PreSonus AudioBox 1818VSL USB Audio Interface

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!
