Got my FS2AV package arrived from empire yesterday and I've spend 3 hours setting up all the cables and placing wires behind the sofas so it'll be ready for wall mounting at the weekend. However I wasn't gone wait until the weekend now that the new toy was setup, so I thought I'll give it a quick test to see if the speakers were ok. So I called up the menu from marantz and went to the test menu and started to run the auto test. At first the rear speakers weren't working. But then I realised I've wired them incorrectly, so that was fixed in no time. Only thing I am not sure of it the sub woofer where al the speakers plug into. Both volume and bass were set at the middle and I couldn't hear anything from it while it was running the test. Also the cables which plug to the back of the amp, all were for speakers (Front+, Front-, etc.). Sub had an extra cable which was called LFE. When I checked my amp I did not see anything on the back named LFE, so I left that out. What am I doing wrong here?
