ART? NOOOOO! That is some cheap schwag stuff that will make everything going through it sound like Mudd!
1st)If you gonna run that SX2 into a mixer and do not want Ground issues you’ve gotta have a DI.
2nd) If your power is dirty coming in the DI won’t mater none, as dirty power will cause all bunch of noise and bad mama jamma.
Do you have a power conditioner? If not get one. Cheapest one I’d go with is this..http://www.amazon.com/Furman-Advanced-Conditioning-Voltmeter-Isolated/dp/B001JJB2GM/ref=sr_1_2?s=musical-instruments&ie=UTF8&qid=1431414495&sr=1-2&keywords=Furman+pl+plus+dmc
3rd) Since you are running a stereo setup(Just one SX2?) you will need a stereo DI(or 2 mono DI’s) and the cheapest one with the best sound will be this….http://www.amazon.com/Radial-JDI-Duplex-Stereo-Direct/dp/B0002GIRM0
4rth) If you’ve already bought that ART either do 1 of 2 things. Return it! Or toss it. It’s that bad. It’s like comparing your SX2 to a BEHRINGER CMD STUDIO 4a!
Remember that whatever comes out of your controller will pass through the DI. So if you chince out on the DI it’s gonna make your stuff sound bad!
