1st try with running REW on my Marantz SR7013 system. System consists of Martin Logan motion 40's mains, Marti When Logan XT50 center and dual SVS SB13 Ultras. I set the XOVER to ALL 250 in the receiver, mode to stereo, mains to small. REW prefs were, JAVA, UMIK1. MiniDSP HD, When running measurements with the sweep range of 20 to 80 I am getting the sweeps playing on my mains. I turned off both subs and run Left and Right settings in the prefs and I see the full 20-80 sweep in both mains. Is my receiver bad or am I doing something wrong?
