Computer system requirements:

Below are the minimum computer-system requirements for your FireBox.


  • Windows XP SP2 (32/64-bit) or later, Vista (32/64-bit), Windows 7 (32/64-bit)
  • Intel Pentium 4 1.6 GHz processor or AMD Athlon 64 (Turion) (2.5 GHz or faster recommended)
  • 1 GB RAM (2 GB or more recommended)


  • Mac OS X 10.3.7 or later (10.4.11, 10.5.2 or later, or 10.6 recommended)
  • PowerPC G4 1.25 GHz or Intel Core Solo 1.5 GHz processor (2 GHz or faster recommended)
  • 1 GB RAM (2 GB or more recommended)

Windows and Macintosh Systems

  • IEEE 1394 FireWire 400 Port
  • Internet connection recommended
  • DVD-ROM drive
  • Internal or external 7200 RPM storage drive highly recommended

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) that you might experience while monitoring audio or MIDI signals.

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