Next-Generation High-Quality Sound Using High-Performance LSI
AiX Professional Sound Source Provides High-Quality Tones and Rich Expressiveness
The CT-X series is equipped with the AiX professional sound source, which can produce high-quality sounds, accurately representing the characteristics of each tone from bass to treble. The exceptional computing power of the high-performance LSI reproduces the natural charm of instrument sounds, such as piano tones, making it feel as if you are playing a meticulously tuned 9-foot grand piano in a concert hall; when playing the flute, trumpet, or saxophone, you can hear the natural breath and vibrato. All of this is brilliantly presented by Casio’s professional AiX sound source.

The high-speed digital signal processor is also suitable for every type of sound, such as melodies, supporting drums and bass, or organs. Even for automatic accompaniment parts, different sounds are provided for each instrument.
High Output Amplifier and High-Performance Bass Reflex Speakers
The output amplifier of up to 15W + 15W provides strong volume output and rich bass for the electronic keyboard, and even without connecting to amplification equipment, the newly designed bass reflex speakers can deliver powerful sound.
