ProD8 Owner’s Manual
True to the Music
¼" PHONE PANEL
REVERSABLE RACK EARS
allow you to setup the ProD8
with either the ¼" jacks or XLR
connectors facing front.
IN-A/B
dual inputs on each
channel auto-merge to mono.
THRU
parallel thru-put connects
to on-stage amp or mixer for
personal monitoring.
LOOP
each channel features
an effects-loop on a TRS jack.
Works like an insert on a mixing
console.
-15dB PAD
reduces the input
level by -15dB to prevent
overload from high output
devices.
XLR PANEL
XLR OUTPUTS
are balanced
600 ohm, mic-level and 100%
transformer-isolated to prevent
ground loops.
LIFT
disconnects pin-1 on the
XLR output to isolate ground via
the transformer.
180°
reverses pins 2 & 3 on the
XLR inverting the signal polarity
to correct out-of-phase signals.
INTERNAL
WELDED 14-GUAGE STEEL
rackmount enclosure is finished
in durable baked enamel.
RADIAL TRANSFORMER
with linear frequency response
from 20Hz to 18KHz for natural
sound. Mu-metal shield blocks
electromagnetic interference.
PRE/POST EFX
internal switch
allows the THRU output to be
pre or post the effects-loop.
Factory set to post effects-loop.
CHASSIS GROUND
internal
switch allows individual ground
paths for each channel.
Factory set in the lifted position.
MIILITARY-GRADE
double-
sided PCB is bolted to steel
standoffs for toughness.
ISOLATED CONNECTORS
extremely tough glass-filled
nylon for true channel isolation
from chassis ground.
