Maximum Control for Your StudioLive AI Rig

If you want serious flexibility, then build your live sound or studio recording rig around the PreSonus StudioLive CS18AI AVB Ethernet control surface. When you couple the CS18AI's 18 motorized faders and extensive onboard controls with StudioLive gear, you can get upwards of 64 channels of mixing and recording I/O, plus total control of PreSonus Studio One. AVB Ethernet delivers both instantly responsive control and bidirectional audio, allowing you to monitor through your CS18AI and provide talkback, room mics, or control room recording capabilities. However you put it to work, the PreSonus CS18AI AVB Ethernet control surface will add a special level of convenience to your music rig.

PreSonus StudioLive CS18AI Control Surface at a Glance:
  • AVB delivers total control from the stage to the studio
  • Flexible StudioLive technology lets you expand your rig
  • Onboard I/O provides vital communication and more
  • FREE Plug-in Suite for Your Favorite DAW
AVB delivers total control from the stage to the studio

Forget about cumbersome snakes or dropping cable in your walls - with the PreSonus CS18AI control surface at the heart of your StudioLive RM mixer rig, all you need is a single standard Cat 5e Ethernet cable, and you're all set. That's because your CS18AI operates on the same AVB Ethernet protocol as StudioLive RM mixers. This not only provides extremely responsive control over your mix, but it also lets you send audio both ways, allowing you to use your CS18AI mixer (or mixers) as stage boxes or remote preamps.

Flexible StudioLive technology lets you expand your rig

Over the decades, Sweetwater Sales Engineers have helped countless studio and live sound professionals adapt their rigs to ever-changing needs. That's one of the reasons we're so excited about the PreSonus CS18AI and StudioLive gear. With this kind of a setup, you're free to grow and change your system as needed. If 32 channels isn't enough, you can cascade two StudioLive RM mixers together for expanded I/O, and thanks to the CS18AI's scribble-strip display and DCA groups, managing a higher channel count is totally painless. What's more, you still get the StudioLive AI iOS integration, so you can always add iPhones or iPads for personal monitor mixing and remote access.

Onboard I/O provides vital communication and more

One additional and highly important way that the PreSonus CS18AI differs from typical control surfaces is its integrated I/O. Acting as a 4-in/2-out AVB audio interface in its own right, the CS18AI provides you both a pair of line-level inputs and a pair of microphone inputs as well as stereo XLR and headphone outs. This I/O configuration lets you monitor on headphones or speakers while providing talkback and room mics. And since the onboard mic inputs are remote XMAX preamps, you're all set to record in the control room with the same amazing sound you'd expect from your StudioLive RM mixer.

FREE Plug-in Suite for Your Favorite DAW

PreSonus delivers more value than ever with their mixers and interfaces, thanks to the Studio Magic Plug-in Suite. This extensive collection of seven popular plug-ins covers models of top studio gear from manufacturers such as Maag Audio, Lexicon, and Arturia, adding up to hundreds of dollars of extra value. Punch up your mix bus with Brainworx's bx-opto, add ambience with Eventide's SP2016-inspired Stereo Room reverb, fire up transients with SPL's Attacker, and much more. And since these plug-ins are available in AAX, VST, and AU formats, they're compatible with any DAW you choose.

PreSonus StudioLive CS18AI Control Surface Features:
  • An Ethernet AVB control surface that integrates with StudioLive RM AI mixers and Studio One DAW software
  • 18 x 100mm touch-sensitive motorized faders let you take control of your mixer channels and DAW tracks
  • 4-in/2-out AVB audio interface offers monitoring, talkback, and control-room recording options
  • 64px x 96px scribble-strip display with pan indicator included on all 16 channel faders
  • Variable-color select buttons provide easy at-a-glance channel and group identification
  • 4.3" color touchscreen lets you dive into deeper setup control and settings manipulation
  • Full PreSonus Fat Channel DSP control onboard makes setting up channels simple

Very Happy with the purchase

I wanted to wait till I used the unit in a live application before I created a review, and I just completed that journey. I bought it specifically to work with my RM32AI unit, in a live sound environment, I already have a 27 inch touch screen monitor, production PC, along with a wireless router and up to 6 ipad \ iphone units connected in, along with a plethora of VST effects, working well together. I did my homework - to use this control surface with headphones as well as a talk back mic and an iphone playing mp3's before an after the show, I needed an AVB switch among other things like cables and such. I chose the MOTU AVB switch for this. I learned that I needed to spend time with AVB configuration and firmware updates well in advance of using it live, so that I had everything setup and working together. It helped to already know the Universal control app because it provided a more intuitive interface for setup. Not that the CS18 is hard to learn - its actually easy. I just found that having a a few larger displays available as I was learning, worked better for me. While this unit has a small profile, it is powerful, and well laid out. It took a few hours to really wrap my head around navigation, as the entire system is wide (control of 64 channels) and deep (fat channel, special effects - even recording and playback control). You do not want to show up to a gig without having a few hours at least, of hands on time to become comfortable with it and to build out 'the show' mix - from each channel, to monitor mixes, to DCA filters, to talkback, to scenes, to effects, to the mains. There is a lot to do if you have to start from scratch. HOWEVER, after working through it once, I found I don't even have to think much about what to reach for, or how to access it. The nice thing for me was, I already had a good portion of the show setup done in the RM32AI, using Universal Control, prior to getting this control surface. You can imagine my surprise after connecting everything up, when the faders moved into position, and the scribble strips showed each channel name, from the first scene in the RM32AI. My hats off to PreSonus - the entire solution, from the RM32AI, to UC Surface, to the CS18AI to Studio One is a powerhouse. Clean sounding, good control, great value.

Connection Issues UPDATE:

This is an update to my previous review. The original unit was defective, I have since received a new unit. The difference between the two is night and day. Now that I know that my unit had a defect I can write a review for the way that it functions under normal operation. The touch screen has ZERO latency compared to my original unit, which is much nicer. More importantly however, is that I don't have to connect to my network every time I want to use it, the CS18 now remembers my network. The faders function perfectly. Zero connection issues/trouble now. I'm very pleased as this unit has made mixing a lot more fun for me. This was the experience I was originally hoping for.

Complete Control

The CS18 is the product I have waited for for years. It has every control parameter I need to get my hands off the mouse and keyboard and back on faders and knobs. In addition I can use it on location to record with the same studio quality by adding my RM32. This is hands down the best solution for the price!

Great under the fingers!

I bought this to go along with my RM32AI... It has a great feel and is pretty easy to use. I would have given it a higher rating, but I don't like that you have to buy an AVB switch to use ALL the features of this unitand the EQ is a little hard to navigate live compared to the the UC Surface software (which I really like) I use on my IPad. In all I am happy to have it and would recommend the combo (RM/CS) to a fellow sound engineer.

Awesome with RM32AI, Studio1

I've had this unit for a bit more than 3 months. It's been out to gigs and shows, and has worked a treat with a RM32AI. Put the mixer on stage,Marin a single Ethernet and we're in business. It's been rock solid when controlling the RM32AI this way over a wired links no dropouts, no lockup so, no issues. Controls are responsive, meters are fast enough, it's nice to have a hardware control surface. Also I use this as a remote for Stduio1 when recording and mixing, it works well for that application too. Again, hard wired into my network, controlling a computer that's also hard wired, it's been stable and reliable. Certainly a lot more compact than my Mackie units. I do wish the transport controls were lower and on the right, and I wish it had a jog wheel. I wish the touch screen was a bit more responsive, in the world of iPhones its sluggish and a bit cumbersome. I've not dared to use this unit wireless at a gig... Sales engineer Dave Brow did a great job, as always, of making sure I got what I needed.
