I ran YPAO in FRONT mode last, but loaded the FLAT settings from System Memory 1. Is the frequency response I'm seeing that of my last run in FRONT mode? If so, my manual edits for FLAT mode (3 YPAO runs ago) is all wrong!
I should have written more complete documentation, but that's always the last thing to get done!
You need to realise that PEQedit only shows you the filter response, but it doesn't have the information needed to tell you whether the response is correct or not (it doesn't have access to the measurements of your room and speaker response that YPAO made). Let's assume YPAO is trying to flatten the response. It made actual measurements of the in-room response with the microphone when you ran auto-setup, and calculated filters that produce the inverse
response. e.g. if you see a big dip in the filter response curve, it's there because YPAO measured a peak at that frequency and is trying to cancel it out.
Often you want to keep most of the YPAO filters, but you might not like what it did to the treble (for example). So you upload the PEQ values, add extra filters to cut or boost the treble a bit, then download the settings back to the receiver.
Or you might plot the curves to identify the extreme dips (or peaks) that might be better controlled with room treatments instead of EQ. e.g. you see a big dip in the curve at 80Hz, you might want to try and improve it by adding bass traps, moving your subwoofer to another location, etc. Then re-run YPAO and see if the dip is less. It's usually better to fix extreme problems with room treatments than EQ.
Or you might use PEQedit just to save multiple YPAO settings while experimenting if the 6 system memories are not enough (it only takes 5 seconds to upload settings with PEQedit, while Receiver Manager takes 5 minutes).
The other important thing is to know which settings you are working on, and that's different for different models. I think you have the 6190 (same as the 1800) and that only has one active set of YPAO filters at a time. It is called Front, Flat or Natural depending on the mode you selected when you ran YPAO, but that's just a name.
If you run YPAO and don't save the results to a system memory, then you only have the active copy (e.g. in Front mode if that's what you chose). If you then reload System Memory 1 you overwrite the last YPAO run and you've lost it. The active PEQ filters are now whatever you last saved in Memory 1.
PEQedit only works with the active set of filters. So either run YPAO or load a previously-saved YPAO result from a system memory (to make that set of filters active), upload the settings, make changes with PEQedit, download the changes (into the active set), then don't forget to save the modified filters (which are now active) to a Memory if you want to keep them.
Hope that makes sense.
