Core benefits

Automated room correction
Detect and eliminate room coloration with meticulous precision. ARC X measures your space and applies intelligent, phase-coherent corrections for a professional-grade monitoring experience.

Advanced tuning flexibility
Shape your tonal balance to match your personal taste or creative goals. Whether you prefer surgical neutrality or enhanced musicality, ARC X adapts to your needs.

Voicing emulation
Experience the sound of iconic studio monitors and real-world playback systems instantly. ARC X allows you to reference your mix across industry standards — all from a single sweet spot.

Real-time monitor control
Easily switch between profiles, voicings, and calibration modes with intuitive, hands-on control.

On-speaker operation
ARC X delivers latency-free correction directly on supported devices, bringing studio-wide optimization without taxing your CPU.

Third-party support
Use ARC X on non-IK monitors with ARC Studio hardware or the ARC X plug-in for a fully optimized system.

Calibration: Trust what you hear
Every surface in your room — walls, ceilings, furniture — colors your sound, introducing subtle distortions and misleading resonances that sabotage your mix. ARC X puts an end to that guesswork.

Through high-resolution acoustic measurement and advanced frequency domain correction, ARC X creates a custom-tailored response profile that reveals your audio truthfully and naturally.

The result? A pristine monitoring environment that lets you trust every detail — so you can work faster, and create mixes that translate with stunning accuracy.

What makes ARC X different
ARC X combines over a decade of research and development into a seamless solution. From real-time calibration to high-end reference emulation and deep tuning flexibility, every detail is engineered to elevate your workflow and unlock your full creative potential.

Measure quickly and precisely
Connect the included measurement mic to your interface and follow the guided step-by-step analysis. ARC X captures a 3D snapshot of your room’s acoustic response using IK’s award-winning VRM™ (Volumetric Response Modeling) technology. Choose between a 1-, 3-, or 7-point quick measurement for fast setups or a 21-point ultra-precise scan for fixed installations.

Auto correction for a perfectly balanced sound
ARC X automatically analyzes data and creates a correction profile tailored to your space. The advanced algorithm resolves frequency and phase inconsistencies without overprocessing, providing a seamless experience akin to working in a professionally tuned room.

Fine-tune to match your preferences
Go beyond room correction with target curves, voicing emulation, and custom adjustments. Whether you prefer a perfectly flat response or a specific tonal character, ARC X gives you the flexibility to fine-tune your ideal listening environment.

ARC X in action
ARC X features an intuitive interface that streamlines room analysis, calibration, and speaker management. Users can visually monitor adjustments, compare tuning profiles, and fine-tune their system with just a few clicks.

Target curves
Choose from 9 expertly designed target curves to suit various monitoring needs. Whether you want a balanced flat response or specific tonal shaping, ARC X adjusts to your workflow.

Advanced correction algorithms
Achieve a natural and precise sound with advanced time and frequency domain correction. ARC X guarantees optimal left-right phase coherence with selectable Natural and Linear phase modes.

Flexible correction options
Adjust the low and high correction ranges to keep your monitors' original voicing. ARC X allows you to fully control how much correction is applied.

Variable resolution and smoothing
Fine-tune the correction filter’s resolution to match your room’s acoustics. Adjust between precise, surgical correction or a broader, more natural balance.

Virtual monitoring

Iconic speaker emulation
ARC X can precisely replicate the frequency and phase response of over 20 industry-standard reference monitors and playback systems. Quickly assess your mix on different speakers, from high-end studio monitors to consumer devices, without leaving the optimal listening position.

The ARC virtual monitoring application works in conjunction with the correction settings to deliver the best sound possible in any listening environment, making it easy to test a mix across various reference systems quickly while saving money on unnecessary secondary monitors.

ARC X plug-in for DAW-based workflows
For those who own iLoud Micro Monitors or studio monitors from other brands, or prefer to keep calibration within the DAW, the ARC X plug-in provides the same high-quality correction as the hardware system, designed for in-the-box production workflows.

Ideal for producers and engineers working entirely in the box, the plug-in provides precise monitoring correction directly on your master bus, with no hassle and full control.

It also features advanced metering tools powered by T-RackS technology, including Peak, RMS, LUFS, and Dynamic Range, to help you visualize your mix and ensure compliance with today’s loudness standards.

Integration across the iLoud Ecosystem
ARC X is designed to work seamlessly with a range of IK Multimedia monitoring solutions, making it the centerpiece of an expandable, future-proof monitoring system.
