Hi.
Since I already had a **another correction tool** Xref20 mic I didn't bother to buy IK multimedia's mic for measurement when I got ARC 3.
I'm trying not to make any silly mistakes when testing ARC for the first time, so my question is: at what angle should the Xref mic be when measuring? Horisontal (0 dgrs) or vertikal (90)?
Any tips appreciated.
