Troubleshooting
If you perceive any malfunction, check the following
suggestions. If the problem persists, contact your nearest
distributor.
Power does not turn on
•Make sure that the AC adapter is properly connected
to the PRK-80 and the AC outlet.
•Make sure that the power light is illuminated.
No sound from the speakers
•Rotate the VOLUME knob on the rear panel to the right
toward MAX.
•The speakers will be muted if the headphones are con-
nected.
Sound is interrupted
•The preset sounds of the PRK-80 have been created
by sampling (recording) sounds of actual musical in-
struments. When you press a key, some sounds play
a single piece of sampled data, while other sounds
play two pieces of sampled data. The PRK-80 uses two
pieces of data for most of its preset sounds. When one
of these two-sample sounds is selected (regardless of
whether the Sustain pedal is being pressed), the maxi-
mum polyphony is 60 notes. However, Piano 2 sounds,
the maximum polyphony is 120 notes. If the maximum
polyphony is exceeded, some of the notes will not be
sounded.
The pitch or tone of the piano sounds wrong in some key
regions
•The PRK-80’s piano sounds replicate the sound of an
actual piano as faithfully as possible. This means that
in some regions of the keyboard, you may feel that
the overtones seem stronger, or that the tone or pitch
seems wrong. This is not a malfunction.
Pedal is not effective
•Make sure that the pedal cable is properly connected.
Connected MIDI device does not respond to MIDI messag-
es
•Make sure that all MIDI cables are properly connected.
•Make sure that the PRK-80 is transmitting MIDI data
on the same MIDI channel as the connected MIDI de-
vice.

Key Functions [ ]* indicates MIDI Note number.
Transpose function (Shifting the key)
In somecases, a song maybe wrienin a dicultkey
(e.g., using many black keys), or you may wish to shift
the key to match another instrument or vocalist. In such
cases, you can transpose (shift the key) to use an easier
ngering, or to use the samefamiliarngeringto play
inadierentkey.ThisiscalledtheTransposefunction.
You can shift the key in a range of eleven semitones.
For example if you transpose upward by one semitone,
playing the notes shown in the score on the left below
will produce the pitch that’s shown in the score on the
right.
• To transpose the key, press and hold down the PIA-
NOPLAYandSOUNDbuons,andthenpressakey
from F#2 to B3 or from C#3 to F3. The name of the key
that you pressed will become the transposed key.
For example, if you wish to use the C3 key to play note
A2 (lower by three semitones), press and hold down the
PIANO PLAY and SOUND buttons, and press the A2
key. If you wish to use the C3 key to play note D#3 (higher
by three semitones), press and hold down the PIANO
PLAYandSOUNDbuons,andpresstheD#3 key.
To reset the Transpose function to “No Transposition
(+/-0),” press and hold down the PIANO PLAY and
SOUNDbuons,andthenpresstheC3key.
Thedefaultseing(whenyouturn ontheunit)is“No
Transposition.”
Pitch Control function (Tuning)
When you’re playing together with other instruments,
you can use this the Pitch Control function to fix any
slight differences in pitch between instruments. You
can adjust the tuning of the PRK-80 in half-step (0.5) Hz
intervalsoverarangeof427.5–452.5Hz(Her)byusing
the E5 and F5 keys.
• Press and hold down the PIANO PLAY and SOUND
buons, then press the E5 key to lowerthe pitchin-
0.5H steps each time your press it, or press the F5 key
repeatedly to raise the pitch in 0.5Hz steps each time
you press it.
• To reset the pitch to 440Hz, press and hold down the
PIANOPLAYandSOUNDbuons,andpresstheE5
and F5 keys simultaneously.
The default setting (when you turn on the unit) is
A4=440H T
