StudioLive RML16AI 16-channel, 25-bus rack-mount Active Integration Digital Mixer

Rack-mount convenience, AI power, and total recall.

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.

Complete recallable touch control.

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. 

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®.

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.

The power of Active Integration™

StudioLive RM-series mixers are based on Active Integration™ (AI), a complete, networked, tightly integrated hardware/software ecosystem in which every touch point in the system interacts to enhance the user experience and solve practical problems in ways not previously possible.

Active Integration products combine powerful 32-bit floating-point DSP, wireless and wired networking, and proprietary software to solve real-world problems. PreSonus leads the industry in hardware/software integration, and Active Integration takes this concept to a new level, offering capabilities that have never been available before.

In PreSonus StudioLive RM-series digital mixers, Active Integration technology bridges the gap between the stage and studio. A powerful suite of integrated software makes it easy to mix and record a live performance and then take that mix to the studio, complete with levels, pans, and Fat Channel plug-ins. From there, you can use PreSonus’ Nimbit® distribution and promotion service to share and sell your recordings. The combination of StudioLive RM digital mixers, UC Surface control software, Capture recording application, Studio One DAW, and Nimbit publishing provides an end-to-end solution.

StudioLive Active Integration mixers have more than enough DSP to power a deep and clear mix bus, four internal effects buses, and two complete sets of Fat Channel EQ and dynamics settings per channel and bus so you can make quick A/B comparisons—all built on the same 64-bit architecture that makes Studio One® sound so amazing.

With Active Integration, new features and enhancements can be added in future firmware and software updates—and PreSonus has earned a reputation for regularly supplying such updates in its digital products. 

Actively integrated software.

PreSonus StudioLive RM-series mixers are tightly integrated with a suite of free, state-of-the-art software that helps you mix and record better and have more fun doing it. No other mixer near this price class offers comparable software.

Wi-Fi and wired networking.

PreSonus StudioLive™ RM-series digital mixers’ Active Integration™ technology includes powerful real-time, direct, wired and Wi-Fi remote control over a variety of features, using free Mac®, Windows®, and iOS® software.

It’s easy to create a StudioLive RM-series wireless network! 

Creating a wireless network may be new to you but no worries: We made it easy to connect your StudioLive RM mixer to a wireless network.

If you connect a wireless router to your StudioLive RM mixer with an Ethernet cable, the system assumes (just like Mac OS X and Windows) that you have permission to be on that network, and your mixer automatically connects to it. If you want to go wireless, you can scan for available wireless networks and scroll through them by name. If you name your wireless network “StudioLive,” your mixer will even connect automatically.

You never have to create an IP address or enter a subnet mask, or even know what those are. 

Bottom line: If you’ve ever connected your computer, iPad, or iPhone to a wireless network, you already know how to connect your StudioLive RM mixer to the network. 

That said, we understand that corporate, educational, and government environments require secured, firewalled networks, which requires some expertise. We gave you that capability, too: The networking backbone of PreSonus AI technology is registered with IANA (Internet Assigned Numbers Authority). Simply open port 47809 to let AI control network traffic through. 

 Upgradeable networking and recording connections.

Like all StudioLive mixers, every RM-series mixer integrates a multi-channel recording interface. A pair of FireWire S800 ports let you connect the StudioLive RM mixer to a Mac or Windows PC for recording. The integrated recording interface can send up to 54 audio streams to a computer and return up to 34 playback streams.

Every StudioLive RM-series mixer offers a special USB 2.0 port with an included USB wireless (Wi-Fi) LAN adapter for connection to your wireless router. A standard Ethernet port provides a hard-wired connection to your wireless router. So you have two different ways to connect to a router and can use whichever works best for the gig. 

But you aren’t limited to FireWire and standard Ethernet. The FireWire S800 and Ethernet ports come preinstalled on a card that can be replaced with optional Dante, AVB, or Thunderbolt cards so you can use the latest technology. A standard Ethernet port provides a hard-wired connection to your wireless router. So you have two different ways to connect to a router and can use whichever works best for the gig.

A gigantic console in a few rack spaces.

If a StudioLive RM mixer were an analog console, it would have 4-foot-long channel strips packed with knobs and buttons or it would require a massive outboard rack of expensive signal processors! Instead, all that processing fits in three (RM16AI) or four (RM32AI) rack spaces under software control.

Each StudioLive RM mixer channel and bus has its own studio-grade compressor, limiter, gate/expander, and 4-band parametric equalizer. Each input channel, aux and FX bus also has a highpass filter, and input channels have polarity invert. 

It all is part of a remarkable processing and routing section known as the Fat Channel.

Unlike most competing digital mixers, there are no limitations or compromises, no shared resources, no figuring out what processing is available where. You have all of the processing available at all times.

Because StudioLive RM mixers have so much processing power and blazing-fast RAM, you can create two complete sets of EQ and dynamics-processor settings for every channel and bus and then make quick A/B comparisons at the touch of a button in UC Surface. Does the guitar player use a Strat for some songs and Les Paul for others? Don’t use up two channels; create two completely different Fat Channel settings for each guitar and access them with the touch of a button before he has the next guitar strapped on.

It’s like having two complete channel strips on every input and output—but simpler and more efficient!

 Fat is beautiful.

Engaged by touching any Select button in UC Surface, the StudioLive RM-series Fat Channel section delivers a compressor, limiter, gate/expander, and four-band fully parametric EQ on every channel and mix bus. You also get a highpass filter on every channel and aux bus, a lowpass filter on the main mono/center bus, and polarity invert for each channel—not to mention routing, panning, and scene and setting store and recall.

To let you get the most from all of this processing power without descending into menu purgatory, we designed UC Surface with an intuitive graphic interface. It’s easy to instantly access any function and get clear, visible feedback so you know at a glance which channel or bus you’re processing. Type in values or adjust them with a graphic display in an easy-to-use parameter box. You’ll love how quickly you can work!

Plenty of graphic EQs, too!

You get graphic EQ on 12 aux buses and the main left, right, and mono/center channels—with two settings for each, all at the same time, without compromising other resources. Each graphic EQ has an A/B option, so you can, for example, boost the bass for a rock band and then switch over to a “smiley face” for intermission program music. 

Dedicated I/O.

View the front of a StudioLive RM-series rack-mount mixer, and you’ll see a straightforward jackfield with XLR channel inputs, XLR mix outputs, and other important connections.

With a StudioLive RM-series mixer, every channel has an individual analog XLR mic input on the front panel. Every aux mix has a dedicated XLR Mix Output on the front panel, mirrored in DB25 connectors (Mix Outputs 1-8 and, with the RM32AI, 9-16) on the rear. You never have to guess which input feeds which channel or which aux mix goes to an output because they’re always the same. Aux Mix 1 goes to Mix Output 1, Aux 2 to Mix Out 2, and so on. It’s all part of a design that enables you to work quickly and without confusion.

Want the stereo main bus output in digital format? No problem: The StudioLive RM series’ preinstalled digital option card also includes coaxial S/PDIF output.

The sound is pure PreSonus.

Getting a great-sounding mix depends in part on how good the mixer’s components are and how well the algorithms perform. That’s especially true with RM Series analog (but digitally recallable) XMAX™ mic preamps. 

Of course, getting a great-sounding mix depends partly on your skill, assisted by StudioLive RM-series mixer’s ease of use, features, and integrated software. But you also need great microphone preamps and converters, a clean signal path, and well-written algorithms that perform at a high level.

The StudioLive’s XMAX™ Class A preamplifiers deliver more headroom, deeper lows, smoother highs, and a richer overall sound than the preamps found in competing mixers. High-headroom, 32-bit floating-point processing is used for all digital mixing. The Burr-Brown digital converters on every input and output are state-of-the art, with 118 dB dynamic range.

Recallable Preamps

Until now, recallable mic preamps meant using a cheap integrated circuit that compromised sound quality in favor of digital recall. We didn’t want to change the sound of our superb Class A preamps, so we came up with a separate digital volume-control circuit ahead of the analog preamp. Voila! Digital recall of quality analog mic preamps!

 MAX Headroom

At PreSonus, we know that the mic preamplifier is a key component in the sonic quality of a recording. StudioLive AI-series mixers include custom-designed, high-voltage, discrete, XMAX Class A microphone preamplifiers that are suitable for use with all types of microphones.

The job of a microphone preamplifier in a digital mixer is to boost a microphone-level signal to line level before conversion to the digital domain. A good preamp boosts the level to almost 400 times that of the original signal, making the preamp one of the most important stages in an interface. A cheap, off-the-shelf, op-amp-type mic preamp delivers thin, noisy, harsh results.

But with XMAX preamps, the sonic quality is limited only by the microphones you plug into them.

XMAX preamplifiers are built with three key elements:

  • High Voltage. The XMAX preamplifier runs on power rails of 30V. Most off-the-shelf, op-amp-based designs run on power rails of 10V to 18V. Higher-voltage power rails deliver more headroom, deeper lows, smoother highs, and a richer overall sound.
  • Discrete components—not op-amps. We only use genuine transistors, resistors, and capacitors. Op-amps add noise, coloration, and harshness to a signal. Our discrete design delivers ultra-low noise and transparency.
  • Class A. Class A circuits have no crossover distortion and deliver purer, clearer, and more musical results than the Class AB designs that are found in many preamps.

The net result of the XMAX preamp design is high headroom, low noise, wide dynamic range, extended frequency response, and—most important—musicality and transparency, with smooth highs, solid deep lows, and everything in between.

 Jet-powered synchronization

The StudioLive RM mixer’s synchronization to your computer is stable and robust, thanks to JetPLL™ synchronization technology. JetPLL™ incorporates noise shaping to virtually remove all audio-band jitter, ensuring near-perfect clock performance and optimal converter performance when networking two or more digital-audio devices.

JetPLL quickly locks to any digital format through a wide range of frequencies and is extremely robust and tolerant of wide variations in clock frequencies.

As a result, you’ll experience better stereo separation and clearer, more transparent audio.

Complete store and recall—instantly

With UC Surface, it’s very quick and easy to save all of your StudioLive RM settings for quick setup and recall—unlike some digital mixers

Two factors work against getting that Perfect Mix with an analog mixer. First, the Perfect Mix can be hard to reproduce a week, day, or hour after you perfect it. And second, a good mix should be dynamic: levels, effects, and EQ should be tailored to each song or segment of the show, service, or presentation. This adds up to a lot of settings to remember and reset at every performance.

That's where the power of digital comes in: UC Surface battle-ready software lets you save all of your digital settings for quick setup and recall. Unlike some digital mixers and their associated software, StudioLive RM-series mixers with tightly integrated UC Surface make it fast and easy.

With UC Surface, you can save and name scenes that include every setting on the mixer—or save just the Fat Channel settings. Copy-and-paste settings across multiple channels and buses. Save individual DSP effects for ultimate ease, speed, and control. 

In short, you’ll love the fast, intuitive workflow offered by UC Surface’s straightforward, clearly marked controls; Windows 8 and iPad touchscreen support; and drag-and-drop implementation.

 Make the scene—instantly!

UC Surface makes saving and recalling scenes even faster and more convenient with eight user-assignable Quick Scenes that allow you to create a scene without storing it to permanent memory and giving it a name. This is especially useful when mixing multiple bands that you might not ever mix again—and to keep important stored scenes at your fingertips.

This means that for fixed applications like clubs, churches, and auditoriums, you can always count on the same sound and can fine-tune scenes for different songs and call them up instantly. And it lets rank amateur volunteers successfully operate a StudioLive RM-series mixer. 

 “WOW! How did you get that snare to sound so good?”

Don’t tell them it was one of the 50 StudioLive Fat Channel channel presets.

StudioLive’s Fat Channel lets you apply the equivalent of a six-foot rack of signal processors to every input. If you’re an experienced sound person, you’ll love all the options. But if you’re new to pro audio, gating, compression, limiting, semi-parametric equalization, and so on, can seem pretty complicated—which is why we’ve built in 50 excellent preset starting points for optimizing the sound of instruments, vocals, and spoken word. 

Before we released the first StudioLive mixer, we sent some out to professional sound mixers and engineers, let them tweak to their heart’s content under actual live and studio conditions, and then stored the results in factory presets. You get the benefit of their years of experience at making drums, percussion, guitars, keyboards, horns, vocals, and spoken word sound their best.

With StudioLive RM-series mixers and UC Surface, these presets, as well as your custom settings, can be organized and browsed by category so you can quickly find your favorite vocal preset without scrolling through horn and guitar presets. An AutoStore feature regularly saves your current settings in case the power fails.

And of course you can alter, rename, and generally customize each preset and save it in any of 50 empty storage locations. 

With the RM-series mixers, we’ve also added a new Audition mode for presets. Turn on Audition, and you can instantly hear the preset as you select it from the list. Once you find the preset you like, feel free to tweak the settings; when you load the preset into the channel, it will load with your tweaks. If you decide not to load a preset, just turn Audition off, and the Fat Channel will return to its current settings.
