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.

The Symphony I/O Mk II – Pro Tools HD is designed for the Pro Tools HD user who needs a multi-channel audio interface with the best sound quality at an incredible cost per channel value. Whether using a Mac or PC based studio, Symphony I/O Mk II HD can connect directly to your Pro Tools HDX, Pro Tools HD Native or Pro Tools Core/Accel systems. The Symphony I/O Mk II HD can be utilized alongside or in place of Avid® or Digidesign® interfaces for Pro Tools HD. In fact, each I/O module installed in Symphony I/O Mk II HD appears and functions in Pro Tools HD the same if it were a separate Avid HD I/O interface, so set up is easy and you can take advantage of important Pro Tools features such as sample-accurate delay compensation.

A single Symphony I/O Mk II HD unit can have up to 32 simultaneous analog I/O, so you can have more channels with less rack gear.  Need even more channels?  You can utilize multiple units simultaneously, with one Symphony I/O Mk II HD per every Pro Tools HD port in your system. Calibrating your I/O is easy with Symphony I/O Mk II HD’s front panel touchscreen.

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, 2×6, 8×8, 16×16, or 8×8 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 8×8 or 16×16 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.
