How do I play audio from an iOS device to my Kawai piano via Bluetooth Audio?
Pair your iOS device to the piano via Bluetooth, then select the piano as your audio output in Control Centre.
Enable Bluetooth Audio on your piano (refer to your owner's manual). Enable Bluetooth on your iOS device. From Settings > Bluetooth or the iOS Control Centre, select your Kawai piano as the audio output device.
Open any music app and audio will stream wirelessly to your piano's speakers. You can control the volume using your iOS device's volume controls.
