Universal Audio Apollo x16D Gen 2 | Dante-Integrated Flagship 16×16 Audio Interface
Apollo x16D Gen 2 combines 16×16 analog line I/O, UAD-2 HEXA realtime processing, and Dante® networking, and features Apollo X Gen 2 flagship A/D and D/A conversion for 24-bit/192 kHz fidelity with professional clocking. Whether in the studio, on stage, or across multi-room networked setups, x16D lets you run UAD plug-ins at low latency, bringing classic analog tone to any production. With both Thunderbolt and Dante, you can flexibly link multiple Apollo units, and use Apollo Monitor Correction powered by Sonarworks® to calibrate monitoring from stereo to immersive formats.
