Specifications

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
4 GB RAM (8 GB or more recommended)

Mac and Windows Systems

Thunderbolt™ 1.0 or 2.0 port (NOTE: Your computer's motherboard must support Thunderbolt)
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.
