Radial JDV MKV Class-A DI w/ Dual Inputs - Your Gateway to Exceptional Sound
All-in-One Audio Powerhouse
This Radial JDV is not just any direct box. It's a premium active direct box, preamp, and input switcher rolled into one. It can handle almost any source you throw at it, from active and passive instruments to microphones and piezo transducers.
Uncompromising Performance
Designed for studio recording or pro-touring, the JDV offers top-notch features and audio quality. With massive 30-Volt internal rails, it provides exceptional headroom, virtually eliminating distortion and delivering a transparent, natural sound of your instrument.
Versatile Input Options
It has two inputs that can be individually selected, blended, and phase-aligned. Connect two instruments and switch between them using the optional JR-2 A-B footswitch. Combine the sound of an acoustic guitar's piezo and mic, or switch seamlessly between electric and upright bass. The balanced output can be set to mic or line-level, bypassing an extra preamp for pristine studio recordings.
Unique Sound Characteristics
The absence of phase-canceling negative feedback and 100% discrete class-A electronics result in astonishing clarity. Switchable Jensen isolation transformers add natural compression when pushed into saturation, creating a warm tone that audiophiles will love.
