StudioLive CS18AI
Powerful, intuitive network control.
Equipped with 100 mm touch-sensitive motorized faders and AVB networking, the StudioLive® CS18AI control surface provides a compact, intuitive mixing solution for PreSonus® StudioLive RM16AI and RM32AI rack-mount digital mixers and Studio One® 3 digital audio workstation. The CS18AI connects to the network with a CAT5e or CAT6 Ethernet cable, eliminating the need for cumbersome analog or digital snakes and stage boxes, and offers a host of other useful features. It adds up to a powerful mix control system with a fast, intuitive workflow and the latest networking technology.


Complete control of StudioLive RM-series rack mixers.
Networked with StudioLive RM-series mixers via PreSonus UCNET technology, the StudioLive CS18AI offers complete hardware control of up to 64-channels and all mixer features. Keep your mixing I/O onstage in a rack, while running the mix from hundreds of feet way, using a lightweight Ethernet cable instead of a cumbersome analog snake and separate stagebox. Set up a wireless network and add an iPad®, a large Windows® 8/10 touchscreen, a Mac® or Windows laptop, or any combination for unprecedented mixing and control.

Extensive mix control for Studio One 3.
Unlike DAW controllers that give you some faders and generic controls that try to do too much with too little, the StudioLive CS18AI provides extensive hardware control for Studio One 3. Control channel faders and automation, PreSonus and third-party plug-ins, transport control, and more. Controlling Studio One with a CS18AI is like mixing with a large studio console—but more flexible.

Filter DCAs are better than layers.
Although you can navigate your mixes using traditional layers, a better solution is our unique Filter DCA groups, which bring the elements of the mix to you. Filter DCAs combine concepts of DCAs and view groups into an intuitive workflow designed to make your life easier when you’re in the heat of a live mix. For instance, rather than trying to remember which layer the lead guitar is on, select your guitar Filter DCA, and you'll have access to your guitar channels. This is going to change the way you mix! For more about Filter DCAs, see our UC Surface page.

Built-in, 4x2, AVB-networked audio.
Through the power and flexibility of AVB audio networking, the StudioLive CS18AI can not only transmit control data but can also send and receive audio channels across long distances. You get two mic/line inputs with PreSonus’ remote-controllable XMAX preamps and two line inputs that you can use as sources for the talkback, 2-track playback, or other sources from front-of-house. The CS18AI’s two TRS line-level returns are shared with the monitor line outputs and headphone output and can be sourced from any RM mixer output, including the solo bus, main mix, or any aux mix.
