Mackie support from the parent company Loud Technology is not at all well regarded at this point. Sad as Mackie service was considered strong in the past. As one friend of mine put it "I would rather not Beta test for Loud Techs's amp designers..." If it works, you're golden. If it breaks you may be up the creek... Only way I would buy Mackie amps - is used for a heck of a deal ...
I have a set of Mackie C200 speaks that I bought recently. I like 'em but they are passive so not much can go wrong and if they were DOA - the vendor has a 45 day return. As it turned out I have q few gig's on them and they are great little top boxes.
Back to mixers ...
I have an old Yamaha EMX5000/12 which is similar to the current 5014c that I like a lot. it has a few things that I find as real, tangible upgrades over the 'box' style powered mixers
- Sweepable Mid per channel
- 2 Aux sends (2 monitor mixes down the road)
- 2 on board effects engines and 2 sends per channel
- mono out with low pass for driving a sub
Has the same 500 watts per side into 4 ohms. Very flexible i/o options alows you to rent or buy powered speaks down the road, and incorporportate them into your setup as mains or monitors very easily.
The down side to either Yamaha is that you need to add 1 external EQ if you are running both mains and monitors off the thing. Not a huge deal as used rack EQ's abound but there you go ...
If you can find the model I have used, I highly recommend it.
