Universal Audio Apollo x16 Gen2｜Flagship 16x16 Thunderbolt Audio Interface with Elite Conversion & Real-Time UAD Processing
The Apollo x16 Gen 2 is Universal Audio’s flagship Thunderbolt audio interface, designed for professional recording, mixing, and post-production. It combines 16x16 analog line I/O, 24-bit/192 kHz high-resolution AD/DA conversion, and UAD-2 HEXA Core real-time DSP power, enabling near-zero latency recording and mixing with UAD plug-ins. Featuring Dual-Crystal clocking for ultra-low jitter and optional Sonarworks® Monitor Correction integration, the Apollo x16 supports immersive formats up to 9.1.6 — making it ideal for Dolby Atmos, Auro-3D, and Sony 360 Reality Audio workflows.
