Owner's Manual

C 2003 KORG INC.
Printed in China
Introduction
Thank you for purchasing Ampworks — Korg's portable modeling signal processor. To
ensure trouble-free enjoyment, please read this manual carefully and use the product as
described. When you have finished reading the manual, keep it for future reference.
Main features
Ampworks uses Korg's "
" modeling technology to deliver powerful amp, cabinet
and effect modeling sounds. Ampworks is the ideal choice for a wide range of
applications including direct-line recording, live performance and practicing through
headphones.
You can combine eleven types of amps with eleven types of cabinets to simulate
numerous varieties of setups, and also use nine high-performance effects to add
finishing touches to your sound. All this power is easy to control; just use the Amp
Type, Cabinet, and Effect selectors plus the amp and effect knobs to dial-in the sound
you want.
You can select from eleven preset programs that are optimized for each amp type, two
user programs, or use the manual mode.

3. Use the control knobs (6) to adjust the gain, tone, and volume of the modeled amp.
Turn the GAIN knob to adjust the input level from clean to distortion (from left to right).
Turn the TREBLE, MIDDLE, and BASS knobs to adjust the tone.
Turn the VOLUME knob to adjust the volume.
4. Use the EFFECT selector (7) to select the desired modeled effect and use the
EFF.DEPTH knob (8) to adjust the effect level.
For some of the following effects, you can adjust the modulation speed, delay time, or
reverb time. The parameter will be set to a value corresponding to the interval
(maximum 4 seconds) at which you press the TAP button (9) twice.
Effect:
Parameter
Range of parameter value
*Proportion to TAP interval
COMP, WAH:
- - -
- - -
CHORUS, PHASER, ROTARY: Modulation speed
80.0 [ms]...4.0 [s]
FLANGE:
Modulation speed
160.0 [ms]...8.0 [s]
TREM:
Modulation speed
65.0 [ms]...2.0 [s]
DELAY, CHO+DL:
Delay time
80.0 [ms]...1.0 [s]
REVERB, CHO+RV:
Reverb time
approx.0.5 [s]...8.0 [s]
*Proportion to TAP interval means that for example if FLANGE is selected, pressing
the TAP button at a 4-second interval will set the parameter value to twice that length,
or a modulation rate of eight seconds per cycle.
In addition to these settings, you can also adjust the depth of noise reduction by
holding down the TAP button (9) and turning the EFF.DEPTH knob (8).
5. If a user or preset program is selected, and you want to restore the setting of a
specific selector or knob to the setting stored in the program, turn that selector or
knob until the LED of the selected program (PRESET, PROG/MANU) goes dark. The
LED will go dark for an instant, and then light again immediately.
If you select a different program or turn off the power without saving an edited
program, your changes will be lost.
Saving a program
You can store two of your favorite settings in PROG1 and PROG2.
1. Press the WRITE button (10). (The PROG/MANU button will blink.)
2. Press the PROG/MANU button (3) to select where you wish to save your program.
Each time you press the button, the selection will alternate between PROG1 (LED
blinking green) and PROG2 (LED blinking red).
3. Press the WRITE button once again to save your settings. If you decide not to save
your settings, press the CANCEL button (2).
Data that had previously been in the writing-destination will be overwritten and
erased.
The bypass on/off setting is not remembered.
To restore the factory settings
You can restore PROG1 and PROG2 to the factory settings as follows.
Hold down the WRITE button (10) and turn on the power.

Using the optional foot switch
If the optional foot switch (PS-1 or PS-100) is connected to the FOOT SW jack (16), you
can perform an operation at power-on to specify whether the foot switch will change
programs or switch bypass on/off.
If you want to use the footswitch to change programs:
just turn on the power.
Pressing the foot switch will cycle in the order of PROG1

What is
?
(Resonant structure and Electronic circuit Modeling System) is KORG's propri-
etary sound modeling technology which precisely reproduces the complex character
and nature of both acoustic and electric instruments as well as electronic circuits in
real world environments.
emulates a wide variety of sound generation charac-
teristics including instrument bodies, speakers & cabinets, acoustic fields, micro-
phones, vacuum tubes, transistors, etc.
Turning the power on/off
When using batteries:
8. Effect depth knob
1. Slide the battery cover (11) located on the underside of the case toward the UNLOCK
position, and remove it. Insert two AA alkaline batteries (included), being sure to
observe the correct polarity. Close the cover and slide it to the LOCK position to
fasten it in place.
2. When using batteries, the power will turn on when a
mono cable is plugged into the INPUT jack (13). The
POWER LED (1) will light while the power is on.
The power will turn off when you remove the cable
from the INPUT jack.
Be sure to remove the cable from the INPUT jack when you are not using Ampworks
to preserve battery life.
If you connect a stereo cable, the power will not be turned on.
When the batteries run down, the POWER LED will blink. Replace the batteries as
soon as possible. Batteries that have become unusable should be removed from the
unit immediately. If dead batteries are left in the unit, they may leak or cause other
malfunctions. You should also remove the batteries if you will not be using Ampworks
for an extended period.
When using the AC adaptor:
9. TAP button
1. Connect the separately sold AC adaptor to the DC 4.5V jack (12), and plug the AC
adaptor into an AC outlet. The POWER LED (1) will light, and the power will turn on.
7. EFFECT selector
Use only the specified external AC adaptor. (DC 4.5V
Be sure to disconnect the AC adaptor from the AC outlet when you are not using
Ampworks.
Connections
1. Turn off the power of the equipment you want to connect, and lower each volume control.
2. Connect your guitar to the INPUT jack (13).
3. Set the LINE/AMP select switch (14) to the appropriate position for the output destination.
If you connect the output to a mixer, recorder, or headphones, use the "LINE" setting.
If you connect the output to a guitar amp, use the "AMP" position. When AMP is
selected, the cabinet response will automatically be adjusted internally to optimize the
sound produced through a guitar amp.
4. Connect the OUTPUT jack (15) to your mixer or guitar amp.
The OUTPUT jack is stereo (TRS), so if you use a mono cable to connect it to your
12. DC4.5V
guitar amp etc., only the sound of the L (left) channel will be heard.
If you are listening through headphones, connect them to this jack.
11. Battery cover
If you are running into two channels of a mixer or using two amplifiers in stereo, use a
