3. Tuning
The PXR4 has a built-in tuner function.
This lets you tune an instrument connected to the [GUI-
TAR IN] jack or [LINE IN] jack, or by using the internal
mic.
Tuning your guitar
1 Connect your guitar to the [GUITAR INPUT] con-
nector.
Set the [INPUT SELECT] switch to GUITAR.
If you want to tune using the internal mic, set this [INPUT
SELECT] switch to MIC. If you want to tune an instrument
connected to LINE, set this switch to LINE. However in the
case of an instrument connected to LINE, only the L channel
can be tuned.
2 Enter Tuner mode.
While stopped, press the [EFFECT/TUNER] key to
enter Tuning mode.
If EFFECT ASSIGN has been assigned, press the
[EFFECT/TUNER] key once again to enter Tuner
mode.
3 Tune your instrument.
Make sure that your guitar is connected to the [GUI-
TAR INPUT] jack, and play a string on your guitar.
The character display area of the screen will function
as a tuning meter, and will display the note name.
Tune the string while watching the amount of tuning
difference (displayed in units of cents) and the meter
in the display.
The reference pitch frequency is A=440 Hz.
When the tuning is correct
If you do not want the sound to be heard while tuning, set
the [MASTER] fader to 0.
4 Exit Tuner mode.
Press the [EXIT] key to exit Tuner mode.
