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 FIREBOX 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 Time.

Pops and Clicks

The light on the front right panel of the FIREBOX 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 computer 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 FIREBOX 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 FIREBOX 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 (ie; running a large number of plug-ins, etc) at low latency. Windows XP – try increasing your latency settings in the FIREBOX’s hardware control panel.

This versatility makes it suitable for various recording situations, whether you're tracking vocals, instruments, or capturing stereo mixes. Additionally, the interface features six line outputs, allowing users to route audio to external devices, such as monitors or effects processors, providing flexibility in studio setups.

The AudioFireBox includes a robust monitoring system. It features zero-latency monitoring, allowing musicians to hear their inputs without delay. This is crucial during tracking sessions as it helps performers maintain timing and stay immersed in their performance. The built-in headphone output also allows for personal monitoring during sessions.

From a build quality perspective, the PreSonus AudioFireBox is designed to withstand the rigors of travel, featuring a durable chassis. Its intuitive front-panel controls provide easy access to gain settings and monitoring functions, making adjustments simple, even in the heat of recording.

The AudioFireBox is also compatible with most major digital audio workstations (DAWs), including Pro Tools, Logic Pro, and Ableton Live. Its extensive compatibility expands its usability, making it an excellent choice for those already invested in specific software ecosystems.

Moreover, the PreSonus AudioFireBox comes bundled with Studio One Artist software, providing users with everything they need to start producing music right out of the box. This full-featured DAW offers a streamlined workflow, making it easy for beginners to dive into music production.
