If I listen to DVD-A/ SACD or DTS I would like to fed the subwoofer with high level (from amplifier speaker level) for better integration without loosing low level information.Is .1 (LFE) channel content (for DVD-A and DVD-V) different than other 5 channel LFE content ?
In other words:
I heard that if you enable the full range for mains you don’t have LFE signal, if you set up small for mains you have a signal in the LFE path.
1) Is the LFE the mixed version of mains (filtered for low frequency) ?
2) The same logic applies for center ? Do you get a mix for all 5 channels if I set up all them for small (high pass signal) ?
3) Is it true that LFE could contain additional LFE low frequency signal difference than others channel low frequency signal?
4) Can I have low signals simultaneously present in the 5 and the .1 channels ?Regards,
Daniel.

I see you posted this across at least 3 different areas. Thank god for cut and paste for consistent answers.The LFE signal is completely independent of bass management. Low Frequency Effects is .1 because it isn't full range, it's limited from approximately 20Hz - 120Hz. I use the term approximate, because as newer movies and discs come out, they are putting info below 20Hz in the channel.
Bass management is rerouting bass to the subwoofer (or fronts) for speakers that cannot handle bass below certain frequencies.After that intro, I'll answer your questions...
1) No. LFE is a discrete channel, with whatever the mixing engineer decided to put there. It might or might not duplicate information in the other 5 channels.
2) The center is no different than any other channel in an absolute sense. It has the same requirements. That it happens to reproduce dialog or the "featured" performer is just because of its position.
3) Yes. That is its intent. In the theater environment that 5.1 comes from, the .1 is strictly LFE, no other content.
4) Absolutely. The 5 channels are defined as full range, but bass management can reroute so you don't require 5 full range speakers to accurately reproduce the 5.1 material in your home.
I hope this clarifies things for you.
Regards,
I have a Sony Processor SDP E 800 with this LFE function
but I will be damned if I can get any output from the subwoofer
output....during dolby digital broadcasts from HBO.The manuals written by the Japanese for their equipment
never improves.Any suggestions?
