Designed to deliver professional sound quality for audio recording, mixing and mastering, Symphony I/O Mk II is the ultimate music production centerpiece for any modern studio.
The new Symphony I/O Mk II comes with direct connectivity to one of 4 different platforms- Thunderbolt™, Pro Tools® HD, Dante™+ Pro Tools® HD, or Waves SoundGrid network.
Input and Output Flexibility
There is a Symphony I/O Mk II solution for everyone; the home studio, project studio, commercial recording studio and scoring stage. Choose from four base I/O configurations, 2×6, 8×8, 16×16, or 8×8 with 8 mic preamps and easily expand as your studio grows. With two module slots and the capacity for up to 32 inputs and outputs of A/D & D/A conversion per unit, Symphony I/O Mk II offers the best per-channel value of any interface in its category.
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.
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.
Symphony Control Software
Symphony Control software for Mac, is designed specifically for Symphony I/O Mk II audio interfaces. Symphony Control has been built from the ground up and replaces Apogee’s Maestro software for Symphony I/O Mk II users. Symphony Control delivers all the functionality of Maestro in a new, highly customizable user interface along with innovative new features like Talkback functionality, the simplified “Essentials” control window and an FX Send mixer feature, recently introduced as part of the Element Control software.
With the introduction of Symphony Control, customers can now use 2 Symphony I/O Mk IIs simultaneously for up to 64 channels of I/O over a Thunderbolt connection to their Mac. Symphony I/O Mk II combined with Logic Pro on a Mac delivers the most advanced native workstation available with superior quality high-channel count recording at incredibly low latency.
Standalone Routing lets you setup and use Symphony I/O Mk II without a computer. From the front panel touch screen you can set up Symphony I/O Mk II for use in these situations and more:
Connect Symphony I/O MkII to a Blu/Ray, CD Player or Power Amp for high end speakers. Symphony I/O Mk II is also an ideal high-end headphone amp.
Use Symphony I/O mkII on a Windows computer with Dante™, Pro Tools® HD, Waves SoundGrid®, or as a Standalone converter with a third party ADAT/AES PCI interfacing card.
Standalone AD/DA converters can be used alongside other digital gear: To expand other interfaces, to connect to live or studio digital consoles, to connect to broadcast equipment. With Standalone mode you can also bypass the converters of your existing gear.
For connecting to a Thunderbolt equipped Mac running Logic Pro X or any other Core Audio compatible DAW. Up to 32 simultaneous inputs and outputs per unit and up to 2 units per system for a maximum of 64 channels of I/O with latency as low as 1.35 ms in Logic Pro X (96kHz / 32 buffer).
Pro Tools HD
For connecting to an existing Pro Tools HD Accel, HD Native or HDX system. Up to 1 Symphony I/O Mk II unit connected to each HD port (max. 32×32 per unit).
Waves SoundGrid Network
Connect to the Waves SoundGrid System for studio, live and post production audio networking with real-time DSP for Waves and SoundGrid compatible third-party plugins.
Mk II Sound Quality- New 2x6SE, 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.
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.

Optional 8 Channel Mic Preamp Module
Symphony I/O MKII’s mic pre modules include Apogee’s Advanced Stepped Gain Architecture™, in which the circuit is dynamically optimized to provide superior bandwidth, ultra low noise and nonexistent distortion across the entire gain range. Whether recording powerful drums, dynamic vocals or delicate strings, your recordings retain the full impact, intricate detail and lifelike dimension of the original performance.
Symphony I/O Mk II’s Mic pre module also includes 8 channels of digitally-controlled analog inserts, so that outboard processors like EQ and compression may be inserted into the signal path between the mic preamp and the A/D conversion stage effortlessly. Because the inserts are digitally-controlled from Symphony Control software, any insert can be assigned to any input channel – there’s no need to physically reconnect your outboard equipment to a different insert channel.
