Ok folks, been using the ARC2 for a bit now, and thought I would post a few things that are good to know for anyone thinking of using it.
1) the ARC is inserted on the master bus, so it has monitor feature which allows you to change the volume, this also effects the levels of your master bus, so sometime I think I am clipping when in fact I wouldn't be if I was not using the ARC2, other time I would be clipping without using it. So I play the song with the ARC off and watch the level meter on the master bus, and turn on the arc and adjust the ARC monitor volume so the volumes are consistent. Took me a few days and a few mixes to figure this out.
2) prior to getting the ARC2, I had the high freq of my KRK Rokit 8s attenuated quite a bit, once I calibrated with ARC2, I noticed the highs seemed distorted during play back. Thought I had issues, After mixdown and listened on another computer, the distortion was not in the mix. I looked at the graph in ARC which shows before/after/target and I noticed in the Before section, I had signifigant hi freq roll off, and ARC corrected it. I think the ARC eq had to add lots of high end to flatten out the room, thus causing a bit of distorion. So I turned up the hi- freq on my monitors re calibrated/ measured and the distortion is now gone during play back.
3) Now that my room has been "corrected" or "corrected" as much as it can, I am thinking I may need to get another set of monitors with smaller woofers, currently I have krk rokit 8s, however they don't quite have the midrange detail, they sound great for the low end. I am not planning to get rid of them, just add a pair of 5" or 6" monitors and have the ability to A/B them, (Anyone have any suggestions for a good 5" or 6" monitor?).
4) You would think that remembering to disable the ARC2 on the master bus, prior to mixdown, would be an easy and minor thing to remember, but I forget almost every time! Drives me crazy!!! LOL!
Just wanted to share, hopefully this information will be helpful. Overall, I am very happy with the ARC2. I has made a positive impact on my mixes
