Radial Engineering JDV Dual-Input Active Direct Box with Class-A Audio Circuit
Product Introduction
The Radial Engineering JDV is widely recognized as one of the most advanced active direct boxes ever created. Combining the functionality of a premium active DI box, microphone preamp, input switcher, and signal blending system, the JDV delivers unmatched audio performance for professional recording studios, live touring productions, worship venues, and broadcast facilities.
Built around a 100% discrete Class-A circuit design with massive 30-Volt internal rails, the JDV provides extraordinary headroom, virtually zero distortion, and an exceptionally transparent signal path. Whether you're connecting guitars, basses, keyboards, piezo-equipped acoustic instruments, or condenser microphones, the JDV preserves every nuance of your performance with remarkable accuracy.
Product Description
Unlike conventional direct boxes, the Radial JDV is engineered to be the ultimate signal management solution for demanding audio professionals. Featuring dual independent inputs, the JDV allows users to connect and blend magnetic pickups, active instruments, piezo transducers, and condenser microphones simultaneously.
Its innovative Drag™ Control load correction technology recreates the natural interaction between passive pickups and amplifiers, delivering a more authentic and musical tone. The selectable 10 Mega-Ohm input perfectly matches piezo pickup systems, ensuring optimal frequency response and maximum sonic detail.
With 30-Volt internal rails, the JDV offers significantly greater headroom than standard active DI boxes, eliminating clipping and preserving dynamics even with high-output instruments. The transformer-isolated Jensen outputs further ensure pristine signal transfer while reducing noise, hum, and interference.
For studio applications, the balanced output can be switched between microphone and line-level, allowing direct connection to audio interfaces without requiring additional preamps. This results in cleaner recordings, reduced signal degradation, and exceptional audio quality.
Built to Radial's legendary standards, the JDV is designed to withstand years of professional use in studios, touring rigs, and permanent installations.
