An all-new listening experience

ARC 4 uses a brand-new and more natural analysis and correction algorithm that delivers results you can’t find in other digital room correction systems. By measuring your room across a 3D space around the listening position, IK’s award-winning VRM™ (Volumetric Response Modeling) technology creates a 3D snapshot of your room, identifying problematic issues without over-processing the sound.

You have the choice of going through a 21-point ultra-accurate measurement process or a 7-point quicker one. Both will sound great. The longer measurement is more adequate for fixed installations and permanent setups, while the shorter measurement is ideal for on-the-go or ad-hoc setups, making it possible to measure the room in less than a minute.

The result is an incredibly natural-sounding correction like you’ve never heard. ARC 4 recreates the feeling of working in a properly-tuned room, without sounding “corrected.”

Measure quickly and precisely

Just connect a measurement mic to your interface and launch the step-by-step room analysis software. You’ll be guided through a series of measurements across your listening position, and with ARC’s flexible placement options you can create measurements of multiple monitors and listening positions, so you can virtually adjust the sweet spot for clients or different setups.

Deep control to fine-tune your correction

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 comes with 9 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.

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.
