The PreSonus StudioLive 16.4.2 AI is an immensely powerful 16-channel digital mixer with 16 Class-A XMAX preamps, onboard DSP and a Firewire audio interface -- perfect for live sound reinforcement and project studio recording. The highlight of the Active Integration (AI) DSP is PreSonus' Fat Channel, a full channel strip with 4-bands of parametric EQ, extensive dynamics, and an intuitive interface to make tweaking your sound as easy as can be. Fine-tune your mix as you walk around the room with wireless remote control via iOS devices or a laptop, and then leverage the FireWire interface to record the show and deliver it to the band as soon as they're off the stage.
