Slim, Elegant, Portable Design With the CT-S300, you can enjoy music anytime, anywhere. With a compact size of 930mm x 256mm x 73mm, 30% smaller than the CTK-3500 model, it achieves approximately 19 hours of life with alkaline batteries*. With a handle on the top of the keyboard and weighing only 3.3 kg, portability couldn't be easier. The design features rounded edges and corners, so you can use it with confidence. *Continuous operating time may be shortened depending on the type of battery and playing style. An Easy-To-Use Interface for Everyone The CT-S300 features a full-dot LCD screen and rotary dial, as well as a simple and intuitive interface with a clean layout that reduces the number of buttons. It also features a home button that allows you to return to the original screen at any time, making it an excellent multi-function keyboard with improved operability. Sound You Wouldn't Expect From Such a Compact Keyboard The 13cm x 6cm oval speaker with reinforced magnets delivers surprisingly good sound for such a compact instrument. The additional function of optimising the equaliser in parallel with the volume ensures a balanced sound from low to high even at low volumes.
