Essential Information About the Casio Celviano AP-550 Black Digital Piano
- Hybrid wood/resin 88-key keyboard with "Intelligent" hammer action for a feel close to a grand piano.
- Multidimensional AiR sound engine, 256-note polyphony, and 26 tones including two character grand pianos.
- Advanced resonances (strings, damper pedal, key release, lid) and Volume Sync EQ for rich sound at any volume.
- 2 x 20 W amplification with 4 speakers and Bluetooth audio/MIDI via the included wireless adapter.
Celviano, the "salon piano" tradition according to Casio
Following the lineage of Celviano console pianos, the AP-550 continues the idea of a refined domestic instrument designed for expressiveness and ease of use. It adopts the aesthetic codes of an acoustic piano (sliding lid, three pedals) and pairs them with a modern interface, including the "Visual Information Bar," for discreet yet precise visual support.
Keyboard Design
88 keys with intelligent hybrid hammer action (Celviano edition): levers inspired by grand pianos, ebony and ivory-style coatings on a hybrid wood/resin material. Touch sensitivity adjustable over 5 levels and key release precision to control note endings. Dedicated fine settings: hammer response (4 levels + tone + off) and key release response (3 levels + tone) to adapt the instrument to your playing style.
Sound Quality
Multidimensional AiR source with lossless compression, 26 expressive tones (including two major grand pianos), and 256-voice polyphony. Acoustic details are modeled: string resonance, damper pedal resonance, action noises, and lid opening simulator. The sound projection is wide and natural thanks to the 2-channel / 4-speaker system powered by 2 x 20 W.
Built-in Effects
- Room simulator (4 types), reverb (8 types), Surround (2 levels), and off mode.
- Chorus (4 levels + tone) and brilliance to shape the color.
- DSP with presets according to tones, Volume Sync EQ, and optimized headphone mode.
