I looked in the user manual and it doesn't explain it at all as far as I saw... maybe I missed it. It only says the feature can't be used unless the front speakers are set to full. Well my front speakers need to be cut off at 60Hz, so I guess I can't use this feature... but I'm still curious why I can't and what I'm missing?
On the subject of cross overs, am I correct in assuming that if, for example, I'm listening to a 5.1 movie soundtrack, if I have my front speakers cut off below 60Hz and my sub set to play 60Hz and below, that the UMC-1 sends all front channel sound track info below 60Hz to the sub? Same thing with the center and rears? So basically the sub is playing the LFE track plus all 5 other channels?

Well I just saw there was a whole thread about this from a few days ago but there never were any official answers... just speculation. I guess I need to email or call Emo and post the answer here. Shame it can't just be in the user manual to begin with though.
Based on what I've seen my best guess is that 'Enhanced bass' sends the LFE channel to the mains so that it gets reproduced by both fronts and the sub for 'extra' bass. If you don't have full range speakers then that's not an option.

True... but you should set your sub to a higher frequency than 60 Hz to avoid a missing band of frequencies where the signal could potentially be lost.
For example, my processor is set to crossover at 80 Hz but my sub is set to 100 Hz so I make sure that information between 60 and 100 Hz is not lost.

For example, my processor is set to crossover at 80 Hz but my sub is set to 100 Hz so I make sure that information between 60 and 100 Hz is not lost. I'm not quite clear on your example. What setting are you talking about when you say 'my processor is set to..'? Are you talking about the sub crossover setting on the processor vs the filter setting on the physical subwoofer itself? Why would you miss between 60 and 100Hz? I thought that if I had fronts set to 60 and up and sub set to 60 and below that the 12dB per octave slope setting would allow for sufficient overlap in case there's any gap in there? But what confuses me more is that in the other thread people were saying that the LFE channel goes up to 120Hz and so setting the sub to even 80Hz would have you missing the LFE channel from 80 to 120Hz. Problem with that is I don't like the way my sub sounds when allowed to play over 80Hz. I can localize the sound to an extent and it sounds muddier than when played through my speakers. I guess that's an advantage of the enhanced bass setting. I guess in that case I wish I could use the enhanced bass setting for my front speakers despite setting them to not play below 60Hz just so they could take care of that remaining 80Hz to 120Hz of the LFE channel. Or I might be completely misunderstanding how all this bass management works. I guess we really need a detailed explanation from Emo. Ideally an extra page or two with possibly a diagram in the final revision of the user manual. |

Yeah that's what I was referring to in my second post. That thread ended up filled with a lot of speculation about how the UMC might act based on how other processors act. I'd like to get a more official word about the UMC specifically. |

Sorry I should have been clearer.. I meant that my processor sub crossover setting is at 80 Hz but the "crossover" knob on the sub is set to 120 Hz. As I understand it, the processor sends all LFE below 80 Hz to the sub which processes everything up to 120 Hz. If I have the sub crossover control set to for example, 20 Hz, then I'd lose everything from 20 Hz to 80 Hz.
Generally, the sub crossover control is recommended to be set as high as possible.
