From Radial Engineering
- 100% discrete class-A active direct box
- Feed forward design – no negative feedback
- Drag Control load correction for natural tone
- Huge 30-Volt rails for exceptional headroom
The Radial JDV is arguably the very best direct box ever made. It is able to handle any type of instrument with ease, reproduces the sound with the utmost accuracy and least coloration, and is equipped with all of the connectivity you will ever need whether you are performing on stage or recording in the studio.
The active design begins with 100% discrete class-A circuitry for absolute signal purity while eliminating troublesome zero-cross distortion. But unlike all other buffering amplifiers, the JDV does not employ any phase-cancelling negative feedback loops to stabilize the circuit. Instead, a tube-like configuration with proprietary stabilizers delivers the true sound of the instrument without artefact or hype.
To address electric bass and guitar, the JDV is equipped with Drag Control that enables you to correct the load of the instrument as if connected directly to an amplifier. For piezo instruments, the input can be switched to 4meg-ohms to eliminate squawk. And with 30 volt internal rails, even the most dynamic digital sampler or active bass can be handled with ease. Features separate outputs for the PA, monitors, amps and tuner making it stage and studio ready.
How does it sound? When one musician proclaimed: The JDV is the best sounding DI I have ever heard. We replied: No… it's your bass… you've just never heard it before.
The JDV… There is no other like it anywhere or at any price.
The Radial JDV is unlike any other direct box made today. The absence of phase cancelling negative feedback combined with 100% discrete class-A electronics results in an astonishing clarity that is unmatched. The trade off is of course a slight reduction in signal to noise. The benefits however result in a warm cascade of even harmonics that will please even the most demanding audiophile.
