Yamaha NP31BK Portable Keyboard in Black.

The NP-31 is a truly portable piano-style keyboard, perfect for use in a wide variety of situations.

With Yamaha's Graded Soft Touch keyboard, the lower keys are heavier in touch and the higher keys are lighter, just as on an actual piano, whilst retaining the softer touch of a digital keyboard.

Advanced Wave Memory stereo sampling is a system which uses sound wave data that mirrors the tone and expression of the original instrument using advanced digital technologies. It creates a rich and expressive sound by using multiple waveforms.

This instrument uses highly efficient amplifiers that create a poweful, natural sound from a compact speaker system.

It provides performance data for piano songs as well as voice demo songs, for your listening pleasure.

The NP-31 can be used with an AC adaptor, but the 6-hour(with alkaline battery) battery is the key to Piaggero portability.

(Whether and what type of adaptors come with the product vary according to the region in which the product was sold. Please check with your local dealer)

The NP-31 comes with a new eco-friendly function that turns off the power automatically if the keyboard has not been used for a set amount of time.
