We all know that the 0.1 channel of a soundtrack is a separate/discrete channel for LFE and being reproduced by our sub. The sub would reproduce only LFE if the rest of the speakers were set to Large. But if any speaker were set to small (say at the 90hz crossover), the sub will reproduce the LFE (0.1) plus the diverted bass (90hz and below) from the speakers set to small. Now AVIA DVD has a test tone (under evaluation menu), where you can check the level of the diverted bass and the LFE. On my first test, my RS meter drop to about 10db when the tone reaches LFE. The note says that I have to set my LFE to normal or 0db on my system. So my former setting of -10db (this is the mid setting of my Yamaha RX-V800, where I can easily adjust sub level), was now change to 0db (max setting on Dolby, while DTS was up to +10db). The AVIA test again indicates a drop of about 4db on the LFE. I know that the result indicates that I have a poor bass management, since diverted basses were overpowering my LFE. I don’t know were else can I modify to make my bass properly leveled. Please help.
