Apogee Electronics SYM2 overview

  • 1Description

The Symphony I/O Mk II from Apogee Electronics is an advanced, flexible multi-channel audio interface featuring the newest flagship AD/DA conversion, modular I/O (up to 32 inputs and outputs), and an intuitive touchscreen display. The chassis provides two I/O Module slots for a variety of digital audio conversion options that form the interface side of the Symphony I/O Mk II. The front-panel touch screen offers convenient access to nearly every setting including sample rate, clock source, headphone & speaker output levels, meters for all I/O and section navigation, as well as input levels, digital I/O, and configuration settings.

The rear panel provides access to the two I/O Module slots that are capable of a combined thirty-two channels of input and output, while the two Thunderbolt connectors ensure compatibility with newer Mac computers. Also included are Wordclock I/O connectors & termination, an option card slot, and a quiet digitally-controlled fan to keep everything running cool.

The Symphony I/O Mk II features a single ultra-high-fidelity DAC and headphone amplifier  with Apogee's Constant Current Drive technology, which was first introduced in the Apogee Groove. The headphone amplifier dynamically compensates for non-linearities of any connected headphones, providing massive power while maintaining extremely low distortion and linear frequency response.

The optional five I/O Modules allow the user to choose from standard configurations, or customize the following – channel count, analog to digital input, digital to analog output, microphone preamps (requires an analog card), and digital I/O.

Note: Note! This is the Symphony I/O chassis only.

  • Legendary AD/DA conversion
  • Up to 32 channels of modular analog I/O with optional 8 mic preamps
  • Ultra-low latency performance
  • Intuitive touchscreen display and front panel control
  • Option card slot for future platform flexibility
  • Dynamic Temperature Control
  • Designed in California, built in the U.S.A.
