Touch

The GP Touch muting system (exclusively available for the GP type of piano)

The latest AURES AR2 grand pianos feature Kawai's all-new GP Touch mute system. This technology features a vastly improved hammer stop rail system, capable of precisely stopping the action's hammer motion immediately before it strikes the strings, without the need for special adjustments to escapement position or timing.

This unique design allows pianists to play AURES AR2 grand pianos with the same level of effortless fluidity as their standard acoustic counterparts, whether in normal or muted playing mode, while enjoying a wide range of practical and inspiring digital features.

Unlike conventional mute systems that stop the hammer rod at a single position, the AURES AR2's GP Touch mute system places the stop rail at various points along the keyboard, as close as possible to the hammers, guaranteeing a firm, precise stop just before the hammers strike the strings. Due to the GP Touch mute system's firm, precise stopping capabilities, it is no longer necessary to regulate a shallow escape point for the action. As a result, pianists can enjoy exactly the same grand piano touch in both normal and muted playing modes.

Integrated hammer detection system

The precise movements of the hammers on the AURES AR2 pianos are measured using Kawai's Integrated Hammer Sensing System (IHSS), which utilizes high-resolution non-contact optical sensors to provide superior accuracy compared to traditional key-based sensor systems. This technology ensures precise and reliable hammer detection for a more authentic playing experience.

This more advanced approach more faithfully reproduces the mechanical movement of upright and grand piano actions, allowing the full range of dynamics to be expressed by the instrument's powerful digital piano sound engine with natural fluidity.

The sound

Grand concert piano Shigeru Kawai SK-EX

The Shigeru Kawai SK-EX concert piano was conceived as the next step in the evolution of the art of piano playing. Earning a reputation as "Japan's premier piano", it graces the stages of concert halls and musical institutions around the world, receiving universal acclaim for its exceptional clarity and dynamic range. The SK-EX has been a frequent choice of professional pianists at prestigious events such as the Chopin, Tchaikovsky and Rubinstein International Piano Competitions. With its magnificent tone and incredibly responsive touch, the SK-EX can best be described in one word - unsurpassed.

The flagship digital piano sound engine

AURES AR2 instruments feature Kawai's latest digital piano sound technologies from the highly regarded Concert Artist and Novus product lines. When playing with headphones or with the AURES mode active, pianists can enjoy the magnificent sound of the flagship Shigeru Kawai SK-EX full grand concert piano, beautifully reproduced thanks to the advanced SK-EX Rendering sound engine.

Multi-channel sampling

The SK-EX Rendering engine uses multi-channel sampling to capture the sound from various points of the Shigeru Kawai SK-EX concert grand piano. This sophisticated sampling technique helps recreate the full and nuanced acoustic characteristics of the instrument, providing a highly realistic and expressive piano playing experience.

This modern technique not only makes it possible to record and reproduce a wider range of tonal characteristics, but also enhances the connection felt between the keyboard and the piano sound, resulting in a more lively and authentic response to changes in dynamics.

Complete resonance modeling

This naturally expressive Shigeru Kawai sound is further enhanced by resonance algorithms that model the complex tonal interactions produced by the strings and various other parts of an acoustic piano.

The SK-EX Rendering produces resonances for the sustain pedal and all 88 keys progressively, allowing the sound of the AURES AR2 digital piano to behave exactly like an acoustic piano. This progressive resonance modeling adds to the realism and authenticity of the playing experience, making it feel as if you are playing a traditional acoustic piano.

Speaker system on the soundboard

In addition to soundproofing and digital sound features, AURES AR2 instruments are also equipped with the latest version of Kawai's advanced soundboard speaker system. This innovative technology uses four high-performance transducers strategically placed on the solid spruce soundboard of the upright or grand piano. These transducers route the sound generated digitally by the AURES AR2 instrument through the large wooden soundboard, resulting in a natural acoustic tone that is more extended than that produced by traditional cone speakers.

Pianists can take advantage of the flexibility and convenience offered by a digital piano, such as the ability to select a wide range of different instrument sounds, record and replay their performance, or freely adjust the volume level to avoid disturbing their loved ones - all while continuing to play with the exceptional Millennium III upright or grand piano keyboard actions of the AURES AR2.

Duplex scale

DUPLEX SCALE SCALE

The instrument's duplex scale system provides harmonics in the midrange and treble, adding depth and breadth to the overall sound.

AGRAFFES

The staples ensure precision in string alignment, spacing and angles to produce a more uniform tone and consistent vibratory length of each note.

HARDWOOD BRIDGES

The bridges transfer the vibration of the strings to the soundboard. The bridges in the GL series are made of solid maple or beech and are carefully adjusted and fitted to the frame for perfect string pressure and optimal sound transfer.

SOLID' (Stretcher Over-Lap Integrated Design)

The "SOLID" construction creates an exceptionally rigid foundation to support the tension of the strings. First, the windchest is mounted on the frame. Then, the windchest and yoke bar are integrated into a single structure, firmly anchored to the waistband. The extraordinary thickness of the yoke bar illustrates the structural integrity of this sturdy frame, designed to ensure stable tuning and powerful sound.

THE C.O.R.E. SYSTEM

"CORE" is an acronym that stands for "Convergence for Optimum Reflected Energy." Convergence refers to how the points of strength, including the rim, frame, and soundboard, all come together towards a central point at the core of the instrument. This convergence creates the foundation for an extremely powerful "CORE" central core that maximizes the sound reflection capabilities of the inner rim, resulting in exceptional sound quality.

SOLID (STRETCHER OVER-LAP INTEGRATED DESIGN)

The "SOLID" construction creates an exceptionally rigid foundation to support the tension of the strings. First, the windchest is mounted on the frame.

Our slow-close lid mechanism incorporates a dual-damping system that protects fingers and the keyboard from potential damage caused by a sudden closure.

THE KEYBOARD TRAY WITH STEEL REINFORCEMENT.

The keyboard tray must be strong and stable in order to support the weight of the entire mechanics over time. GL Series keyboard trays are made from extremely robust hardwoods, laminated and reinforced with a steel support spar that increases the strength and rigidity of the keyboard tray to prevent any loss of energy.

V-pro frame

V-PRO FRAME

The frame is the acoustically neutral metal superstructure on which the strings are tensioned. All frames in the GL series are cast using the V-Pro process. The additional strength comes from the new frame design. The result is a highly robust, stable, and elegant frame.

SMALL DOOR WITH STEEL REINFORCEMENT

The 'little door' of a piano is that long horizontal piece of wood bordering the front of the notes. Because it's made of wood, this part can twist or bend with changes in humidity, causing the keys to jam. The 'small doors' of the GL series are reinforced by a steel rod that prevents these deformations. The keys move freely, with the 'small door' remaining straight and at a regular distance from the keys throughout the piano's life.

WINDCHEST AND TUNING PEGS

The pinblock on all GL series grand pianos is fully laminated with a minimum of eleven cross-banded layers of North American hard rock maple for maximum strength and balanced torque. The tuning pins are made from the finest carbon steel, threaded for maximum continuous rotation, and nickel-plated for enhanced appearance and long-term protection.

RESISTANCE

Strength enables a piano to maintain its integrity over time. GL Series pianos have the remarkable strength to thrive under the rigors of long-term use.

Elongated fingerboards made of fir

Fir is the ideal key material - light, yet extremely strong for its weight. It responds with minimal bending and exceptional consistency, conveying every subtle nuance of the pianist's interpretation while remaining stable through years of intensive use. The length of each key has been extended to facilitate playing and offer a more uniform response from the front to the back of the playing surface. The key shanks are also designed with a slightly higher profile for maximum rigidity and increased power.

Tone

NEOTEX key surfaces

Our exclusive NEOTEX key surface, made from cellulose fibers, offers a smooth, unobtrusive texture similar to natural ivory and ebony, as well as a semi-porous silica-filled surface to absorb natural oils and hand perspiration. Because NEOTEX is used for both black and white keys, key feel is consistent across the entire keyboard. NEOTEX resists cracking and fading over years of use, and is also resistant to static electricity, helping to prevent the build-up of unwanted dust. The result is a beautiful, durable key surface offering exceptional playability.

Rigid foundation for key travel

The hammer rail is the "backbone" of the piano's action. GX Series hammer rails are made of durable extruded aluminum with our exclusive double-beam design for added strength and stability. Both the hammer rail and wippens rail are permanently locked in place to preserve the careful tolerances of the action design and ensure consistent touch response throughout the life of the piano.

The entire surface of the hammer rail is finely notched to hold each hammer flange securely in place, ensuring optimum hammer alignment. The surface-mounted hammer flanges are made of PBT resin, allowing the action screws to remain tight without shrinking or swelling. All these meticulous design features form the rigid foundation of the GX series, guaranteeing precise key travel over time.

Solid spruce conical soundboard

The soundboard is the heart of a piano. Its role is to transform the vibrations of the piano strings into a rich, resonant sound. Kawai uses only solid quarter-grain spruce for the K series soundboards. Each soundboard is strategically tapered to maximize its tonal capacity. Only those that meet or exceed our strict quality standards are selected for use in our professional upright pianos.

Hybrid inner border (Rim Konsei Katagi)

The exclusive Konsei Katagi rim leverages different hardwoods to achieve the ideal sonic balance. For the inner rim, finely porous hardwoods are used to provide superior brilliance and projection of the high-frequency range of the sound spectrum. These are layered with wider-pore hardwoods that offer warmth and fullness to the sound. The synergy of structurally divergent hardwoods produces a powerful and pleasingly rounded sound, which is the hallmark of Shigeru Kawai grand pianos.

Vertically laminated bridge

The bridge performs the essential task of transferring the vibrations from the strings to the soundboard. GX series bass bridges are made from the highest quality hard maple or beech. Treble bridges are vertically laminated with 13 layers of maple and mogno for maximum strength and optimal sound energy transfer.
