Radial Engineering JDV-Pre – No Longer Available

Class-A instrument preamp with unique features
MFR# R700 0120

Product Description

The Radial Engineering JDV-Pre is one of the eight modules designed to be comprise the Radial Workhorse Rack and Mixer System that combines the popular 500 series platform with an incredibly flexible patching system to let you create the ultimate studio environment.

The Radial JDV-Pre is a unique preamplifier designed specifically to capture the natural tone and distinct character of the instrument. This may sound like another 'marketing line', but unlike mic preamplifiers that are centered on 'the microphone', the JDV-Pre is completely focused on the various types of pickups used while transferring the signal without introducing distortion or artifact of any type.

The design begins with a 100% discreet class-A amplifier for optimal signal transfer. But unlike all other amplifier designs, the JDV-Pre's front end is completely void of the negative feedback loops normally used to stabilize the circuit. This revolutionary design eliminates the use of phase-cancellation which inevitably degrades the signal. This is augmented with Drag Control load correction that allows the engineer to optimize the load on the instrument pickup for the most natural rendering.

The quest for perfection does not stop there. When the impedance is set for piezo pickups, the JDV-Pre remains unbelievably quiet. Accustate gain control not only allows complete freedom over the signal path, but retains the signal-to-noise ratio at all levels. Acoustic instruments are further advantaged with a fully variable high-pass filter that gently rolls of the low end to eliminate troublesome body resonance while allowing each instrument to sit more comfortably in the mix. To address instrument microphones, the JDV-Pre features a transformer coupled balanced mic input with available 48V phantom power for condenser microphones. Connection is made via standard 500 series rack XLR input.

Features:

  • 100% discrete class-A instrument and mic preamp
  • Feed forward front-end, void of negative feedback
  • AccuState gain control for low noise at all levels
  • Variable low frequency cut for acoustic instruments

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
