Correct Your Room and Get Better Mixes

Even if you use top-shelf nearfield monitors, when they interact with your control room's walls, ceiling, and furniture, distortion and coloration occur, creating a poor acoustical environment. Bad acoustics can wreak havoc on your mixes. But there's a solution: use IK Multimedia's ARC System 2.5 to optimize the sound of your room. ARC employs Audyssey MultiEQ XT32 technology to improve your monitoring system, effectively taking your room out of the equation. ARC System 2.5 comes with everything you need to get the job done, including an ultra-precise MEMS microphone. Whether you've already acoustically treated your mixing room or not, ARC System 2.5 will help you mix more accurately.

It's easy to integrate ARC System 2.5 into your studio

The ARC (Advanced Room Correction) system measures and calculates the acoustics in your room, then applies correction via an advanced EQ plug-in. Using the included MEMS microphone, ARC System 2.5 software measures your room's acoustics and formulates corrections. The system then uses a frequency/time-correction processing plug-in to work with your DAW, giving you a "corrected" environment every time. If you want the most accurate, optimum room for mixing, use ARC to make it happen.

Ideal for any control room

Ever since you started mixing audio, you've been chasing "perfect" acoustics, right? ARC System 2.5 has the potential to make any room sound more accurate. Think of it this way: if you have no acoustic treatment, you'll encounter all manner of acoustic anomalies like null points, standing waves, asymmetrical reflections, and so on. ARC System 2.5's advanced processing can work wonders in a room like that, and you'll immediately notice a clearer stereo image, more accurate frequency response, and better separation between sounds. Now consider a well-treated room: ARC System 2.5 has the high resolution to iron out any tiny inconsistencies it can find, still leading to a more accurate mixing environment. At Sweetwater, we've also found ARC System 2.5 to be a great solution for traveling engineers and on-the-spot corrections.

Includes a professional MEMS mic

ARC System 2.5 includes a high-precision MEMS measurement mic. This omnidirectional microphone is tailor-made for ARC's correction software, so it provides optimal results that are both reliable and repeatable. And unlike standard condenser mics, MEMS technology is immune to subtle frequency response changes over time. This microphone is extremely durable and resistant to humidity and temperature variations, so it will continue to serve you well for years to come.
