I did a search and found some information, but it didn't answer my question directly, so here goes........

I have Pioneer Elite DV-45A DVD player, and an Outlaw Audio 1050 receiver. Both units allow me to set the speakers to large or small for bass managment.

The Pioneer manual says that the large/small selection only affects the 5.1 analog outs (for DVD-A, SACD). This setting has no effect on the digital output for regular CD's and DVD's. I do have the 5.1 analog outs hooked up and I use it. One of my questions is, what is the crossover frequency of this setting? If I set the main speakers to Small, at what frequency threshold does the signal get diverted to the sub? The manual makes no mention of this. So it got me wondering, does the concept of crossover frequency even come into play? Maybe whatever is recorded on the .1 track of the 5.1 material, is ported to the sub regardless of the frequency (which will only be LFE material anyway). Does any one know?

The other question is: The Pioneer allows me to set the Mains to Large and have the sub turned on. Does this mean that all information, the 5 and the .1 of 5.1, will be sent to the mains AND the .1 will be sent to the sub?

Maybe I have to ask Pioneer, but that doesn't seem so easy to do, so I'll see if you guys know.

Thanks

With the options of large and small, a crossover point of some sort has to exist. If the manual doesn't say what crossover point is being used, the only way to know for certain is to contact Pioneer and ask (which, as you say, is easier said than done) - it would be logical for the crossover to be 80Hz, but that doesn't mean that's what is being used. With all channels large and the sub on, then the only data that the sub gets is the .1 track.

on that note,i passed on a sacd/dvd/.... player because the 5.1 analog was 120hz fixed.lucky the salesman let me read the manual before i bought,but it was in the manual.

I got a reply back from Pioneer, and they say the crossover is 120hz or 150? he says 150 at the end of his message, probably 120

"If I set the main speakers to Small, at what frequency threshold does
the signal get diverted to the sub?

Pioneer: The DVD player send the low frequeancies below 120 hz to the
subwoofer out put on the DV45A.

The other question is: The DV-45A allows me to set the Mains to large
AND have the sub set to 'ON'. Will the low frequency information (the .1
of 5.1 dolby) be sent to both the main speakers and the sub?

Pioneer: If in the movie there is low ferqueance special effects in
the fron channel only and no the .1, the front bass speakers will
response to the bass of the front special effects of the movie.
the .1 channel could do nothing during that time.

Each channel of dolby digital and DTS is full-frequeance

20 to 20khz in the large mode. If small from 150 hz to 20khz. "

Yeah, sounds like 120Hz is the crossover. Not the greatest place for the crossover point to be, but at least they got back to you in a timely manner.
