Ultimate sound quality meets the most popular audio-over-IP network.

Symphony I/O Mk II is a multi-channel audio interface featuring Apogee’s flagship AD/DA
conversion, modular, configurable I/O (up to 32 inputs and outputs), 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.

And now, with the Symphony I/O Mk II Dante

option card and a simple ethernet cable, Symphony I/O Mk II can be easily connected and
shared across post production, broadcast, live sound or recording studio networks, unleashing
legendary sound quality on the world’s most popular audio-over-IP solution. The Symphony I/O
Mk II Dante option card also includes Pro Tools HD connectivity for integration of Pro Tools HD
systems into a Dante network environment. No other Dante-enabled audio interface offers this
level of quality, flexibility and modularity.

Modular and Configurable
The Symphony I/O Mk II Dante option card uses Audinate’s Brooklyn II module which features
plug-and-play media networking for up to 32 bidirectional channels at 96kHz and 16
bidirectional channels up to 192k. The system can be configured with a number of custom

channels with ProTools and redundant Dante connectivity to be fitted into a single two space
rack device providing the smallest footprint available with this feature set.
