5.1 and sub ?
I'm adding surround sound to my audio equiment. I have a vintage pioneer
sx-1250 that I use as a primary system. I picked up an audiosource surround sound processor and now I'm feeding all my video sources through it and then using my pioneer as the fronts. I still have regular stereo sources hooked directly to my pioneer, fm, satellite radio and itunes. I have not added a subwoofer yet but I'm looking at that now. I'm ok with the rear and center channel speakers only being used for video as I have two big floor speakers on my main system. But I would like to have the option of using the sub with the stereo sources as well as video. So my question. My 5.1 processor has a sub out. What I don't know is if that is really a separate channel or does the surround processor just strip off the lows and send it out the sub connection. If it's the later then I can just run a sub off the pioneer. If not then I need to figure a way to have two different inputs to the sub if I want to use it with the stereo as well as the surround sound. Sorry to be long winded :-) tia. |

If your Pioneer receiver has a sub out, then it can run the sub. If it is an
older receiver, I don't think it would have a sub out. If you were to have a full size set of speakers with at least 10 inch woofers, then you would most likely not require a sub. -- JANA _____ "James" wrote in message link.net...

No, the pioneer doesn't have a sub out. It's vintage stuff, sx-1250. I
was going with a plate amp on the sub that had the filter in it so I could supply a full signal. My main speakers are dual 10 woofers. Do you know if 5.1 encoded surround sound has specifically encoded the sub channel or does the processor just extract anything below 100hz? "JANA" wrote in message ...

My main speakers are dual 10 woofers. Do you know if 5.1 encoded surround sound has specifically encoded the sub channel or does the processor just extract anything below 100hz? The 5.1 signal consists of 5 full bandwidth channels (the "5") which will have signals from nominally 20Hz upwards. The 0.1 is the Low Frequency Effects channels, which, as its name suggests is used for low frequency effects in films. In a music DVD, there may or may not be anything in the 0.1 channel. (As an aside, many music videos are encoded 5.1 even though there is nothing in the LFE channel as punters have complained if there LFE light isn't on......) The DVD player outputs the 6 channels exactly as they are, i.e. 5 full-bandwidth and one LFE. How the low frequencies are distributed to your 'speakers is a function of the bass management in your decoder/receiver. Depending on what size 'speakers you declare in the set-up, it will decide where to send the LF information *from all channels* not just the LFE. Obviously, LFE information will go to the sub (if you have one), but the sub can also received LF information from the 5 full-bandwidth channels if you set any of the 'speakers to "small". This means that you could have audio going to the sub even though there is nothing in the LFE channel (as is common with music DVDs). Alternatively, if you were to have 5 large 'speakers and no sub, the LFE information could be either discarded or sent to the mains only, or mains and surrounds depending on your particular decoder/receiver and what menu choices you have.
