Have you ever mixed a song that sounded awesome in your studio, but then you heard it played on another system in another room and thought, “What happened?” Studio engineers have been there before and know all too well the sheer dismay such experiences cause. Thankfully, IK Multimedia is here to make these panic-inducing moments a thing of the past with the ARC Studio Advanced Room Correction System. This comprehensive setup combines a measurement mic, software, and an external hardware processor to create a simple, highly effective acoustic correction solution. Simply take room measurements with the mic and software, send the correction filters to the external hardware processor via USB, and prepare for mixes that sound great everywhere.
The IK Multimedia ARC ON·EAR is a portable, standalone DAC and headphone amplifier built to correct your headphones’ frequency response and emulate the experience of mixing on a professional control room. It lets you load up to 5 custom calibration profiles, chosen from a database of over 250 headphone models, so you can mix with confidence no matter which cans you're using. At its core is a 32-bit ESS Sabre converter and ultra-low distortion output stage, delivering clear, high-resolution sound. The device supports digital input via USB-C and analog input via 3.5 mm jack, while output is on a 6.3 mm headphone connection. It’s powered by a rechargeable lithium battery for up to 4 hours of use, making it ideal for mobile workflows. Controls on the unit include preset selection, monitor-model toggling, a function button (for dim/mute/A-B), and a large analog volume dial. With the included control software, you can use 3-band EQ, crossfeed, and virtual speakers to simulate different listening environments — from studio monitors to smartphone speakers. Key Features Standalone 32-bit DAC + headphone amplifier with built-in room-correction DSP Supports USB-C (digital) and 3.5 mm analog inputs 6.3 mm high-power headphone out (200 mW) Onboard correction for 250+ headphone models via loadable profiles Save up to 5 user-adjustable presets 3-band EQ, crossfeed, and virtual monitoring (virtual speakers) Large analog volume knob with digitally controlled precision Function (FN) button for A/B, mute, or dim Built-in lithium battery with ~4 hour runtime Compact, rugged aluminum chassis + protective case
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. Key Features Automated room measurement with 1-, 3-, 7-, or 21-point scans Built on VRM™ technology to model 3D acoustic space Real-time room correction with phase-coherent filters Advanced tuning: set target curves, adjust low/high range, change filter resolution Nine built-in target curves + user-defined curves Natural and Linear phase modes Virtual speaker emulation (20+ models) & immersive monitoring Real-time monitor control panel: switch calibration, profiles, and voicings Available as both software (plugin) and integrated on selected IK hardware
