Just to be clear, if I come off rude that is not my intent. I'm just trying to be clear in explaining this;

Low frequency content within a speaker channel is not being redirected to the subwoofer as is the case when bass management is applied.
The AVR setting the speakers as large when using 6/8input is NOT redirecting bass from sub input to any speaker. It's just that the sub will ONLY play what is being supplied to the 6/8 sub input, and nothing else.
That underlined sentence is the opposite of what I said.
I know it is, it can't work the other way around with the 6/8 channel input unless the AVR was internally shorted. In this case you would notice more than weak/no bass.
As I said in that quote;"The AVR setting the speakers as large when using 6/8input is NOT redirecting bass from sub input to any speaker. It's just that the sub will ONLY play what is being supplied to the 6/8 sub input, and nothing else."
Try connecting an RCA cable from a stereo L or R output from any device directly to the 6/8 channel subwoofer input ONLY (all other 6/8 input jacks disconnected), and turn the AVR on to the 6/8 channel input. With the source playing - you hear content from the sub, correct?
Is there anything coming from any other channel, mains included?
If not, AVR is fine.
You can test each 6/8 channel input individually like this if you'd like. You should only hear content from channel input that is connected.
2, 3 days ago when I played MC discs, the sub info was being redirected from the sub channel to the main channels. B/C the 3600 was setting the speaker output as large. Causing to have zero bass,
Well, yesterday I had those wires disconnected, as I was playing stereo sources, both vinyl and cd, thus getting BM. Then I inserted a DVD-A disc and changed to the MC input, and unlike before, I was getting bass through the subs. Which is what I wanted, as my mains are not full range. So that would mean that the 3600 was providing straight by-pass output. But I do not know what is different now, compared to a few days ago.
Again, the speakers being set to large (which is only option) does NOT redirect any information from the sub input to the mains - or any other channel - when using the 6/8 channel. The 6/8 channel input is a straight in - straight out input, whatever is being supplied is what is being played from every channel. This is why the AVR sets all speaker channels as full range/large when using the 6/8 direct input.
Think of it this way, when using the 6/8 channel input the AVR is basically just a multichannel amplifier - except it also has a volume control.
One point I have been trying to make, is that some info in the manual is wrong...which is not uncommon when the manual is written by someone who speaks English as a second language. Which I understand, as I live in Latin America having to speak Español as well as English.
Two statements in the 3600 manual:
The 6/8 Channel inputs are "direct" inputs whose signals are passed directly to the volume control w/o any bass management processing. That statement is true.
But then this next statement can not be true, in most cases:
Thus, the speakers are always full-range and can not be adjusted.
The only way both those statements can be true is IF the player's speaker menu is configured for full-range L/R mains and NO sub. Then the input matches the output.
There are plenty of errors in HK manuals. However, both those statements in the manual are always
true. The manual is stating that the AVR speaker crossover SETTING for ALL speaker channels will be large/full range.The speakers will be supplied the full range of whatever information is sent to their channel input. It would not be a "direct" input if it were any other way.
Like I said before, it is up to the player/source device to handle bass management when using the 6/8 input.
Just because the speakers are large/full range does not mean the AVR is going to generate
a true full frequency range signal for them by stealing content from the sub channel. Once again, full range/LARGE does not mean content from the sub input is or can be directed to the mains or any other channel. It just means no bass management, whatever is sent in to each channel is what is sent out of that channel - nothing more and nothing less.
IF the player's speaker menu is configured as "sub on" and a 100 htz XO to all other channels then the AVR HAS to send the signals just as stated, sub on and 100 htz XO, or its not true analog by-pass.
Yes. The AVR is simply amplifying whatever is sent to it (and with the sub, just passing it through to sub out)
But again, your are relying on your player to actually take care of this / applying the crossovers. Your player may allow you to set a 100hz crossover for each channel, but is it actually
redirecting the information from each channel to it's sub output - or just tossing it? This is not uncommon.
I think your problem is with both your source device / it's bass management, and the source content you are using.
You had bass through the subs when using a DVD-A disc as it was multichannel, probably 5.1 - so it had a .1/LFE track. The mix obviously made good use of the sub. This was being sent right to the sub as it should.
If you are listening to multichannel content without a .1/LFE track, and/or the mix does not make much use of the sub and is keeping the low frequency content in the speaker channels - you are completely relying on the bass management of your player to send all the information below the speakers crossovers set in the player to it's sub output. If it does not, guess what, no bass.
Does your player have a digital output? Use, it. Then you can let the AVR handle bass management as your player does not seem to be doing it right. You can still leave the tone, DV, EQ and overlay surround modes off if you want a 'pure' listening experience. You will be using the AVR's DACs instead of the player.
