Notes: Tune your studio to perfection with the world's most effective room correction system - now with a new, highly accurate MEMS measurement mic.

ARC System 2.5 with MEMS microphone is the first acoustic correction system that combines a super accurate MEMS measurement microphone, measurement software AND a correction plug-in to greatly improve the audio monitoring accuracy of speakers in any studio or room listening environment in an elegant, portable, affordable, easy to use and extremely professional solution.

With literally thousands of ARC-based studios worldwide, you can be confident you are making a sound choice!

A new professional MEMS microphone:

ARC System 2.5 now includes a brand new, ultra-precise MEMS measurement microphone that perfectly works in synergy with ARC's correction software (previous ARC mic models will be supported.) The microphone is built around an omnidirectional, high precision MEMS capsule that ensures maximum response accuracy and stability over time.

In contrast to standard condenser measurement microphones, which are potentially subject to subtle frequency response variations over time, MEMS technology is far more stable.

Thanks to the manufacturing process behind them, MEMS microphones boast extreme resistance to humidity and temperature variations as well as increased durability. This means that they are much more forgiving to "professional abuse" and you can carry them around without worrying about damaging them. Also, all microphones units that are manufactured following this procedure, share the same degree of accuracy with near-zero variation in terms of final performance from unit to unit.

As a result, all measurement processes will always be spot on, repeatable and reliable even after longer periods of time.

Did you know? The ARC System 2.5 MEMS microphone makes for a great additional OMNI pattern recording tool you can add to your mic arsenal! Use it to capture the natural ambience of a studio/room while recording vocals, guitars and other acoustic instruments.

Trust your ears:

ARC simply takes your room "out of the mix." Now you can explore your creativity and mix with confidence.

ARC employs Audyssey MultEQ XT32 patented technology to improve your monitoring system ensuring that what you hear is not being affected by problems caused by room acoustics.

Near field monitor systems generally used in studio applications are designed to deliver sound without distortion or coloration; however, when they are placed in a room, the surrounding walls, ceiling, furniture, and other objects reflect and absorb sounds, creating complex artifacts specific to that room that ultimately cause the monitors to lose the accuracy they have been designed for in the first place. As a result, you end up hearing more of the room's sound, than the music being reproduced.

A break-through affordable solution for acoustic room correction:

Traditionally studio acoustics can be improved with acoustic treatments - but these are generally very expensive and require professional installation - which is often not practical in many of today's home and project studios. Other types of electronic correction systems use some form of equalization that works only on the frequency response of the room but worsen the phase response of the audio material. ARC System neatly solves all these problems with a unique and innovative DAW (Digital Audio Workstation,) based solution that works both in the frequency and time domain and is not affected by any of the drawbacks of other types of correction systems.

ARC is designed to provide everything you need to turn any room into a place where serious music production happens. Now you can listen and mix with utmost confidence, knowing that what you hear is what is actually there. All you have to do to is plug the microphone in and follow a few simple steps. No rocket science involved.

Do you really need ARC if your room is already treated?

With ARC you can improve the acoustics of ANY room. An untreated room will experience a dramatic improvement - but also treated rooms will sound MUCH better depending on the quality of the existing treatment. From amateur bedroom studios to the most professional high-end treated rooms, ARC will make an improvement in your monitoring environment.

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
Works with any monitor system in any room
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.
