1. In the manual it states, "Positions 2 and 3 should be symmetric to the left and the right of the centerline and the same applies to the remaining positions." Is the centerline considered you primary seating position? Can someone explain exactly what this means?
2. How far in front of your seating position can the mic be?
3. In the manual it states, "Set the mic in the first position. Don't stand near the mic while sweep tones are playing." Where can I be when sweep tones are playing? Should I leave the room?
4. Also, in the manual it states, "If you made measurements for a music configuration, assign bass manager accordingly." What does this mean?
5. Do you have to run measurements each time you update the ARC software?
1) Mic position #1 should be on the center axis from your screen at the distance of your primary listening position. Subsequent mic positions should alternate to either side of center. Like this:
#4 -- #2 -- #1 -- #3 -- #5
Each position should be at least 24 inches apart from all the other positions.
2) ARC is much more sensitive to the mic height than to its horizontal position so long as the guidance in (1) above is followed. I would think you would be fine if the mic was in front of your ear position at a given location by as much as the length of the chair seat itself for example. ARC is picking up room modes which are audio response characteristics in the room that have pretty significant size. The vertical positioning is critical because many speakers don't have particular good vertical spread in the mid-range and treble.
3) Step away from the mic by a few feet at least. Try not to stand between any speaker and the mic. A wireless mouse makes it easier to start the Measurement without being right next to the computer (which will usually be set up between the screen and the mic positions). You don't need to leave the room.
4) If you look in Setup / Speaker Configuration you'll see that you can set up a separate Music configuration from the normal Cinema (or Movie) configuration. If you do that, then for each source definition (Setup / Source Setup) you must select whether the Movie or Music configuration will be used for bass management -- really for all the various aspects of speaker management, including bass steering. This is for manual setup.
When you run ARC the ARC application asks you to specify which speakers will be used and gives you the option of setting a separate Music configuration. The ARC Upload then replaces your current Setup / Speaker Configuration with what you tell ARC to use (along with details ARC calculates such as appropriate cross overs). But if you set up a separate Movie and Music configuration you still have to decide on your own which one should be used for each Source definition. By default, all sources will use the Movie configuration.
5) Whether you need to re-Measure depends on what has changed in the new ARC version. In some cases all you will need to do is re-Calculate and re-Upload starting from your most recent set of Measurements. In general, however, if Anthem doesn't specify that you can just re-Calculate and re-Upload you should plan on having to do a fresh set of Measurements.
