Calibration for speakers and headphones

The Apollo Monitor Correction add-on integrates precise speaker and headphone calibration directly into Universal Audio's Apollo X Gen 1 and Gen 2 audio interfaces. It supports a variety of audio setups, from stereo to extensive 9.1.6 multi-channel configurations, and provides calibration for over 500 headphone models. Multiple outputs can be calibrated simultaneously, including one speaker profile and up to two headphone profiles, depending on the Apollo X model used.

The add-on enables virtually latency-free performance and includes calibrated bass management for stereo speaker systems with subwoofers. It supports various target modes such as Flat, the Dolby Atmos Music curve, user-defined targets and various device simulations via Translation Check. It can be used on up to three devices simultaneously and requires a robust internet connection.

Compatibility exists with macOS and Windows operating systems as well as with the UAD Console v1.2.1 and UAD-2 software v11.5.1 or newer.
