To ensure years of enjoyment from your NADY AUDIO SDP-20, please read and understand this manual thoroughly before
using the unit.
INSPECTION
Your SDP-20 was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using
your unit, carefully examine the packaging and all contents for any signs of physical damage that may have occurred in transit.
(Note: Nady Systems is not responsible for shipping damage. If the unit is damaged, do not return to us, but notify your dealer and the
shipping company immediately to make a claim. Such claims must be made by the consignee in a timely manner.)
CONTENTS:
•Instruction manual
•SDP-20 (verify that the unit’s serial number is same as shown on shipping carton)
•AC Power cord
•Warranty Card
RACK MOUNTING
The SDP-20 fits into one standard 19" rack unit of space (1 3/4"). Parts of the unit can become very warm during use. This is normal
during operation. Care should be taken to ensure that there is enough space around the unit for cooling (at least 12”or 30cm). Do not
place the SDP-20 on high temperature devices such as power amplifiers, etc., or the unit may overheat in operation. Also, do not
place the unit on speakers as this may cause them to move and/or fall due to speaker vibrations.
Although the unit’s chassis is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high fields of RF
and EMI should be avoided.
POWER CONNECTION
The SDP-20 has an internal power supply and is designed to operate from an external AC source. Power requirements for electrical
equipment differ from area to area. Be sure to confirm that the voltage selected by the voltage selector switch on the back panel is
proper for your area (120VAC/60 Hz or 230VAC/50Hz) per the information below:
Europe (except UK): 230V, 50Hz
UK and Australia: 240V, 50Hz
USA and Canada: 120V, 60 Hz
For other areas, please check with local authorities.
When ready to operate, plug the AC cord into the power source. Make sure that the unit is turned off before connecting to the AC
power source to avoid possible loud transients which can damage your speakers or your ears, especially when monitoring with
headphones.

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.
(See CUSTOM EFFECTS, page 7)

OPERATION
An optional external foot switch can also be connected to the
PROGRAM INCREMENT FOOT SWITCH (16) jack and used to
step through the preset programs incrementally one after the
other. Contact your dealer or the NADY SERVICE DEPARTMENT
(see back page of this manual) for availability.
BYPASSING EFFECTS
Bypass the effects by pressing the front panel BYPASS SWITCH
(10). The PROGRAM/VARIATION DISPLAYindicates “OFF”when
in bypass mode and all the LEDs in the EFFECT TYPE DISPLAY
(4) and PARAMETER DISPLAY (5) will be off. When in BYPASS
(effects off) MODE, the EQ MODE is not off and EQ parameters
can be edited.
An optional external foot switch can be connected to the BYPASS
FOOT SWITCH (17) jack and used to toggle the bypass mode
ON/OFF successively. Contact your dealer or the NADY SERVICE
DEPARTMENT (see back page of this manual) for availability.
ADJUSTING LEVELS
Adjust the INPUT GAIN CONTROL (1) for the highest setting
without the red top L/R LED indicators of the INPUT LEVEL
DISPLAY (3) staying on continuously. Occasional flickering of
these red LED indicators is normal.
Adjust the OUTPUT LEVEL CONTROL (2) for the optimum level
and minimum noise for driving the connected components of your
sound system.
AUDIO EQUALIZER
The equalizer settings are independent of the preset program or
custom program settings. The value of each frequency band is
stored in non-volatile memory and is recovered when the unit is
turned on. Values for each band can be set between 1 and 128
with the center at 64. For each effect selected, the EQ parameter
can be edited and saved.
Select EQ mode using the EDIT/SAVE/LOAD/EQ (9) key.As you
press the KEY (9) the corresponding LED will light and you will
see the MODE DISPLAY (6b) change between functions. Select
“EQ”. The UP (7) and DOWN (8) buttons will select the specific
EQ Band desired (250Hz, 1KHz, 5KHz, 16KHz).Adjust the level
with the VALUE ADJUSTMENT CONTROL (12) (64 = 0dB, 127 =
+12dB and 0 = -12dB). Press BYPASS/ENTER KEY (10) to
confirm changes and return to NORMAL MODE. (Note that if the
unit is left non operational for a while, it will enter NORMAL MODE
by itself).
CUSTOM EFFECTS
Custom effects are modified preset effects. There are 20 locations
for storing custom effects. The Save and Load functions of the
EDIT/SAVE/LOAD/EQ (9) key provide write and read of the
custom non-volatile memory location.
To capture and edit the preset value:
Choose a preset effect similar to the desired effect. Cycle
the EDIT/SAVE/LOAD/EQ (9) key to the “EDIT”mode. The
UP (7) and DOWN (8) buttons will select the variable field:
Volume, Delay, Feed Back, Time, Density, or Filter. Use the
VALUE ADJUSTMENT CONTROL (12) to modify the
variable to the desired sound. The PROGRAM/VARIATION
DISPLAY (6a) will indicate the corresponding value. Note
that the edited parameters can apply to the present state of
the effect selected or saved as custom values.
To save the modified values in a custom location:
Cycle the EDIT/SAVE/LOAD/EQ (9) key to the “SAVE”
mode as indicated by the MODE DISPLAY (6b). Use the
VALUE ADJUSTMENT CONTROL (12) to select the
custom storage location 1 thru 20 as indicated by the
flashing PROGRAM/VARIATION DISPLAY (6a). Press the
ENTER (10) key to store the custom effect and return to
the NORMAL MODE. (
Note that if the unit is left non
operational for a while, it will enter NORMAL MODE by
itself).
To recall a custom effect:
Cycle the EDIT/SAVE/LOAD/EQ (9) key to the “LOAD”
mode as indicated by the MODE DISPLAY (6b). Use the
VALUE ADJUSTMENT CONTROL (12) to select the
custom storage location 1 thru 20 indicated by the flashing
PROGRAM/VARIATION DISPLAY (6a). Press the ENTER
(10) key and return to the NORMAL MODE. (Note that if
the unit is left non operational for a while, it will enter
NORMAL MODE by itself).
Auto-save function:
If the unit is turned off after changing parameters or values
during operation (including selected effects, effect
parameters, EQ values, etc.), its auto save function will
automatically retain these changes for the next time the
unit is powered on, even if the user does not save them.
REMOTE CONTROL USING MIDI
1) Use the DRFX.exe application on a PC. The application
controls the sound card “Game Port”, 15 pin D-sub connector.
The application can be downloaded from the Nady.com web
site.
2) Connect the PC to the SDP-20 MIDI IN connector via
interconnect cable. The MIDI interconnect cable is available
from Nady.
3) Push the front panel switch MIDI (11) to allow remote control.
4) Launch the application on the PC.Adjust the software slider
controls for desired sound.
