct box
  • Combine instrument and microphone inputs and phase-align
  • Drag Control load correction for natural tone
  • Huge 30-Volt rails for exceptional headroom

The direct box that does it all

The JDV makes no compromises on available features or audio quality, opting instead to provide anything you could ever ask of a high-performance DI box. Designed for studio recording or pro-touring applications, the JDV provides exceptional headroom with massive 30-Volt internal rails, resulting in virtually zero distortion and producing an incredibly transparent and natural representation of your instrument. It has two inputs that can be individually selected or blended together and phase-aligned, with the ability to handle condenser mic’s, piezo transducers, and the outputs of effectively any instrument. The balanced output can be set to mic or line-level, allowing you to bypass an additional preamp and connect directly to a recording interface for pristine studio recordings.

The Radial JDV is unlike any other direct box made today. The absence of phase canceling negative feedback in the front end combined with 100% discrete class-A electronics results in an astonishing clarity that is unmatched. The addition of switchable Jensen isolation transformers adds yet another dimension by adding natural compression when pushed into saturation. The resulting tone can be observed in the FFT graph showing a warm cascade of even harmonics that will please even the most demanding audiophile.
