I purchased this unit to replace an older analog Mackie mixer. What first got my attention was the size of the unit given the capabilities it provided. It easily fits into a backpack sized carrying case that QSC sells separately, yet has as much if not more capabilities than many digital boards twice it's size. The organization of the features is really remarkable. One button operations allow you to quickly go to managing the main mix, or the aux mix, or the effects mix, as well as several others and all generally work in a consistent manner. Any item can be managed via the touch screen or simply selected on the touch screen and adjusted with the main knob which is very convenient. Pretty much any feature you might need quick access to is available with a single key press. One interesting approach QSC took in this design was to retain analog knobs for preamp trim of the inputs. At first this seems odd until you examine the features on individual inputs and discover that in addition to the analog trim there's also a digital gain adjustment. This allows you to get more consistent control over input signals that may be too hot or too week so that your analog knobs act more consistently across those types of inputs. The nice thing is that the digital gain is stored as part of the scene so it can be recalled easily and simplifies gain staging. Scenes can be stored either to internal memory or a USB thumb drive An ethernet connection is available to set up a local WiFi connection via a normal commercially available WiFi router so that remote tablet or smartphones (either Apple or Android) can be used as extended control surfaces that can individually be limited to specific functionality. For example in our church application we have one fully enabled tablet for adjusting sound from anywhere in the room while the AV person has access only to the channel he uses. You can record to solid state drives or directly connected to most DAWs.
