What is the maximum cable length when connecting my piano to external devices?

Kawai recommends cables no longer than 3 metres for USB, MIDI, and Line connections to ensure connection quality.

When connecting a Kawai digital or hybrid piano to an external device via USB, MIDI, or Line In/Out, Kawai recommends that the cable length does not exceed 3 metres.

While it may be possible to use longer cables, Kawai cannot guarantee the quality or stability of the connection in such cases. For best results, always use the shortest cable that meets your needs.
