Eric A:

When I'm playing a 2ch source the only speaker active icons illuminated are L, R and Sub, which I believe is as it should be. My question was more about if I should be able to turn off the surround static icons altogether, which I thought I should be able to, leaving only the L, R and Sub static icons, but as I mentioned in my first post: With this setup:

Front L/R: Large
Center: None
Surr L/R: Large
Surr Back L/R: None
Subwoofer: L/R + Sub

The only choice for Surr L/R is Large or Small
The only choice for Sub is None, L/R+Sub or LFE Only

With this:

Front L/R: Small
Center: None
Surr L/R: Small
Surr Back L/R: None
Subwoofer: L/R + Sub

The only choice for Surr L/R is Small
The Sub is L/R+Sub or LFE Only, depending on which mode the sub was in before I switched the mains to small and it can't be changed.

Up until now, I've never seen the Sub switch to "Yes". Then I enabled the center channel and got this:

Front L/R: Small
Center: Small
Surr L/R: Small
Surr Back L/R: None
Subwoofer: Yes

I thought Aha! the bass management should now work the way I thought it would. But unfortunately I still get a full range signal from the sub if I'm using a 2ch analog source in stereo mode. If I switch to any other surround mode except Bypass, Stereo or Upsample or use a digital input, then it works as expected with only the frequencies below the xover point being sent to the sub; But then I'm no longer listening to a simple stereo signal with a sub and analog input, which I don't believe is an unreasonable expectation.

I'll keep experimenting, but for the time being it still seems that if I want to listen to an analog 2ch source, in stereo with a sub, I will need to get an active sub with it's own xover and adjust it accordingly. If that is their design decision that's cool, you have to draw the line somewhere, it's just not what I expected from reading the manual before I made the purchase. Please refer to my previous quote
