Apogee Symphony I/O Mk II 2×6 Special Edition offers the highest quality AD/DA conversion of the Symphony series. Designed specifically for mastering engineers whose critical work demands ultimate sonic performance, 2×6 SE takes advantage of the latest advancements in digital and analog audio technology to offer inputs with 124 dB (A) of dynamic range, THD+N of -116dB and outputs with 131dB (A) dynamic range and an astonishingly low THD+N of -118dB. We dare you to compare these specifications to our competitors – 2×6 SE’s combined specs outperform just about any AD/DA converter available today.
“These are real measurements, taken with our lab test equipment and not what I call ‘data sheet’ specs. My goal is to improve the overall design of the circuit and achieve greater real-world performance than what the component manufacturer claims on the data sheet. The new 2×6 card will outperform pretty much anything in the market…at any price”
— Lucas Van Der Mee, Apogee’s Senior Hardware Engineer
Symphony I/O Mk II 2×6 SE is available preconfigured for Thunderbolt or Pro Tools HD or it can be purchased as an expansion module for any existing Mk II configuration.
