A great choice for a wide variety of recording environments, the 22x24-channel Quantum 2 is PreSonus®’ fastest and best-sounding audio interface, taking advantage of the high-speed Thunderbolt™ bus and a no-frills, direct-to-DAW (no DSP added) signal path to achieve extremely low latency. Two combo mic/instrument/line inputs and 2 mic/line inputs with recallable XMAX preamps combine with cutting-edge 24-bit, 192 kHz converters with 120 dB of dynamic range to deliver superb audio quality. For more I/O channels, simply stack up to 4 Quantum 2 interfaces via Thunderbolt to create a monster 80x80 system. You also get MIDI and word clock I/O. Using the included Studio One Artist DAW or UC Surface control software, you can remote-control the preamps and many other features. To top it off, Quantum 2 owners get the Studio Magic Plug-in Suite free.

Computer system requirements:

Below are the minimum computer-system requirements for the Quantum 2 Interface. 

Mac

  • Mac® OS X 10.11.6 64-bit or later
  • Intel® Core™ i5 or better
  • 4 GB RAM (8 GB or more recommended)

Windows

  • Windows® 10 64-bit or later
  • Intel Core i5 or better
  • 4 GB RAM (8 GB or more recommended)

Mac and Windows Systems

  • Thunderbolt™ 1.0, 2.0, or 3.0 port (Note: Your computer's motherboard must support Thunderbolt. Thunderbolt 3 requires an adapter, not included.)
  • Internet connection (required for Studio One Activation and Content download)
  • Internal or external 7200 RPM storage drive highly recommended
  • 30 GB hard disk space
  • Monitor with 1366x768 resolution

Note: The minimum system requirements may differ for DAWs other than Studio One. Please check the requirements for your DAW of choice with its manufacturer.

Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio signals.
