IK Multimedia ARC Studio+ is a hardware room correction processor with built-in subwoofer management. It sits between your interface or monitor controller and any studio monitors, measures the room with the included ARC microphone, and corrects the full 20 Hz to 20 kHz range inside the box. It calibrates standalone from the front panel with no computer, converts at 32-bit up to 192 kHz with 120 dB(A) dynamic range, adds USB-C and optical S/PDIF digital I/O, and runs at 1.4 ms latency in Natural Phase mode.
Room correction and sub alignment in one box, calibrated with one button.
Correction runs in dedicated hardware, not in a plug-in, so it applies to everything that reaches your monitors: the DAW, a reference track in a browser, a client's phone, a hardware synth. There is nothing to bypass before a bounce and no load on your computer or DAW.
Calibration starts at the front panel. Plug the ARC microphone into the dedicated ARC MIC input and run a 1-point or 3-point measurement with no computer, DAW or interface involved. For more resolution, connect ARC X for 7-point and 21-point 3D room measurement, target curve editing and profile management, then upload the profile and close the software. The correction keeps running in the hardware.
A dedicated balanced subwoofer output handles 2.1 systems. During calibration ARC Studio+ detects the sub and aligns gain, crossover, phase and delay with the mains automatically, with any brand of monitors and any subwoofer. Three Scene buttons on the front panel each store a complete setup, including calibration profile, speaker routing, sub on or off and input selection, and a relay hard bypass keeps the bypassed signal path electrically isolated from the processor.

How Is ARC Studio+ Different From the Original ARC Studio?
ARC Studio+ adds a dedicated ARC MIC input so calibration runs from the hardware without a computer, a subwoofer output with automatic sub alignment, USB-C digital audio input, optical S/PDIF input and output, three recallable Scenes and a relay hard bypass. The original ARC Studio stays in IK's range as the stereo, analog-only option.
Does ARC Studio+ Work With a Subwoofer?
Yes. Connect the sub to the dedicated balanced output and it is detected during calibration. Gain, crossover, phase and delay between the sub and the mains are set automatically, so a 2.1 system is aligned without separate processors or manual measurement.
Do I Need a Computer to Use ARC Studio+?
No. Calibration, correction and Scene recall all run from the hardware. A computer is only needed if you want ARC X for higher resolution multi-point measurement, target curves or virtual monitor profiles, and once the profile is uploaded the computer can be disconnected.
Who Is ARC Studio+ For?
Home and project studios, mix and mastering rooms, post production suites and any room where the acoustics are fighting the speakers. It is also the straightforward way to add a subwoofer to an existing pair of monitors and have it set up correctly, and the digital I/O lets it sit in analog, digital or hybrid monitoring chains.
How Much I/O Does ARC Studio+ Have?
Two balanced combo XLR/TRS inputs, two balanced XLR monitor outputs, one balanced TRS subwoofer output, a dedicated XLR measurement microphone input, USB-C for digital audio and control, and optical S/PDIF in and out.
What Comes in the Box?
The ARC Studio+ processor, the ARC measurement microphone with clamp and pouch, a USB cable and the power supply unit. ARC X software is included and is downloaded after product registration.
