Based on the StudioLive™ AI-series mix engine and controlled with battle-ready UC Surface software for Mac®, Windows®, and iOS®, the StudioLive RM32AI and RM16AI 32-channel, 25-bus rack-mount Active Integration™ digital mixers are scalable, compact, and 100 percent recallable.

​Like all StudioLive Active Integration mixers, the RM series delivers unrivaled sound quality, XMAX™ Class A solid-state preamps, amazing DSP performance, direct Wi-Fi and wired LAN communication, fast and intuitive workflow, an onboard FireWire S800 interface, and a tightly integrated software suite for Mac®, Windows®, and iOS®, creating a streamlined working environment for both live and studio use.

We offer two StudioLive RM models. The RM32AI has 32 mic inputs and 16 Mix outputs and mounts in four rack spaces; the RM16AI has 16 mic inputs and 8 Mix outputs and mounts in three rack spaces. Otherwise, the two mixers are identical in every respect.

PreSonus® UC Surface control software for Mac, Windows, and iPad was carefully designed for intuitive and quick performance in a live mixing environment (but also serves well in the studio). It lets you take advantage of large-format Windows 8 touch computers.  And it gives you the big-mixer power of Filter DCAs.

When you’re mixing a live show, and the heat is on, you don’t have time to search for controls and meters, as you must do with most digital mixers. You never have that problem with a StudioLive RM-series mixer because every control you need to mix a show is under your fingers in PreSonus UC Surface remote-control software for Mac, Windows, and iPad®.

Battle-ready software

We call UC Surface “battle-ready” because some live gigs seem like a war zone, with danger at every turn. UC Surface has your back, enabling you to accomplish your mission quickly and confidently. UC Surface is extremely reliable, and its layout provides quick, intuitive access to everything you need during a show or studio session.

The software is the same on Mac, Windows, and iPad, so you only need to learn one app, regardless of platform. And it supports iPad and Windows 8 touchscreens (not included), taking full advantage of these intuitive multi-touch interface technologies. You can control your StudioLive RM mixer with your laptop, with or without touchscreen, or with your iPad, or any combination.

In UC Surface, you always know what each button, fader, and parameter box controls and which parameter each meter displays. Virtual faders and meters are clearly marked. Each parameter is controlled by a clearly labeled button or a parameter box that enables you to type in a value or adjust the parameter in a graphic display. And UC Surface’s well-planned layout enables you to manage everything you need at the same time.

You always have full use of all 25 dedicated mix buses (16 aux buses, 4 internal effects buses, the stereo mains, the mono/center main, and the stereo Solo bus), along with the tape return and digital return.

To further enhance your workflow, you can assign Channel Types. Channel Types will set a default channel name that can be customized, along with a channel icon for quick identification. Channel types will also setup unique channel filters for your presets, making it easy to find and audition Fat Channel settings designed specifically for that channel type.

Filter DCAs revolutionize your workflow.

Managing a mix with 32 channels and multiple effects returns can be a daunting task. Big, mega-expensive mixers have addressed the problem of managing complex mixes with population/view groups that reduce the channels you’re viewing at one time and DCAs that allow you to control a group of channels.

We’ve combined the best parts of these solutions—and removed the strict limits to the number of groups—by introducing Channel Types and Filter DCAs. With these tools, you don’t have to juggle multiple features or make critical decisions about which channels are most important.

With Filter DCAs, you can control and navigate your mix with finesse and precision. Start by choosing Channel Types, which assign an icon and name to a channel (kick, snare, guitar, and so on) so you can quickly identify what’s on each channel. UC Surface uses this information to create Filter DCAs automatically (Drums, Guitars, etc.). With this done for you, you can focus on setting up your mix. You can also create your own Filter DCAs with one or more input channels, effects returns, the tape inputs, and the digital returns.

A Filter DCA can contain any combination of the available input channels and effects returns, and you can create as many Filter DCA groups as you need—far more than with the population groups and DCAs offered by competitors. You can include the same channel in lots of different Filter DCAs, thereby slicing and dicing the mix in various creative ways.

Filter DCAs also work independently on each mix giving you control of the same group on the main mix or any aux mix. Say you want to turn up all the drums in the main mix and then turn them all down in the bass player’s aux mix; you can do it with ease thanks to Filter DCAs.

All of your Filter DCAs consolidate into one Filter DCA Masters view that even fits on an iPad, where you can mix the groups. Want to drill down? Just touch a button to access and adjust the mix of the channels within a Filter DCA group. Then exit right back to the Masters view. With your selection of Filter DCAs and the Masters view, you can create your own custom layer that puts exactly the channels and groups you need under your fingers.

This is going to change the way you mix!
