Symphony I/O Mk II is a multi-channel audio interface featuring Apogee’s newest flagship AD/DA conversion, modular I/O (up to 32 inputs and outputs), intuitive touchscreen display and optional world-class microphone preamps. 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 three different platforms – Thunderbolt™, Pro Tools® HD or Waves SoundGrid® network.
- Best AD/DA conversion of any Thunderbolt™ audio interface
- Up to 32 channels of modular analog I/O with optional 8 mic preamps
- Best per-channel value of any interface in its category
- Choice of Thunderbolt, Pro Tools® HD (Mac/PC) or Waves SoundGrid® connectivity
- Ultra-low latency performance
- Intuitive touchscreen display and front panel control
- Designed in California, Built in the U.S.A.
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.
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.
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.
