I have a question regarding my Tx-NR609 and the Audyssey setup. I apologize if it's been covered in this thread or the audyssey thread but there are a lot of pages to read through.
I ran the audyssey 2eq setup this morning and when it finished I went into my settings to look at where the crossovers were set. In the menu that shows crossovers, I switched the sub setting from "Yes" to "No" and then back to "Yes". This caused my fronts to go from 100Hz to full.
It would seem that just cycling through the settings for the sub derailed my audyssey calibration. From what I have read the best case scenario here is that the front correction remained down to 100Hz and frequencies below that are not corrected.
My question is this... Did turning the sub off and back on cause a situation where I need to run Audyssey again?
Alternatively, would restoring the sub to on ("YES") and fronts to a crossover of 100Hz put me back to where I was after running Audyssey originally?
If my explanation is confusing let me know and I will try to do a better job.
In general, it's common for a system to set the Fronts to Full with no Sub attached, so that's likely "as designed".
After running Audyssey, I don't think I would be changing what speakers are connected. I've read you can tweak the individual speaker levels a bit here and there (without throwing off the calibration) but that's about it. I also invoke a Crossover of 40Hz on the Fronts and Center (since it puts them at Full Band) but I'm not sure if that's really recommended or an accepted practice.
Also, if Audyssey set your Fronts to 100Hz you might want to get them checked or replaced. It should be saying Full Band or a much lower cross-over (around 60Hz at most ... as I saw with my old speakers). Sure, your sub should compensate ... it's just saying your Fronts aren't really capable of much bass (but maybe you already know that).
I would re-calibrate real quick.
