At home, on stage, your music.

The Kawai ES920 and ES520 have been designed to deliver the finest playing experience possible within a portable piano. These stylish instruments are ideally suited to musicians seeking a piano that provides an authentic keyboard action and a selection of inspiring sounds, yet can still be moved easily, or placed on an attractive furniture stand without occupying too much space.

The Touch of a Grand Piano: Responsive Hammer Compact II keyboard action

The ES520’s Responsive Hammer Compact II (RHCII) keyboard action has been developed to represent the distinctive touch of an acoustic grand piano. Based on the highly-regarded RH keyboard action design, its spring-less technology and sturdy construction delivers consistent upward and downward motion for a smooth, natural, and highly authentic piano playing experience.

The weight of the keyboard is appropriately graded to mirror the heavier bass hammers and lighter treble hammers of an acoustic piano, while let-off simulation recreates the subtle 'notch' sensation felt when softly playing the keys of a grand piano. These important characteristics allow discerning pianists to practise their expanding repertoire with confidence, and ensure that there are no unpleasant surprises when called upon to perform using the finest acoustic grand pianos.

Acoustic piano key weighting

Just as acoustic pianos utilise heavier bass hammers and lighter treble hammers, the RHCII keyboard action also employs different hammer weights, appropriately graded for each playing range.

Such details provide greater stability during fortissimo passages, while preserving delicate pianissimo control, to satisfy the demands of even the most discerning pianist.

More realistic & responsive

More realistic & responsive The Responsive Hammer Compact II keyboard action utilises an accurate triple-sensor key detection system for enhanced playing realism. The added third sensor improves responsiveness when playing the same key repeatedly, and unlike conventional two sensor keyboard actions found in most portable pianos, allows the sound of a single note to be gradually ‘layered’ without the previous tone being lost. In addition, Kawai’s action technology also monitors the speed at which each key is lifted, influencing the release character of piano sounds, and providing a greater range of expression between staccato and legato playing.

The Sound of a Grand Piano: Two world-class instruments

Earning a reputation as the ‘premier pianos of Japan’, Shigeru Kawai instruments grace the stages of concert halls and musical institutions throughout the world, and are prized for their outstanding tonal clarity and exceptional dynamic range. The ES520 captures the magnificent tone of the flagship Shigeru Kawai SK-EX concert grand piano. This peerless instrument is hand-built by Master Piano Artisans at the Shigeru Kawai Piano Research Laboratory in Ryuyo, Japan, and widely regarded as one of the finest instruments in its class. In addition, the ES520 also features the distinctive sound of Kawai’s highly acclaimed EX concert grand piano, which has been selected by professional pianists in such prestigious events as the Chopin, Tchaikovsky, and Rubinstein international piano competitions, among others. Both the SK-EX and EX are faithfully reproduced with full 88-key sampling using advanced Harmonic Imaging™ sound technology, to establish a new standard in digital piano tonal quality, and allow musicians to appreciate the contrasting properties of each.

True character in every note

The rich, expressive sound of the SK-EX and EX concert grand pianos is at the heart of the ES520, with all eighty-eight keys of these world-class instruments painstakingly recorded, meticulously analysed, and accurately reproduced as high-fidelity digital waveforms. Recording each key individually in this way – as opposed to stretching the same tone over several different notes – preserves the grand pianos’ unique harmonic character, and guarantees that the sound heard when playing any one of the ES520's weighted keys is a faithful representation of the original acoustic source.

Rich, dynamic, expressive

When playing a fine piano, the amount of pressure applied to the keyboard affects not only the volume of the sound produced, but also the unique tonal character of each note. Therefore, in order to construct a realistic acoustic portrait of each grand piano, not only is each key recorded individually, but also at a wide variety of different volumes, ranging from gentle pianissimo to thunderous fortissimo. The ES520 offers a highly detailed acoustic portrait, employing Kawai’s proprietary Progressive Harmonic Imaging sampling technology to ensure smooth tonal transitions across the keyboard and throughout the entire dynamic range.

Variety beneath your fingertips

Alongside the classically voiced SK-EX and EX grand piano sounds, the ES520 also showcases a selection of Jazz, Pop, and Modern variations suitable for a range of musical genres. A traditional Kawai upright piano sound is also included, for pieces that suggest a feeling of nostalgia, or call for a slightly more intimate tonal character.

Personalised piano enhancements

The knowledge and skill of an experienced piano technician is essential to bring out the best of a fine acoustic piano. In addition to tuning each note, the technician also performs numerous regulation and voicing adjustments that allow the instrument to truly sing. The ES520’s powerful Virtual Technician function simulates these refinements digitally, allowing discerning musicians to shape aspects of the selected piano’s character to suit their personal preferences. Perform touch weight and voicing adjustments, regulate hammer and key release noises, and fine-tune string and damper resonances. It’s even possible to adjust the precise tuning, volume, and character of individual notes.

Studio quality effects & reverb

The ES520’s powerful digital effects engine enhances the instrument’s superior core sounds, applying additional layers of detail and realism that bring performances to life. Tailor an instrument’s character and feeling with a range of studio quality chorus, tremolo, delay, and auto-pan effects. Add vintage warmth to electric pianos and trademark growl to drawbar organs using the dedicated Amp Sim speaker models. Then adjust the instrument’s reverb controls to position yourself within one of six acoustic environments, ranging from a small practise room to an inspirational grand cathedral

Once paired with a phone, tablet, or laptop, ES520 owners can enjoy a wide variety of exciting music-related apps that enhance their learning and playing experience, or stream audio from songs and videos directly through the instrument’s powerful speaker system without the need to connect additional cables.

Flexible USB connectivity

The ES520 is equipped with modern USB connectors that not only allow the instrument to be connected to a computer for MIDI use, but also to load and save data to USB memory devices directly. This latter USB to Device functionality allows favourite instrument settings, registrations, and memorable recorder songs stored within internal memory to be safely preserved on USB flash drives, or for standard MIDI files (SMF) downloaded from the internet to be played back and enjoyed using the instrument’s superb Progressive Harmonic Imaging sounds without additional hardware or cables.

Additional instrument sounds

Supplementing the beautiful acoustic piano voices, the ES520 also features a strong selection of additional sounds. Vintage electric pianos, drawbar organs, and warm synth pads allow this portable piano to serve as a convenient gigging board, while church organs, strings, and graceful choir voices ensure that the versatile ES520 is equally at home in places of worship. Furthermore, the Dual playing mode also allows two different sounds, such as grand piano and strings, to be layered together, while the Split and Four Hands modes divide the keyboard into two independent sections, with volume balances adjustable in real-time from the front panel.

Superior headphone experience

The ES520’s Spatial Headphone Sound (SHS) technology enhances the depth and realism of the instrument’s sound when listening through headphones or earphones. The player can select one of three different acoustic presets that adjust the spatial positioning of the sound, while also helping to reduce auditory fatigue when using earphones or headphones for extended periods of time. In addition, the ES520 also allows players to select a variety of headphone types (Open, Semi-open, Closed, In-Ear, Canal, etc.) for an optimised listening experience.

Uncluttered appearance, lightweight body

The ES520 adopts a brand new exterior design, utilising a molded unibody construction. Its smoothly rounded edges and clean lines complement the flat, uncluttered panel surface, with elegantly recessed buttons that depress with a satisfying click. Lightweight and portable, the ES520 weighs just 14.5 kg, yet possesses a stylish, professional quality that players can trust.

Available in a smoothy, matte Black or White finish, the ES520’s clean design is appropriate for both traditional and contemporary spaces. And with matching designer stand and triple pedal accessories, the instrument can be easily transformed into an ultra-compact piano replacement for the lounge, studio, or bedroom.
