IK Multimedia ARC Studio Advanced Room Correction System

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.

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 analyzes 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.

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) analog input to analog 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.

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.

Variable resolution and smoothing
Adjust the resolution of the correction filter to use more or fewer frequency bands. Depending on your room's unique sound, this lets you achieve more surgical correction, or a broader, smoother balance.

2 Phase Modes
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.

Includes monitor emulations
ARC Studio can be reloaded instantly with new settings using ARC 4 software, which now features a monitor emulation function. Transform you monitoring 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 now lets you test your mix on different reference systems quickly, without ever having to head to your car or buy additional pairs of monitors!
