Complete Loudspeaker Management System does all that the PA+ can do plus it features:

• An Ethernet connection so you can connect your wireless router and use your portable device (Android, IOS, Mac, and Windows) to control the PA2 from anywhere in the room. The larger graphics and touchscreen control of your portable device make it easier to operate, too.
• An input delay so you can align the front PA speakers with the amps and instrument speakers from the back of the stage, for total band clarity.
• The Auto-EQ uses an 8-band parametric equalizer and plays short frequency sweeps for its setup, which is a lot less annoying than using pink noise, like the other DriveRack models do.
• There's a dual 31-band graphic equalizer on the input section that includes Quick Curve options so you can instantly dial in an EQ curve that'll work for you.
• The PA2 has 75 factory presets and 75 user presets.
