Parts of the Pitchblack X mini
Connections
Turn o the power of all devices before you make any connections to avoid
damaging your equipment.
e INPUT and BYPASS jacks are mono. Stereo (TRS) cables will not work.
DC 9V IN jack
Connect a separately sold AC adapter (9 V, ) here. Using an AC adapter
other than what Korg recommends may cause a malfunction or damage.
INPUT jack
Connect a cable from your instrument to the INPUT jack of the tuner. e power
turns on when you connect a cable to the INPUT jack, and the reference pitch
setting blinks in the note name display for several seconds. Connecting a cable to
the INPUT jack will turn the power on, but the tuner will not be in tuner mode.
Press the TUNER ON/OFF switch to engage tuner mode.
BYPASS jack
Connect a cable from the BYPASS jack to your other eect pedals or amp. When
the tuner is switched on, the signal from the INPUT jack will be muted for silent
tuning.
When the tuner is o, it will act as an ultra-buer bypass. e ultra-buer circuit
features zero signal degradation, preventing the sound from thinning out.

Tuning procedure
1. Press the TUNER ON/OFF switch to activate the tuner.
e center of the LED meter will light.
e signal from the INPUT jack will not be output from the BYPASS jack.
Tip: e TUNER ON/OFF switch only functions if an instrument is connected
to the INPUT jack.
2. If necessary, set the reference pitch and the display mode. (page 5
“Reference pitch settings”, page 6 “Display mode settings”)
3. Play a single note on your instrument and tune it so that the desired note
appears in the note name display.
e note name closest to the entered note appears in the note name display.
4. Tune your instrument using the tuning LED meter.
e method for indicating whether your instrument is in tune, sharp or at
depends on which display mode you choose (page 6 “Display mode
settings”).

Tip: e reference pitch, display mode and bright mode settings will be
preserved even if you remove the AC adapter.
Tip: To reset the settings to the factory defaults (reference pitch = 440 Hz,
display mode = regular, bright mode = brighter), hold down the CALIB
button and press the TUNER ON/OFF switch when you turn on the
tuner.

e current setting will blink for several seconds in the note name display.
2. While the setting is shown, press the CALIB button to set the reference pitch.
Each time you press the CALIB button you will cycle through the following
settings.
0: 440Hz
1: 441Hz
2: 442Hz
3: 443Hz
4: 444Hz
5: 445Hz
6: 436Hz

Each time you press the DISPLAY/BRIGHT button you will cycle through the
following settings.
With all display modes, the tuning guide LEDs indicate whether the pitch is
high or low. When the tuning is correct, both

and

light up. If the pitch
is at, the

lights up; and if the pitch is sharp, the

lights up.
1: Regular
Tune your instrument until the LED at the center of the LED meter lights up
brightly.
e right-hand LEDs in the LED meter light up if the pitch is high, and the
le-hand LEDs light up if the pitch is low.
2: Strobe
Tune your instrument until the LEDs stop running. Since the strobe meter has
a higher precision, it allows you to tune with greater accuracy.
e LEDs light up, running from le to right if the pitch is high and from right
to le if the pitch is low.
3: Half-strobe
Tune your instrument until the LEDs stop running and only the center LED is lit.
e right-hand LEDs will strobe if the pitch is high, and the le-hand LEDs will
strobe if the pitch is low.
