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 DISPLAY indicates “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.

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
