Is the LFE channel effected at all when you set the sub level to the levels of the mains using a calibration disc like the S&V disc, VE, Avia? I have my LFE at 0 (the highest possible setting allowed for my Yamaha RXV-1200). I have matched the sub level on the Yamaha to the level of the left main using the S&V tune-up disc (-18.0 on the Yamaha). Is the LFE effected at all by doing this or does it remain unchanged? It seems like it would remain unchanged as the .1 channel acting independently from the other 5 channels but I'm not quite clear on this. Can someone please clarify?
