Connecting the DG-1000
To set up a guitar amp system, connect the DG-1000 to a power amp
and speaker.
As you know, power amps and speakers all have their own special char-
acteristics. So the sound's character will change according to the type
of devices used. The combined result of each device's character, room
temperature, room humidity, and a variety of other factors, determines
the guitar's sound. The purpose of the DG-1000 is to create sound by
faithfully reproducing the dynamic range and tone nuance of the guitar
as well as preserving the characteristics of the power amp, speakers,
etc. The DG-1000 will surely provide you with the means to create your
own personal sound.
Connecting Procedure
Make sure that the power is switched OFF on the DG-
1000 and the power amp (guitar amp) before making any
connections.
1. Connect the OUTPUT jack on the rear panel of the DG-1000 to
the INPUT jack on the power amp using a cable.
* Choose a cable that matches the required jack standard. The DG-
1000's OUTPUT jack is monaural.
2. Connect the power amp's speaker output (SPEAKER, etc.) to a
speaker.
* Use a speaker that matches the power characteristics of the amp
(power capacity, system impedance).

How to use the DG-1000
Once the amp and speaker has been properly set up, try getting some
sound out of the system.
First, acquire sound
1. With the DG-1000 and power amp (guitar amp) power switched
OFF, connect the guitar to the INPUT jack on the front panel.
2. With the OUTPUT knob set to "0", switch the power ON.
3. A short time after the power has been switched ON, the DG-
1000's internal relay will produce a small "Click" sound. Once
the sound is heard, set the power amp's (guitar amp's) volume
to "0" and switch the power ON on the power amp (guitar amp).
4. At first, set the DG-1000's TRIM and OUTPUT levels to "5" and
strum the guitar. Then adjust the power amp's volume level.
5. Once you have sound, set the TRIM and OUTPUT levels as de-
scribed in the following procedures.
Set the TRIM level
The TRIM level is used to set the output level of the guitar to an optimum
level for the DG-1000's INPUT jack. Depending on the TRIM level subtle
picking nuances and the attack of a strong strum can be realized.
An improperly adjusted trim level will result in noise, feedback and a cut
up sound.
* Output levels vary according to the type of guitar used. If a different
guitar is used, adjust the trim level to match the guitar.
* Even to create distortion, make sure that the TRIM level is properly
adjusted, and use the GAIN control to create distortion.
1. Set the guitar's volume to its maximum level and strum it pow-
erfully. Begin to adjust the TRIM level.
An optimum level is achieved when the Green LED is lit.
2. Continue adjusting the TRIM knob until the Red LED lights. Set
the TRIM level to 10 if the Red LED does not light. If the Red
LED lights, lower the TRIM level until the Green LED lights.
Set the OUTPUT level
Use the OUTPUT knob to set the DG-1000's required OUTPUT level.
Sound Setting
Choose one of the DG-1000's 8 preset amp types, then use the
GAIN+MASTER, and Tone Controls to shape the sound.
1. With one of the AMP SELECT buttons choose an amp type. The
LED will light on the selected amp type button.
2. Use the GAIN, MASTER, and the 5 Tone Controls to shape the
sound.
* When an AMP SELECT button is pressed, all knobs (Except TRIM
and GAIN) will return to their preset positions (GAIN & MASTER =
7, Tone Controls all = 5). To save edited settings, refer to "Store Set-
tings" on the next page.
