The Apogee Symphony I/O Mk II is a multi-channel audio interface featuring Apogee’s newest flagship AD/DA conversion, modular I/O, intuitive touchscreen display and optional world-class microphone preamps. 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 new Symphony I/O Mk II comes with direct connectivity to one of three different platforms - Thunderbolt, Pro Tools HD or Waves SoundGrid network.


All of Symphony I/O Mk II’s essential input and output settings can be accessed from the front panel touchscreen. Change your input selection, monitoring levels, mic pre gain or calibrate your Symphony I/O Mk II to match the levels of the other analog gear in your system.

A high-resolution TFT display delivers all the visual feedback critical for recording and monitoring. Without looking at your computer, Symphony I/O Mk II lets you see metering for up to 64 channels of I/O, 32 IN x 32 OUT - signal levels, polarity, muting, phantom power and Soft Limit.


Symphony I/O Mk II features advanced controls to keep the unit running at an ideal temperature, ensuring the highest level of performance and reliability.
