Frequently Asked Questions
While it packs a punch for its size, the Class-D design means it'll have slightly less headroom than a comparable Class AB amp at very high volumes.
The display is reasonably bright, but direct sunlight could make it challenging to read; a sunshade might be helpful in those situations.
Presets save your preferred EQ and DSP settings for different speaker systems; customization is straightforward via the front panel controls, though more complex configurations might require QSC’s software.
