About Apogee Electronics Symphony I/O Mk II

Explore the Symphony I/O Mk II Waves SoundGrid Chassis, a high-quality, professional-grade audio interface that sets the standard for advanced, innovative, and sophisticated sound recording and playback. This multi-channel audio interface is equipped with Apogee's flagship AD/DA conversion and modular I/O, capable of supporting up to 32 inputs and outputs. It's designed to deliver superior sound quality for audio recording, mixing, and mastering, making it an essential centerpiece for any modern studio.

Experience the Apogee Advantage with the Symphony I/O Mk II. Apogee engineers have dedicated themselves to improving every new flagship product, using the latest in electrical components and designing optimized circuitry that often exceeds the expectations of the component manufacturer. This commitment is evident in the Symphony I/O Mk II, which raises the bar on all Apogee products before it with even better audio clarity and sonic transparency.

The Symphony I/O Mk II offers input and output flexibility, making it a versatile solution for home studios, project studios, commercial recording studios, and scoring stages. Choose from four base I/O configurations, 2 x6, 8 x8, 16 x16, or 8 x8 with 8 mic preamps, and easily expand as your studio grows.

The I/O Modules are the heart and soul of the Symphony I/O Mk II, representing over 30 years of Apogee R&D and design excellence. These powerful modules deliver Apogee's core competency: superior sounding digital audio recording. With multiple I/O and Mic Preamp modules available, you can choose from base configurations or expand to grow your studio's capabilities.

The Symphony I/O Mk II features a front panel touchscreen, providing easy access to all essential input and output settings. Change your input selection, monitoring levels, mic pre gain, or calibrate your Symphony I/O Mk II to match the levels of the other analog gear in your system. A high-resolution TFT display delivers all the visual feedback critical for recording and monitoring.

The Symphony I/O Mk II is also equipped with advanced temperature controls to ensure the highest level of performance and reliability. The new temperature controls can be accessed from the touchscreen and control software and are complemented by an improved fan and chassis ventilation design, which allows adequate component cooling to occur quietly.

The Symphony I/O Mk II includes the most refined analog-to-digital converter Apogee has ever designed. The analog stage uses the same fully differential op-amps as found in the original Symphony I/O, but now in a circuit precisely streamlined to provide the most transparent path to the A/D stage possible.

The Symphony I/O Mk II is also an ideal high-end headphone amp, featuring a single ultra high-fidelity DAC and headphone amplifier featuring Apogee's Constant Current Drive technology. This unique approach to headphone amplification dynamically compensates for the nonlinearities of any connected headphones, providing massive power while maintaining extremely low distortion and linear frequency response.

With a simple ethernet connection, Symphony I/O Mk II's industry-leading sound quality can be easily connected to your computer, shared between multiple rooms, multiple computers and supercharged with almost infinite real-time DSP power via Waves SoundGrid servers. Symphony I/O Mk II SoundGrid integrates seamlessly with all DAWs, providing endless possibilities for setups of every size for studio, live, and post-production workflows.

In conclusion, the Symphony I/O Mk II Waves SoundGrid Chassis is a high-quality, professional, advanced, innovative, and sophisticated audio interface that offers superior sound quality, flexibility, and intuitive control. It's the perfect choice for professionals seeking an audio interface that delivers exceptional performance and value.
