IK Multimedia ARC System 2 Advanced Room Correction System


ARC System 2 (Advanced Room Correction) is the sequel to the first and only acoustic correction system that combines a measurement microphone, measurement software AND a correction plug-in to improve the listening accuracy in your mixing room or project studio. It's an elegant, low-cost, portable solution for scenarios (such as home studios) where you may not be able to apply all the recommended acoustic treatments.

ARC uses Audyssey MultEQ® XT32 patented technology to improve your monitoring system by intelligently correcting for poor room acoustics. Near field monitor systems used in studio applications are designed to deliver sound without distortion or coloration. However when they are placed in a room, the sound you hear from the speakers is heavily influenced by the acoustics of that room. This ultimately causes your speakers to lose the accuracy they were been designed for.

Some electronic correction systems use forms of equalization that work only on the frequency response of the sound you hear, while simultaneously making the phase response worse. ARC System 2 solves this problem with a unique DAW-based solution that works in both the frequency and time domain.

ARC 2 can improve the listening experience in any room. An untreated room will experience a dramatic improvement – but treated rooms will also sound better, depending on the quality of the existing treatment.

Product Description

With ARC you can electronically correct for your room’s acoustics in 2 easy steps. First you measure your room response in specified placed using the included calibrated measurement microphone and software. ARC 2 allows you to take from 7 to 16 different measurements, depending upon the room size and your desired level of correction.

These measurements give the ARC 2 plug-in software the information it needs to accurately apply the correction. Once measurements are taken, ARC 2 automatically calculates a correction algorithm that you can apply to your music with the included plug-in, placing it on your DAW master BUS. Using ARC 2 you can mix with greater confidence, knowing that your music will translate better to the outside world.

ARC 2 includes a calibrated, omnidirectional measurement microphone that provides a transparent, colorless, highly-linear characteristic.
