The Radial JDV Super DI redefi nes the direct box by introducing three zones; two
selectable inputs, three instrument outputs, a tuner-out and a balanced output for the
console. These zones allow the musician to work within his own unique environment
to spur on the creative process with new sounds, while providing the engineer with the
ultimate in sonic performance.
Open up the JDV and you will fi nd 100% discreet, over-sized components (no opamps). The JDV combines our unique feed-forward Class-A circuit (no feedback loops)
with extraordinary 30-Volt internal rails to produce unmatched sonic performance where
maximum headroom, ultra-low harmonic, phase and intermodulation distortion is achieved.
The result is signifi cantly greater detail, minimal coloration, and improved depth and
spectral imaging. To capture the natural essence of the instrument, the JDV is equipped
with Drag™control, a unique load correction circuit that reintroduces the natural tone that
is lost when connecting to buffered circuits. A pad on the output ensures the JDV will not
overload your mixer. As a unity gain device, the JDV will accept huge input levels and send
them through without restriction.
The JDV’s ultra-low noise signal path makes it possible to present an instrument with an
unprecedented 3.9 Meg-Ohm input for use with the more demanding piezo pickups. The
Radial JDV is without question, the fi nest studio direct box made today.

Effects
3 LED STATUS INDICATORS
for power, signal present and clip
overload.
FILTER high-pass fi lter reduces
excessive bass for more clarity.
Eliminates run-away resonant
feedback from acoustics!
Low-pass fi lter gently rolls off high
end and reduces noise from older
instruments.
A / B INPUT SWITCH selects
between the two instrument
inputs for fast changes.
DRAG™ CONTROL is used
to retain the natural feel of the
instrument on the active auxiliary
outputs by correcting the load.
DRAG SWITCH selects between
ultra-high 3.9 Meg-Ω input impedance and Drag control.
CABLE LOCK assures against
accidental power loss.
-15dB OUTPUT PAD prevents
clipping at mixer input.
GROUND-LIFT disconnects the
ground path at the XLR output.
42V EXTERNAL DC POWER
SUPPLY with cable lock.
POLARITY REVERSE fl ips pin-2
and pin-3 on the XLR output.
XLR OUTPUT balanced 600Ω
mic-level out for long cable runs.
Amplifi er
SPEAKER INTERFACE extra -30dB
pad allows JDV to be used between
amplifi er and speaker cabinet.
