OWNER'S MANUAL

The SDD-2000 is a new kind of digital delay that is designed to work
IUsed as a conven
tional delay ma
chine, the SDD-2000
can provide very long delay
times of up to. 4368ms. Up to
64 effects such as chorus,
flanging, doubling, and echo
can be programmed for rapid
access. MIDI program change
data can be used to select
stored effects.
N In the trigger over-
I dub mode, a foot
L switch, drum ma
chine trigger signal, MIDI tim
ing clock, or other signal can
be used to set the delay time,
making it easy to match the
tempo of the music.
The sequencer and
sampling modes al-
low audio inputs of
up to 4368ms to be recorded
and then reproduced when
desired. Coupled with a MIDI
keyboard (or other MIDI con
trol device) the sampled
sound can be "played" (like
on a sampling keyboard in
strument).

* About Modulation
Effects such as chorus, vibrato, and flanging are
produced by using the internal LFO (low fre

time.

About Feedback
Feedback or "regeneration" is a matter of taking
part of the signal coming out of the delay line and
feeding it back into the input to be processed
again. The amount of feedback and its phase help
establish the effect produced. With long delay
times, feedback level simply determines the
number of repeats or echoes. In flanging and
other short delay effects, the feedback level and
phase affect the tone color of the sound.
Runaway oscillation will occur if the feedback
level is set too high.
16 TIME x 4 Switch
This selects the "x4" mode which allows delay (or
recording/sampling) times of up to 4368ms. When
this is off, the maximum delay time is 1092ms.
An LED lights up to indicate 4 mode.
The x1 mode (the normal mode when x4 is not
selected) has superior high frequency response.
17TIME Switch
This is used to enable setting of the delay (or record
ing/sampling) time. In the x1 mode, the display
shows times of from 0. 0 to 1092ms; in the x 4 mode
it shows from 0 to 4368ms.
At settings of up to 10ms in the x 1 mode the display
gives fractional indications to the first decimal place.

18 PROG/PARA (RECCAL)
In the delay mode, this switches between allowing
"program change" and allowing editing of individual
parameters. In the sequencer and sampling modes it
allows "recording calibration." (For details, see the
section on the REC CAL function.)
19 WRITE Switch
This is used to store programs in memory. For
details see the section on "Writing a Program."

When used to set the delay time, this controller is
sensitive to how fast you turn the knob. It is designed
to change one step at a time when turned slowly,
and change in larger amounts when turned rapidly.

• Input Level Adjustment
• If the input level is too high it will cause distor
tion. If it is too low, it will reduce the signal-to-
noise ratio. Adjust input level so that the HEAD
ROOM indicator + 6dB LED lights occasionally
on maximum signal peaks.
• Remember to check and readjust input level
after changing feedback level. This is necessary
because the amount of feedback will change the
signal level within the circuitry.
• Set the ATTENUATOR to the correct position for
the signal source before adjusting input level.

NOTE
Modulation data is used to modulate sound record
ed using the SEQUENCER or SAMPLING mode. If
the sent data value is higher than the intensity
parameter value for a mode, then modulation can
be applied at higher than the set value. In this case,
modulation depth is smaller when compared with
those of the delay sound generated with the
DELAY or TRIGGER OVERDUB mode.

5 -MIX Output
This provides an out of phase mix of the direct and
effect sounds. Balance is determined in the same
way as for the + MIX output.
About Input/Output Level
Input and output level are at unity (one to one) in
the SDD-2000. Output level is the same as input
level.
Using the Outputs
The three output jacks can be connected
several ways to create stereo-like effects.
in
Example: 1.
Connect the DIRECT and + MIX outputs to sepa
rate amplifiers or separate mixing console chan
nels and pan them to opposite sides. Set the front
panel DIRECT volume control to "0" (so that only
the effect sound appears in the + MIX output). With
short delay times this gives a rich stereolike sound.
With long delay times the sound appears to shift
from one side to the other.
Example: 2
Use + MIX and - MIX connected to separate ampli
fiers or separate mixing console channels and pan
them to opposite sides. The out-of-phase effect
component of the - MIX output creates a very
spacious sound. Especially good for chorus, flang
ing, and similar effects.
CONTROL SECTION
The jacks in this section are used with foot switches, drum nnachines,
MIDI signals, and so on for control of various SDD-2000 functions.
6 BYPASS Jack
For foot switch control of the BYPASS function. Us
ed the same way as the front panel BYPASS switch.

FEATURES & FUNCTIONS
7 REC CANCEL Jack
When a foot switch that is connected to this jack is
depressed, the SDD-2000 switches to the REC
CANCEL mode. This leaves the effect sound that is
present at the instant the foot switch is depressed
and switches the input signal to bypass the delay cir
cuitry. While REC CANCEL is on, the front panel
REC CANCEL LED illuminates.
8 PROGRAM UP Jack
The selected program number is advanced each
time a foot switch connected to this jack is depress
ed (in the delay mode).

9 REC Jack
For foot switch operation with the same function as

10 TRIGGER Jack .
—For a trigger signal input from a drum machine or
foot switch.
This triggers playback of sampled sounds (in the
sampling mode) or sets the delay time (in the trigger
overdub mode).
The front panel TRIG LED illuminates every time a
trigger signal is received.
Foot Switches to be Used with Control Jacks
Foot switches to be used with these control
jacks should be the type that is on during the
period the foot switch is depressed. Such foot
switches include the Korg PS-1 and S-2.
