Great Little Unit
I've waited to post a review on this piece of gear since I wanted to see how well it help up in our situation.
Sonically, it is a great-sounding unit as long as proper attention is paid to gain stages - from the source on stage all the way to the mains. I've found that using the reference mike and auto EQing the room provides a useful starting point, and best results are achieved by manually tweaking and overriding some settings.
Durability-wise, I am really impressed. We are a church that uses a school auditorium for services, and we have been loading in and out every week since 8/2008. All our gear is kept in an outside storage container all year round (New England weather). Despite the extremes in temp and humidity, this unit performs flawlessly. Of course, we allow ample time for our stuff to get to room temperature and "dry out" before even plugging it in.
It's nice not having separate EQ, comp, limiting, delays, crossovers, etc. And having presets are huge for us. We have different EQ presets for different weather conditions; what sounds nice and warm in the winter when it is dry, sounds harsh and tinny when it is hot and humid. Having the ability to recall the setting from last summer as a starting point is a HUGE plus, considering our time constraints each week.
I cannot recommend this gear enough!
