Designed to deliver professional sound quality for audio recording, mixing and mastering, Symphony I/O Mk II is the ultimate music production centerpiece for any modern studio.
Input and Output Flexibility
There is a Symphony I/O Mk II solution for everyone; the home studio, project studio, commercial recording studio and scoring stage. Choose from four base I/O configurations, 2x6, 8x8, 16x16, or 8x8 with 8 mic preamps and easily expand as your studio grows. With two module slots and the capacity for up to 32 inputs and outputs of A/D & D/A conversion per unit, Symphony I/O Mk II offers the best per-channel value of any interface in its category.
Legendary Sound Quality
Apogee engineers have made it their passion to improve every new flagship product by using the latest in electrical components and designing optimized circuitry that often exceeds the expectations of the component manufacturer. This is the Apogee Advantage. Symphony I/O Mk II is the culmination of this 30 year commitment and raises the bar on all Apogee products before it with even better audio clarity and sonic transparency. In fact, when equipped with either the new 8x8 or 16x16 Mk II I/O modules, Symphony I/O Mk II outperforms all other multi-channel audio interfaces available for Pro Tools HD or Thunderbolt based systems, making it the flagship audio interface for the entire professional audio industry and the obvious choice for countless GRAMMY winning artists, producers, songwriters and engineers.
