Complete Mix Control

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. All StudioLive products are at home both live and in the studio, are easy to learn, and incorporate uniquely PreSonus workflows and features.

  • 18 100 mm, touch-sensitive motorized faders: 16 Channel, 1 Flex, 1 Master
  • Navigate using traditional layers or with intuitive PreSonus Filter DCA groups

The power of Active Integration™.

Your needs are unique. PreSonus AI systems are designed to address your individual requirements. With several control options and exclusive software integration features, you can accomplish more and have exactly the control and capabilities you need.

The StudioLive CS18AI connects to RM mixers with a single CAT 5 Ethernet cable. That enables Active Integration with PreSonus software including UC Surface control software for iPad, Windows 8 touchscreen, and Mac computers; iPhone and iPod management of personal monitor mixes with QMix-AI; and direct Capture™ control for live recording and virtual soundchecks.

Filter DCAs are better than layers.

We’ve never liked the complexity that comes with navigating your mix using channel layers. That’s why StudioLive mixers have traditionally featured a one-to-one channel configuration, with no layers. While the StudioLive CS18AI does support classic layer navigation, it also features our unique Filter DCAs for controlling and navigating your mix.

The StudioLive CS18AI is the first live mix system that lets you control 64 channels from a 19-inch, rack-mountable control surface. 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 you'll have access to your guitar channels. 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.

Mix in touch-sensitive

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 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; 16 high-res, 64x96 pixel scribble strips; a touch-sensitive, 4.3-inch (109 mm) LCD display; and 16 11-segment LED level ladders. If you need to control it, it lights up.

↓ What does "touch-sensitive faders" mean?

The perfect DAW controller
for Studio One.

With a simple Ethernet connection, the StudioLive CS18AI becomes the control for Studio One, giving you an instant studio upgrade and closing the loop between studio and stage. Now you can get the performance of a big mixing console in a compact controller with a natural feel. Other DAW controllers give you some faders and generic controls that try to do too much with too little. The CS18AI is a complete mix controller that doesn’t skimp on functionality. You get all the classic mixer controls and workflows while still keeping the footprint compact.

↓ What's the current Studio One functionality?


Built-in 4x2 networked AVB audio.

Through the power and flexibility of audio networking, the StudioLive CS18AI can send and receive audio channels across long distances with just a single Ethernet cable. Use the two mic and two line inputs as sources for the talkback, digital return, or networked sources for Channels 31 and 32 on StudioLive RM mixers. The two returns are shared with the monitor line outputs and headphone output and can be sourced from any output of the RM mixers, including the Solo bus, main mix, or any aux mixes.

↓ What’s AVB all about?
