The NUX NPK-20 is our latest powerful portable digital piano. Building off the sound and feel of our bestselling NPK-10, 

the NPK-20 further optimizes the acclaimed NUX WKJ-03 keyboard and makes it feel even more natural. 

Fully loaded with 271 high-quality sounds in 7 groups, the NPK-20 is also equipped with an automatic accompaniment function for dynamic performances,

 professional effects based on advanced audio processing technology, and even a dynamic mic input for a perfect performance solution.

The Grand Piano Feel Within Reach

The NPK-20 uses our WKJ-03 Triple-Sensor Graded Hammer-Action Weighted Keyboard (with escapement and synthetic ivory and ebony keytops), and has further optimized its key touch curves and sound design. More professional processing has been made for its key touch in terms of downforce, rebound recognition, legato recognition, etc. The sense of escapement and the balance of the black and white keys are also more even. Moreover, the NPK-20 has added a key noise reduction design. Ultimately, it meets all kinds of playing and performance needs, and restores the real touch of a grand acoustic piano.
