I third that Tact / Boz has great service. I've spent many hours on the phone with Boz trying to understand the complexities of the unit and the best way to use it. They also replaced my unit with a new one (and paid for shipping in both directions) when it developed a problem.
By the way I would recommend the LinerX M31 measurement microphone to do the measurements (I have no affiliation with them). In my environment it does a significantly job than the mic included with the unit.
