Kurzweil KA-S1 WH - Refurbished

A Portable Digital Piano Designed to Play Anywhere

The KA-S1 is aimed at musicians looking for a compact digital piano that is easy to transport and immediately enjoyable to play. Its purpose is clear: to offer the essentials of a modern piano keyboard in a lightweight format, without compromising either touch response or the quality of the built-in sounds. It is an ideal solution for serious beginners, home practice, small-group rehearsals, or anyone looking for an instrument that is easy to move.

With its white color, compact footprint and well-designed connectivity, it fits easily into a living room, home studio or mobile setup. The KA-S1 focuses on quick and easy operation, while offering enough features to support the musician’s development over time.

Keyboard Design

The KA-S1 features an 88-key semi-weighted hammer-action keyboard, designed to provide a feel closer to that of a piano than a traditional lightweight keyboard. This type of mechanism is an excellent compromise for pianists who want to regain a certain amount of resistance under their fingers while keeping an instrument that is easy to transport. The 6-level adjustable sensitivity allows you to adapt the keyboard response to your attack, whether you play gently, with greater dynamics, or in an educational setting. This touch response is equally suitable for piano sounds, general keyboard sounds and versatile playing applications.

Sound Quality

In terms of sound, the KA-S1 is equipped with 16 factory programs ready to use, complemented by the 128 MB KORE 1.0 sample library. Together, they cover the essential needs of everyday playing with immediately usable sounds. The 128-voice polyphony provides genuine comfort, particularly when using the sustain pedal or Layer sound combinations. The built-in audio system delivers 30 W in total, distributed as 2 x 15 W, with 4 stereo speakers, ensuring balanced, clear and sufficiently powerful sound for personal practice, rehearsals and small spaces without external amplification.

Built-In Effects

• Reverb to add space and depth to the sound
• Chorus to enhance the width and texture of the sounds
• EQ with bass and treble controls to fine-tune the sound color
