PreSonus StudioLive 24.4.2AI

The ease of analog meets the power of digital.

When you’re mixing a live event or have an artist in the studio, you need to be able to work quickly. The StudioLive AI’s familiar, easy-to-use interface keeps all critical controls visible and accessible —not buried in multiple menus or layers. Our design philosophy is simple: One fader for every channel, one output for every bus. This is the power of a surface-driven workflow. But don’t let the analog feel fool you: StudioLive AI mixers offer all of the features you expect in professional-class digital mixers and more.

You’ll never run out of signal processors.

StudioLive AI mixers provide more DSP power than any other mixer in their class. There are no limitations, no shared resources, no figuring out what processing is available where. You have all of the processing available at all times, with no compromises or caveats. The unique Fat Channel provides a compressor, limiter, expander/gate, and parametric EQ on every channel and bus; a highpass filter on each channel; a library of professionally crafted, useful presets; and the ability to save, selectively recall, and A/B-compare processor settings. You also get four effects processors, each with their own dedicated mix bus; a 31-band graphic EQ on every aux mix plus the mains; and 500 ms of delay available to each of the four subgroups.

Computer system requirements:

Below are the minimum computer-system requirements for UC Surface.

Apple iPad

• iPad® Air, iPad mini with Retina display, iPad (4th generation), iPad mini, iPad (3rd generation), or iPad 2
• ​​iOS® 7.03 or later


Mac

• Mac® OS X 10.8 64-bit or later
• Intel® Core™ 2 Duo processor (Intel Core i3 or faster recommended)
• 4 GB RAM (8 GB or more recommended)


Windows

• Windows® 7 x64/x86 SP1, Windows 8 x64/x86, Windows 10 x64/x86
• Intel Core 2 Duo processor (Intel Core i3 or faster recommended)
• 4 GB RAM (8 GB or more recommended)


Mac and Windows Systems

• Wired or wireless network connection
• Internet connection
• For Capture™ and Studio One®:
• FireWire S800 (IEEE 1394b) port
• Internal or external 7200 RPM storage drive highly recommended
• Monitor with 1280x800 resolution
• Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio or MIDI signals.
