Technical Information

4.1 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 FireStudio LightPipe 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. Technical assistance may also be received by calling PreSonus at 225-216-7887 between the hours of 10 am and 5 PM Central Time.

Pops and Clicks

Pops and clicks in either your Input or Playback audio are typically caused by momentary losses of synchronization between the FireStudio LightPipe and its clock source. This can be due to a FireWire card not suited for FireWire audio or a lack of CPU power or available memory. Try closing all unnecessary programs, increasing the Buffer Size in the FireStudio LightPipe Mixer and optimizing your operating system for audio.

Pops and clicks exclusive to the ADAT inputs or outputs are typically caused when the FireStudio LightPipe is not digitally synced to the external ADAT device. If this is the case, ensure your FireStudio LightPipe and external ADAT device are properly synced. Please consult your ADAT device’s User’s Manual for more details on syncing it to your FireStudio LightPipe.

Flashing FireWire Sync Light

The FireStudio LightPipe’s Sync light flashes blue when it is not synced internally via FireWire. Check the FireWire cable to ensure it hasn’t become disconnected and that the FireStudio Drivers have been properly installed on the computer the FireStudio LightPipe is connected to.

If you are using an external word clock device and your Clock Source is set to “ADAT (1-4)” or “BNC”, set the FireStudio LightPipe Mixer’s Sample Rate to the same Sample Rate as your master clock device. If you are not using an external word clock master, set the Clock Source to “Internal” in the FireStudio LightPipe Mixer.

Audio Drop Outs

Audio drop outs can occur when the speed of your processor cannot buffer audio fast enough. Increase your Buffer Size in the FireStudio LightPipe Mixer and try the different Operation Modes from the Advanced menu.
