How ARC System works

1) The first step is to measure your room

To do this you can simply connect the included professional measurement microphone to any phantom powered MIC input in your audio interface and launch the included ARC System measurement software for Mac/PC. Then the software will guide you through 5 easy steps that will allow you to properly set up the microphone and measure your room. Thanks to Audyssey MultEQ® technology (and uniquely compared to other room correction EQ systems of advanced self-calibrating monitors), ARC System not only allows you to measure and correct the sweet-spot, (where normally, the mixing engineer is seated), but you can also measure multiple positions in the room ensuring the most accurate representation of its acoustical problems in the overall space. This way you will be able to correct the sweet-spot, as well as other various listening positions with-in the room.

In fact, instead of applying a regular standard EQ as all other systems do (that will be “valid” only in the sweet-spot, making all other room areas sound worse than before) the ARC system will analyze all zones you have in your studio, such as your center sweet-spot, producer desk or client couch. It will then provide a general correction that will effectively work on all of the zones, at the same time. If you want to get more detailed, you can measure multiple areas of the room (engineer’s area, client sofa, etc.) separately, and, using the menus in the plug-in, quickly and easily change the “sweet spot” of the room. Once the measurements have been taken, the measurement software will save those results as files that describe the room acoustics and the relative corrections. If you have various speakers in your studio, you can take multiple measurements and simply repeat the process, then save it in different files. The overall measurement process will take only a few minutes, even with the maximum number of measurements possible.

2) The second step is to apply the correction as a plug-in in your preferred DAW

The second step is to apply the correction as a plug-in in your preferred DAW. To do this, simply open your DAW and conveniently apply the ARC System plug-in on the master BUS of your DAW (such as Pro Tools®, Cubase™, Logic™, Sonar™, Live™, etc.), turn the correction on, and voila’: the distortion introduced by your room acoustics will be corrected, allowing you to finally trust the sound of your monitors and your studio. Now, you will be able to select the various measurements you have made from the plug-in interface, easily.

The below screen-shot detail of the ARC System plug-in shows how a highly distorted monitoring system is flattened almost perfectly when MultEQ® is applied. In Orange is the actual room response, in Green is the flat-response of an ideal speakers/room system and in White is the corrected room response applied by ARC system. As you can see the low frequency extension of the speaker is not pushed beyond the physical limits of the speaker, another advantage in comparison to all conventional room correction EQ (“auto” equalizers).
