Radial JDV Details The Radial JDV Mk3 is arguably the most advanced and sonically superior direct box made today. With 100% class-A circuit and a 30-Volt internal rail voltage, the JDV combines exceptional sonic quality and unmatched dynamic handling for the most natural and uncolored sound possible.
Designed as a creative tool, the JDV introduces a concept of ‘Zones’ with choice of two inputs, four instrument amplifier outputs, and a unity-gain transformerless output. Features include Drag control for precise pickup load correction, 3.9 meg-ohm input impedance for piezo pickups, hi-pass and lo-pass filters, full LED status indicators, polarity reverse and all of the other features one would expect from a Radial DI.
The Radial JDV Mk3 is designed for use in both the studio and live performance and is suitable for all instruments where added reach is required and retaining the original sound of the instrument without distortion or coloration is paramount.
Radial JDV Features
Class-A feed forward design
Huge 30-Volt internal rail voltage
Innovative Drag control
Variable impedance to 3.9 Meg-Ohms
Unique zoned design concept
Instrument Input Zone
LED Status indicators include system on, signal present and peak level overload.
80Hz high-pass filter reduces excessive bass for more clarity. Elliminates run-away resonant feedback from acoustics!
7kHz low-pass filter gently rolls off high end edge and reduces noise and hiss from older instruments. Very musical!
Vary-Z switch selects between ultra-high 3.9 Meg-Ohm input impedance and Drag control for load correction.
Drag Control is used to retain the natural feel of the instrument on the active auxiliary outputs by correcting the load.
A or B input switch selects between the two instruments inputs for fast changes.
Musician's Connection Zone
Heavy-duty baked enamel finish for durability and great looks! 14-gauge steel makes it impossible to break!
Speaker interface option introduces a -30dB input pad. Must be connected in parallel w/speaker.
Inputs A & B are selected using front panel switch for quick. noiseless instrument change.
Direct thru-put passive output connects to the instrument amplifier.
Auxiliary outputs A & B are used for additional amplifiers, stereo rigs or effect devices. Very flexible!
Tuner output removes tuner from audio signal path for optimum audio performance.
No-slip full bottom pad reduces mechanical vibration, improves electrical isolation & stops sliding!
Engineer's Zone
Unique book-end design creates a protective boundary around the switches and connectors.
Strain releif for power supply cable.
XLR balanced mic level outputcan drive runs of up to 1000 feet without appreciable noise.
Polarity reverse switch flips the polarity from the AES standard Pin-2 to Pin-3 on the XLR and is used when combining sounds that may be out of phase.
-15dB pad: The JDV rail voltage is so huge, we put a -15dB pad at the output so that it will not overload your mixer.
Ground-lift disconnects the ground path at the XLR output. This would be used when a ground connection is made at the input side such as with a keyboard.
42V external DC power supply with cable lock to assure the JDV will not accidentally lose its power connection.
