PreSonus StudioLive 24.4.2
24x4x2 Digital Mixer, QMix Compatible

The StudioLive™ features signal-processing power on every channel, easy store and recall of every setting, and the ability to record it all with just two mouse clicks.  StudioLive is not simply a mixer, it’s a rapidly growing family of state-of-the-art, integrated hardware-software mixing and recording systems that deliver the features you need for live sound, live recording, and studio recording.
The StudioLive 24.4.2 is a great choice for those who want to mix small to medium-sized shows and worship services, and it’s a great choice for club systems, corporate applications, and educational institutions. It's also perfect for us in a project studio.

It uses high-headroom XMAX™ microphone preamplifiers, built-in FireWire recording and playback interface, more than 90 signal processors, a big library of DSP effects, 10 aux buses, 4 subgroups, extensive LED metering, mixer save and recall, channel-strip save/recall/copy/paste, talkback, and more. Even with this amount of controls and features, it’s compact and easy to transport.

The ease of analog meets the power of digital.

All critical controls are visible and accessible—not buried inside multiple menus.

Real hardware Mute and Solo buttons, trim controls, and clearly labeled, individual knobs for the parametric EQ and dynamics processing. The master section—complete with Talkback, Monitor, Cue, and a choice of headphone sources—looks just like the master section on an analog board but with far more power and flexibility. Aux sends have their own controls. Every channel has a big, bright meter display.

A gigantic console in a small package thanks to the Fat Channel.

If StudioLive 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, 4-band parametric equalizer, and high-pass filter. In all:  43 compressors, 43 limiters, 43 gates, 24 high-pass filters, and more, are in one Fat Channel.

Engaged by pressing any Select button, the StudioLive 24.4.2’s Fat Channel features extensive EQ and dynamics for every input channel, every aux output (including the two internal FX buses), every subgroup output, and the main outputs.

To let you get the most from all of this processing power without descending into menu purgatory, we designed the Fat Channel with clearly labeled physical knobs; an ingenious, multi-function, 16-ladder LED display; an in-your-face Selected Channel display; and even a separate horizontal pan display. It’s easy to instantly access any function and get clear, visible feedback.

Not just effects. Effects like that of a stand-alone processor.

Two programmable, 32-bit, stereo DSP effects engines, loaded with 50 reverbs, delays, and time-based 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 effects have easy-to-use parameter adjustment, tap tempo, store, recall, and Scene selection for ultimate creative flexibility.

The StudioLive 24.4.2’s 4 dual, 31-band graphic equalizers can be applied to the main, subgroup, and aux outputs so you can compensate for room acoustics, speaker response, and much more.

All of these features add up to a lot of settings to remember and reset at every performance. That’s where the power of digital comes in: StudioLive 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.

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 the StudioLive 24.4.2.

An AutoStore feature regularly saves your current settings in case the power fails.

Recording made easy.

Connect to a computer with 6-pin FireWire for 26-track digital recorder instantly ready to capture your gig, church service, or presentation. Just two mouse clicks engages Capture™ recording software. Studio One Artist™ digital audio workstation lets you edit and enhance to the content.

StudioLive 24.4.2 features a tightly integrated FireWire interface that delivers up to 32 channels of recording and up to 26 channels of simultaneous playback. Each FireWire recording channel can be set to record either pre- or post-Fat Channel signal processing, delivering total flexibility and power.

Inside, it’s pure PreSonus.

XMAX™ Class A preamplifiers 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.

StudioLive expands with your input needs.

Need more than 24 channels for mixing live shows and don’t need to record? Daisy-chain two StudioLive 24.4.2s via their FireWire ports to get up to 48 input channels and 8 submix buses. If you need more than 24 channels for recording, and you don’t need a full channel strip for the additional inputs, you can daisy-chain a StudioLive 24.4.2 with a PreSonus FireStudio Project, FireStudio Tube, or FireStudio Mobile interface. It could not be simpler.

Free Universal Control 1.6 and StudioLive Remote 1.3 for iPad updates

With Universal Control 1.6, Rational Acoustics' Smaart™ real-time analysis features have been integrated into Virtual StudioLive (VSL), which is part of Universal Control.  Virtual StudioLive now offers both Smaart Spectra™ time frequency spectrograph and real-time analyzer (RTA) views, which are superimposed over each graphic EQ.

The Smaart Spectra spectrograph display can help to precisely identify nasty feedback frequencies, enabling even less-experienced users to easily tune P.A. speakers to the room.  Smaart Spectra graphs a continuous series of spectrum measurements, showing frequency on one axis, time on another, and amplitude indicated by colors.  This makes it very useful for quickly identifying feedback frequencies, which can be easily addressed using StudioLive graphic EQs.

Universal Control 1.6 adds other useful features, as well.  You can now control Talkback on/off and routing with VSL.  Version 1.6 also adds support for the new StudioLive Remote 1.3 update.

Universal Control 1.6 updates the Windows and Mac drivers for all StudioLive-series mixers products and all FireStudio™-series interfaces except for the original FireStudio (26x26).  This update improves performance, especially on Windows systems.  Note that Universal Control 1.6 requires a firmware update to StudioLive mixers.

PreSonus has simultaneously released StudioLive Remote 1.3 for iPad.  This version of the company's wireless mixer-control app adds Talkback on/off and routing assignments and enables Scene recall for hard-disk-based Scenes (but not for Scenes held in mixer memory).

Universal Control 1.6 is a free update and can be downloaded from the Technical Support section of the PreSonus Web site. StudioLive Remote 1.3 is a free download from the Apple App Store.

Virtual StudioLive Software for Mac and Windows

Virtual StudioLive™ provides bidirectional control of all StudioLive-series digital mixers.  Written exclusively for StudioLive mixers, and accessed as the StudioLive's Device window in the free PreSonus Universal Control application, VSL provides a complete visual representation of the mixer, enabling you to see and control the most-used mixer parameters onscreen, including channel, subgroup, aux send, and main levels; mutes and solos; and Fat Channel, effects, and graphic EQ settings.

Controlling your StudioLive with VSL is as easy as drag-and-drop.  You can load Fat Channel settings by simply dragging them onto the channel or mixer overview, either as a complete channel strip, or as individual gate, compressor, and EQ presets.  Want to just load the EQ settings onto Channel 1?  Just select the Fat Channel for Channel 1 and drag a preset to the visual representation of the EQ.  You can mix and match settings to your heart's content.  Or apply a new Scene to the whole mixer by dragging it onto VSL's virtual mixing surface from a browser list that you see at all times.

Through VSL, you can back up all of the Scenes and presets stored on your StudioLive.  Save virtually unlimited Scenes and settings and name them and rearrange them in the browser.  These stored settings can be loaded from disk or sent to, and stored internally on, the StudioLive.  You can even drag presets out of the browser and email, IM, or disk-swap them with other StudioLive owners.

Since the control is bidirectional, fader moves and parameter changes made on the StudioLive are re?ected in VSL in real time.  So, for example, you can set up the StudioLive the way you want it and then save your Scene or other presets in VSL.

VSL also combines with StudioLive Remote to provide mixer control from an Apple iPad® and combines with QMix to enable you to control StudioLive aux mixes from an Apple iPhone® or iPod touch®.

As powerful as VSL is, PreSonus is constantly adding more features.  They have recently begun to incorporate Rational Acoustics' highly regarded Smaart Measurement Technology™ directly into Virtual StudioLive, beginning with Smaart Spectrum™ in Universal Control 1.6, available in PreSonus' website's Technical Support section.

NOTE: For more information on Smaart Measurement Technology™, please view the attached brochure, found under the "Documents" tab.
