Troubleshooting
Low notes sound wrong, or are
buzzy
If you don’t hear this in headphones:
Performing at high volumes may cause the speakers or objects near the DP-
990 to resonate. Fluorescent lights or glass doors may also resonate
sympathetically. In particular, this is more likely to occur for lower notes and
higher volumes. You can take the following measures to minimize resonances.
• Locate the speakers 10–15 cm away from walls or other surfaces.
• Keep the volume down.
• Move away from the objects that are resonating.
If you hear this in headphones:
It is likely that there is some other reason. Please contact your dealer or a
nearby Roland service center.

If you set the volume to the maximum setting, the sound may be distorted
depending on how you perform.
If this occurs, turn down the volume.
