Effective Mix Insurance for Your Studio

Get to know them!

Even with proper acoustic treatment, it's difficult to optimally tune a room that wasn't purpose-built to be a studio. That's why so many engineers have turned to IK Multimedia's ARC. This revolutionary room correction system leverages an ultra-accurate measurement microphone, analysis software, and a correction plug-in to ensure that everything that comes out of your speakers is something you can trust. For ARC 4, IK developed a faster, easier calibration process, in addition to a more natural-sounding correction algorithm for even better results than before. Expanded virtual monitoring equips you with more than 20 iconic studio monitor profiles. You also get an updated interface with dark and light modes, along with the ability to manage and switch profiles within the ARC Studio software. Want mixes that translate? With ARC 4 in your bag of tricks, your music will sound great everywhere.

All-new, natural-sounding correction algorithm

ARC software has always sounded great, but ARC 4 takes it to a whole new level. Its new correction algorithm offers an improved, more natural-sounding result that's guaranteed to make a difference in your mixes. The secret behind this algorithm is IK's amazing VRM (Volumetric Response Modeling). This technology creates a three-dimensional snapshot of your room, identifies problem frequencies, and then fixes them without overprocessing your sound. Whether you use ARC 4's ultra-accurate 21-point measurement process or the new, faster 7-point one, you'll benefit from the sound of a properly tuned room with zero unwanted sonic artifacts.

Room correction made easy

To deploy IK Multimedia's ARC 4, you set up the included IK Multimedia MEMS measurement microphone, activate the room correction process, and generate a room correction profile. Once you've got the profile, you instantiate the ARC 4 plug-in on your mix's master bus. ARC 4's advanced processing will then leverage the data in your correction profile to compensate for your room's acoustic deficiencies. Here at Sweetwater, we've found that ARC 4 enables us to hear exactly what was recorded, which helps us make more informed mixing decisions, no matter what type of environment we're mixing in.

Over 20 studio monitor emulations

ARC 4 arrives with over 20 emulations of world-famous studio monitors. The software re-creates the frequency and phase response of these monitors perfectly, enabling you to test your mixes on a variety of different reference systems, all from one single location. You can also use ARC 4's virtual monitoring feature to emulate real-world devices like televisions and car stereos. Achieving perfect mix translation has never been easier!

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
