Default 5.1 and sub ?

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?


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.


SACD is an exception -- there the LFE channel is full-range.
Sometimes DVD-A LFE channels are full-range too (by mistake?)

Do I understand you correctly that SACD is 6.0, not 5.1? That's news to me.



No, it's that the .1 channel is not frequency-restricted. That doesn't
mean one is supposed to reproduce the whole bandwidth, nor that it's used.
