CA15 digital piano to be enjoyed almost immediately after being connected, while the Internal Songs section (page 17) includes
information regarding the built-in demonstration songs, Piano Music pieces, and Lesson function.
The Recorder section (page 21) provides instructions on how to record and play back pieces stored in the instrument’s internal
memory, and the Settings section (page 23) details the settings that can be used to adjust a number of sound and keyboard
characteristics, as well as basic MIDI functionality.
Finally, the Appendix section (page 38) includes listings for all demo, Piano Music, and Lesson function songs, a troubleshooting

CA15 Feature Highlights
RM3 Grand II wooden-key action with Ivory Touch key surfaces and ‘Let-O ’ mechanism
The CA15 digital piano utilises Kawai’s latest RM3 Grand II wooden-key action, incorporating various grand piano action
characteristics, such as contrasting hammer weights - appropriately graded for each playing range - bass key counterbalancing, and correctly located pivot points for both black and white keys. The unique ‘seesaw’ movement provides
a consistent, evenly balanced action, while nely textured Ivory Touch key surfaces not only enhance the enjoyment of
playing, but also help to absorb moisture, thus preventing ngers from slipping.
The RM3 Grand II keyboard action even reproduces the subtle let-o sensation felt when playing the keys of a grand
piano very softly, satisfying the expectations of even the most discerning pianists.
Progressive Harmonic Imaging (PHI) with 88-key piano sampling
The CA15 digital piano captures the beautiful sound of Kawai’s highly acclaimed hand-built concert grand piano, with
all 88 keys of this exceptional instrument meticulously recorded, analysed and faithfully reproduced using proprietary
Progressive Harmonic Imaging™ technology. This unique process accurately recreates the broad dynamic range of the
original grand piano, a ording pianists an extraordinary level of expressiveness ranging from the softest pianissimo to
the strongest, boldest fortissimo.
Additional modelling techniques and e ects, such as reverb and damper resonance are also applied, delivering a rich
selection of vibrant piano tones with breathtaking realism and authenticity.
Internal Song recorder, Built-in Lesson Function
The CA15 digital piano features a three song recorder, allowing performances to be recorded to internal memory and
played back at the touch of a button. In addition, the convenient lesson feature allows aspiring pianists to learn the
piano using a built-in collection of etudes from Czerny and Burgmüller, or songs from the popular Alfred course books.
The left and right hand parts for each piece can be practiced separately, while adjusting the tempo allows more di cult
passages to be perfected.

Doing so may cause electric shock.
Entry of water, needles or hair pins may result
in breakdown or short-circuit.
The product shall not be exposed to dripping or
splashing. No objects lled with liquids, such as

As with a grand piano, the CA15 digital piano features
three pedals: sustain, sostenuto, and soft.
Soft pedal

Sustain pedal
Sustain pedal
Sustain pedal (right pedal)
Depressing this pedal sustains the sound after one’s hands
have been lifted from the keyboard - greatly enriching the
piano sound, while also assisting smooth ‘legato’ passages.
The sustain pedal is capable of responding to half pedaling.
Soft pedal (left pedal)
Depressing this pedal softens the sound, reducing its volume.
Pedal support bolt
If the pedal support bolt does not make contact with the oor,
the pedal board may become damaged. Ensure that this bolt
is fully extended and supports the pedals rmly.
When moving the instrument, always adjust or
remove the pedal support bolt, then readjust
when the instrument is in its new position.
Sostenuto pedal (centre pedal)
Depressing this pedal after playing the keyboard and before
releasing the keys, sustains the sound of only those notes that
have been played. Any keys that are subsequently played after
the sostenuto pedal is depressed will not be sustained.
Playing the Piano
Caring for the pedals
If the surface of the pedals becomes dirty, clean the pedals using a dry dish-washing sponge.
Do not attempt to clean the pedals using rust-removing solvents, abrasives or les.
Grand Feel pedal system
The CA15 digital piano features the Grand Feel pedal system, which replicates the sustain, soft, and sostenuto pedal weighting of
Kawai’s EX Concert Grand piano.
