1-The DM-A409 and ACMH1 are functionally the same and have equal characteristics for all Audyssey EQ equalization levels.
2-LFE (low frequency effects) information is "brick walled" at 120HZ in the recording phase-set LFE for sub at 120HZ
3-After you run auto setup (audyssey) it will ask you if you want dynamic EQ and dynamic volume engaged-make sure both features are turned off at this point-esp. dynamic volume. Dynamic volume compressed the dynamics of program material in 3 steps of different severity: daytime (compression), evening(more compression), and night (most compression)
4-Dynamic EQ raised low and mid range dynamics at low to moderate listening levels
5-LFE+Main only comes into play if the FLandFR speakers are considered "full range"and set to "large"-if this is the case, than LFE information is not only sent to the subwoofer, but is also sent to the FL and FR speakers. The information sent to these speakers is "below" whatever crossover frequency you have set your "large"speakers to-example-crossover set to40HZ-LFE information sent to subwoofer also sent toFL and FR below40HZ
