The Magic is in the Modules

The I/O Modules are the sound and soul of Symphony I/O Mk II, and represent over 30 years of Apogee R&D and design excellence. These powerful Modules deliver Apogee’s core competency: superior sounding digital audio recording. With multiple I/O and Mic Preamp modules available, you can choose from base configurations or expand to grow your studio’s capabilities.

More Intuitive. More Control.

Front Panel Touchscreen

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.

Stay Cool with Dynamic Temperature

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 can be accessed form the touch screen and control software and are complemented by an improved fan and chassis ventilation design, which allows adequate component cooling to occur quietly.

Symphony Control

Symphony Control Software

Symphony Control software for macOS gives you comprehensive access to all features and functions of Symphony I/O Mk II Thunderbolt. Set gain levels (preamp modules only), manage routing, control output levels, set calibration, set-up multiple mixers and more.

And with Symphony I/O Mk II Thunderbolt’s new Monitor Workflows, you can effortlessly configure and operate your monitoring system for Dolby Atmos, Sony 360 Reality Audio and other immersive audio systems with control of up to 32 Speaker outputs.

Symphony Control also features compatibility with the new Apogee Control hardware remote.

Control Hardware Remote

Symphony Control also provides compatibility between Symphony I/O Mk II audio interfaces and the Apogee Control hardware remote accessory. Apogee Control gives you instant access to input and output levels using the large Symphony-inspired Control knob and 3 control knob focus buttons, plus direct access to a wide range of software functions using the 8 user-configurable hardware buttons. Apogee Control hardware remote connects directly to your Mac using the included USB cable. Apogee Control is is sold as a separate accessory by authorized Apogee dealers worldwide. US customers can purchase Apogee Control in the Apogee web store.

Multi-unit support for up to 64 channels of I/O

Multi-unit support for up to 64 channels of I/O
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 mode

Standalone Mode

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:

Hi-Fi Systems

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.

Standalone/Expander Converter and preamps

Standalone AD/DA converters and preamps 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.

Legendary Sound Quality and Performance

The Ins and Outs of Superior Sound

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.

Make a Difference you will Hear
