The 16x16 version of the Symphony I/O Mk II - Audio Interface from Apogee Electronics consists of the Symphony I/O Chassis outfitted with the 16x16 Mk II - Analog In/Out Digital Module. 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 additional I/O Module slot for adding another optional I/O card, 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 16x16 Mk II Module offers sixteen channels of analog input and sixteen channels of analog output for the Symphony I/O Mk II. Additionally, two channels of coaxial S/PDIF input and output is also provided. The A/D circuit has been refined to offer a streamlined circuit design, resulting in the most transparent signal path to the A/D stage possible. A dual-sum A/D stage is utilized where two conversion stages are summed for each analog channel, offering the lowest distortion and the greatest dynamic range of any A/D converter Apogee has ever designed.

The D/A section has been optimized with a more powerful and robust output driver that is capable of driving virtually any input without a decrease in performance, regardless of the load presented by the connected gear. The analog inputs and outputs are offered on DB25 connectors and require optional breakout cables, available in various configurations to suit individual requirements.
