Feature:
Led power meters are great. Amp. limiter works well if your peaks are out of control. Not totally transparent, but in the heat of the mix it sounds fine if you need it. Mono, Stereo, Bridge switch easy to select.

Quality:
For this price range this Amp. is amazing. Rock solid, great sound.

Value:
Great amp. for the money, no doubt. Has many self protecting features, you can't hurt it permanently.

Sound:
For an Amp. in this class, I don't think you can beat it for sound. Very tight, clear dynamic.

Ease of Use:
Plug in and go. Even if your new at it, it's back diagrams are self explanatory.

Support:
Have not had to use Mackie support for this amp. but other questions I've had in the past we answered and dealt with quick.

Overall:
This amp. has great rear to front cooling. Two speed fan. It will power 8 - 8ohm. monitors no problem. Can handle 4ohm load in bridge. Fans will kick on high when it really gets pumping. Rock solid, totally happy with it. (no I have NOTHING to do with Mackie) But I do like many of their products....
