Symptom Cause/Action Page
Even though you’re using head-
phones and the sound is muted,
a thumping sound is heard when
you play the keyboard
HP507 uses a hammer action keyboard in order to simulate an acoustic piano’s playing touch as realistically as possible. For
this reason, you’ll hear the hammers thump when you play the keyboard, just as you would when playing an acoustic piano.
Since this unit allows you to adjust its volume, you might notice the sound of the hammers in certain situations, but this does
not indicate a malfunction. If vibration transmitted to the oor or walls is a concern, you may be able to minimize the vibration
by moving the piano away from the wall, or by laying down a commercially available anti-vibration mat designed for use with
pianos.
