The "NONE" surround mode selection does no surround mode processing on the input. E.g. a 5.1 source will not be expanded to 7.1 speaker output.
I can't answer your questions on the Reverse and Copy settings you asked about as I haven't played with those. You may need to send an email to Anthem tech support.
From the manual, the Reverse function is only for the 6-ch analog input, and to make it work you must use an audio mode which DOES NOT act to raise the 5.1 channel input to 7.1 speaker output. The "None" mode would be appropriate for your case. You can set this as the default in the Setup / Mode Presets menu.
If it is still not working when you do that, then you will need to give Anthem tech support a call. Last I heard the Reverse function WAS working correctly in the V1.1x and V1.2x software versions.
ETA: At one point there was a "bug" -- or possibly this was intended behavior -- where setting the Reverse option ALSO changed which speakers got sent the Setup / Speaker Calibration test tones. I don't know if this has changed in the V1.3x software. The point is, verify correct operation by playing a disc, not by using the Setup / Speaker Calibration test tones.
I sent the following to Nick at Anthem today:
I am resurrecting an e-mail chain that was from August 2006. I recently upgraded my D1 to a D1-HD and was hopeful that Sonic Frontiers would have corrected the S/R Reverse issue in the latest round of programming for the HD upgrade.
Nope – the issue has not been addressed.
In my general settings I have the S/R Reversed and the copy to surrounds off. I have switched the outputs to the amplifier as instructed and double checked this.
My setting for the 6-CH input for modes is “None”. (I checked and THX is off).
When I switch to the 6-CH mode the sound comes from the surround speakers, not the rears as it should. The display shows ANALOG-DSP and 5.1, but I can also tell the sound is processed with more than just the crossovers. I can enter the MODE, 7, 0 command at that time and it has no impact and no display change; however, if I enter the MODE, 7, 1 command (this switches the display to “THX Cinema” but what I am hearing does not change) followed by the MODE, 7, 0 command the output then changes from the surrounds to the rears and the “processing” disappears and the display changes back to “5.1”.
In addition, at that point if I switch to a different input (say CD) and then back to the 6-CH input the sound output is back to the surrounds instead of the rears and I have to go through the macro commands again to get the correct output back.
I am disappointed that this issue, which was known nearly two years ago, has not been addressed.
One other thing that would be nice to have is an ability to change on the fly or have a macro command to turn on/off the “copy surround to rears” function. Just a suggestion - my next step will be picking up the ARC upgrade.
It will be interesting to see the reply. Back in 2006 they acknowledged the problem after they tested it in-house and I was told it was sent to their programmers to address. Looks like the ball was dropped.
Response from Anthem - not what I wanted to hear - dissapointing to me, but understandable:
The Reverse and the Copy surround-rear functions have been slated for removal. They appeared in the AVM 20 v2.1 and have little relevance today.
The Copy function was added before Dolby Pro Logic IIx existed and the only role it served was trying Pro Logic II, a 5.1-channel mode into one that used all outputs. Two point sources for one signal is not a good idea because it results in combing but some people wanted it and we added it. The reason that it's taking this long to delete it is quite frankly it's low on the priority list. Video processing, HDMI, and room correction have dominated the mean time. Indeed when PLIIx appeared, moving Copy from the menu to the mode selection list was the first thought that came to mind and may still be done - it's more of a question of how many surround modes does one need before the list gets ridiculous.
As for the reverse function, it was born out of a tendency for some DVD-A users who had 7.1 speakers to want to use the rear surrounds instead of the side surrounds, so against our instincts gave them what they wanted (there is no reason a "music" system or mixing studio should be different from a "movie" one). I suspect the desire had something to do with how DVD-A was touted in its early days, calling for five identical full range speakers equally spaced from the listener. We saw that as unrealistic from the start and put the first and for quite a while the only processor on the market containing bass management, time alignment, and THX MusicMode on the analog multichannel-in (the AVM 20). The latter takes 5.1 input and turns it into 7.1 output without re-EQing. Since then, PLIIx Music mode has appeared to address the same sources although one main difference is that it emphasizes output from the side-surrounds rather than reducing their output so that overall level is the same with rear outputs combined.
Sorry to give you this news but it was just a little demand that brought them in and almost none left that's taking them out. Unrelated reasons in making this long standing decision (predates your last e-mail although fixing the bug was then a consideration) but with just as much impact if not more due to the disproportionate support involved are innumerable calls from new users* that do not set Rears to None with their 5.1 systems yet set Reverse to Yes, wondering why there's no surround, and to a lesser degree people looking for advice on how to use both direct and dipole for the sides, having them switch according to music vs movie, yet have the same amp channel connected to both (ultimately goes back to this... the system doesn't know whether it's playing music, a movie, or music in a movie soundtrack, and when blindfolded the majority prefers dipole surrounds when they're at a distance and in a room size that's typical at home - it makes no difference whether the sound is music or an explosion).
Solution to all of the above: Remove the two features. I hate to say this in response to your e-mail but in the last couple of years I've had no indication that more than one person is using either intentionally.
*to expand on the meaning of new user, it includes the new user of a used piece, for which tech support may already have been provided when the previous user used it
