1) You have indicated that the PC requirements are Windows XP. I have a desktop with Windows 2000 and a laptop with Windows Vista. Will the ARC work on Windows 2000 or Vista?
2) I have a Velodyne DD18 subwoofer which has Room Correction. You indicated the it MUST be running when ARC starts playing its sweep tones, otherwise ARC will not be measuring the subwoofers "real" performance. How exactly will I do that? I'm sure that the subwoofer sweep tones can't be running when the ARC is measuring the high frequencies. Will the ARC stop just before it's about to calibrate the sub and ask if my sub has room correction and if so to please run the room correction? Does the ARC not send low frequencies through the sub to calculate the LFE responses? As you can tell, I'm pretty confused about when to start the room correction for my sub when the ARC is running. Could you please elaborate?
3) How long is the USB microphone cable?
4) What's the difference between standard mode and advanced mode? Does advanced mode allow you to make changes after the ARC run where standard mode does not? If you can make changes, what changes can I make? Also, will standard mode cover everything that advanced mode covers?
5) I downloaded and installed 1.31. Is that the same version that's on the ARC installation CD?
We've had reports here of ARC working on Vista. No reports as to Windows 2000.
What they mean regarding the subwoofer is to select a Velodyne preset that has the Velodyne Room EQ stuff turned on, otherwise when you make the ARC measurements ARC won't hear what the Velodyne's Room EQ does. If you want to compare how well ARC works with and without the Velodyne Room EQ turned on, that is easy to do by selecting Velodyne Preset 6 that disables the Velodyne's EQ processing.
To get the full value of the Velodyne stuff, TURN OFF Setup / Source Setup / Room EQ for the Anthem input you use for running the Velodyne's own sweeps. This turns off ARC for that input. Then run the Velodyne stuff -- either their automated stuff or doing it manually while watching the Velodyne's response graph. After you've got the best you can get using the Velodyne's internal Room EQ, then leave those settings in place in the Velodyne and now do the ARC measurements. What ARC's mic hears will include the benefits of the Velodyne's internal Room EQ. Upload the ARC results to the Anthem, turn on Setup / Source Setup / Room EQ for each source in the Anthem, and you will now hear the *COMBINED* benefits of the processing inside the Velodyne plus what ARC does on top of that.
Remember that if you turn OFF the Velodyne's internal Room EQ, you will need to RE-MEASURE and upload new ARC results since what ARC has to do will be different with and without the assistance of the Velodyne's internal stuff.
And if you want to see what the Velodyne's response graph shows with both it's EQ and ARC working together, you will need to turn back ON Setup / Source Setup / Room EQ (i.e., ARC processing) for the Anthem input you use for playing the Velodyne's test tone sweeps.
Reports here are that the included USB mic cable for ARC is about 10 feet long.
"Advanced" mode gives you additional control over the ARC results. I don't know what's offered, but suspect you should plan on using the "Standard" results for now -- even though you may go into "Advanced" to see more info as to what's up with the "Standard" results.
V1.31 on the web site is the latest version. ARC 1.1 (the Windows application) on the web site is also the latest version. I don't have my ARC CD yet, but I suspect the versions on the CD are identical. It is easy enough to check file size and last modified date for what's on the CD compared to what you download.
