I used the set-up mic to run the speaker configuration on my Onkyo TX-SR703. I use PSB Image Series speakers and sub for my 5.1 setup, with no rear surrounds. I don't have HDTV yet, and the 703 is connected to my DVD via optical digital, to my Airport Express via digital optical, and the rest (Comcast box, DS-A1 for iPod) is red-and-white RCA audio. When going through the 703's manual I came across two audio settings that I'm not sure about. 1) Low-Pass Filter for the LFE channel: 80Hz is the default, but options are for 90, 100 or 120Hz. What should the setting be for my movie, music and TV? 2) Subwoofer Mode: Options are "LFE only (THX)" or "Double Bass". I think the default is for Double Bass, but I'm not sure what it should be. Neither of these two options are set automtically by the Automatic Speaker Setup. Thanks for your time and help!
