I am an employee of a GM Company and work 67 hours/week. I could not write or ask something earlier because of not having time & because i wanted to try things on my own.Something that i could not do , and here i am i returned at the forum.
Anyway i don't judge you, i just tell you about me.
Now as far for your answer a BIG Thanks.
I kept what the calibrator did untouched in a preset.
BUT because even i like the sound after his work, and because i have the perfection ''illnes'' i just wanted to confirm his work.
Before him when i had done the Full Auto Mcaac myself the sound was bad.
So i called him and payed him 150 euros.Finally my concern is if i must copy his work in another preset and just do a phase or reverb measurement without affecting his EQ adjusts!
yes, that's looks like the best approach. you can manually do the phase adjustment. you can look at the reverb measurements but to do anything about them means re-running the Acoustic Professional EQ (what Auto MCACC uses) & that will overwrite the EQ your calibrator did. the reverb compensation in Acoustic Professional EQ adjusts the time after the mic 1st receives the sound until the sound for each freq band to increase in volume & level off. the time where each one levels off is used as the measurement time for increasing or reducing the freqs. so it's a test tone, measure, adjust, re-do test tone & re-measurement approach to arriving at the final equalizer settings.
this is hard to explain but I'll give it a try.
the reverb compensation automatically happens when you do Auto MCACC which uses it to do the Acoustic Professional EQ. If you re-run that, you will overwrite your calibrators EQ settings. reverb compensation doesn't accomplish anything if its a manual EQ because those freq's have already been adjusted.
you can manually do Reverb View in which you view the reverb characteristics the Acoustic EQ Professional did. or you can do Reverb Measurement, in which you actually do the measurement, so you can manually set the time delay to a desired point that you decide.
however, IMO, if the calibrator's EQ settings sound good to you, then there's no further need to do anything with the reverb measurement because he did all his EQ manually to begin with. the reverb adjustment is for telling Auto MCACC when to do its measuring & adjusting. it's superfluous for a manual EQ since it's not used nor needed because it was set manually by another method (SPL, hearing)
Phase Control: on the other hand, would be something for you to do since 1) that has no effect on your EQ settings and 2) adjusts every speaker's group delay so that sound from each driver arrives at your ears mostly in phase. that is a totally separate measurement that follows the EQ in Auto MCACC has no effect on it. and you turn on or turn off Phase Control by itself in the audio parameters. so do that one manually and then you can select Full Band Phase Control, Bass Phase Control or Off as you wish. so that one is one to do manually.
Standing Wave Filters: you didn't say if your calibrator used these in his manual measurements or not. if he did, you're done. if he didn't, you can manually run them but they are a simple form of parametric EQ for 3 bass freq's. if you don't have audio measuring software & measuring mic like XTZ Analyzer, Omnimic, REW, Room EQ Wizard, I'm not sure how you would do this by ear...you really can't know how to make adjustments to reduce bass peaks & valleys. you could try but it would be working in the dark without a real time freq response measurement. your calibrator probably could have or did use something like a real time analyzer in which case he could have set these, if he was familiar with Pioneer & knew it existed. if he didn't, you'll have to live with what he did in the graphic EQ section for the bass freq's. Standing Wave Filter picks 3 specific bass frequencies either automatically when you do Auto MCACC or you pick manually and works to reduce nulls or peaks near those selected freq's. that's why its impossible to do it manually without some form of real time analyzer. hopefully, your calibrator used them but if he didn't, if audio sounds good to you know, I wouldn't worry about it.
from your post, its very hard to know exactly what advice to give you so that you can use the tools yet not un-do your calibrator's work. none of us know exactly what he adjustment he used & did not use. you seem like a knowledgeable, nice person who just wants the best audio and looking for advice. I hope what I'm posting now helps you. its unfortunate that forum posts miss a lot of the details and you end up having to guess what the poster did or looking for. it's also unfortunate that you're caught between the things done manually & what the Pioneer would have done automatically.
I think my advice would have been to run full Auto MCACC THEN have the calibrator do measurements with THOSE presets & make his minor adjustments on each freq band. Rather than start from the beginning with a blank preset, he does his measurements, now trying to backtrack and use the other tools. maybe he did use the Auto MCACC presets as his starting point...this is not clear from your posts. if he did, you're in good shape but if he didn't, starting from a blank preset, then whatever changes you make are going to effect his work.
Hope this helps. as enthusiasts, the more experienced we become, we have more desire to see everyone get the most out of his gear. and when it looks like someone may be approaching something in a way that there not going to get optimal results. believe this or not, it's a bit painful when you try to help when you're not sure what they did, possibly could have done better or they've made more work for themselves.
your calibrator may have done a fantastic job, had used the reverb measurements, set up the standing wave filters & phase control delay as part of his calibration...and given you the best sound for your room or he may not have used them at all...we don't know. the end product is how it sounds & that's what's important. so if it sounds great to you, that's the main thing
so do the phase control, review the standing wave filters to see if he set them (you'll know because the defaults are 0.0) and review the reverb measurements (but these aren't changeable unless you re-run the Auto EQ)
I'm sorry my reply was blunt, but in the spirit of seeing someone who paid money, now asking for help, and we don't know exactly was done....I hope you understand why I posted the way I did. frustration more than anything that I wasn't sure how to help & do something positive with what you have.Edited by ss9001 - 1/26/13 at 10:08am
