Axiom Home Page Forums General Discussion Home Theater Help with Denon 2200 ...

I’m having trouble with my 2200. here’s my setup : a pair of M60s and a pair of small jbl for surrounds (no center, no sub), and I’m connecting the DVD2200 using 6 analog cables to an AVR 3300 [denon].

I went to the 2200 audio setup menu and setup the speakers that I have, m60s to large, jbls surrounds to small, no sub and no center. The problem is that apparently no sub signal is being redirected to the M60s. When I run the THX test from a DVD, the sub pink or white noise is not perceptible on the M60, however the center channel signal is being redirected to the m60 as it’s suppose to. BTW: when I connect the 2200 and 3300 using an optical cable (3300 is the unit decoding), I’m able to hear the sub signal on the m60s when I run the THX test.
I read the audio setup manual section again thinking I must be missing something but I couldn’t find anything.
I’m not 100% sure if the same thing is happening with SACDs, but I suspect that it is. When I play the first track of DarkSideO.T.M. SACD in multichannel, the sound of the pulsing low freq. heartbeat doesn’t sound that low, when I play the same track in SACD/stereo you can really feel the low freqs.
Any help is appreciated…

Just going by the Denon 2900 Dennis has, there may be a setting in the DVD player's menu for enhanced bass or something along those lines. You'll have to turn that on to feed the LFE (sub channel) to the fronts.

There were some posts on this a couple of months ago. I think it had something to do with the fact that in Dolby Digital the LFE channel is artificially reduced by 10dB during recording ('cause it carries LFE for 5 channels not 1) and boosted a corresponding 10dB during playback making everything sound normal... but on some (many) SACD/DVD-A players the 10dB LFE boost was not implemented for some reason.

Here's a link that talks about the 10dB thing... it predates SACD/DVD-A so doesn't talk about their implementation. Try searching on this board with something like "SACD" and "10dB" and see if that hits anything useful...

Here's the thread. Lots of meaty stuff to read :

kcarlie is right. I have the 2200 and for SACD you can bump up the bass. In the Audio Setup menu tab, go to the Bass Enhancer, granted that's for 2 channel. In addition, IIRC, there's something related to bass management that can make the bass a little anemic. I believe the posted threads refer to that as well.

I've seen the setting for ‘enhanced bass’ but it is disable. I think to enable it, I need to set the ‘Filter’ off, but this will automatically set all speakers to large and also set a sub unit and a center speaker, ...that doesn’t make much sense to me.

I was under the impression that ‘bass management’ or ‘enhanced bass’ is for sending signal to a sub(physical sub unit) from a 2channel source (stereo) SACD , DVD-a or CDs etc. Am I correct?
Hmm, I’ll play a little more tonight when I get home … thanks guys.

Here's a good review that includes a couple of paragraphs about bass management on the 2900....it might help.

ON my 2910, in the speaker volume level section there is a setting called Subwoofer 10dB gain. I click on that and get excellent subwoofer bass. Actually, I dont think that is relevant because you dont have a subwoofer, do you?

I think you just nailed the problem. When playing the stereo tracks the LF signals will have been mixed out to the mains... when playing multichannel the LF signals go out to the LFE channel and out to the... nonexistent... sub.
