Installing the battery
Slide o the back cover of the GA-2 to open the baery compartment.
Making sure to observe the correct polarity, insert the baeries, and
then slide the back cover to close the baery compartment.
If the unit malfunctions and you are unable to correct the prob-
lem by turning the power o and on several times, remove the
baeries and then reinstall them.
When the baeries run low, the display will blink slowly. Replace
the baeries as soon as possible.
Tuning procedure
■ Meter mode
In this mode, the VU style meter shown in the display is used to
tune your instrument.
1. If an instrument equipped with a pickup (such as an electric
guitar) or the optional Korg CM-200 contact microphone is used,
connect the instrument or mic cord (plug) to the INPUT jack of
the GA-2.
If you wish to tune your instrument using the built-in mic, do
not connect a plug to the INPUT jack. In steps 4 and 5, place your
instrument as close as possible to the built-in mic.
If a plug is connected to the INPUT jack, the built-in mic cannot
be used. The INPUT jack is for mono use only. Stereo plugs
cannot be used.
2. Press the power buon to turn on the GA-2.
When the power is on for 20 minutes without use, the tuner will
automatically turn o to conserve baery life.
3. Press the GUITAR/BASS buon to select the instrument that you
want to tune (*).
Each instrument can be tuned to the notes listed below.
GUITAR : 7B, 6E, 5A, 4D, 3G, 2B, 1E
BASS : LB, 4E, 3A, 2D, 1G, HC (LB: Low B, HC: High C)
4. Play a single note on your instrument, and the name of the nearest
note will appear in the display. Tune your instrument so that the
correct note name is shown in the display.
5. Play a single note on your instrument, and tune it so that the
meter needle points to the middle and the center indicator of the
tuning guide is lit (if using A=440 Hz as the reference pitch). If
your instrument is at, the left indicator will light. If it is sharp,
the right indicator will light.
Each marking in the meter scale corresponds to 2 Hz. For example
if you want to tune each string of your instrument using a refer-
ence pitch of A=436 Hz, adjust the tuning of each string so that
the needle indicates two steps below «440».
While tuning with the built-in mic a quiet environment is
recommended for precise tuning.
■ Sound Out mode
In this mode you can tune while listening to a reference tone.
1. Follow steps 2–3 outlined in “Meter mode.”
2. Press the SOUND buon to enter Sound Out mode.
3. Press the SOUND buon until the note to which you wish to tune
appears in the display. For the notes that can be output, refer to
step 3 of «Meter mode.» When you make a complete cycle, you
will return to Meter mode.
GUITAR will output a pitch that is one octave higher than the
actual pitch of your instrument, and BASS will output a pitch
that is two octaves higher.
4. Listen to the tone sounded by the GA-2, and tune your instrument
accordingly.
● Flat tuning
You can use Meter mode or Sound Out mode to tune to a pitch that
is lowered by 1-5 semitones for the specied note.
1. As described in “Meter mode” or “Sound Out mode,” make the
note you wish to aen by 1-5 semitones appear in the display.
2. Press the FLAT buon to select the number of semitones that you
wish to lower the selected note.
The display will indicate - (1-5 semitones). (This seing is
not remembered when you turn the power o.)
3. Listen to the tone sounded by the GA-2, and tune your instrument
accordingly.
