NU1 Owner’s Manual3
Thank you for choosing the Yamaha Hybrid Piano.
In order to make the most of the performance potential and features of the instrument,
please read the manuals thoroughly,
and keep them in a handy place for later reference.
This instrument, which combines the priceless value of an acoustic piano and versatile digital tech-
nology that provides exceptional flexibility to performers, is a true hybrid piano.
Main Features
Authentic acoustic piano touch with special upright piano action
Featuring a specially designed mechanism in which the keyboard action and the hammer workings realistically reproduce those of an acoustic piano, this instrument provides a realistic touch response that is
extraordinarily similar to an upright piano.
CFX Sampling technology
Sophisticated sampling using the latest technology was used to capture the luxurious sounds of
Yamaha’s flagship CFX, a full-sized concert grand piano. The powerful bass and bright, penetrating
midrange sound of the original CFX are reproduced faithfully, and give a particularly natural and wellbalanced overall piano sound.
Best Condition without Tuning
Unlike acoustic pianos, this instrument does not need to be tuned. It always stays perfectly in tune even
after long-time use.
Flexible Volume Control
This instrument gives you full control over the instrument volume, letting you adjust the level just as
desired. Also, you can play or listen in total privacy through one or two pairs of headphones.
Audio Playing and Recording from a USB Flash Memory
Audio files (.wav) saved to a USB flash memory can be played back on the instrument. Moreover, since
you can record your performance as audio data to a USB flash memory device, it is possible to listen to
your performance on portable music players, with the data transferred by computer.
* This is a quick reference for operation of the functions assigned to the buttons
and keyboard.

you are not using the product for a long time, make sure to unplug the power cord
from the wall AC outlet.
• Though the wooden parts of this instrument have been designed and produced
with care concerning the environment and human health, in some rare instances
customers may sense an unusual odor or develop irritation in the eyes, due to the
coating material and adhesive.
To avoid this, we recommend that you observe the following:
1. Specially ventilate the room for several days after unpacking and installing this
instrument, since it has been packed in airtight conditions in order to maintain
quality during transportation.
2. If the room housing the instrument is small, continue to ventilate it normally,
either daily or periodically.
3. If you have left the instrument in a closed room for a long time under high
temperature, ventilate the room, then lower the temperature if possible, before
using the instrument.

Playing the Keyboard
If you press and hold the
damper pedal here, all the
notes shown will be sustained.
E6
A#5
If you press and hold the sostenuto pedal here, only the notes
held at this timing will be sustained.
Using the Pedals
The instrument has three pedals that produce a range of expressive effects similar to those produced by the pedals on
an acoustic piano.
Damper Pedal (Right)
Pressing this pedal will sustain notes longer. Releasing this pedal immediately stops
(damps) any sustained notes. A “half-pedal” function of this pedal creates partial sustain effects, depending on how far down you press the pedal.
Half-pedal function
This function allows the sustain length to vary depending on how far the pedal is
pressed. The farther you press the pedal, the more the sound sustains. For example, if
you press the damper pedal and all notes you are playing sound a bit murky and loud
with too much sustain, you can release the pedal half way to subdue the sustain (murkiness).
To set the Half Pedal Point:
While holding down [PIANO/VOICE], press one of the A#5–E6 keys. This operation
sets the degree to which pressing the damper pedal applies the half-pedal effect. The
smaller the value, the shallower the half-pedal point. The larger the value, the deeper
the half-pedal point.
This special pedal has been designed to provide enhanced tactile response and, when
pressed, is much closer in feel to the pedal of an actual grand piano. It makes it easier
to physically experience the half-pedal point and more easily apply the half-pedal
effect than other pedals.
Sostenuto Pedal (Center)
Pressing this pedal while holding the notes will sustain the pressed notes (as if the
damper pedal had been pressed), but all subsequently played notes will not be sustained. This makes it possible to sustain a chord, for example, while the other notes are
played “staccato.”
Soft Pedal (Left)
Pressing this pedal will reduce the volume and slightly change the timbre of the notes.
The notes played before this pedal is pressed are not affected.

insert a plug into either jack, shutting off the speakers.
CAUTION
Avoid listening to the instrument at a high volume level
through headphones for a long period of time, to prevent
hearing damage.
I.A. Control (Intelligent Acoustic Control)
This function automatically adjusts and controls the sound quality according to the overall volume of the instrument.
Even when the volume is low, it permits both low sounds and high sounds to be clearly heard. Note that the I.A. Control is effective only from the sound output of the instrument speakers.
To turn on/off the I.A. Control:
While holding down [FUNCTION], press the C0 key repeatedly (as necessary).
Default setting: On
To adjust the I.A. Control Depth:
While holding down [FUNCTION], press one of the keys between A0–D#1.
