The Universal Audio Apollo x6 (2019/1st Generation X Series) is a 16x22 Thunderbolt 3 audio interface designed for Mac and Windows, catering to producers and project studios requiring high-end A/D and D/A conversion without needing numerous analog preamps. Released as part of the Apollo X lineup (premiered late 2018/early 2019), it focuses on elite-class audio, real-time UAD processing, and surround sound capabilities.
