Casio LK247 Portable Keyboard


The LK-247 illuminated keyboard represents independent learning and the opportunity to experience a sense of achievement. Just like during traditional piano lessons, the practice piece is divided up into individual sections of several bars and is learned section-by-section.


The microphone provided can be easily connected to the keyboard: Now you can emulate the sounds of the chart hits or record songs using the sampling function. 400 AHL keyboard voices, 150 rhythms and 110 internal pieces ensure an exciting sound mix. Hours of fun instead of boredom!
