IK Multimedia announces the availability of ARC 4, the latest iteration of their advanced room correction system, designed to enhance the accuracy and detail of studio monitoring. The ARC 4 system now includes nine factory-tailored target curves to suit various mixing and listening environments.

Significantly, ARC 4 allows users to define the correction range with adjustable limits for both the high and low frequencies, enabling the preservation of a monitor's characteristic sound or the focus on specific frequency issues. Additionally, the system offers a feature to adjust the resolution of the correction filter, providing the flexibility to apply more granular or broad corrections based on the room's acoustic properties.

Improves Mixing Accuracy

Rooms have a significant impact on how music is heard. The size, shape, materials, and furniture all work to distort the frequency and stereo balance of studio monitors, degrading their sound.

ARC 4's all-new algorithm analyses and corrects these issues in minutes. The music snaps into focus with more controlled low-end, tighter transients and pinpoint stereo imaging. It's like an instant upgrade for monitors, leading their users to mix faster and more confidently than ever.

Installs In Minutes

With the included mic connected to an audio interface, ARC 4 software guides the user through a rapid process of measuring acoustical responses within their listening position. 

IK's award-winning ARC technology uses this 3D snapshot to identify and correct all the problematic issues degrading a monitor's performance.

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

Corrects Any Studio

For pro studios, whether DAW-based or console-based, ARC Studio with ARC 4 offers 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 eliminates the need to insert the ARC 4 plug-in on the master bus of a project and preserves zero-latency monitoring setups. Plus, it allows users to listen to their preferred streaming service with acoustically corrected monitoring without messing around with system drivers.

Using ARC 4, profiles can be created and stored for every configuration, listening position, or monitor pair and quickly recalled or loaded to the processor unit at any time. Whether in a makeshift studio or a world-class one, fine-tuning the monitoring perfectly to taste is no longer a challenge and has never sounded so good. 

Not only is the ARC Studio hardware designed and made in Italy to the highest precision and quality standards, but its clever engineering makes it highly affordable and available at a fraction of the cost of other hardware solutions. Now, everyone can dramatically improve the sound in their mixing environments: from one pair of monitors to multiple monitoring systems to extensive facilities with various mixing and recording rooms.

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 vanishingly low jitter, offering total sonic transparency and accuracy only found in mastering-grade audio converters.

The processor unit connects to the studio and monitors via balanced XLRs with a power-safe relay-based hard bypass - so when bypassed, everything is protected from sudden power-related pops. Between the premium audio quality of ARC Studio and ARC 4's all-new correction algorithm, the result is the most natural, transparent monitoring ever.

Includes Monitor Emulations

ARC Studio can be reloaded instantly with new settings using ARC 4 software. ARC 4 now features a monitor emulation function that turns any monitor system into iconic studio monitors, plus popular hi-fi speakers and mobile devices, with breathtakingly true-to-life results, accurately reproducing the frequency and phase response of the originals.

With over 20 profiles included in ARC 4, a single pair of monitors lets users quickly test a mix of different reference systems without having to head to the car or buy additional monitors.

System Customization

ARC 4 now comes with nine factory-tailored target curves suitable for most situations. The default curve offers optimally balanced results with Flat and other specific curves for 

different needs or setups. By default, ARC corrects the entire frequency spectrum, but users can define limits to upper and lower correction ranges separately. This is useful for preserving monitors' unique voicing or restoring a specific frequency range.

There's also a control to adjust the resolution of the correction filter to use more or fewer frequency bands. Depending on the room's unique sound, this can achieve a more surgical correction or a broader, smoother balance.

Selectable Natural and Linear phase modes ensure precise stereo imaging. Natural mode improves the phase response, while linear phase maintains the original inter-channel phase response, which may be preferable in certain rooms and conditions. With ARC Studio, users will experience limitless flexibility as their studios grow and evolve.

Pricing and Availability

ARC Studio package, aimed at providing a comprehensive solution for studio acoustics correction, includes a processor unit, the ARC 4 software, and a measurement microphone, priced at $/€299.99. For existing users of any ARC version with a microphone, iLoud MTM, or iLoud Precision, an upgrade option is available for $/€249.99, which includes the processor unit and ARC 4 software, excluding the measurement mic. Additionally, a standalone package of the ARC 4 software with a measurement mic is offered at $/€199.99, and the software alone can be purchased for $/€149.99.
