ATTENTION!
All DIGISYNTHETIC PRO products are carefully packed and designed to protect the units from rough handling
before shipping out from the factory. Examine your good upon receiving, to ensure no damage during transportation.
Any damage claim should be inform & notify to relative dealer within 14 days of good received. The dealer
will not except failing of such. The consignee must make all shipping claims.
The DS100 fits into a standard 19" rack unit of space (1 3/4"). Allow at least an additional 4" depth for the
connectors on the back panel. Be sure that there is enough air space around the unit for cooling and ventilation.
DO NOT place the DS100 on high temperature devices like power amplifiers etc. to avoid overheating.
Using a main cable and a standard IEC receptacle makes the main connection of the DS100. It meets all of the
international safety certification requirements.
Please make sure that all units have a proper ground connection. For your own safety, do not remove the ground
connection within the unit or at the supply, or fail to make this connection at all.
Before switching voltage for local supply requirement, correct fuse type and rate must be installed. Refer to
6.for specifications.
This machine is only intended for qualified personnel to operate & install. Do not attempt to repair and service
yourself but referred to qualified technical service personnel. The user must have sufficient electrical contact
to earth. Electrostatic charges might affect the operation of the DS100.

3. Operation and Editing
This section will provide you with ll of the information necessary to get the most out of your DS100.
3.1 Program Mode
Page 5

When the DS100 is in program mode, you can move from one program to the next by either using the <Program
/Data> wheel, the optional Digitech FS-300 footswitch or incoming MIDI program change commands from
another device such as a sequencer or keyboard.
When the DS100 is in edit mode and you wish to abort and return to program mode, simply press the <Program>
button.
3.2 Storing Changes
When a program has been modified, the program number will blink in the number display when the unit is in
program mode. To store changes, press the button once. The display alternates between and the<Store>
user program location to be stored to. This simply means that DS100 is now giving you the option to store this
modified version of the program as a user program at any number from 1 to 99. At this point, you may use the
<Program/Data> wheel to change the storing position to another program number. When the target preset
location (shown in the display) is correct, press the button once again. The display will momentarily<Store>
read:-- indicating that the modified program is being stored.
3.3 Selecting Effect Configurations
The DS100 provides you with five different effect configurations that allow you ultimate flexibility and
versatility in effect routing.
Effect Module Size
Effect Configuration 1 uses one effect module because both processing engines are combined for maximum
processing power. This larger module allows you to have longer delay times and more dense sounding reverbs.
Effect configurations 2-5 use size effect modules which allow you to use two effects per program.Half
To select any one of these five different configurations, simply perform the following procedure:
Press the button and the display will briefly read: indicating that you are in the configuration<Config>
select mode and now the display will appear something like this:
Now turn the wheel until the desired configuration appears ( - ) in the display.<Program/Data>
To exit the Effect configuration menu, simply press the button where the display will flash the<Program>
program number until the program change is stored or until you change to the next program.
3.4 Adjusting the Dry Path Global Mix
This editing procedure will allow you to globally turn a Dry signal path Off for use with a mixing consoles'
effects sends or On for use with single instrument input signals(such as guitar, saxophone and others). The
procedure is as follow:

To edit the Dry signal within the effect configuration of the DS100(turning it On or Off), press the <Mix/MIDI>
button once and the display will briefly read: indicating the dry path mix and then , indicating that the
Dry signal is on. If you wish to turn the dry path off, simply turn the wheel counter clockwise<Program/Data>
and the display will now read:
This now indicates that the Dry signal has been turned Off creating a 100% Wet signal globally in the DS100.
To exit this mode, press the button.<Program>
Note: The Dry path will automatically be turned off when either a Tremolo, Panner, Vocoder, Compressor,
Rotary Speaker or Reverse Reverb effect is used in a program, since the dry signal is already included
in these effects.
3.5 Selecting the MIDI Channel and MIDI CC Information
To select the MIDI channel in which the DS100 receives program change information, from Program mode,
press the button twice and the display will briefly read: (this indicates MIDI channel mode),<Mix/MIDI>
followed by:
Now turn the wheel to select the desired MIDI channel. The options for the MIDI channel<Program/Data>
selection ranges from: - , and (Off).
MIDI program change numbers will be as follows:
1-99 = Programs
100 = Effects Bypass
101 = Exit Effects Bypass
102 = Effect Bypass Toggle
103 = Selects User Program Bank
104 = Selects Factory Program Bank
To exit the MIDI channel menu, press the button.<Program>
3.6 MIDI CC Information
The DS100 will also receive MIDI CC information for parameter control of the following parameter:
- is turned On or Off by MIDI CC number - CC 7.Dry Level
3.7 EQ and Noise Gate Adjustments
This editing function allows you to make key EQ and Noise gate modifications to custom tailor your sound for
each program. The procedure for both is as follows:

Now press the button and will appear prompting you to adjust the Noise gate Threshold
by turning the wheel. The range for the Noise gate Threshold is from Off, 99 to 0.
To adjust the Noise Gate Release , press the and the display will read: , prompting you
to use the wheel to adjust the Noise Gate Release parameter. Release range is from 1 to 10.
Once all Noise gate modifications have been made, remember to store the changes and press the
button to return to program mode.
Adjusting the EQ
<EQ/Gate>
<Parameter 1-4>
