limited edition audio interface

Few audio interfaces generate the level of excitement among professional engineers as Apogee’s latest release, the Symphony I/O MkII Anniversary Edition, which combines cutting-edge technology with extraordinary exclusivity.

Limited to just 100 units worldwide, this special edition celebrates nearly a decade since the original MkII’s debut and features a distinctive purple finish that pays homage to Apogee’s heritage. Each unit comes personally signed by company co-founder Betty Bennett and renowned mixing engineer Bob Clearmountain, along with a limited Apogee History Book that chronicles the company’s influential journey.

The Anniversary Edition marks a significant technical milestone as the first Symphony I/O MkII to incorporate Thunderbolt 3 connectivity for Mac systems. This advancement enables ultra-low latency performance—achieving an impressive 1.35 ms round-trip when used with Logic Pro X—while minimizing CPU usage for peak system performance. The custom build options allow users to configure the system with various modules to perfectly match their studio requirements. The product is scheduled to be available from October 2025 with a starting price of £6999 RRP inc VAT.

For professional studios managing complex workflows, this combination of speed and stability has proven invaluable. This premium interface represents the pinnacle of home studio equipment for serious producers seeking professional-grade recording capability without booking external facilities.

At the heart of the interface are the latest Special Edition I/O modules featuring ESS 9822Pro A/D converters and ultra-low-distortion analog output drivers.

These components establish new benchmarks for clarity and transparency, delivering a noticeable improvement over previous iterations. The interface offers exceptional capacity for sound design experimentation, allowing users to create complex layers and textures with pristine audio quality. The system’s modular architecture accommodates configurations ranging from 2×6 to 32×32 inputs and outputs, with backward compatibility for legacy Symphony I/O systems.

The interface’s intuitive touchscreen display provides immediate access to critical functions, complemented by detailed software control via Apogee Control 2.

For immersive audio projects, the system simplifies monitoring setups for formats like Dolby Atmos and Sony 360 Reality Audio with support for up to 32 speaker outputs.

Built for professional durability with a rugged, serviceable construction, the Anniversary Edition comes with an exclusive extended three-year warranty.

The quiet operation—with fans activating only during high-temperature conditions—and future-proof design via modular expansion slots have made this limited release a coveted acquisition for top studios and engineers worldwide, many of whom rely on Apogee’s conversion technology for GRAMMY and Oscar-winning projects.
