I've read about this on DVD-A & SACD players but am not sure what exaclty it is.
Thanks

The Low Frequency Effects channel (the .1 in 5/6/7.1) is a separate discrete channel that contains only very low frequency information. It can go as high as 120Hz, but is usually 80Hz or lower. Most of the time it is played by the subwoofer (if you have one), but can also be routed to the speakers set to 'Large' by the bass management circuitry.SHood said:I have a Denon 2200 DVD-A/ SACD player feeding a Yamaha 5280 receiver. My sub is connected to my receiver through the subwoofer output, (is this called LFE ? there is only one wire to the sub).
Depends on the receiver. Many do not apply their bass management to the analog inputs. My Onkyo does not. You have to rely on the bass managment settings in the player itself if the receiver won't apply bass mgmt to the analog inputs.SHood said:Does the receiver do any of the management stuff to the signals it receives through the 6 channel inputs or does it just amplify what it gets?
It might mean that the player will mix the LFE into the other channels if the subwoofer = no, rather than just discarding the lfe channel. Maybe the manual will give some indication of how it handles it.SHood said:The only settings I find for the player are a Yes setting that a subwoofer is connected. If I chose NO does that mean that the player will not output a .1 signal to the receiver and therefore nothing goes to the sub?
there are two wires.. one goes down the center of an RCA-type cable and the other wraps around the outside of it. if you look at the connection end, it's the same. You don;t actually need a left and a right, since very low bass seems to come from all around you.SHood said:Let me know when and where I can read your article.
Also, could you explain the electronics of how the LFE signal can work without needing two wires. How can that circuit be completed?
Thanks
Some subs have left and right connections so that they can be used with the preamp-out of a preamp or some receivers. If used with the pre-out, the sub will combine the left and right inputs and you would use the sub's built-in crossover to filter out the tones above it's crossover point. When connecting to the reciever's LFE-out, you can use EITHER the left or right - it doesn't matter. You then either turn the sub's crossover off (preferred if it has switch for it), or turn the sub's crossover to the highest point since the receiver will be performing the bass management.SHood said:Yeah, OK, I see that.
But now I need to know why my sub has left AND right LFE connections.
