So, you are using the Distribution(LFE) setting to get LFE to the speakers set to Large? At what level is it set?
Two channel signals do not contain LFE. When playing such signals, at what level are the lower frequencies copied to the subwoofers using the LFE+Main setting? Are you using the default 80Hz setting or have you adjusted it using the new Bass Extraction LPF setting to raise or lower it?
Do you use different settings for playback of two channel signals using the Dolby Surround up mixer compared to playing those same signals in Pure Direct/Direct mode or Stereo mode? Manual settings to Graphic EQ?
It seems the more questions I ask, the fewer answers I actually get in return. It is as simple as posting the settings used to adjust the sound to your liking without the reminders of the capabilities of the speakers in use.
Different DSP will give different results for sure but some signals cannot be crossed up mixed at all. Dolby Atmos and DTS:X signals cannot be cross up mixed. But, a blu-ray player set to output PCM will deliver the multichannel signals of both formats sans metadata and one can cross up mix those signals to one’s delight.
Here are my answers to this conversation because I want to know how other AV10 owners use the LFE Distribution function:
LFE Distribution –
Surround and Back: -14dB. At -14dB, it ‘appears’ to add just enough fill to even the LFE sound
in my room without making me feel like I’m in a compression chamber. Adding any more volume makes me think of Neo in the movie Matrix, expanding and contracting the matrix when he breathes.
I don't know how the LFE distribution volume settings interact with the channel volume settings. You get a range of -20dB to 0dB. Pick a low setting and start experimenting.
I don’t add any LFE to LCR. LCR is already doing the heavy lifting. My 2 dedicated Subs are already in front – between L&C and C&R.
Using LFE Distribution gives me 6 distributed Subs in the room without the need for 6 dedicated Subs. Full range speakers are needed to use this function. Using LFE Distribution the way I do requires only a little more amp power to the Surrounds and Backs, and still much less than is used by LCR. All 7 floor channels use the same drivers.
LFE low pass filter is set to 250Hz.
I may experiment more in the future. It’s not on my priority list. The settings I use may or may not work for someone else.
Special thanks to
@gene for convincing Marantz to add this function.
There is a 2ch Playback mode in the speaker settings for crossing over or adding 2 channel bass to the LFE channel. Haven’t used it yet. Nothing to say yet. See the manual.
