PreSonus StudioLive mixers redefined affordable compact mixing, forever changing the world and setting the standard for what digital mixers could be. Built from this award-winning legacy, the StudioLive CS18AI is a compact, intuitive mixing solution for the StudioLive RM16AI and RM32AI rack mount digital mixers and Studio One digital audio workstation. The StudioLive philosophy means being at home both live and in the studio, being easy to learn, and incorporating uniquely PreSonus workflows and features. Your needs are unique. PreSonus AI systems are designed to address your individual requirements. With several options for control and exclusive software integration features you can accomplish more with exactly the type of control and capabilities you need. The CS18AI connects to RM mixers with a single CAT 5 Ethernet cable. That enables Active Integration with PreSonus software including UC Surface software for control from iPads and Windows 8 touch computers, iPhone and iPod management of personal monitor mixes with QMix-AI, and direct Capture control for live recording and virtual sound checks. The CS18AI is the first live mix system that lets you control 64 channels from a 19-inch rack-mountable control surface. Our Filter DCA groups bring the elements of the mix to you. Rather than trying to remember which layer the lead guitar is on, simply select your guitar DCA Filter and we will bring it to you. Filter DCAs take concepts of DCAs and view groups and combine them into an intuitive workflow designed to make your life easier when you're in the heat of a live mix. No other mixing system can offer such compact and affordable mixing system that's so easy to use. Every aspect of the CS18AI was designed to help you mix with ease and reliability. RGB select buttons make it easier to identify channels, layers, and mixes based on the color. True touch sensitive faders know when your finger makes contact so the fader will never fight you and you can experience real automation functionality in the studio. The CS18AI lights your way through mixing with 146 illuminated buttons, sixteen high-64x96-pixel scribble strips, a touch-sensitive 4.3 inch. /109mm LCD display, and sixteen 11-segment LED level ladders. If you need to control it, we made it light up.
