4.1 TROUBLESHOOTING
Please note that many technical issues can arise when converting a standard computer into a DAW (Digital
Audio Workstation). PreSonus can only provide support for issues that directly relate to the FireStudio
interface. It may be necessary to contact the manufacturer of the computer, operating system and/or DAW
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 Monday through Friday between the hours of 9am and 6pm
Central Standard Time. PreSonus Tech Support can also be contacted during this same time via email at
[email protected].
Pops and Clicks
Pops and clicks in either your Input or Playback audio are typically caused by momentary losses of
synchronization between the FireStudio and its clock source. This can be due to a FireWire card not suited for
firewire audio devices or to a lack of CPU power or available memory. Try closing all unnecessary programs,
increasing the Buffer Size in the FireStudio Control Console and optimizing your operating system for audio.
Pops and clicks exclusive to the digital inputs or outputs are typically caused when the FireStudio is not digitally
synced to the external digital device. If this is the case, ensure your FireStudio and external digital device are
properly synced.
Please consult your external device’s User’s Manual for more details on syncing it to your
FireStudio.
Flashing Sync Light
The FireStudio’s Sync light flashes red and blue when it is not synced. Check the firewire cable to ensure it
hasn’t become disconnected. If you are using an external digital device and your Clock Source is set to the
correct digital input, set the sample rate in the FireStudio Control Console to the same sample rate as that of
your master clock. If you are not using an external device to generate word clock, open the FireStudio Control
Console and set the Clock Source to “Internal”.
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 Control Console and try the different Operation Modes on the Hardware Settings
tab.
No Input Signal on Channel 1 or 2
1)
Check your mic cable. This should typically be an XLR connection.
2)
Make sure the microphone does not require phantom power. If it does, press the 48V button.
3)
Make sure nothing is plugged into the line input on the rear of the FireStudio. The return inputs on
channels 1 and 2 take precedence over the combo input on the front of the unit for channels 1 and 2. If
a cable is plugged into the return input on channel 1, then the mic/instrument input on channel one will
be inactive until the cable is removed from return input 1.
