Thank you for purchasing the  
Korg OT–120 Orchestral  
Tuner. Before you use the OT–  
120, please read this owner’s  
manual carefully and use the  
unit as directed. After you  
have read the manual, keep it  
for future reference.  
The batteries are also used to maintain the contents of memory when the  
power is off in order to preserve the reference pitch, TRANS/TEMPERA-  
MENT setting, and the note name selected in Manual Meter mode or Sound  
mode (Memory function).  
Manual meter mode  
Front and side panels  
In this mode you can tune to a note name that you specify.  
1. Make the settings described in steps 1–4 of “Preparations for tuning.”  
2. Set the [MODE] dial to MANUAL.  
AUTO : Auto Meter mode (SLOW, MEDIUM, FAST)  
MANUAL : Manual Meter mode  
SOUND : Sound, Sound Back mode  
The various settings of the Memory function will be reset when you remove  
the batteries or when the batteries run down. (If the AC adapter is plugged in  
and connected to the OT–120, these settings will not be reset.)  
3. Press the NOTE [] or [®] switch to select the note name (C–B) that you  
wish to tune.  
Each time you press the switch, the note name will change in semitone  
steps. If you press and hold the switch, the note name will change continu-  
ously.

4. Play a single note on your instrument, and tune so that the VU style meter  
moves to the 0 position (center) and the tuning guide indicators are both  
lit.  
The meter will operate when the difference between the specified note and  
the input pitch is in the range of -500 cents – +500 cents.

Please connect the designated AC adapter to an AC outlet of the correct voltage. Do not  
connect it to an AC outlet of voltage other than that for which your unit is intended.

Adjusting the zero point of the VU style meter  
1. Make the settings described in steps 1–4 of “Preparations for tuning.”  
If the OT–120 is jarred while being transported etc., or due to normal aging  
after extended use, the VU style meter may drift away from the 0 position  
(center). Please re-adjust the VU style meter to the 0 position so that tuning  
will be accurate.  
2. Set the [MODE] dial to AUTO-SLOW, AUTO-MEDIUM, or AUTO-FAST.  
AUTO-SLOW: The VU style meter will respond slowly to the input sound.  
AUTO-FAST: The VU style meter will respond rapidly to the input sound.  
AUTO-MEDIUM: The response will be between that of AUTO-SLOW and  
AUTO-FAST.  
Interference with other electrical devices  
Radios and televisions placed nearby may experience reception interference. Operate this unit  
at a suitable distance from radios and televisions.  
Tuning procedure  
The OT–120 provides four modes: Manual Meter, Auto Meter (SLOW/  
MEDIUM/FAST), Sound, and Sound Back.  
Handling  
To avoid breakage, do not apply excessive force to the switches or controls.  
1. While holding down the NOTE [] switch, turn the power switch ON  
and verify that the VU style meter points to the 0 position.  
3. Play a single note on your instrument.  
The LCD display will indicate the closest note name and the octave for the  
pitch that you played.  
Tune your instrument approximately so that the correct note name is  
displayed.  
Care  
Preparations for tuning  
1. If you are using an instrument with a pickup or contact mic, connect the  
INPUT jack of the OT–120 to the cable (plug) from your instrument or  
mic.  
If the OUTPUT jack of the OT–120 is connected to an amp, the sound that is  
input to the INPUT jack will be output without change. Since this may cause  
noise during your performance, set the power switch of the OT–120 to  
STANDBY .  
If you are using the internal mic of the OT–120, tune without connecting a  
plug to the INPUT jack and OUTPUT jack. If a plug is connected to the  
INPUT jack or OUTPUT jack, the internal mic cannot be used.  
If the exterior becomes dirty, wipe it with a clean, dry cloth. Do not use liquid cleaners such as  
benzene or thinner, or cleaning compounds or flammable polishes.  
2. If it does not point to 0, open the battery case lid as shown in the diagram  
for “Replacing the batteries/Memory function,” and use a small Phillips  
screwdriver (jeweler's screwdriver) to rotate the adjustment screw until  
the VU style meter points to 0.  
Keep this manual  
After reading this manual, please keep it for later reference.  
Keeping foreign matter out of your equipment  
Never set any container with liquid in it near this equipment. If liquid gets into the  
equipment, it could cause a breakdown, fire, or electrical shock.  
Be careful not to let metal objects get into the equipment. If something does slip into the  
equipment, unplug the AC adapter from the wall outlet. Then contact your nearest Korg  
dealer or the store where the equipment was purchased.  
4. Tune your instrument so that the VU style meter moves to the 0 position  
(center) and the tuning guide indicators are both lit.  
The meter will indicate the difference between the specified note and the  
input pitch in the range of -50 cents – +50 cents.  
3. After completing the adjustment (or if the VU style meter already points  
to 0), press any switch to return to normal operation, and close the lid.  
Specifications  
If you use the internal mic of the OT–120 to tune, place your instrument as  
close as possible to the internal mic so that extraneous sounds are not picked  
up by the mic.

THE FCC REGULATION WARNING (for U.S.A.)  
In some cases, such as when the sound contains numerous overtones, the OT–  
120 may have difficulty detecting the pitch. If this occurs, change the volume  
or octave, and try again.  
: A0 (27.50 Hz)–C8 (4186 Hz)  
This equipment has been tested and found to comply with the limits for a Class B digital  
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide  
reasonable protection against harmful interference in a residential installation. This  
equipment generates, uses, and can radiate radio frequency energy and, if not installed  
and used in accordance with the instructions, may cause harmful interference to radio  
communications. However, there is no guarantee that interference will not occur in a  
particular installation. If this equipment does cause harmful interference to radio or  
television reception, which can be determined by turning the equipment off and on, the  
user is encouraged to try to correct the interference by one or more of the following  
measures:  
• Reorient or relocate the receiving antenna.  
• Increase the separation between the equipment and receiver.  
• Connect the equipment into an outlet on a circuit different from that to which the  
receiver is connected.  
• Consult the dealer or an experienced radio/TV technician for help.
