Hey guys Well the sub arrived less than 24 hours after placing the order and it looks great I set all five channels to "small" on the amp and switched the subwoofer option on I then connected the sub to the amp via the low-level cable and switched it on. Oh my god was there a difference I watched Return of the Jedi on DVD and a little bit of Minority Report - I was blown away. I do, however, have a few general questions: 1. The sub is connected through the low-level inputs. I also had a high-level input connector... I was wondering in what situation would you decide to use this? 2. I was playing around the the frequency (and LFE click mode) and the gain channels... are these usually set up to personal preference? 3. Phase - I have left it at 0 degrees and couldnt really detect much of a difference when I increased it to 180deg (presumably out of phase)... I didn't really play around with it for long... under what circumstances would you set it to anything other than 0 deg? Thanks for you help guys Moby.
