We advise using a Roland PSB-1U or a PSB-100/120/230/240 Series* power supply only. These PSB power supplies are voltage regulated and 3rd party power supplies can cause the unit to not operate properly.
A new PSB power supply can be purchased through a local dealer.
*The compatible voltage of the AC cord varies depending on the country/region. For more details, please contact the distributor or support in your area.
Caution: The use of any other power adapter may cause malfunction and/or damage to the product.
