True Thunderbolt Performance

Lowest Latency. Superior Sound Quality.

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.

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.

* Logic Pro X at 96kHz / 32 buffer setting

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 write data 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 listening experience.
