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 fill the room with sound—the revised speaker system projects superb tone and delivers stronger localization and presence. The Smart Scaled Hammer action was designed to deliver the feel of an acoustic keyboard despite its small footprint. Each of the 88 keys has its own weight feel and timing, which enhances authenticity.
Bluetooth® Adapter
Use the instrument's full potential thanks to the new Bluetooth® Audio & MIDI adapter: select sounds, change settings in an instant, 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. It reflects the physical differentiation across areas with different weightings.
Bluetooth®
Simply accompany your favorite tracks: via the speakers of your CASIO PX-S1100 or PX-S3100 you can play music stored on your smartphone, for example. Experiment with different sound modes—e.g. the surround effect for a more spacious sound experience.

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.
