Computer system requirements:

Below are the minimum computer-system requirements for the AudioBox 1818VSL:

Windows

  • Windows® 7 x64/x32 SP1, Windows 8 x64/x32
  • Intel® Core™ Duo or AMD Athlon™ X2 processor (Intel Core 2 Duo or AMD Athlon X4 or better recommended)
  • 2 GB RAM (4 GB or more recommended)

Mac

  • Mac® OS X 10.8 or later
  • Intel Core Duo processor (Intel Core 2 Duo or Intel Core i3 or better recommended)
  • 2 GB RAM (4 GB or more recommended)

Windows and Mac Systems

  • USB 2.0 Port
  • Internet connection (only for activation)
  • DVD-ROM drive
  • Monitor with at least 1024x768 resolution
  • 20 GB hard-disk space
  • Internal or external 7200 RPM storage drive highly recommended

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 or MIDI signals. Monitor resolution for both PC and Macintosh should be no lower than 1024x768 pixels.
