Professional audio calibration reaches new heights with the Sonarworks SoundID Reference Multichannel Edition bundle, featuring the XREF20 Mic and Apollo Monitor Correction for comprehensive stereo to multichannel system calibration up to 9.1.6 channels. This complete package combines SoundID Reference for Multichannel and Headphones with the Apollo Monitor Correction Add-on, creating seamless integration with Universal Audio’s Apollo X hardware for studio-grade precision.
SoundID Reference provides pre-calibrated profiles for over 500 headphone models alongside accurate speaker measurement and calibration capabilities for complex multichannel configurations. The software includes essential DSP processing controls such as Mono, Dry/Wet, and Safe Headroom functions, plus three distinct filter modes: Zero Latency, Mixed, and Linear Phase. Music creators worldwide rely on the Flat target curve as their industry-standard reference, while Custom Target adjustments and Translation Check functionality allow real-time curve modifications and device simulations.
The Apollo Monitor Correction Add-on brings integrated calibration directly to Apollo X hardware, enabling simultaneous calibration of one speaker profile and up to two headphone profiles with near-zero latency performance. Supported target modes include Flat, Dolby Atmos Music curve, Custom Target options, and device emulation through Translation Check, ensuring optimal audio performance across any professional environment.
