Best way to calibrate any home theatre is to the owner's preference.

SIR ano po difference ng pag gamit sa MCACC at ung kaw mismo ung mag configure with the spl meter, decibel and etc..

To use the mcacc is a good start if you are new, but as you age with your equipment, you will start looking for certain sounds from one side or the other.  Regarding the difference between manual and auto, well kung technical syempre wala kasi you are using the same tool, however the auto configuration is designed and calibrated for an average user, since you are not, you will try out different settings in the manual mode and that is where a world of difference may appear.

i've followed these instructions from Avsforums, it seems to work okay

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)
