Powerful sound production

Keyboardists can choose from 61 exquisitely crafted tones – including acoustic piano, electric piano and organ – so you’re guaranteed to find your favorites. Developed by expert engineers, Casio’s ADVANCED TONES allow you to experience the grandeur and flair of performance with modern ease.

Recreate the sounds of timeless instruments

Casio have analyzed the sound and structure of vintage musical instruments used in hit songs from the past to the present, and brought them to life using our unique technology. Now you’re with the band. They've even included CASIO CLASSIC TONES, allowing old to become new again. Capturing the iconic sounds of their own rich lineage of keyboard and synthesizers, such as the Casiotone 201, the CT-S1 celebrates the 1980s debut of their electronic musical instruments.

Sound that brings the room to life

Experience dynamic sounds with the CT-S1’s newly developed built-in speaker system. The innovative Horizontal Bass Reflex technology and specially designed speakers provide clear, crisp notes with a powerful bass ‘punch’ in a chic and compact form. Take your musical immersion experience a step further and lose yourself in lush soundscapes amidst the full power of surround sound. Maintain superior sound quality at any decibel with the Volume-Sync EQ function that automatically adjusts the presence of bass and treble, even at low volumes.

Also, the included 3.5mm stereo output socket allows you to plug in to practice any time of day, or night!

Simple easy-to-use design

With the pure essence of musical instruments at its core, the essential keys, speakers and minimalist design add to the CT-S1’s simple functionality and operation, so you experience the best in playability and can concentrate on the music. Available in black, white or red, the keyboard’s speaker net, with its mixed color-texture fabric, spans the length of the console, adding to the wide soundscape experience. The sleek look provides the ideal minimal aesthetic, blending seamlessly with any interior setting, and allowing your life and your music to shine.
