Symphony I/O Mk II Thunderbolt

Multi-channel Thunderbolt 2 Audio Interface for Mac

Symphony I/O Mk II Thunderbolt is the most powerful multi-channel audio interface for Thunderbolt-based Mac workstations. Designed for the home or professional studio running Logic Pro X or any other native based DAW, this system offers your choice of 4 different base I/O configurations with the option to expand up to 32×32 simultaneous channels per unit while still maintaining incredibly low latency.

True Thunderbolt Performance

Symphony I/O Mk II Thunderbolt delivers the full potential of Thunderbolt 2 performance with the lowest latency, unmatched CPU efficiency and 2 ports for connecting additional peripherals.

Low Latency

Symphony I/O Mk II Thunderbolt relies on Apogee’s proprietary Thunderbolt driver, written from the ground up to offer unmatched performance and efficiency. When using Logic Pro X, latency has been reduced to an astounding 1.35 ms round-trip*, allowing you to monitor through your DAW, plug-ins included, simplifying your workflow and leveraging the power of your Mac. Even when your session’s DSP demands require a higher buffer setting, Symphony I/O’s ultra-low latency means no longer having to choose between power and speed.

To accommodate different workflow preferences, Symphony I/O Mk II Thunderbolt features optional direct hardware monitoring through Symphony Control Software with 0.6ms of latency.

Devours Bits, Sips CPU

Symphony I/O Mk II Thunderbolt’s custom driver includes a revolutionary Direct Memory Access (DMA) engine to more efficiently read and ta directly to Mac memory independent of the Mac CPU.

The DMA engine, running on Symphony I/O Mk II Thunderbolt’s hardware logic chip, increases the driver’s efficiency and provides the highest resolution signal possible to the DAC stage. This implementation allows the driver to crunch an enormous amount of data at an amazing speed, while making a very light demand on your Mac CPU. You benefit with lower latency, more plug-in power, and a transparent and encompassing

A new control experience

Symphony Control has been built from the ground up and replaces Apogee’s Maestro software for Symphony I/O Mk II users. Symphony Control delivers all the functionality of Maestro in a new, highly customizable user interface along with innovative new features like Talkback functionality, the simplified “Essentials” control window and an FX Send mixer feature, recently introduced as part of the Element Control software.
Symphony Control also features compatibility with the new Apogee Control hardware remote.
