Does this thing work as simple as Pioneer's receiver calibration? I recognize it's much more advanced, the ARC software that is, but is it relatively simple to achieve a drastic improvement. For example, once ready to go you just put the microphone in the optimal listening position and let it do it's thing similar to Pioneer's method?
Upgrade the firmware in your D2 to V1.33 -- available from Anthem's public download page. Follow the instructions the installer display's when you start it. In particular, you need to make sure you have no powered HDMI connections during the install, and you need to do a Reload Factory Defaults prior to the install.
Your Setup menu settings can be stashed in Saved User Settings for reloading after the install. However, if you are upgrading from V1.29j or older, your Video Source Adjust menu settings will not survive the install. The V1.33 installer folder also includes Live Video Settings Editor V1.30a. Prior to doing the Reload Factory Defaults for the install, run LVSE, do a GET of your Video Source Adjust menu settings and SAVE them to a file on the PC. You can reverse that process after the install to restore them as well. This and the Reload Saved User Settings can be used to restore your settings after the install.
Update your ARC application to V1.2.2 -- also available from the Anthem public download page. Your original ARC installation CD includes 2 calibration and licensing files -- with names that include the serial # of your D2 and the serial # of your uniquely calibrated ARC microphone. Open the ARC V1.2.2 folder you downloaded from the Anthem site and you will find a Setup program. Copy those two calibration files into the same folder as the Setup program. Then run the Setup program to install ARC V1.2.2. If you have previously installed an older version of ARC it will delete it.
Download the latest version of the D2 V1.3x Operating Manual from the Anthem public download page and read the new Section 3.15 in there. In particular, look at its instructions for mic positioning. You will need to position the mic to at least 5 separate locations. ARC takes measurements at each location and uses the variation it hears between the locations to distinguish room response from the inherent performance of your speakers. All the mic locations need to be at seated ear height or close to it and with the mic pointing straight up. The individual mic locations need to be at least 24 inches apart from each other. The #1 position must be at your dead center listening position and then you must alternate either side of center for subsequent mic positions.
Prior to running the ARC measurements, there is another step to do to get the test tone volumes correct:
Using your trusty Radio Shack SPL meter (on Slow Response and C weighting), go into Setup / Speaker Calibration and set the volume trim for the Front Left speaker and for the subwoofer both to 0dB. Then turn on Manual in the first line and scroll down to the Noise Level line. Adjust Noise Level until your Front Left speaker is producing roughly 75dB as measured at your dead center listening position (ARC mic position #1 -- SPL meter pointing straight up). Leave the volume trim setting for the Front Left speaker at 0dB, just adjust the Noise Level line.
[ETA: CAUTION -- Due to an apparent bug, the test tone volume produced by the Noise Level line is affected by the volume set in the Left Front speaker line. So do it as stated above: Set the Left Front line to 0dB and THEN adjust the Noise Level line.]
Now scroll to the subwoofer line. Leave that line at 0dB but adjust the internal volume knob on your subwoofer until it, too measures roughly 75dB at the same listening position. There is no need to be super precise in these adjustment -- a ball park setting is sufficient.
ARC will use the Noise Level setting you have just made to set the volume for its own test sweep tones, and the adjustment you have just made to your subwoofer's volume knob insures that it, too, can be level adjusted properly to match. If you happen to have any other speakers with internally powered amps (i.e., with a volume control on them) do the same for them.
Back out of the Setup menu. Run the ARC application.
Prior to doing ARC measurements, you must tell ARC what speakers you want it to use -- e.g., whether or not you have rear speakers for example.
If you decide you want your Music speaker configuration to be distinct from your Movie configuration then ARC will do 2 entire passes, i.e., you'll need to reposition the mic all over again for the Music pass.
Setting up ARC goes in 4 steps. First you take your Measurements. Then ARC Calculates its correction parameters. Then ARC Uploads those to the D2. And finally you need to go into Setup / Source Setup for each D2 input and turn Room EQ = ON. The ARC Upload will also change your speaker cross overs and your speaker volume levels. After doing the ARC Upload, it is wise to do a Save User and/or Installer Settings to record those changes in the memories. Then if you ever need to Reload Saved Settings you won't accidentally undo the settings ARC calculated for those. ARC also uploads room correction parameters which you will not see in the Setup menu, but which are there nonetheless.
Your Listener Position (i.e., speaker distances) and the Polarity and Phase settings for your subwoofer are not modified by ARC. You need to set those manually. You can set those either before or after doing the ARC measurements and upload of results. The ARC results will just work better once you've made the correct manual settings for those.
But don't fiddle with your Speaker Configuration, or cross overs, or Speaker Calibration settings as that will mess up what ARC has set up. You can, of course, always re-do the ARC measurements and upload new results. If you still like your most recent measurements, and nothing needs to be changed in the speaker configuration ARC used for those measurements, then there is no need to re-Measure. Run ARC in Advanced mode, open the file it saved with the measurements and calculations and just re-Upload that. This will also correct any Setup menu changes you made by mistake after the last ARC Upload.
ARC can be run in Advanced mode to get more control over the process. I recommend you do that. In Advanced mode, you tell ARC when to Measure, when to Calculate, and when to Upload. You can also view the Targets window which will show you some of the decisions ARC has made in its calculations. I strongly advise you don't change any of the Targets settings on your own. Go with what ARC suggests. In particular, do *NOT* raise the upper EQ frequency above 5KHz. Even though increasing it makes the calculated results curves look better above 5KHz that result is misleading. Frequencies that high are too directional, which means what the ARC mic picks up at the different listening positions contains variations that have nothing to do with what ARC is really looking for. I.e, there's no good data for it to use up there as regards room response.
