Compact and Innovative
With a depth of only 232 mm, it fits into any living room, bedroom, or studio space. Despite its compact size, it will surely fill the room with sound – the redesigned speaker system delivers excellent sound optimally and ensures stronger localization and presence. The Smart Scaled Hammer action is designed to guarantee a playing feel like an acoustic keyboard instrument despite its small size. Each of the 88 keys has its own weight feel and timing, enhancing authenticity.
Bluetooth Adapter
Enjoy the full spectrum of the instrument thanks to the new Bluetooth Audio & MIDI adapter: select sounds, change settings in a flash, 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 – individually calculated for each of the 88 keys. It follows the physical differentiation: areas with different weightings.
Bluetooth
Simply accompany your favorite pieces: through the speakers of your CASIO PX-S1100 or PX-S3100, you can play music stored on your smartphone, for example. Play with different sound modes – e.g., the surround effect for spatial sound experience.
Keyboard Stand
The very stable, double-braced keyboard stand offers secure support for all common stage pianos, master keyboards, portable keyboards, and synthesizers up to a maximum of 30 kg. Thanks to its extremely robust construction, it is also ideal for tough everyday use on stage. The practical quick-release allows easy adjustment to 5 different heights. This way, every musician achieves an ergonomic and comfortable playing posture. The sturdy rubber cuffs provide absolutely slip-proof and scratch-resistant support, and the practical parquet floor protectors (4 on the feet and 2 on top) ensure more stability even on uneven surfaces. To shift weight or balance, the rubber protectors can be rotated and adjusted as needed. For long stand life, all metal parts have a durable powder coating. Of course, it is completely disassemblable for easy transport and space-saving storage in no time.
Comfortable Stereo Headphones
The KH-238 delivers full, balanced sound with rich bass reproduction and clear highs. It offers plenty of volume yet clean and precise stereo imaging. The softly padded, wide headband is length-adjustable with 12 steps on each side for optimal fit. For even more comfort, the ear cups are mounted on two axes for rotation. The thick, soft padding of the circumaural cups also provides good external noise isolation. The integrated volume control on the cable is always at hand, simplifying use with PC or mp3 player. The 3.5 mm stereo jack plug delivers excellent transmission properties, and a 6.3 mm stereo jack adapter (nickel-plated) is also included.
Piano School
The instrument is introduced and explained to beginners in a playful, relaxed way. Starting with well-known, simple melodies up to two-handed playing of complete songs, various theoretical knowledge is also conveyed alongside. Reading notes, rhythm, dynamics, and much more are covered alongside the exercises. Moreover, the simple exercises guarantee quick learning success.
