Frequently Asked Questions

The latency performance is very good, thanks to the driver optimization; it's competitive with interfaces costing significantly more, enabling near-real-time monitoring.
I’ve found the ADAT implementation to be reliable, but as with any digital connection, proper cable quality and termination are essential to minimize potential dropouts.
While it integrates seamlessly with Studio One, compatibility with other DAWs can be a bit hit-or-miss; check Presonus's website for the latest supported software list.
