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 FIREPOD 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,

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 5 PM Central Time.
Pops and Clicks
The light on the front right panel of the FIREPOD is a clock (sync) indicator. It lets you know if your unit is
receiving word clock correctly. Word clock is the manner by which digital devices sync frame rates. Proper
word clock sync prevents digital devices 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 PC or a S/PDIF device that is plugged into the S/PDIF input on the back of the unit. If the light is
solid red, this indicates that the FIREPOD does not have sync from the computer and that the unit might
not be connected properly. If the unit is flashing red and blue, the unit is not receiving external sync. This
would be caused by the clock source in the FIREPOD control panel being set to S/PDIF with no S/PDIF
sync source coming in. Here are the three different light modes broken down once again:
Blue – solid sync
Red – sync not present.
Flashing Red and Blue – external sync not present
Pops and clicks can also occur with high CPU loads (running a large number of plug-ins) at low latency.
Windows XP – try increasing your latency settings in the FIREPOD’s hardware control panel.
No Sync (Red) – Macintosh Users –Open Audio MIDI Setup and change the Format sample rate speed
to anything different. This will re-establish synchronization and the Blue sync light will turn on. Once you
have the blue sync light you can then reset the Format sample rate to your desired setting.
