Symphony I/O MKII Thunderbolt Chassis - No module included
True Thunderbolt Performance
Lowest Latency. Superior Sound Quality.
Symphony I/O Mk II Thunderbolt delivers the full potential of Thunderbolt 2 performance with the lowest latency, unmatched CPU efficiency and 2 ports for connecting additional peripherals.
Symphony I/O Mk II Thunderbolt relies on Apogee’s proprietary Thunderbolt driver, written from the ground up to offer unmatched performance and efficiency. When using Logic Pro X, latency has been reduced to an astounding 1.35 ms round-trip*, allowing you to monitor through your DAW, plug-ins included, simplifying your workflow and leveraging the power of your Mac. Even when your session’s DSP demands require a higher buffer setting, Symphony I/O’s ultra-low latency means no longer having to choose between power and speed.
To accommodate different workflow preferences, Symphony I/O Mk II Thunderbolt features optional direct hardware monitoring through Symphony Control Software with 0.6ms of latency.
* Logic Pro X at 96kHz / 32 buffer setting

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.
The Ins and Outs of Superior Sound
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.
