Set your LFE (.1) channel level - Usually this will be set to 0.0 dB (default). However, if you have no subwoofer
you may wish to reduce the low frequency effects (LFE) channel to lessen its contribution to the bass going to
your remaining large speakers. Or, even with a subwoofer, you may just wish to reduce the overall LFE level,
especially in an apartment situation. Note that this affects only the separate LFE (.1) channel available on Dolby
Digital and DTS material it has no effect on the reproduction of normal bass from the front, center, or surround
channels.
