hi, i have been reading about the bass levels being too low in this player, but i'm having a different issue i think. I'm listening to a dvd-a in 2 channel mode. My question is that the sub doesn't seem to be kicking in under this playback config. Does anyone know what the issue is?

I noticed that in the audio confi setup, I have the dvd-audio set to 2 channel and the bass enhancement gets greyed out so I can't edit it. I have the sub connected straight in to the sub output on the 2900 and the l/r cannels connected to a passive preamp. Is there something I need to do to set enable the sub? Does the dvd-a 2channel mode not support one?

I'm baffled. Any help would be appreciated.

Thanks,

Rob

I think you will find that in 2 ch mode, no signal is available to be sent from the sub output of the 2900 (or any player). Frankly, when I am playing a 2ch DVD-A or SACD, I run the second "front" outputs through another (in my case "CD" since the 2900 serves as my redbook player as well) analog input that will provide a signal to my sub. Maybe this helps!

I don't think that is correct (the any player part at least). The 3800 has a 2-ch Bass Enhancer selection that does this. I'm guessing from the original post, the 2900 does not have this option.

If I use the multichannel mode, won't some parts of the signal go to the center and surrounds? That's what I want to avoid. I want to listen in only 2 channel mode and still be able to sent the lower frequencies to the sub. I'm beginning to think that's impossible...

Set your DVD to Multi Channel (for example fleetwood mac 5.1 hi rez);

Set the 2900 to Multi Channel;

Set your Front Speakers to Large and None to Center/Surround Yes to Sub;

Set the Filter to "Off";


Return/Return


Press Play and voila'...


Magic...


The noise level in the multi channel modes (Pink Floyd, Fleetwood, Steely Dan) is much more noticeable in CD/Stereo modes.


Do some switching and you'll see that the multi channel mode is best even using the crossovers in the dvd player ie rolling the center/surrounds to the mains.

Note that the 5.1 mix and the 2 channel mix can be quite different sounding. I'm not home to try it, but I think that using all of the rest of your setup techniques, *but* keeping the DVD-A in 2 channel mode, will let you hear the 2 channel mix and use the subwoofer to produce the lows from the 2 channel mix (i.e., the bass that is redirected from the L and R mains).


On the Fleetwood Mac DVD-A in particular, I found a *lot* more ambient information in the 5.1 mix than the 2 channel mix. It made the soundstage seem way deeper than I'm used to hearing on my system, but it seemed a little "off" at the same time. Overall, I think I prefered the 2 channel mix on this DVD-A, but it was kind of a toss up.


Anyway, the main point of this is just to point out that the mixes can be substantially different, and you should try both.


Enjoy,


Brian.

Not necessarily so. I am running 5 speakers + subwoofer but I still prefer 2-channel stereo hi-rez. Why ?


To do hi-rez multichannel "right", you need 5 identical full-range speakers, identical amplification, identical interconnects, identical speaker cables.


I have none of the above and the quality of my 2-channel speakers/amps/cables is much better than for the center/rears. I suspect there are very few people who have the ideal configuration. Doing hi-rez "right" costs money.


Not to mention the ITU standard for 5.1 -channel audio is not compatible with most HT standards (especially THX configurations)


OTOH, My 2-channel SACD player is MUCH better than my 5-channel SACD player which makes my 2-channel preference stand out more.


BTW, I won't use bass management on a hi-rez audio system. I run full range (though my mains are much bigger than my center/rears). This is an Achilles heel for SACD as BM probably works better with DVD-A than SACD. Or let me display my SACD bigotry: trying to use BM on SACD reduces the sonic qualities to that of your typical DVD-A material :)

No, fixed at 80 Hz
