The Apogee Symphony I/O MKII features world-class conversion, intuitive touchscreen control, and a modular design to accommodate any studio configuration or future growth—Waves SoundGrid network audio connectivity and 16x16 analog line I/O
In the early days of DAW recording, Apogee’s dedicated converters became an industry standard and were primarily used as a secondary front-end to bypass the converters of Pro Tools interfaces. While Pro Tools interfaces have come a long way since then, Apogee hasn’t been sitting on its hands. Not only have their converters gotten better after 30 years of leading the field, they have been incorporated into all-in-one modular interfaces that are capable of direct connection to Pro Tools via PT HD ports. They also offer your choice of Thunderbolt connectivity, as well as Waves SoundGrid and Dante network audio systems. To meet the current demands of audio professionals in a volatile marketplace, Apogee offers the Symphony I/O Mk II—a multi-channel audio interface featuring Apogee’s latest flagship AD/DA conversion, modular I/O (up to 32 inputs and outputs), intuitive touchscreen display, and optional world-class microphone preamps.

Comprehensive control via front-panel touchscreen
For convenient setup and control, all essential input and output settings can be accessed from Symphony MII’s front-panel touchscreen. It gives you easy access to input selection, monitoring levels, mic pre gain, or system calibration to match the levels of the other analog gear in your studio. All visual feedback critical for recording and monitoring is presented by high-resolution TFT display. 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.
Making modular merriment
A common dilemma of gear acquisition facing both manufacturer and customer was hoping that the unit you wanted had the right I/O for your system. Disappointment prevailed when I/O didn’t match up. Some manufacturers went as far as to consult with pro audio salesmen to see what their customers were requesting, but that was still hit or miss.
Challenge accepted! Problem solved with the Symphony I/O MKII. The Symphony’s I/O Modules are designed to future-proof your investment in Apogee sound quality. Representing over 30 years of Apogee R&D and design excellence, these powerful modules deliver 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.
Additionally, if you already own an original Symphony I/O, you’re still good to go. The Symphony I/O Mk II chassis can increase the longevity of your system by offering backward compatibility with the first-generation 2×6, 8×8, 16×16 and 8 channel mic preamp I/O modules—investment saved.
What is SoundGrid?
SoundGrid is an Audio-over-Ethernet technology developed by Waves. It allows you to stream high counts of digital audio channels (up to 128) and to process that audio through plug-ins at ultra-low-latency (as low as 0.8ms) over a 1Gb network. This makes SoundGrid a great fit for any environment, from simple project studios, to live venues, to complex networked recording and broadcast facilities.
SoundGrid is a proprietary Ethernet Layer-2-Protocol and EtherType. In essence, SoundGrid is a way to move audio data between devices that "speak the SoundGrid language" and are connected to the same local network. These devices automatically convert SoundGrid to different audio formats and vice versa.
Audio is routed and streamed between I/O devices and servers connected to the same network. I/O devices convert SoundGrid packets to and from other audio formats. Servers receive audio from I/O devices, handle plug-in processing, and send the processed audio back.
To allow for continuous, uninterrupted traffic, only SoundGrid devices should be connected to the network. In other words, SoundGrid is a private network. You can still use different network ports on your computer for other networks (such as internet).
Audio networking, scalability and flexibility
SoundGrid systems are flexible and can be easily adapted and configured for optimal effectiveness per channel count, processing capabilities, routing and sample rate. Adding or removing I/O or servers is quick and effortless.
Using only one Ethernet cable per device (Cat 5e/6 STP or Cat 7) greatly reduces cable runs and interference.
SoundGrid allows for server redundancy (currently up to 1 redundant server), parallel networks, clock fallback schemes, and automatic SoundGrid-host recovery.
Option card slot for future connectivity
If you’re currently working in Pro Tools | HD, thinking about going Native with Thunderbolt, or setting up an audio over Ethernet network, the Option card slot offers flexibility for the present as well the future. As new platforms develop and audio recording workflows evolve, Apogee engineers will create new cards to accommodate technological advances, thus prolonging the life and relevance of your Symphony MKII, For example, Dante Audio over IP network connectivity is coming soon to a Symphony I/O MKII near you—so stay tuned.
Dynamic temperature control
Let's face it, when it comes to prolonging the life of electronics, the only thing running through it that should be hot is your licks. To keep the Symphony I/O Mk II running at optimal temperature, it features advanced controls to ensure 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
Designed specifically for Symphony I/O Mk II audio interfaces. Symphony Control for Mac has been built from the ground up and replaces Apogee’s Maestro software. Symphony Control delivers all the functionality of Maestro in a new, highly customizable user interface along with innovative new features, such as talkback functionality, a 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, you can use 2 Symphony I/O Mk IIs simultaneously for up to 64 channels of I/O over a Thunderbolt connection (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 with incredibly low latency.
Optional hardware remote control via Apogee Control software
Symphony Control software also provides compatibility between Symphony I/O Mk II audio interfaces and the Apogee Control hardware remote accessory. The optional hardware remote control features a Symphony-inspired control knob, three control-knob focus buttons, plus 8 user-configurable buttons that grant direct access to a wide range of Apogee Control software functions. Sold separately, Apogee Control hardware remote connects directly to your Mac via included USB cable.
Standalone Routing lets you set up and use Symphony I/O Mk II without a computer. From the front-panel touchscreen you can set up Symphony I/O Mk II for use in the following 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 a third party ADAT or AES PCI interfacing card to use Symphony I/O MkII converters on a Windows Machine.
- Standalone AD/DA converters can be used alongside other digital gear. For example, to expand other interfaces, connect to live sound or studio digital consoles, or broadcast equipment. With Standalone mode, you can also bypass the converters of your existing gear (just like the days of yore when Apogee saved the day).
