Compact And Innovative
With a depth of just 232 mm it fits into any living room, bedroom, or studio. Despite its compact size, it will reliably fill the room with sound — the redesigned speaker system projects the excellent sound optimally and provides stronger localization and presence. The Smart Scaled Hammer Action was engineered so that, despite its small footprint, it guarantees a playing feel comparable to an acoustic keyboard. Each of the 88 keys has its own weight feel and timing, which enhances authenticity.
Bluetooth® Adapter
Make full use of the instrument thanks to the new Bluetooth® Audio & MIDI adapter: select tones, change settings in no time, and play back songs from your phone or tablet.
Smart Scaled Hammer Action Keyboard
The Hammer Response simulation reproduces the key weight depending on position and playing speed — calculated individually for each of the 88 keys. The physical differentiation applies: regions with different weightings.
Bluetooth®
Easily accompany your favorite pieces: through the speakers of your CASIO PX-S1100 or PX-S3100 you can play music stored on your smartphone. Play with different sound modes — e.g. the surround effect for a spatial sound experience.

Variant Casio PX-S1100 CB Privia Digital Piano Calm Blue
This rating has been translated automatically. Original language
The operating menu is interesting but not all functions have been tried out yet. The pedal responds properly and there are 2 headphone connections, which is good for two-person playing.
The sound color is pleasing and the keys have a good feel. There are even different settings for the keystroke.
Delivery was quick and problem-free.
