A great choice for a wide variety of recording environments, the 26x32-channel Quantum 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 6 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 interfaces via Thunderbolt to create a monster 96x96 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 owners get the Studio Magic Plug-in Suite free and can upgrade to Studio One Professional for 50% off.

Computer system requirements:

Below are the minimum computer-system requirements for the Quantum 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  (Apple Silicon M1 support coming early 2021)
  • 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.

Music Connection Quantum review

“We quickly launched a previous session that had been problematic for two other USB and Firewire interfaces. Not only did that session run flawlessly using the Quantum, we added another 50 tracks and put them into record with no problem whatsoever!”

Barry Rudolph, Music Connection, December 2017

Audio Media Quantum review

“PreSonus has given DSP the boot to keep the processing path as slippery as an eel.”

Brad Watts, Audio Media International, February 2018

Sound on Sound Quantum review

“They've achieved low-latency performance that, with the exception of PCIe cards, is currently unrivaled by any interface I know of.”

Sam Inglis, Sound on Sound, September 2017

Sound & Recording Quantum review

“...zeigt, dass Innovation nicht zwangsläufig zu höherer Komplexität und immer kniffligerer Bedienung führen muss.”
