You may use the following information to troubleshoot your FA-66 issue:
POWER – BUS POWERED:
- If you are powering the FA-66 via bus power, be sure that the back of the FA-66 is set to "BUS" and not "OFF". Also note that the FA-66 cannot be bus powered via the smaller 4-pin firewire connector--only the larger 6-pin firewire connector can supply bus power. If the blue power light (“PWR”) on the front panel does not illuminate, blinks or is intermittent, then the FA-66 is not being properly powered. Try a different 6-pin firewire cable and/or a different firewire port on the computer.
IMPORTANT NOTE: We cannot guarantee that adapting from another type of connection (such as Thunderbolt, USB, Firewire 800, etc) into Firewire 400 will supply enough bus power to power the FA-66 properly. In this case, a PSB-120 power supply is required. A new PSB power supply can be purchased through a local dealer or online:
POWER – POWER SUPPLY:
- If you are powering the FA-66 via power supply, be sure that you are using a Roland PSB-1U or PSB-120 model numbered power supply only. We cannot guarantee compatibility with any other power supply. If the blue power light (“PWR”) on the front panel does not illuminate, blinks or is intermittent, then the FA-66 is not being properly powered. If you can, try a different PSB-1U or PSB-120 power supply. If the problem continues, the FA-66 will require service and will need to be sent to us for service. Service information can be found here:
