Legendary Sound Quality
Apogee engineers have made it their passion to improve every new flagship product by using the latest in electrical components and designing optimized circuitry that often exceeds the expectations of the component manufacturer. This is the Apogee Advantage. Symphony I/O Mk II is the culmination of this 30 year commitment and raises the bar on all Apogee products before it with even better audio clarity and sonic transparency. In fact, when equipped with either the new 8×8 or 16×16 Mk II I/O modules, Symphony I/O Mk II outperforms all other multi-channel audio interfaces available for Pro Tools HD or Thunderbolt based systems, making it the flagship audio interface for the entire professional audio industry and the obvious choice for countless GRAMMY winning artists, producers, songwriters and engineers.

The Magic is in the Modules
The I/O Modules are the sound and soul of Symphony I/O Mk II, and represent 30 years of Apogee R&D and design excellence. These powerful Modules deliver Apogee’s core competency: superior sounding digital audio recording. With 3 available I/O Modules and an 8 channel mic preamp module, you can choose from base configurations or expand to grow your studio’s capabilities.

Symphony’s I/O modules are designed to future-proof your investment in flagship Apogee sound quality. If you own an original Symphony I/O, the Symphony I/O Mk II chassis can increase the longevity of your system by offering backwards compatibility with first generation 2×6, 8×8, 16×16 and 8 channel mic preamp I/O modules.

Option Card Slot for Future Connectivity Options
Symphony I/O Mk II’s new option card feature will future proof your investment and your studio. Working in Pro Tools HD now? Thinking about going Native with Thunderbolt or setting up an audio over ethernet network? The Option card slot offers flexibility for the present and the future, as new platforms develop and audio recording workflows evolve.

Front Panel Touchscreen with Comprehensive Control
All of Symphony I/O Mk II’s essential input and output settings can be accessed from the front panel touchscreen. 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. Without looking at your computer, Symphony I/O Mk II lets you see metering for up to 64 channels of I/O, 32 IN x 32 OUT – signal levels, polarity, muting, phantom power and Soft Limit.

Dynamic Temperature Control
Symphony I/O Mk II features advanced controls to keep the unit running at an ideal temperature, ensuring the highest level of performance and reliability. The new temperature controls are complemented by an improved fan and chassis ventilation design, which allows adequate component cooling to occur quietly.

Why do I need a good AD/DA converter?
Whether you record with a vintage Neve console, the best Neumann microphones or colorful mic preamps, a high quality AD converter is imperative to capture every nuance of your analog gear into your DAW. Without this, you will miss many of the subtleties and details that simply cannot be added back later with plugins. Similarly, the DA stage is essential to your perception of the recorded audio tracks. When mixing, regardless of what speakers you are using, if the converter is masking or having any effect on your audio, you could end up overcompensating with EQ, compression or other effects and failing to address other problematic details.

With Symphony I/O Mk II, you will hear more definition in each track and instrument of the mix, making it easier for you to make intelligent adjustments and achieve the ideal balance. Tracks will blend more harmoniously and mixing will simply be easier. The high end will be clear and not as brittle while the low end will be tighter than ever and more defined. This sort of unmatched audio quality can be noticed and appreciated by any listener.

Apogee Engineering Advantage
For over 30 years, Apogee has consistently redefined the state of the art in digital audio hardware design. We never rest on the laurels of our previous award-winning products – we’re constantly evaluating the latest technological developments in analog and digital components, platform connectivity and user interface advances to design better performing, intuitive products that meet the needs of any audio professional.

As an example of the Apogee Advantage, Symphony I/O Mk II uniquely employs a fully differential op-amp as a fundamental building block throughout its analog circuits. The very latest iterations of this technology offer astounding performance – vanishingly low noise and distortion, lightning-fast slew rate and out-sized current output capability, all in a power efficient and small package. These components offer performance that’s orders of magnitude superior to what’s found in most competitive audio interfaces, and are an important factor in Symphony I/O Mk II’s ability to offer up to 32 channels of state-of-the-art conversion in one 2U package at an incredible price per channel value.

Mk II Sound Quality–New 8×8 and 16×16 Modules
Like every flagship product we’ve introduced, Symphony I/O Mk II benefits from on-going expertise that constitutes the Apogee Engineering Advantage, once again pushing forward the state-of-the-art.

Symphony I/O Mk II includes the most refined analog-to-digital converter we’ve 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. A Dual Sum A/D stage – where two conversion stages are summed for each analog channel – offers the lowest distortion and greatest dynamic range of any A/D converter we’ve ever designed – you get digital recordings that are true to your analog inspiration.

Symphony I/O MK II’s D/A section has been optimized with a more powerful, robust analog output driver. This newly designed high current, low impedance circuit is capable of driving virtually any input with absolutely no decrease in performance, regardless of the load presented by the connected gear. This becomes especially important when connecting vintage gear with difficult load impedances and elevated operating levels, sometime over long cables – Symphony I/O MK II maintains fidelity and punch.

Audiophile-Grade Headphone Monitoring with Constant Current Drive
Symphony I/O Mk II features a single ultra high-fidelity DAC and headphone amplifier featuring Apogee’s Constant Current Drive technology, first introduced in the Apogee Groove. 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.

Includes ESS Sabre32 DAC Technology
ESS Sabre32 32-bit Hyperstream DAC with Time Domain Jitter Eliminator offers unequalled dynamic range, ultra low distortion, and unmatched audio clarity free from input jitter.
