Yamaha P45 Owners Manual

							Setting Up
P-45  Owner’s Manual11
To enable the Auto Power Off function: 
While holding down [GRAND PIANO/FUNCTION], 
press the A#-1 key.
When you start playing, use the [MASTER VOL-
UME] slider to adjust the volume of the entire key-
board sound. 
Because of the simple, piano-like design of this instru-
ment, there are a minimum of panel controls, and 
most settings are made using the keys of the keyboard. 
When you turn a function on or off, or change a set-
ting, the instrument produces a sound to confirm the 
change. There are three types of sounds used: an 
ascending sound for on, a descending sound for off, 
and clicks for other settings. For the list of functions 
assigned to the buttons and keys, see “Quick Opera-
tion Guide” on page 22.
Setting the Operation Confirmation Sounds 
On or Off
You can enable or disable the Operation Confirmation 
Sounds as desired.
While holding down [GRAND PIANO/FUNCTION], 
press the C7 key. Every time you press the C7 key, the 
setting is switched on or off.
Default setting:  on
Any pair of stereo headphones with a 1/4” stereo 
phone plug can be plugged in here for convenient 
monitoring. The speakers are automatically shut off 
when a plug is inserted into this jack.
The [SUSTAIN] jack is for connecting the included 
footswitch, which works in the same way as a damper 
pedal on an acoustic piano. Also an optional FC3A 
foot pedal or FC4A or FC5 footswitch can be con-
nected to this jack. The FC3A lets you use the Half 
Pedal function.
Half Pedal function
If you are playing the piano with sustain and want a 
clearer, less muddled sound (especially in the bass 
register), let up on your foot from the pedal to half 
position or higher.

Using Headphones
• To protect your hearing, avoid listening with the head-
phones at a high volume level for long periods of time.
Using a Footswitch
• Do not press the footswitch when turning the power on. Doing this changes the recognized polarity of the footsw itch, resulting in reversed footswitch 
operation.
• Make sure that power is OFF when connecting or disconnecting the foot- switch or pedal.

PIANO 1 Recorded samples from a full concert grand 
piano. Perfect for classical compositions as 
well as any other style that requires acoustic 
piano.
C#0GRAND 
PIANO 2
Bright piano sound. Clear tone helps the 
sound to “cut through” when playing in an

struck metallic “tines.” Soft tone when played 
lightly, and an aggressive tone when played 
hard.

You can specify the Touch Sensitivity (how the sound 
responds to your playing strength).
While holding down [GRAND PIANO/FUNCTION], 
press one of the A2 – C3 keys.
Touch Sensitivity
You can shift the pitch of the entire keyboard up or 
down in semitone in order to facilitate playing in diffi-
cult key signatures, or to easily match the pitch of the 
keyboard to the range of a singer or other instruments. 
For example, if “+5” is selected, playing key C pro-
duces pitch F, letting you play a song of F major as 
though it were in C major.
Setting range: -6 – 0 – +6
To transpose the pitch down:
While holding down [GRAND PIANO/FUNCTION], 
press the F6 key to decrease by 1 semitone. 
To transpose the pitch up:
While holding down [GRAND PIANO/FUNCTION], 
press the G6 key to increase by 1 semitone. 
To restore the original pitch:
While holding down [GRAND PIANO/FUNCTION], 
press the F#6 key. 
Setting the Touch Sensitivity
KeyTouch 
SensitivityDescription
A2 Fixed The volume level does not change at all 
regardless of whether you play the key-
board soft or hard.
A #2Soft The volume level does not change much 
when you play the keyboard soft or hard.
B2 Medium This is the standard piano touch response 
(default setting).
C3 Hard The volume level changes very widely 
from pianissimo to fortissimo to facilitate 
dynamic and dramatic expression. You 
have to hit the keys hard to produce a 
loud sound.
• The Touch Sensitivity settings may have little or no effect with the PIPE ORGAN  and HARPSICHORD Voices, since these in struments are not normally respon-
sive to keyboard dynamics.

ProblemPossible Cause and Solution
The instrument does not turn on. The instrument has not been plugged in properly. Securely insert the female plug into 
the jack on the instrument, and the male plug into a proper AC outlet (page 10).
The instrument is automatically turned off even if 
no operation is done. This is normal. This occurs due to the Auto Power Off function (page 10).
Noise is heard from the speakers or head-
phones. The noise may be due to interference caused by the use of a mobile phone in close 
proximity to the instrument. Turn off the mobile phone, or use it further away from the 
instrument.
Noise can be heard coming from the digital 
piano’s built-in speakers and/or headphones 
when using it with an iPhone/iPad/iPod touch 
app. In order to eliminate the risk of noise from other communication when using the instru-
ment with an iPhone, iPad, or iPod touch, we recommend turning on the device’s Air-
plane Mode.
The overall volume is low, or no sound is heard. The Master Volume is set too low; set it to an appropriate level using the [MASTER 
VOLUME] slider (page 11).
Make sure a pair of headphones or conversion adaptor is not connected to the head-
phones jack (page 11).
The pedal has no effect. The pedal cable/plug may not be properly connected. Make sure to securely insert the 
pedal plug into the [SUSTAIN] jack (page 11).
The footswitch (for sustain) seems to produce 
the opposite effect. For example, pressing the 
footswitch cuts off the sound and releasing it 
sustains the sounds. The polarity of the footswitch is reversed because the footswitch was pressed when the 
power was turned on. Turn off the power and turn it on again to reset the function. Make 
sure to not press the footswitch when turning the power on.
