How to use the DG100-212

To protect the speaker from possible damage, always set the OUTPUT knob to “0”
before switching the power ON/OFF.

HINT

OUTPUT knob and MASTER knob

Turning either knob will change the volume. The MASTER knob

controls the preamp’s master volume. This setting is stored in

memory. The OUTPUT knob controls the power amp’s volume.

This setting is not stored in memory. Volume levels for individual

memory settings should be set with the MASTER knob. The

speaker’s output level should be controlled with the OUTPUT knob.

When an AMP SELECT button is pressed, all knobs (except TRIM,
OUTPUT and REVERB) will return to their preset positions. (GAIN
and MASTER = 7, all tone controls = 5. To save edited settings, refer to
the “Store Settings” section on page 9.)

■

First, achieve sound output

With the DG100-212’s power switched OFF, connect your gui-

tar to the INPUT jack on the front panel. To start with, try using

the LOW jack.

With the OUTPUT knob set to “0”, switch the power ON.

As a starting point, set the TRIM level to “5” and strum the gui-

tar. Then, gradually raise the OUTPUT level.

Once you have sound output, proceed to set the TRIM level as

described in the following section.

■

Adjust the TRIM level

The TRIM level allows you to set the output level of the guitar to an

optimum level that matches the DG100-212’s INPUT jack. With a well

adjusted TRIM level, subtle picking nuances and the attack of a strong

strum can be clearly heard. An improperly adjusted trim level will result

in noise, feedback, and/or a cut up sound.

The output level between guitars does vary. Whenever you switch guitars, it
will be necessary to readjust the trim level to match the guitar.

HIGH and LOW input levels are different. Even if the same guitar is used,
make sure the TRIM level is readjusted whenever a different input jack is
used.

Even when creating distortion, make sure that the TRIM level is properly
adjusted, and use the GAIN control to produce distortion.

Set the guitar’s volume to its maximum level and powerfully

strum the guitar. Begin to adjust the TRIM level.

An optimum level is achieved when the Green LED is lit.

Continue rotating the TRIM knob to the right, so long as the

Red LED does not light. Set the TRIM level to 10 if the Red LED

does not light.

* If the Red LED still does not light, lower the TRIM level, connect the

guitar to the HIGH input jack and repeat the previous procedure.

■

Sound Settings

Choose one of the DG100-212’s eight preset amp types, then use the

GAIN+MASTER, and tone controls to shape the guitar’s sound.

Choose an amp type using one of the AMP SELECT buttons.

The selected amp type button’s LED will light.

Use the GAIN, MASTER, and the five tone controls to shape the

guitar’s sound.

■

Reverb Settings

Three types of digital reverb are available in the DG100-212’s reverb

section. Spring reverb, which realistically simulates the reverb found in

vintage guitar amps, plate reverb, and hall reverb.

Press the REVERB button to select a reverb type. Each time

the REVERB button is pressed, the type will cycle through

SPRING

→

HALL

→

PLATE settings. The lamp for the selected

reverb type will light.

Use the REVERB knob to adjust the amount of reverb.

Reverb settings (type and REVERB knob settings) will remain in affect,
even if the AMP SELECT button is pressed to change the amp type. When a
different memory number is recalled, the reverb settings for that memory
number will then be in affect.

■

Tape Echo Settings

The DG100-212’s internal digital tape echo can realistically simulate

the sound of a tape type echo machine.

Press the

button to enter the Tape Echo setting mode,

the “TAPE ECHO” display lamp will light. At this time BASS,

PRESENCE and REVERB knobs will automatically reset to “0”.

* If there are previously set tape echo settings in the selected memory, the

knobs will rotate to the positions set in the memory.

Use the BASS, PRESENCE and REVERB knobs to adjust the

amount of tape echo reverb.

• BASS (TIME: Echo Time)

Sets the amount of time between the sounding of the string and

the echo sound (the amount of time it takes between one echo

and the next). Rotate the knob to the right to increase the amount

of time.

• PRESENCE (FEEDBACK)

Sets the length of time that the echo will repeat. Rotate the knob

to the right to increase the length of time. Rotating the knob too

much can result in uncontrollable feedback, please use caution.

• REVERB (LEVEL: Echo Level)

Sets the echo’s volume level.

When the setting procedure is complete, press the

button and the PLAY lamp will light.

The BASS, PRESENCE and REVERB knobs will revert to the

settings that they were in prior to entering the tape echo set-

ting mode.

When in the Tape Echo Mode, knobs other than the BASS, PRESENCE and
REVERB knobs, as well as the TRIM and OUTPUT knobs will not function.

Tape echo settings will remain in affect, even if you press the AMP SELECT
button to select another amp type. When you recall a different memory num-
ber, the tape echo settings for that memory number will then be in affect.

With the procedures on this page, you can create an
original sound (settings), and along with the reverb
and echo settings they can be stored in the DG100-
212’s internal memory for instant recall at anytime. The
procedure for storing data in memory is explained on
the next page.
