IK Multimedia ARC System 4 Upgrade | Professional Monitor Room Correction Software Upgrade
ARC System 4 Upgrade (Software Only) is an upgrade license for advanced producers that reduces the acoustic impact of a room through measurement and automatic compensation technology, making mixes more translatable and consistent. This is a software upgrade and does not include any physical microphone or hardware.
Key Product Features
- Guided measurement workflow, supports multiple measurement points to match the actual listening area
- Advanced frequency and phase compensation to improve low-frequency buildup, comb filtering, and room resonances
- Allows multiple calibration presets for quick switching between different speakers, seats, or target curves
- Provides neutral or customizable target curves, balancing accurate monitoring with stylistic reference
- Low-latency monitoring mode, suitable for recording, overdubbing, and live performance
- Preset and snapshot management for easy backup, cross-project use, and switching between scenarios
- Supports loading calibration files for common omnidirectional measurement microphones (depending on user's existing equipment)
- Designed to be used at the end of the monitoring chain to avoid "printing" the correction into exported audio files
- Upgrade (Software Only) license: provides upgrades for existing users; does not include microphone or hardware
System Requirements
- Operating System: 64-bit Windows and macOS (recent versions recommended)
- CPU & RAM: Modern multi-core CPU; 4 GB RAM or more recommended
- Storage: A few hundred MB of available space required for installation and measurement data
- Display: Recommended 1280 × 768 or higher resolution
- Audio Interface: Capable of stable output to the monitoring system and supports the microphone/preamp required for measurements
- Sample Rates: Compatible with common sample rates (e.g., 44.1–96 kHz, depending on project settings)
- Network: Internet connection required for installation, license activation, and updates
- Measurement Microphone: An omnidirectional measurement microphone is recommended; this product is a software upgrade and does not include a microphone
- Upgrade Eligibility: A valid existing license that can be recognized is required; details are subject to the manufacturer's upgrade policy
Plugin Formats
- AAX
- AU
- VST3
Supported Applications and Integration into Main Workflow
As a monitoring correction plugin, it is suitable for mainstream DAWs that support AAX/AU/VST3. It is recommended to place the plugin at the end of the monitoring chain or on the master/control bus (for example, some software provides a Control Room, Listen Bus, or Monitor FX) to ensure it only affects listening and not the actual exported audio files. You can disable the plugin when exporting or bouncing, or use the DAW's monitoring path to prevent the correction from being printed to files; you can also create multiple calibration presets for different speaker sets and work scenarios for quick switching and comparison.
