If it is that one, definitely return it. I have one that I used for a few weeks and got quite good in using it with REW but concluded that using Audyssey XT32 Sub EQ can do a better job quicker. So it had been back in the box and a few years and then I used it in one of my stereo setup just to set crossover, after I got rid of the Marantz AV8801 and use an ext. dac directly with a power amp.
I have no idea why so many people opted for the 2X4HD when they already have the likes of Audyssey, YPAO, ARCG and even Dirac Live. Some firmly believe they need one because they have 4 subs, that's really misguided IMO, though in that case there is some merit to me, but only in limited sense and could do worse too for those who don't know enough. It's probably hearsay, and/or groupthink that got the 2X4HD so popular, not that it is not useful, it actually is, but to use it under the conditions I mentioned, it is a waste of time and money, for negligible improvements if any and only if used wisely. That's of course just my opinion, but is largely based on facts and figures too.
