The Radial ProD8 is a high density 8 channel passive direct box designed specifi cally for key­board systems in pro touring environments. Each channel features dual ¼” inputs that are pre­merged using a resistive circuit. The dual inputs may be used to sum a stereo signal to mono or
for redundant back-up systems in case of equipment failure. A built in effects loop uses a TRS
insert jack allowing the dual inputs on each channel to share an external effects device. Local
monitoring for each channel is provided via the parallel thru-put connector.

ProD8 is equipped with eight custom wound Radial transformers, each encapsulated inside a
nickel mu-metal can to reduce noise and distortion caused by outside magnetic fi elds. To accom­modate high output instruments and line level equipment, a -15dB pad is provided on the input
panel. XLR outputs are equipped with polarity reverse, ground lift and chassis ground switches
to help interfacing with stage and studio environments.

For added fl exibility, reversible rack ears allow either panel to face front. The ¼” jacks may be
positioned inside the rack to interface with sound modules and samplers or outside the rack for
typical keyboard set-ups. The ProD8 is the perfect interface for demanding keyboard systems.

A/B DUAL INPUTS sum
stereo to mono or may be use
for redundant backup gear.

LIFT switch disconnects pin 1
at the XLR output to eliminate
noise caused by ground loops.

GROUNDING LUG
Two threaded screw mounts are
provided for custom grounding.

PIVOTING RACK EARS
your choice which panel
faces the front, ¼” or XLRs.

-15dB PAD reduces input
level for ultra-hot signals
such as CD players.

180° switch reverses the
signal polarity to correct
two out-of-phase signals.

LOOP built in effects loop for
each channel works like an
“insert” on a console.

ISOLATED connectors
are made from rugged
glass-fi lled nylon.

PRE/POST EFX internal switch
allows the THRU output to be
pre or post the effect-loop.

CHASSIS GROUND internal
switch allows individual ground
paths for each channel.

RADIAL TRANSFORMERS
are sealed in a mu-metal
shield to block EMI noise.

THRU jack connects
to on-stage keyboard
mixer or amps.

WELDED 14 GAUGE STEEL
construction is tough to handle
abuse on the road.

1RU compact
rackmount with
six inch rack depth.

Keyboard Rig

Flexible control center for large keyboard rigs.
Distribute, balance and process eight signals in
one rack space.

Live Backing Tracks

ProD8 is perfect for interfacing a digital multitrack
into a live performance. Redundant “B” inputs can
be used for a pre-wired back-up machine.
