Setting the Calibration
Here’s how to set the calibration (the reference
pitch used for tuning, expressed as the pitch of
the middle A note (A4) on a piano).
You can set the calibration independently
for the INPUT A and INPUT B input jacks.
When you use the INPUT SELECT switch
to change inputs, the setting will also
change automatically.
The calibration settings are stored in
internal memory. Even if you remove the
battery or disconnect the AC adapter, the
pitchblack+ will recall the settings stored
in internal memory the next time you turn
the power on.
1 Press the CALIB button.
The display will indicate the current setting.
When the pitchblack+ is shipped from the
factory this is set at 40: 440 Hz.
2 Use the UP button or DOWN button to
specify the calibration.
40: 440 Hz 41: 441 Hz 42: 442 Hz
43: 443 Hz 44: 444 Hz 45: 445 Hz
36: 436 Hz 37: 437 Hz 38: 438 Hz
39: 439 Hz
If you decide to cancel the change you
made, press the TUNER ON/OFF switch or
press the INPUT SELECT switch to change
between A or B.
3 Press the STORE button.
The INPUT SELECT indicator will blink. If
the A and B settings are identical, the A and B
indicators will blink. If the A and B settings
differ, the indicator selected by the INPUT
SELECT switch will blink.
4 Use the UP button, DOWN button, or
INPUT SELECT switch to select the internal
memory in which you want to store the
setting.
5 Press the STORE button once again.
The calibration setting will be stored in the
internal memory you specified, and the
pitchblack+ will return to tuning mode.
