OPERATION
The following instructions will describe how to operate the SDP-20. For further detail on specific functions and controls, also consult the
descriptions above (CONTROLS AND CONNECTIONS) as needed.
GETTING STARTED
Set the INPUT VOLTAGE SELECT SWITCH (15) for either
~115V(60Hz) or ~230V(50Hz) AC power. Attach the power cord
and plug it in.
Connect the Input and Output signals from the SDP-20 to your
audio system with the appropriate XLR balanced or 1/4"
unbalanced INPUT and OUTPUT JACKS (20 - 27), depending on
the type of cable and connectors you’re using.
Turn the POWER SWITCH (13) On. You will see the previously
selected preset Program number on the PROGRAM/VARIATION
DISPLAY (6).
SELECTING AN EFFECT
There are 255 preset effects. Use the EDIT/SAVE/LOAD/EQ
SELECTOR & 5KHZ EQ SELECT KEY to select the NORMAL
MODE. This MODE indicated on the MODE DISPLAY (6b) when
all the 4 LEDs are off. See PRESET PROGRAM LIST, page 8.
Chose between the main effect type desired using the UP/LEFT &
250HZ EQ SELECT KEY (7) to choose the previous effect type or
the DOWN/RIGHT & 1KHZ EQ SELECT KEY (8) to select the
next one. There are 8 main effect types that can be selected and
the one chosen will light up the corresponding LED on the
EFFECT TYPE DISPLAY (4). Select the desired choice of the 255
presets by rotating the VALUE ADJUSTMENT CONTROL (12)
clockwise to select a higher number effect and counterclockwise
for a lower number effect. The EFFECT TYPE DISPLAY (4) and
the PROGRAM/VARIATION DISPLAY (6a) will indicate the effect
type and effect number selected. Note that all effects selected are
preset to their default values. Effect parameters can be edited.
