Universal Audio Apollo x16D|Flagship Dante Rackmount Interface
Flagship conversion and immersive monitoring for pro studios

The Universal Audio Apollo x16D is a rackmount Thunderbolt audio interface built by Universal Audio for Dante networked audio and immersive monitoring, offering 16 x 16 Dante I/O (AES67 @48 kHz), flagship elite-class Apollo X Gen 2 D/A monitor conversion, 24-bit / 192 kHz resolution and 133 dB dynamic range, with HEXA Core DSP mixing at near-zero latency.
Unlike a typical interface, the Apollo x16D focuses on reference conversion and precise monitoring — serving consoles, outboard and immersive production so your final mixes and masters translate anywhere.
