PreSonus AudioBox 1818VSL USB Audio Interface
This USB audio interface from PreSonus is equipped with 2 instrument inputs and 6 combo mic inputs with high headroom preamps.

Recording bands and project-studio owners will love the revolutionary 18-channel, rack-mount PreSonus AudioBox 1818VSL because it has the power of an 18 x18 StudioLive digital mixer, including signal processing with near-zero latency and the same high-end pro audio quality, including high-headroom XMAX Class A preamps. Plus delay, reverb, and a complete PreSonus StudioLive 16.0.2 Fat Channel for compression, limiting, downward expansion, parametric EQ, and high-pass filter on all inputs and playback streams. These effects are so good that you can print them to disk or route them through your P.A. onstage!

The PreSonus 1818VSL sports 2 mic/instrument inputs and 6 mic/line inputs with high headroom XMAX(TM) preamps, 8-channel ADAT I/O, 2 effects buses, and more. It comes with PreSonus Studio One(TM) Artist DAW (Mac/Windows) and is compatible with virtually any recording software.

System requirements:

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

Windows

• Windows Vista, Windows 7 (32- and 64-bit)
• Intel Pentium 4 1.6 GHz processor or AMD Athlon 64 3000+ (Turion) (2.8 GHz or faster recommended)
•    GB RAM (2 GB or more recommended)

Macintosh

• Mac OS X 10.6 (Snow Leopard) or later (32- and 64-bit)
• Intel Core 1 Solo 1.5 GHz processor (Intel Core Duo or Intel Xeon processor recommended)
• 1 GB RAM (2 GB or more recommended)
• Windows and Macintosh Systems
• USB 2.0 Port
• Internet connection recommended
• DVD-ROM drive (required to install Studio One Artist)

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.
