6.2 TROUBLESHOOTING
Please note that many technical issues can arise when converting a standard computer into a DAW
(Digital Audio Workstation). PreSonus will only provide support for issues that directly relate to
the INSPIRE 1394 interface. It may be necessary to contact the manufacturer of the computer,
operating system and/or software to obtain additional technical support. PreSonus does not
provide support for issues in regards to operating systems, additional hardware or software.
Please check our website, www.presonus.com regularly for software information and updates,
firmware updates, and technical support. Also, technical assistance may be received by calling
PreSonus at 225-216-7887 between the hours of 10 am and 8 PM Central Standard Time.
Pops and Clicks
This light is a driver sync indicator, and lets you know if your unit is receiving driver sync
correctly. Proper driver sync prevents digital interfaces from having pops, clicks, or distortion in
the audio signal (due to mismatched digital audio transmission). If the symbol is solid blue, this
indicates that your unit is in sync with the computer. If the light is solid red, this indicates that the
INSPIRE 1394 does not have sync from the computer and that the unit might not be connected
properly. Here are the two different light modes broken down again:
Blue – solid sync
Red – sync not present.
Pops and clicks can also occur with high CPU loads (ie; running a large number of plug-ins, etc) at
low latency. Try increasing your latency settings in the INSPIRE 1394’s hardware control panel
(PC only), as well as any buffer settings in your software.
