TECHNICAL INFORMATION
5.1 TROUBLESHOOTING
Many technical issues can arise when converting a standard computer into a digital audio workstation (DAW).
PreSonus can only provide support for issues that directly relate to the FireStudio Lightpipe interface and
Studio One Artist software. It may be necessary to contact the manufacturer of the computer, operating system,
and third-party DAW software to obtain additional technical support. PreSonus does not provide support for
issues regarding operating systems, additional hardware, or non-PreSonus software. Please check our Web site,

hours via email at techsupport@presonus.com.

Flashing Sync Light
The FireStudio Lightpipe's Sync light flashes blue when it is not synced. Check the FireWire cable to ensure that
it hasn't become disconnected.
Audio Dropouts
Audio dropouts can occur when the speed of your processor cannot process the audio buffer fast enough.
Increase your buffer size in the Universal Control and try the different Operation Modes.
