In Reply to: Comments about the Denon 2900's bass management: posted by Striving for Musical Clarity on May 30, 2003 at 11:31:06:
“... Since the control circuitry failed on my Genesis, I've connected it's speaker directly to a separate amp off my analog preamp's sub output. On some recordings, especially SACD recordings, I've experienced a subtle longing for more from my sub. Even with DVD-A I think more sub support is needed (I'm saying this as I sit here listening to Ted Koopman's Organ Spectactular DVD-A).”During my research I found out that setting “Filter On” will drop SACD LFE 15 dB and DVD-A LFE 10 dB. I’m not entirely sure what “Filter” is. Could it have something to do with bass management?.
Also, I have been told that bass management affects both SACD and DVD-A (only one set-up needed) and that there’s no time alignment for SACD. Can you confirm this?
Is there time alignment for DVD-A?

Lars, this is a duplicate of a Hi-rez highway response to a similar question by Jim Pierce (the answer to your question on time alignment is noted on the bottom of this posting):I did indeed have the filter set to 'on' (oops). With the filter set to 'off' (recommended when playing SACDs and DVD-As) I do get viable subwoofer output.
One caveat though, with the filter set to 'off', I believe that bass management is out of the picture (80hz rolloff from the mains with the low freqs sent to the sub) for both SACD and DVD-A. There's every indication that all freqs are sent to the sub with no speaker rolloff. Indeed, the manual does say, "Set this to play 6-channel sources recorded in all-channel full band frequencies", - and - "When "OFF" is set, the speaker size is set to "LARGE" for all the speakers and the subwoofer setting is set to "YES".
Having all speakers including the subwoofer presenting all frequencies, this setting does muddy the waters a bit (especially without a very fast responding servo sub).
And yes, the manual does mention the bass boost. It says, "DTS recommended all-channel full band playback setting. (Note however that the subwoofer volume increases by 5 dB, by 15 dB when playing super audio CDs.)"
Now, with that said, I believe I'll just set the filter position to 'on' with all speakers set to 'large' so I can enjoy maximum music clarity (meaning no real bass management).
I don't see why Denon didn't just provide a '6 full channel/5.1 channel' switch which would have allowed bass management for the 5.1 recordings and full music passthrough for the 6 channel.
Lars, there's no time alignment per se on the Denon 2900 (audio delay (distance to speakers), but no time alignment adjustment capability. I believe Chesky puts has a test cd that will allow one to perform this manually allowing for optimum tweaking for speaker placement).
> > I don't see why Denon didn't just provide a '6 full channel/5.1 channel' switch which would have allowed bass management for the 5.1 recordings and full music passthrough for the 6 channel. < <BUT that's EXACTLY what the "filter" IS !!
i.e. All it does is to change between "5.1" and "6.0" modes.
Rationale: Obviously in 6.0 (i.e. full six-channel recorded music) you need a full-frequency bandwidth capability from ALL six analog output jacks [to six equally sized full-range (i.e. "large") speakers].
Also, all the six channels must have equal volume level. This is why you get the so-called "boost" to what would otherwise be the LFE channel.
But it’s not really a boost, because all it does is equalise (i.e. raise by ~10dB) the sixth channel to the same as all the others.
setup that resulted in bad setup and wrong conclusions.
...Wouldn’t you get the purest audio with Filter set to OFF?
