|
|
Case | Cause/What to do |
|
|
|
|
| If you can’t hear the prob- |
| lem in the headphones: |
| When playing at high vol- |
| umes, resonance may oc- |
| cur in the piano itself or in |
| objects near the piano. At |
| times, other objects in the |
| room, such as fluorescent |
| lights or glass doors, could |
| start vibrating. Such phe- |
| nomenon becomes more |
| prevalent when sounding |
| the lower frequencies at |
Bass notes sound wrong/ | high volume. To minimize |
buzzing or vibration oc- | such unwanted resonance, |
curs | please observe the follow- |
| ing: |
| - Locate the instrument so |
| it is |
| walls. |
| - Reduce the volume. |
| - Increase the distance |
| from the object that is |
| resonating. |
| If you can hear the problem |
| in the headphones: |
| The problem may be for a |
| different reason. Please |
| contact your dealer. |
