The Apogee Symphony I/O Mk II Thunderbolt 3 Option Card (SYM2-TB3-CARD) is a powerful upgrade for users seeking the speed, reliability, and ultra-low latency of modern Thunderbolt 3 (USB-C) connectivity. Designed specifically for integration with the Symphony Mk II chassis, this card enables seamless communication with macOS-based DAWs, offering sample rates up to 192 kHz at 24-bit resolution, and making it ideal for high-end recording, mixing, and mastering applications.
This card includes a custom rear panel with dual USB-C ports and can be field-installed into any compatible Symphony Mk II chassis. Whether you're upgrading from older connection formats or outfitting a new build, the SYM2-TB3-CARD gives your Symphony interface the performance benefits of Thunderbolt 3 and 4 environments. Please note that this is a connectivity-only upgrade, it does not include any audio I/O, sync, or MIDI functionality on its own. It's the perfect component for users who already own a chassis and want to unlock next-generation native connectivity.
