Backup battery The SDD-3000, once programmed, keeps the program intact even when the power switch is turned off. A built-in battery energizes the programmer when the main power is turned off. Another advantage is that the battery is charged when the main power is on. However, if the unit is not used for over 3 months, the battery could lose its charge and programs could be accidentally erased. -
Page 3: Major Features
MAJOR FEATURES Offers a large number of versatile, high-quality effects such as flanging, doubling, chorus, vibrato, Doppler effect, slapback and echo, at the push of a button. Over 1 second delay range (0~1023 milliseconds) standard at full 17 kHz delay bandwidth. Low delay path distortion (0.03%, typical) and excellent 94 dB effect dynamic range (88 dB effect SIN ratio), without compander 'breathing' effects, through use of proprietary 13 bit audio conversion technique. -
Page 4: Features And Functions
FEATURES & FUNCTIONS This part of the Owners Manual is intended to provide an overview of the features & functions of the SDD-3000. Further information is contained with USING THE SDD-3000 and WHAT IS A DIGITAL DELAY. 1. Input Section The input section accepts a variety of audio signals from the outside world and adjusts their level for best noise and distortion performance. - Page 5 This switch selects the basic gain an input impedance of the input stage. It should be set to a position matching the output level of the equipment feeding the SDD-3000, in order to achieve the best dynamic range. Equipment ranging from electric guitars to professional studio mixers can be used with excellent results.

Page 6: Regeneration Section
PROGRAM UP and DOWN Footswitch Jacks (Rear Panel - ?) Two footswitch jacks are provided to allow remote program selection This capability is especially useful for live performance. Footswitches should be Korg PS-1, S-2, or other momentary, normally open type that switches to ground when depressed. -

However, this does allow you to solo aver a short musical phrase. An optional footswitch (Korg PS-i, etc.) may be connected to the rear panel HOLD jack for remote control of the HOLD function. The HOLD button may still be used with the footswitch connected 4. -
Page 8: Effect Section
The DELAY MOD input allows an external Control Voltage to vary the Delay time setting. This control voltage should be in the range of O - 5 volts; the higher the voltage, the shorter the Delay time. A KORG MS-01 or MS-04 Pedal or other voltage source may be connected. -

The ATTENUATOR switch selects the basic or "nominal" level of the VARIABLE Output jack. It should be set to a position matching the input require ments of the equipment connected to the SDD-3000. in order to achieve best noise &... - Page 10 The -MIX Output provides the difference (out of-phase mix) of the Direct and Delayed signals at all times. The relative balance between Direct & De layed signal IS determined by the LEVEL BALANCE control.

Page 11: Setup And Connections
NOTE: All connections ere made using standard 1/4" phone jacks. Guitar cables or standard patch cords may be used. NEVER connect a speaker or headphone output from an amplifier to an" jack on the SDD-3000, or serious damage may be caused to either or both units. - Page 12 1) Monaural Outputs A monaural output is typically used when two amplifiers or a stereo mix is not available. The SDD-3000 has two monaural (mono) outputs; each provides a variable mix of the Direct and Delayed signals. a)The front panel VARIABLE Output should be used for most purposes. The nominal level at this jack is only...

Page 13: Using The Programmer
It may sometimes be necessary to balance either the input or outputs of the SDD~000, in order to prevent ground loops or to provide compatibility with pro studio or PA equipment. Since all outputs of the SDD-3000 can drive 600 ohms directly, the use of one or more 'direct' boxes is the simplest solution. - Page 14 B) Selecting a Program The SDD-3000 stores nine effects programs (#1-9) and has a manual mode (#0). Every time the PROGRAM button is depressed, the next higher program will be selected. In other words, if the Program display indicates program #2 is selected, pressing PROGRAM wiII select program #3.
- Page 15 Slapback echo produces a very tight, defined sound, especially useful for filling out a rhythm part. Normally, Slapback requires a delay in the range of 50 - 150 milliseconds, but the precise delay time control! of the SDD-3000 allows the echo to be set up so that it IS exactly in step with the beat, but occurring 1/8 or 1/16 note after each note is played.
- Page 16 Natural Echoes The SDD-3000 normally produces crisp, clean echoes that are very desirable in most situations. Sometimes, however, it is preferable to have echoes where the highs die off more quickly than the lows, as they do in a large room. Other times, 'pipe' echoes with no bass or extreme highs may be needed. All of these effects, and more, can be created through proper use of the HIGH &...
- Page 17 WHAT IS A DIGITAL DELAY A digital delay is basically a device that uses digital technology to store an audio signal for a variable length of time, play it back and combine it in various ways with the original signal. It's sort of like a tape recorder, and in fact many of the most popular effects such as flanging, doubling and echo were originally done using tape recorders.
- Page 18 A basic block diagram of a delay system is shown below (A complete block diagram of the SDD-3000 is included later in this manual). It includes four important parts: 1) the delay line, 2) a way to vary or modulate the delay time, 3) a balance control which mixes the delayed and direct (unprocessed) sounds, and 4) a way to add feedback or regeneration around the delay line.
- Page 19 Let's take these parts one at a time. Delay Line The delay line was basically described above. Again, it's like a movie camera & projector. working with the same piece of film with its ends attached to form a loop. Sound samples are captured and read in by the 'camera' (analog-digital converter), stored for a certain length of time and then read out by the 'projector' (digital-analog converter).

Adding FEEDBACK with short delays normally emphasizes higher frequencies more than lower ones, and this results in sounds that seem harder, more metallic, brittle and/or spacey. However, the Korg Digital Delay provides a pair of switcheable HIGH and LOW filters which can be used to tailor the response of the Feedback. They can be used to... -
Page 21: Setting Chart
SETTING CHART Short delay Used to obtain a normal delay effect. Adjust the feedback and delay time according to the application. Shorten the delay time to achieve a slapback effect (50 milliseconds (approximately)). Long delay Used to obtain a long sound delay of 400 milliseconds. Longer echo effects can be obtained by increasing the delay times. - Page 22 Chorus Used to obtain a normal chorus effect. Adjust the modulation intensity and Frequency according to the application. Flanging Used to obtain a flanging effect. If the feedback level is increased too much, oscillations will occur. Envelope flanger Flanging sound is achieved that is swept by the dynamics (volume level) of the input signal. Especìally effective with percussive sounds (cymbal, drums, etc.).
- Page 23 Bending echo One of the trill delay effects. As the delay time is 350 milliseconds a trill effect with an echo effect can be obtained. Parachute Effective when the input sound dynamic (volume level) change is large. The effect is a pitch bend with the pitch decreasing each time the echo is repeated.
