Anthem Room Correction (ARC™) is a proprietary digital signal processing system that allows you to quickly and accurately optimize the performance of your audio equipment to better suit the unique parameters of your room. By listening to your room’s acoustic signature, ARC can tune your equipment to correct for the performance-robbing effects (reflections, resonances, standing waves, etc.) of the various surfaces and other obstacles in your room. You’ll actually hear the difference ARC makes.

I do not know what the other reviewers are talking about! This app worked like a charm. I was finished in less then 5 minutes. My Martin Logan dynamo600X is only 3 days old so I’m not sure whether the room correction makes an audible difference but as far as ease of use it was smooth as butter.

So disappointed


It’s 2018. Anthem is advertising iOS features on its products while at the same time not ACTUALLY offering apple support. There is no cable provided in the ARC kit that allows you to plug the calibrated microphone into your iOS device as the app instructs you to do. Go ahead and try to use your internal mic and the app crashes every time! “Critical Error” Arc could not complete measuring due to a critical audio problem. This is top of the line equipment! Someone over there is dropping the ball in a major way!

Started to work, never made it through.


App seems to work fine, but while measuring the third listening position, always has an error for me, loses connection to the MRX, and the test time just keeps going until I restart the ARC or shut the unit off.

The Windows desktop app worked fine, but not everyone has a Windows machine/laptop laying around to use.

Still enjoying getting to know the MRX, but this app, as reviewed by others, is a good idea but was worthless to me.
