Pedigree Preamplifiers
PreSonus Audio has won numerous awards for designing the highest quality microphone preamplifiers in the industry at all price levels. The AudioBox USB is loaded with preamps that out perform any USB-based interface hands down. The preamplifiers in the AudioBox deliver high headroom, low noise and high gain giving you pure, full and rich sound.

Professional 24-bit converters
Most USB recording devices operate at 16-bit sample rate and use converters with dynamic range of less than 90dB. This translates into a pinched and relatively small sound. The AudioBox USB uses professional-grade analog to digital converters with dynamic range of 102dB and 24-bit sample rate so that the digital conversion is big, quiet and musical.

USB bus-powered
The AudioBox USB is USB bus-powered allowing you to take it anywhere inspiration hits. No wall warts, line lumps or power cables, just plug in to a powered USB port and you are ready to record.

Ready to hit the road
There's no plastic here. The AudioBox USB is housed in an all-metal chassis with metal knobs ready to withstand the rigors of travel. Toss it in your laptop bag and mobilize your music creation and production. Whether you want to record your shows, mix on the plane or write songs in your hotel room, the AudioBox is ready.

Tech Specs: Computer system requirements:
Below are the minimum computer system requirements for the AudioBox USB.

Windows
• OS: Microsoft Windows XP or Vista
• Peripherals: Powered USB 1.1 or 2.0 port.
• CPU/Clock: Pentium or Athlon at 900Mhz or higher recommended.
• Memory (RAM): 512MB or higher recommended.
  
  Macintosh
• OS: OS-X version 10.3.7 or later.
• Peripherals: Powered USB 1.1 or 2.0 port.
• CPU/Clock: PowerPC G4/800Mhz or higher recommended.
• Memory (RAM): 512MB or higher 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.
