Frequently Asked Questions

While it's technically possible, the power output is better suited for indoor environments. Weatherproofing is not a feature of this unit.
The included DSP allows for basic routing, EQ adjustments, and potentially delay, but it’s not a full-fledged digital mixing console – expect more simple tweaks.
The USB connection is generally stable, but it's reliant on a reliable Windows computer and USB cable for programming; occasional driver issues can occur with some systems.
