ARC X is IK Multimedia’s most advanced room calibration platform, designed to give your monitors professional-level accuracy, tonal control, and virtual monitoring capabilities. Using IK’s VRM™ (Volumetric Response Modeling) technology, ARC X measures your listening space in 1-, 3-, 7-, or 21-point scans (or even a Fast Mode for quicker setups), then applies phase-coherent filtering to correct room resonances and frequency anomalies. Beyond simple correction, ARC X lets you shape the tonal character of your monitoring setup — choose between surgical neutrality or a more musical “voiced” curve. You can also emulate over 20 iconic speaker systems and playback environments (like TV speakers, car stereos, and high-end studio monitors) so you can reference your mix in multiple real-world scenarios, all from the same sweet spot. With real-time monitor control, you can switch between profiles, voicings, and calibration modes easily. ARC X works both as a standalone system (using IK hardware) and as a plugin inside your DAW, giving you flexible integration without taxing your CPU.
