I am having problems with getting bass management to work correctly.

I have been using Revel stereo test signals on three pieces of source equipment (to rule out any singular source component) set to stereo default for playback mode (so bass management should be functioning). All the tones are 20Hz to 100Hz and no matter what I do settings wise (so far) the tones always go to both the speakers and the subwoofer. I first noticed this issue because, despite setting the bass levels to 80 dB SPL along with all the other speakers in my system in the setup portion of the Meridian program, all the material I played through the subs was too low in volume, and when I went to equalize the subs with the Revel disc (which are balanced to be at the same volume level) there was a ~5 Hz difference in volume.

No matter what I set the bass crossover and LFE settings to (80Hz all the way down to 35Hz), it was letting all the bass signal through to both the speakers and the sub no matter what frequencies I played from 20 HZ to 100 Hz (warble tones with 3Hz bandwidth). I've tried everything I can think of and have talked to the USA branch of Meridian whom had no idea what to do (and weren't very helpful at all unfortunately) and I am currently in contact with the UK tech support office, but they haven't gotten back to me yet. I've tried everything I can think of to get the crossovers to work, but so far no good.

I have previously had issues with trying to download my HDMAX420 settings in the unit and had to hand program those in myself using the telephony in Windows XP. I am worried that there are other areas of my 861 with similar issues, as that would seem to explain why it isn't properly using the settings I am giving it (as it wasn't with the HDMAX420, despite downloading it, saving it, and uploading it to my computer whenever I asked for it). It seemed to save the settings, but wouldn't use them for some reason. I hope this isn't happening here, but it appears to be an option. Also when I sometimes download the software from the 861 back to the computer it will occasionally mess up the download and change all the equipment in my unit to older devices/(device names) no longer used in the 861, specifically my digital input cards are changed to a card that is no longer in use.

Any suggestions would be appreciated. Also if anyone knows if there is some way to telephony program the Meridian 861, so I can see if this is the same issue I was experiencing with the HDMAX420, that might be helpful. I wouldn't mind hand programming the crossover to test this out as a possibility. At the least I can then know for sure that it was only the HDMAX420 having issues, and not my expensive 861 unit, or possibly a problem with my computer adapter cable (though I don't see why this would be the case, since the 861 is receiving and storing the file, as well as using the settings, just not apparently functioning according to the parameters assigned).

Please let me know if there is something I might have overlooked. Here is a link for my setup file as well for anyone who has easy access to their unit and is curious about my current settings: NoC.msl File Link
