APOGEE symphony i/o

Simply the best sounding interface Apogee has ever made

- The culmination of 25 years of Apogee's design excellence and experience
- Next generation converter quality
- Refined and updated circuitry with fewer, more advanced components:
  o Fewer components means a shorter audio path and more recording clarity and transparency
  o Lower converter latency
  o More efficient power distribution
  o Enhanced C777 clocking performance
- "Sound Amazing" remixed and remastered
- Optional mic preamp module
- Front panel control of headphone and output levels, and mic preamp gain (mic preamps optional)

Symphony I/O’s Audio Interface Modes (AIM)

With a 2 step adjustment using a single front panel encoder knob, AIM transforms Symphony I/O into an interface optimized for the most popular audio workstation environments. This feature allows users of Logic and Pro Tools HD for example, to easily switch back and forth between the two DAWs with the click of a knob and swap of a cable. If USB is your preferred mode, connecting to Core Audio compatible apps like Digital Performer and Cubase is just as easy. And Standalone mode calibrates Symphony I/O for simple and direct routing ideal for a variety of uses and applications including Pro Tools LE or Pro Tools M-Powered.

Symphony I/O, the highest end

Symphony I/O builds upon the award-winning design approaches of Apogee’s X-Series* and Rosetta Series converters*, the Big Ben master clock and the Trak2 mic preamps. It also refines and updates these proven designs with fewer but more advanced components while optimizing their performance with efficient power distribution. These enhancements allow audio to travel through less circuitry, offering lower converter latency, more accurate clocking and even more transparency and clarity in your recordings.

Analog design, the cornerstone of Apogee quality

Apogee's engineers do not merely rely on specs and data sheets when selecting converter components, they listen. Each component is auditioned and carefully selected to best reflect the characteristics of the Apogee sound. Symphony I/O’s audio path design is elegant and efficient, incorporating the most advanced opamps that offer better performance than multiple parts used in previous designs.

This design improvement minimizes the audio path circuitry and maximizes sound quality. And in the tradition of the X-Series and Rosetta series, the entire audio path is DC coupled, resulting in ultra flat frequency response and extremely low phase error.
