Troubleshooting
ProFire 610 has been designed to give you high performance and professional-quality audio on a wide range
of systems and operating conditions. However, there are a virtually limitless number of operating scenarios, any
of which could affect your system’s performance. While this section cannot cover all possible issues you may
encounter, we would like to offer you some suggestions for dealing with common problems.
In general, it is recommended that you avoid connecting too many FireWire devices to your computer. FireWire
is a dependable high-bandwidth protocol that is ideally suited for digital audio. Nonetheless, it’s important to
remember that audio and multimedia streaming places considerable demands on both your processor and the
FireWire bus. Although it is theoretically possible to chain multiple FireWire devices in series, doing so may result
in audio recording and playback issues.
If you are having trouble getting audio into or out of your computer, please check the following:
