CA 901

The cabinet design of the CA901 beautifully reinterprets classic acoustic piano aesthetics, featuring a slim side profile and a premium slow-fall key cover (fallboard). It is available in three elegant satin finishes: Premium Rosewood, Premium Satin Black, and Premium Satin White — as well as the luxurious, high-gloss Polished Ebony.

When you purchase the CA901, the package includes:

• The CA901 Digital Piano (with integrated Grand Feel Pedal System and TwinDrive Soundboard)
• The power adapter and power cord
• The owner's manual and assembly instructions

The CA901 is equipped with the flagship Grand Feel III wooden-key action. Drawing on Kawai's 90 years of acoustic piano craftsmanship, all 88 keys are crafted from long, solid pieces of wood and pivot on a central balance pin — exactly like an acoustic grand piano.

The keys are physically longer than on any other digital piano action, ensuring a beautifully balanced touch weight and leverage even when playing deep near the back of the keys. It also features graded hammer weights, integrated bass counterweights, Ebony & Ivory Touch key surfaces, a 3-sensor system, and authentic let-off (escapement) simulation.

The beautiful voice of our premier Shigeru Kawai concert grand is at the heart of the CA901, reproduced in two distinct variations powered by our state-of-the-art SK-EX Rendering sound engine:

• SK-EX Competition Grand: Newly sampled from a latest-generation Shigeru Kawai concert grand specifically prepared for international competitions. It is captured with multiple microphone positions oriented specifically toward the player's position, delivering brilliant clarity, a direct, powerful attack, and incredible dynamic range.
• SK-EX Concert Grand: Sampled from the audience's perspective, providing a warmer, more blended, classical concert-hall acoustic field.
• Alternative Voices: Powered by our Harmonic Imaging XL engine, the CA901 also includes alternative acoustic piano sounds (like the mid-sized Shigeru Kawai SK-5 chamber grand and the K-60 upright piano) alongside a premium selection of e-pianos, organs, strings, and choral voices.

The TwinDrive Soundboard System is a groundbreaking technology that bridges the gap between digital and acoustic instruments. Instead of relying solely on traditional cone speakers, the CA901 uses physical AURES transducers to vibrate a real wooden soundboard at the back of the instrument.

The wood itself acts as the resonator, resulting in an exceptionally natural, three-dimensional sound dispersion and a rich, physical cabinet vibration that you can actually feel in your fingers and feet as you play.

In addition to the physical TwinDrive wooden soundboard, the CA901 features a high-end, high-fidelity 135W (50W + 50W + 35W) multi-channel amplification system and 6 dedicated speakers.

The top-board speakers are equipped with 360° sound diffusers that project the mid-and-high frequencies evenly in all directions. This perfectly replicates the spatial sound dispersion of an open grand piano lid, allowing both the player and the audience to hear the exact same premium audio quality.

Even during silent, late-night practice, you don't have to compromise on realism. Our Spatial Headphone Sound (SHS) technology adds three-dimensional spatial depth and distance to the audio, creating a natural, open acoustic field that minimizes ear fatigue. You can customize the settings specifically for open, semi-open, closed, or in-ear headphones.

Yes, effortlessly. The CA901 features integrated Bluetooth® MIDI (Ver. 5.0) and high-fidelity Bluetooth® Audio (Ver. 5.1) connectivity. Bluetooth MIDI allows you to connect wirelessly to apps like Kawai's PianoRemote or PiaBookPlayer. Bluetooth Audio V5.1 lets you stream backing tracks, online video lessons, or your favorite songs directly from your phone through the piano's unique wooden soundboard speaker system to play along in real-time.

The CA901 features an elegant, built-in 5″ color touchscreen with a reflex-free, anti-glare surface. All settings can be accessed intuitively. You can also control the piano wirelessly via the PianoRemote app on your smart device.

For a completely purist acoustic experience, the display features an auto-off mode that turns the screen dark after a few seconds of inactivity, eliminating digital distractions.

The Virtual Piano Artisan (formerly Virtual Technician) is like having your own master piano tuner inside the instrument. Through the touchscreen interface or the PianoRemote app, you can easily customize deep acoustic behaviors. You can adjust the intensity of string, damper, and cabinet resonances, fine-tune the noise of falling hammers, and even customize the volume, tuning, and voicing of individual keys.

Yes. The CA901 features dual recording options:

• Internal Recorder: Records up to 3 songs (approximately 10,000 notes) in MIDI format directly to the instrument's memory.
• USB Audio Recording: By plugging a standard USB flash drive into the USB-to-Device port, you can record your play directly as high-quality MP3 or WAV audio files. You can also play back standard audio files directly from the drive.

The CA901 is equipped with a professional, fully-featured connectivity panel:

• Dual Headphone Jacks: 1x 1/4″ (6.3 mm) stereo jack and 1x 1/8″ (3.5 mm) stereo mini-jack.
• Stereo Line Out (L/MONO, R): Connects to external amplifiers, mixers, or PA systems in larger venues.
• Stereo Line In: Connects external devices like laptops directly to play audio through the piano's speakers.
• USB to Host: For direct MIDI connection to computers and tablets.
• USB to Device: For plugging in a USB flash drive to save recordings or play back MP3/WAV files.

No. Despite its physical wooden soundboard, the CA901 is 100% digital and never needs to be tuned. It is completely unaffected by seasonal humidity or temperature changes, providing a flawless, reliable concert-grand performance year after year with zero maintenance costs.

The CA901 is built with our finest components and is backed by our comprehensive 5-year manufacturer's warranty (subject to regional registration and dealer network terms) to ensure complete, long-term peace of mind.

While both models share the same premium Grand Feel III wooden-key action, the 5-inch touchscreen, and the SK-EX Rendering sound engine, the CA901 represents the absolute pinnacle of the series (“Premium Experience”) with the following exclusive upgrades:

• TwinDrive Soundboard: The CA901 features a real wooden soundboard on the back of the cabinet, powered by high-performance AURES transducers. This replicates the physical vibration and rich projection of an acoustic grand piano's soundboard, which the CA701's traditional speaker system cannot fully match.
• Premium Amplification & Cabinet: The CA901 utilizes a larger, heavier upright-style cabinet and an even more sophisticated multi-channel speaker setup (135 W total output) for a truly immersive, concert-hall experience.

The CA901 is a massive upgrade over the CA501 in every category:

• The Touch: The CA901 uses the flagship Grand Feel III action (with longer wooden keys and front counterweights), whereas the CA501 uses the shorter Grand Feel Compact action.
• The Sound: The CA901 utilizes the premier SK-EX Rendering sound engine (multi-channel sampling and modeling) and the physical TwinDrive Wooden Soundboard, while the CA501 features the standard Harmonic Imaging XL engine and traditional 100 W speakers.
• The Controls: The CA901 is managed via a sleek 5″ color touchscreen, while the CA501 uses a standard OLED display with buttons.
