– KAWAI GX –The new standard of grand piano design is beyond imagination.
Combining state-of-the-art technology with traditional craftsmanship.
Applying knowledge and experience handed down from generation to generation.
Defining the ‘made in Japan’ philosophy of piano building.
Lightness of touch usually experienced by only the very finest concert pianists.
Rich, vivid, expressive tone that inspires one’s creative passion.
A new era of grand piano performance has arrived.

Joyous touch to awaken one’s imagination

The new GX Series grand pianos aim to reproduce
the delicate control of a full concert grand piano,delivering a level of refinement that few pianists havethe opportunity to experience.
In order to achieve this ambitious goal, the lengthof the keyboard has been extended significantly,

In addition, the GX Series’ advanced Millennium III keyboard action
incorporates the latest materials; combining ABS resin with carbon
fibre to further improve one’s playing experience. This ABS-Carbon
compound is both highly rigid and extremely lightweight – characteristics
that have seen the same material successfully employed throughout the
aeronautics industry as a superior alternative to wood. By utilising action

increasing the fulcrum distance for each key. Thisextended key pivot length results in a more consistent
touch weight when playing towards the back of the
keyboard, affording the pianist greater expressive
control, and allowing one’s imagination to soar freely.

parts fashioned from ABS-Carbon, the GX Series’ keyboard action ismore durable and less prone to performance degradation over time, while
also delivering improved responsiveness and control. This evolution in
keyboard touch can be experienced by the pianist with every key stroke,from the first to the very last note played.

Purity of tone that fills the room

In order to produce Kawai’s special tone, a broad range of woods are
meticulously analysed for quality and character, before being selected as thefinest materials for each specific purpose. The soundboard has arguably themost significant influence over a piano’s individual tonal elements. Therefore,woods that conform to the most rigorous gravity and propagation velocity
standards are carefully selected by experienced craftsmen in order to achieve

In order to produce a richer, more immersive sound,
the overall rigidity of the GX instruments’ bodyhas also been improved. The thickness of the upper
beam that attaches to the outer-rim is increased,
allowing the pin blocks to support a tensile strengthload of approximately 20 tons. As the tone of eachrich, deep bass tones, and bright, colourful, sustaining treble tones. In
addition to the soundboard, bridges, and ribs, optimum materials for the
inner-rim are also carefully considered, combining the unique properties ofdifferent hardwoods to create a layered hybrid construction. This produces abroad range of sound, allowing even greater expressive power.

note is improved, the sense of three-dimensionalsound is also enhanced. Moreover, increasing therigidity of the piano’s carbon steel tuning pins
further strengthens the instruments’ tuning stability,
to meet the rigorous demands of the finest pianists.

Quiet yet strong, Loud yet delicate –Unparalleled tonal expression
In order to realise the pianist’s infinite range of expression, the GX Series utilises premium
grand piano hammers. These hammers are constructed from wood that possesses excellent
acoustic properties, with hammer felt prepared from the finest quality long-haired New
Zealand and Australian wool. These felted hammers have a soft, delicate exterior, yet are
tight and rigid on the inside. When playing pianissimo passages, the strings are struck by
the delicate exterior felt of the hammer to produce a soft and gentle tone, while fortissimo

The instrument’s duplex scale system further enhances
the harmonics of middle and upper-range tones,
adding depth and breadth to the overall sound.
And to ensure the ultimate touch at the keyboard
surface – that magical point where the pianist andthe piano become one – all GX instruments adopt

passages utilise the tighter, harder interior felt, thus producing a louder, more powerful sound.
Moreover, all hammers are under-felted in order to further improve their resilience. These
steps allow experienced piano technicians to perform the most subtle of voicing adjustments
in order to maximise the instrument’s exquisite sonic potential. Delivering a broad range of
tonal colour from pianissimo to fortissimo, and a rich variety of musical expression.

premium Neotex coating for white and black keys.
This unique material possesses moisture absorbent
characteristics to enhance touch control and prevent
mistakes, and inspires a sense of reassuring satisfaction
within the pianist.

A lifetime of happiness,wrapped within a grand piano
Preserving the treasured design of a grand piano, while pursuing new details of elegance – this is thedesign concept of the GX Series. The instrument’s exterior design, with its gentle curves and broadmusic rest, establishing the traditional characteristics and captivating form of a grand piano.
Expanding the instrument’s upper-beam thickness not only reinforces the piano’s overall structural
rigidity, but also serves to further distinguish this exterior design, with Kawai’s highly prized painting
and finishing process affording the piano body its distinctive, luxurious ebony polish appearance.
However, the beauty of the GX Series truly shines upon opening the instrument’s top-board.
The mesmerising brilliance of the glowing golden frame, the delicate woodwork and abundant
expression of quality displayed along the inner rim, the luxurious elegance of rich black felt, and thereassuring display of hand-made craftsmanship – verified by the Kawai frame mark. These are thecharacteristics that embody the spirit of ‘THE GRAND’.

Finally, the GX Series instruments feature useful mechanisms
such as multi-angle piano lid props, and Kawai’s original ‘Soft
Fall’ system, which closes the fallboard gently and slowly,
protecting the player’s hands from jarring lid accidents.

Expressive Power, Realistic Touch

All Kawai AURES and AnyTimeX instruments utilise hammer
cushioning components that allow the piano’s acoustic soundto be muted when desired. The latest AR2 and ATX4 grandpiano models incorporate Kawai’s new GP Touch Muting
System, which accurately halts the action’s hammer movement
immediately before striking the strings, without the need tomake special adjustments to let-off position or timing. This
unique design allows pianists to play AR2 and ATX4 grandpianos with exactly the same level of fluency and expression as
their standard acoustic counterparts in both normal and muted
playing modes, while also enjoying a wide range of convenientand inspiring digital features.

The AR2/ATX4’s GP Touch Muting System places thestop rail at different points along the keyboard, as close to
the hammers as possible, ensuring a firm, precise stop justbefore striking the strings.

As a result, it is no longer necessary to regulate a shallow
let-off point for the action, allowing pianists to enjoy exactly the same grand piano touch feeling in both normal
and muted playing modes.

The AR2 and ATX4 pianos’ precise hammer movements are measured with Kawai’s Integrated Hammer
Sensing System (IHSS), which utilises high-resolution contact-less optical sensors to provide greater
accuracy than conventional key-based sensor systems.
This more advanced approach reproduces themechanical flow of the upright and grand pianos’
actions more closely, allowing the full range ofdynamics to be expressed by the instrument’s
powerful digital piano sound engine with natural
fluency.

�igital piano flexibility

To ensure that AR2 and ATX4 instruments match the premium quality and excellent playability of theirstandard acoustic upright and grand piano counterparts, Kawai’s R&D engineering staff worked closelywith the company’s internal Master Piano Artisans (MPAs).
These extremely knowledgeable and experienced
technicians supervised the development process,to ensure that the instruments’ acoustic keyboard
action remains exceptionally responsive andbalanced, even when used to trigger the digital
piano sound engine.

Modern Convenience & Technology

AR2 and ATX4 instruments incorporate Kawai’s latest digital piano technologies, inherited from theflagship Concert Artist and Novus product lines.
The SK-EX Rendering sound engine uses multichannel sampling and authentic resonancealgorithms to reproduce the beautiful sound of
Kawai’s SK-EX full concert grand piano. This
stunning sound is delivered through the AR2 and
ATX4 instrument’s premium quality headphone
amplifier, allowing pianists to practise in silence,and enjoy the unique touch of an acoustic piano
without disturbing friends or family.
In addition to the acoustic muting and digital sound features, AR2 instruments are also equipped withthe latest iteration of Kawai’s advanced Soundboard Speaker System. This innovative technology utilises
four high-performance transducers which are
strategically placed onto the grand piano’s solid
spruce soundboard. These transducers channel the
instrument’s digitally generated sound through its
large wooden soundboard, resulting in a naturally
acoustic tone that is more expansive than that
produced by traditional cone speakers.

Designed to meet the connectivity needs of modern pianists, AR2 and ATX4 pianos feature standard
USB and MIDI jacks for connecting to computers or other instruments, as well as Bluetooth® MIDI
and Audio technology that allows wireless communication with supported smart devices.

Once paired to a phone or tablet, AR2 and ATX4
owners can enjoy a wide variety of exciting musicrelated apps that enhance their studying andplaying experiences, or stream high quality audio
directly through the instruments’ headphones
without the need for any cables.

The digital features of AR2 and ATX4 pianos are
exclusively controlled via the Kawai PianoRemoteapp, available for both iOS and Android devices.
PianoRemote provides a range of functions,
including sound selection and customisation,
performance record and playback with integrated
metronome, and a built-in piano music library –all accessible from an attractive user interface.
