Since MCACC is a common feature, I have been given the go ahead to start an
OFFICIAL MCACC thread.
There is an "Audyssey" thread where common problems get answered by their "pro's" and I am hoping that those typical MCACC questions get asked and answered here since not every knowledgeable MCACC expert hits every Pioneer thread.
The advantage is that MCACC questions could be centrally located and those questions dont bog down the individual Pioneer model threads.
Here are a few links that may give very basic info on MCACC, if you have more, let me know to include them.
I dont know how to link words to the web address, but hope posting the links works ok.

Pioneer's description of what MCACC does, click on link to see their demonstration:http://www.pioneer.eu/eur/products/4.../AF_MCACC.html
Some info using Advanced MCACC and X-Curve for a particular unit that looked informative.http://www.ultimateavmag.com/avrecei...er/index1.html
Pioneer has downloadable "MCACC Software Manuals" that give more information. For the time period (time delay), there is a complete section on that subject ("Deciding the time period for Advanced EQ Setup calibration") on page 19 in both manuals I looked over (2 pages).
The manuals can be found on this page: http://www.pioneerelectronics.com/PU...eivers.Default

"OK....This is what I feel I know about the proper work flow to get the most out of MCAAC after reading the receiver manual and the Advanvced MCAAC manual
. This is also the work flow I plan to use this weekend when the wife gives me a few hours alone in the house.
1) Set Reciever to MCAAC preset 1 (M1). Now Run Auto MCAAC with mic in you listening position (I taped the mic to the top of a two foot long shoe horn, and stuck the shoe horn inbetween the couch cushions, so the mic is right where my ears are during listening).
2) Go into Manual Sp Setup and change the SP settings if neccessary(crossover to 100hz for me and speakers to small)
3) Now re-run Auto MCAAC but select custom, and then select Keep SP settings. You will also be given the options to have MCAAC calibrate for symmetry, all ch adjust and front align. You may save each calibration to seperate presets or run just one of them, or run two of them. You will see these options after you select Keep Sp settings.
4) Now you have an Auto MCAAC calibration(s) saved to M1 (or to multiple presets if you chose more than one EQ calibration type in previous step: symmetry, front align, and all ch adjust) (....note: you must select which preset you want Auto MCAAC to save calibration data to before you enter the audio setup menu.) Now go into Data Management--------> Data Copy and copy M1's data to as many other free presets as you like.
5) Now go into Manual MCAAC--->EQ Professional------>Reverb Measurement and get a reading on the the frequency response characteristics of your room. Be sure to select EQ OFF(standing waves not controlled for via MCAAC fliters) in the Reverb Measurement menu because you don't want the standing wave adjustements (EQ on) to be factored in to the room reverb measurments. Also make sure you haven't moved the mic.
6) After test tones are done, go into Manual MCAAC--->EQ Professional------>Reverb View , and you can analyze the frequency response of individual channels at various frequencies. Based upon that data, you would select the appropriate capture delay time for MCAAC to capture data during for the upcoming EQ calibration.
Change that time frame under Manual MCAAC--->EQ Professional------>Advanced EQ Setup to whatever you decide is the appropriate capture delay time ....(Pioneer recommends 30-50 ms, but they encourage you to analyze the data under reverb view first and refer to the advanced MCAAc software manual for analysis purposes). Note: the default capture delay time is than 80-160 ms.
7) Change to the appropriate MCAAC preset before you run the new advanced EQ calibration with the new capture time. You choose which preset, but I would recommend a preset that is a carbon copy of an auto MCAAC calibration so that you can do an A-B comparison between auto EQ and advanced EQ. Go under Manual MCAAC--->EQ Professional------>Advanced EQ Setup to start the advanced EQ calibration, and MCAAC should make a more accurate calibration since it will now capture sonic information sooner after the speakers output sound, and get a read on what the frequency response is of the speakers themselves, and not the speakers and all the reverb which accumulates as time passes. (Default capture time is 80-160 ms and thus collects more reverb and less true speaker reading)
Now you should have an accurate calibration. Also, now you can easily compare the Auto MCAAC EQ effects that are stored in a preset with the advanced EQ effects in other presets while listening to content with a simple button press on the remote. You could also juice the base a few db in a preset, and also compare running the base a bit hot to a flat calibration that you have in other presets.
Advanced MCAAC Manual (especially read pages 18-20)
VSX-1018 owners manual (especially read pages 38-50)
If I am wrong about something (which is possible), let me know. I did this so that folks looking to get the most out of their equipment could better do that. The whole Auto MCAAC thing can be a bit confusing, so maybe you can benefit from my research and tinkering."
Note: Auto MCAAC select delay capture time based upon you rooom ,and I have no idea how it does this or how to know what it chose as a delay time. that is why I recommend using advanved EQ.
