    If your auto calibration is off that might be messing with things as well.

    I would suggest whenever you hear that distortion to go into a Direct mode so your turning off the EQ and see if that does anything. If not then start checking speaker wires and source connections.

    Is the distortion on all channels, or just specific ones?

    Distortion seems concentrated in the fronts. I finally got (I think) a good MCACC run. Will try the music again tomorrow.

    In my HT rig I have the SC-37 and RTi A7's up front. AVR set on pure direct, Stevie Ray Vaughan - Couldn't Stand The Weather in a Pioneer Blu-ray player connected via HDMI, volume level set at -2, sub on. SPL reading at one meter was averaging 95-97 with a peak at 100dB. There was no distortion.

    Was the sound quality anywhere close to my big rig? That would be a hell no and I'm glad this is not my rig for music, but it was loud and could have gone louder.

    Run the Auto MCACC, then go back in there make manual adjustments. That should get you straight. Also the remote becomes a non-issue once you figure out how things are done. Some of the functions require you to move the select switch over to HMG or shift key. I have the SC07 so it may be a little different now. You can also address tweeter issues if you want but again you need to get into MCACC.

    As mentioned earlier I would also suggest a Uni remote like the Harmony One.

    Try this
    Walk away from it and start fresh. Read this.

    Work Flow:

    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 camera tripod).

    2) Go into Manual Sp Setup and change the SP settings if neccessary(crossover to 50hz 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.

    Thank you. This sounds like a very solid plan. I will give it a shot.
