About Apogee Electronics Symphony I/O MkII 8x8 MP

After years of industry-leading innovation, the Symphony I/O Mk II 8x8 MP Connect Series Pro Tools HD Audio Interface is the epitome of superior sound quality and intuitive control. This state-of-the-art audio interface is equipped with a front panel touchscreen, providing easy access to all essential input and output settings.

The Symphony I/O Mk II is designed with advanced temperature controls to ensure optimal performance and reliability. The unit's improved fan and chassis ventilation design allow for quiet and efficient component cooling. These temperature controls can be easily accessed from the touchscreen and control software.

The Symphony Control software for macOS provides comprehensive access to all features and functions of the Symphony I/O Mk II Thunderbolt. From setting gain levels to managing routing, controlling output levels, setting calibration, and setting up multiple mixers, this software has got you covered.

The unit also features an audiophile-grade headphone amplifier with Apogee's Constant Current Drive technology, providing massive power while maintaining extremely low distortion and linear frequency response.

Designed for the Pro Tools HD user, the Symphony I/O Mk II HD offers a multi-channel audio interface with superior sound quality at an incredible cost per channel value.
