The Universal Audio Apollo 16 MkI is a professional rackmount audio interface designed for studios needing high-channel analog I/O and premium sound quality. Featuring 16×16 line-level analog I/O via DB-25 connectors, UAD-2 Quad Core DSP, and world-class AD/DA conversion, it allows real-time tracking with classic analog-modeling plug-ins and ultra-low latency. Ideal for studios with existing mic pres and outboard gear, the Apollo 16 MkI supports up to 64×64 I/O via Thunderbolt when daisy-chained with other Apollos, making it a powerful hub for hybrid analog-digital workflows.
