SCR-DI Bass DI with Scrambler™ Overdrive
SCR-DI Bottom Panel Features
BOTTOM PANEL ACCESS
A –15 dB pad jumper is located inside
the bottom of the pedal. This is also
where the 9V battery is housed.
Removing the bottom is easy. Simply
start by placing the pedal top down
on a soft, dry cloth.
Each of the four rubber feet located on
each corner also doubles as a screw.
Remove the feet/screws by turning
them counter-clockwise. Be sure to
keep them in a safe place as you will
need them again!
22. 9V BATTERY
The SCR-DI may be powered by 9V
battery instead of using a power supply.
As seen in the illustration above right, it
tucks in nicely inside a compartment of
the circuit board next to the edge of the
pedal.
NOTE: Unplug the input cable when
not in use, as the 9V battery will drain
(and eventually die).
NOTE: When replacing the bottom of
the pedal, line up the rectangular foam
piece over the battery and the metal
protrusion by the power connector.
Turn the feet/screws clockwise to affix
to the bottom to the pedal.
23. –15 dB PAD JUMPER
Moving the –15 dB pad jumper reduces
the input signal by 15 dB and compen-
sates for higher output sources. This
attenuation is suited for use with basses
that have active electronics or high-
output pickups.
There are only two possibilities.
The jumper can be on:
Pins 1-2 [Normal – default] or
Pins 2-3 [15 dB pad]
Ok, ok...there could be no jumper,
but that just sets the pedal to its
normal/default [pins 1-2] setting
(with about 1/2 dB loss).
Referencing the diagram above, slide
the jumper out, left to right, then back
in, right to left, on the pins that you
want to use for your instrument.
NOTE: When replacing the bottom of
the pedal, line up the rectangular foam
piece over the battery and the metal
protrusion by the power connector.
Turn the feet/screws clockwise to affix
to the bottom to the pedal.
