The PreSonus SLM64AI Digital Mixer takes the StudioLive series to the next level by pushing the technology of previous models and adding all new features!
This 64-channel, 28-aux PreSonus StudioLive provides incredible signal-processing power per channel, easy store and recall of every setting, and the ability to record it all with just two mouse clicks. SLM64AI is built with next-generation Active Integration technology that adds unprecedented power.
For starters, you get twice as many internal effects buses and 31-band graphic EQs. Presonus has added six mute groups and user-assignable Quick Scene buttons. You’ll love the ability to create two complete sets of EQ and dynamics settings for a channel or bus and then make quick A/B comparisons at the touch of a button.
A built-in 48x34 FireWire S800 interface is standard equipment but Thunderbolt and Ethernet (Dante) cards are expected. A dedicated USB 2 port and included Wi-Fi LAN adapter lets you control the mixer wirelessly, even without a Mac or Windows PC!
With the SLM64AI mixer you also get the latest version of Presonus’ tightly integrated software bundle, including updated Capture 2.0 recording software, Studio One Artist DAW, and Virtual StudioLive-AI editor/librarian/control software with Smaart Measurement Technology. StudioLive Remote-AI for iPad and QMix -AI for iPhone /iPod touch will both be available free from the Apple App Store.

Products that sense each other, interact and work together via wireless and wired communication, feature 32-bit floating-point DSP and seamlessly integrated software, and run on CPUs far more powerful than competitors’ current audio products—PreSonus has realized this dream with its new Active Integration technology.
Thanks to Active Integration, the SLM64AI digital mixer has 64 times the processing power and an incredible 10,000 times more RAM than the StudioLive 24.4.2. This makes possible the aforementioned extended feature set.
It’s a StudioLive—only more so
A quick look at the Presonus SLM64AI reveals a now-familiar, user-friendly mixing surface. It sports 100mm faders for the 64 channels, 8 subgroups, and main bus. As with all StudioLive mixers, convenient knobs and buttons abound, and all core mixing features are immediately accessible from the mixing surface, without using the LCD, providing an intuitive, analog-like user experience.
The unique Fat Channel section delivers a compressor, limiter, gate/expander, and 4-band fully parametric EQ on every channel, bus, and subgroup, plus a high-pass filter and polarity invert for each channel—not to mention routing, panning, and Scene and setting store and recall.
Select buttons assign the channels, buses, and subgroups to the Fat Channel for processing and routing. There’s a Talkback section, Cue section, and extensive metering. And of course you get aux buses—14 of them—and 32-bit floating-point stereo reverb and delay on dedicated buses—two of each.
View the rear, and you’ll see familiar StudioLive connections, with XLR mic and 1/4 inch inputs and TRS insert points on every channel, along with a wealth of other inputs and outputs. A pair of FireWire ports—FireWire S800, rather than the FireWire 400 ports found on the StudioLive 24.4.2, 16.4.2, and 16.0.2—provides wired networking to a Mac or PC, with options for Thunderbolt and Ethernet (Dante). Plus Stereo S/PDIF digital outputs and analog direct channel outputs on DB25 connectors.
The audio quality of the SLM64AI is first rate. Like all StudioLive models, SLM64AI offers PreSonus’ widely lauded Class A XMAX mic preamps and top-notch converters with 118 dB of dynamic range. Reviewers have raved about the high quality of StudioLive mixers’ dynamics processing, EQ, high-pass filters, and effects.
The big picture
The SLM64AI is a fine choice for those who want to mix medium-sized and large shows and worship services, and it's a great choice for club systems, corporate applications, and educational institutions. And it's the perfect hardware core for a sophisticated project studio.
Here, in one device, are high-headroom XMAX mic preamps, a built-in 48x34 FireWire S800 recording and playback interface, more than 300 signal processors, a big library of DSP effects, 14 aux buses, 4 subgroups, extensive LED metering, mixer save and recall, channel-strip save/recall/copy/paste, talkback, and more.
Build live mixes that glisten with clarity and detail—then record and enhance the performance with the power of SLM64AI. Get creative in the studio. Build mixes, loops, sound effects, and more, then bring them out to your show and mix them live. Process channels using your favorite plug-ins and completely automate your entire performance.
That’s just the start. Control the SLM64AI from your Mac, PC, or iPad. Manage monitor mixes from an iPhone or iPod touch. Tune your system to the room and fix feedback problems with VSL-AI’s integrated Smaart Measurement Technology.
Control your sound your way!
Like all StudioLive-series mixers, the SLM64AI offers convenient, backlit Mute and Solo buttons for every channel, subgroup, and aux bus. But the SLM64AI adds another feature that makes the mutes even more useful: six mute groups with All On and All Off buttons.
Virtual StudioLive-AI: The magic of computer control
Despite its analog-like mixing surface, this is very much a digital console, and it offers features no analog mixer, and few digital boards, can match. The ability to control the StudioLive mixer from a laptop adds tremendous flexibility and convenience—and with the bundled Virtual StudioLive-AI bidirectional control/editor/librarian software, you get it all for free.
Written exclusively for StudioLive mixers, Virtual StudioLive (VSL) provides a complete visual representation of the mixer, allowing you to control the features with a mouse, trackpad, or trackball on a networked Mac or Windows PC. Add third-party VPN software, and you can even control StudioLive mixers over the Internet—ideal for contractors. To get a competing mixer with computer control even close to this complete, you'd have to pay several times as much.
Even better: wireless control!
You’re mixing a live show, and you need to check the sound underneath the balcony—or in the balcony, for that matter. Or you’re sound-checking and want to hear the stage monitors for yourself. If you can’t leave the mixing station, you have to rely on someone else’s ears. If you don’t have a reliable crew, you don’t have a chance.
The SLM64ASI sports an Ethernet port that allows you to connect to a wireless router for wired Ethernet and wireless Wi-Fi networking. In addition, the mixer has a USB 2.0 port that hosts the included USB Wi-Fi LAN adapter, providing wireless networking without a router for situations where a less powerful, ad hoc Wi-Fi connection is sufficient.
In this way, the mixer can be controlled from a laptop using VSL and from an iPad using StudioLive Remote-AI, which is available free from the Apple App Store. SL Remote-AI is easy to use, provides control of almost every feature of the StudioLive—including Scene changes and Smaart. And it looks and feels like an iPad app should.
Yet even better: control of monitor mixes from iPhones and iPod touches!
With PreSonus' free QMix -AI, each band member can control their own SLM64AI aux (monitor) mix from an iPhone or iPod touch. QMix lets you adjust a single aux mix per iPhone. Select inputs and levels for your custom monitor mix, and then use the Wheel of Me to get ‘more me’ quickly during performances.
A gigantic console in a small package thanks to the Fat Channel
If SLM64AI 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! That's because each channel has its own studio-grade compressor, limiter, gate/expander, 4-band parametric equalizer, and high-pass filter. In all, Presonus has packed 60 compressors, 60 limiters, 60 gate/expanders, 54 high-pass filters, and more, into one remarkable Fat Channel.
Because the SLM64AI has so much more processing power and blazing-fast RAM than previous StudioLive models, 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 the Alt EQ & Dyn button. In this way, you can experiment with a new sound without having to struggle to re-create your previous settings, and you can edit a setting and then quickly verify that the new version is, in fact, better.
Top Shelf Effects
You get four programmable, 32-bit, stereo DSP effects engines—two of them loaded with reverbs and two armed with delay effects that you can really use. The reverbs are so rich and detailed that you feel like you're there. Delays are precise. Slap echo sounds like old-school tape effects. All 50 preset effects have easy-to-use parameter adjustments, tap tempo, store, recall, and Scene selection for ultimate creative flexibility.
The SLM64AI's 16 31-band graphic equalizers are pre-inserted on each aux mix and on the Main bus so you can fix feedback problems and adjust the frequency balance of your main mix.
Furthermore, with Smaart Measurement Technology, you'll be able to really put StudioLive's 4-band, fully parametric EQs to work improving the sound of your P.A. Precisely identify nasty feedback frequencies. Get your loudspeakers to play nicer with the room they're in. Set the correct subgroup output-delay time for remote speakers. All without having a degree in acoustical engineering.
What was then is now: complete store and recall—instantly
SLM64AI lets you save all of your digital settings for quick setup and recall. Save Scenes that include every setting on the mixer or save just the Fat Channel settings. Copy-and-paste settings across multiple channels. Save individual DSP effects for ultimate ease, speed, and control.
The SLM64AI makes saving and recalling Scenes faster and more convenient than ever thanks to the Fat Channel’s six user-assignable Quick Scene buttons. These buttons 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. You can also use this to have important stored Scenes at your fingertips.
Recording made easy with Capture
If you have a computer with FireWire S800 connection, you have a 34-track digital recorder instantly ready to capture your gig, church service, or presentation. That’s because StudioLive 32.4.2AI features a tightly integrated FireWire 800 interface that delivers up to 48 channels of recording and up to 34 channels of simultaneous playback. Each analog channel on your StudioLive can be set to record either pre- or post-Fat Channel signal processing, delivering total flexibility and power.
Just two mouse clicks engages Capture recording software. When you install it on your laptop, it automatically ‘maps’ to the outputs of the SLM64AI to automatically record all 32 input channels plus the stereo main mix.
Studio One Artist — A serious digital audio workstation
Once you’re recorded studio tracks or a live multi-track performance, it’s time to finish it with effects and a good mix (not to mention editing out that huge burst of feedback during the third song).
Studio One changes the rules of the game with fresh code, innovative drag-and-drop features, advanced MIDI mapping, auto-configuration with your SLM64AI, insanely good audio quality, unlimited tracks and plug-ins per track, and a powerful, inventive Start page. Studio One Artist also comes with a Native Effects 32-bit effects library, complete with dynamics processors, reverbs, modulation effects, amp simulators, and more. And with Studio One's free Nimbit extension, you can immediately start selling your music.
Inside, it's pure PreSonus
Ease of use and powerful features only count if the sound quality is equally impressive. After all, it really comes down to how good those mic preamps are, how clean the signal path is, and how well the algorithms perform.
XMAX Class A preamps deliver more headroom, deeper lows, smoother highs, and a richer overall sound than the preamps found in competing mixers. Ultra-high-headroom, 32-bit floating-point processing is used for all digital mixing. All analog inputs and outputs use the highest quality digital converters available.
Synchronization to your computer is stable and robust, thanks to JetPLL synchronization technology, resulting in great stereo separation and clear, transparent audio.
A Smaart addition to your system
With other mixing systems, you use your eyes, ears, and EQs; wade in; and do the best you can. If you’re a top pro, you know how to read a difficult room and compensate, but the rest of us usually just muddle through—with uncertain results.
Fortunately, it’s a lot easier with StudioLive mixers because the included VSL control/editor/librarian software incorporates Rational Acoustics’ Smaart Measurement Technology. Smaart is a collection of visual audio-measurement tools and techniques for sound-system analysis and optimization that makes tuning the system, squelching feedback, and setting delay times for remote speakers much easier and more precise—and you don’t need an engineering degree to use it.
