Measurement Microphones

Notes: Make any studio monitors sound better

High-definition monitoring for all

Upgrade any studio monitors instantly with the first out-of-the-box acoustic room correction system that anyone can afford. ARC Studio combines a standalone correction processor, new ARC 4 measurement software and a room analysis microphone.

There's a reason all today's top-tier studio monitors are adding active room correction - it supercharges their performance and ensures mixes translate flawlessly. ARC Studio offers this same massive boost in performance and accuracy to any monitor in every studio.

For the first time in the recording industry, an affordable hardware processor can be used as a correction and calibration system for any type of studio - be it home, project or professional - without the limitations of a software-only system.

Standalone digital acoustic correction system
Dramatically improves your mixing accuracy

Installs in minutes in any studio or space
Sonically invisible, audiophile performance
Emulates top monitors and playback systems
Customize your monitors' performance to taste

Improves mixing accuracy

Your room has a big impact on how you hear your music. The size, shape, materials and furniture all work to distort the frequency and stereo balance of your monitors, degrading your sound.

ARC 4's all-new algorithm analyses and corrects these issues in minutes. Your music snaps into focus, with more controlled low-end, tighter transients and pinpoint stereo imaging. It's like an instant upgrade to your monitors.

And when you trust what you hear, you'll mix faster and more confidently than ever.

Installs in minutes

Plug the mic into your interface and you'll be guided through measuring acoustical spots within your listening position. IK's award-winning ARC technology uses this 3D snapshot to identify and completely correct all the problematic issues degrading your monitors' performance.

An all-new listening experience

ARC 4 stores the correction profile and loads it into the ARC Studio processor, sitting invisibly between your interface and monitors to apply to all incoming signals. The standalone processor corrects studio monitors in any studio, including hardware- and console-based setups.

Audiophile performance

ARC Studio features a 120 dB(A) analogue input to analogue output dynamic range, 0.5 Hz to 40 kHz frequency response and ultra-stable clocking for vanishing low jitter, offering total sonic transparency and a level of accuracy you only find in mastering-grade audio converters.

And it connects to your studio and monitors via balanced XLRs with power-safe relay-based hard bypass - so when bypassed you're protected from sudden power-related pops. Between the premium audio quality and ARC Studio's all-new correction algorithm, you'll enjoy the most natural, transparent monitoring ever.

Affordably priced

ARC Studio hardware is not only designed and made in Italy to the highest precision and quality standards, but its clever engineering makes it available at a fraction of the cost of other hardware solutions.

Now everyone can dramatically improve the sound in their mixing environments: from a single pair of monitors to multiple monitoring systems, up to large facilities with multiple mixing and recording rooms.

Improves any studio

For pro studios, whether in-the-box or console-based, ARC Studio allows for a sonically transparent correction and custom-tuning for any monitoring setup from nearfields to mains, preserving the inherent system's sonic quality.

For DAW-based studios, ARC Studio frees you from the hassle of inserting plug-ins on the master bus of your work and preserves zero-latency monitoring setups, plus it allows you to listen to your preferred streaming service with acoustically corrected monitoring without messing around with system drivers.

You can create a profile for every configuration, listening position or even monitor pair. Whether you're in a makeshift studio or a world-class one, fine-tuning your monitoring to your taste has never been easier and has never sounded so good.

Customise your monitors

Customise your setup for ideal performance no matter your preference. ARC 4 offers deep control over each profile so it always sounds its best:

Target curves

ARC 4 now comes with 9 factory target curves for most situations. The default curve offers optimally balanced results with other specific curves for different needs or setups.

Adjustable correction range

By default, ARC corrects the entire frequency spectrum, but you can define limits to both upper and lower correction ranges separately. This is useful if you want to preserve the unique voicing of your monitors or are just looking to correct a certain frequency range.
