About PreSonus StudioLive 312AI 2000-Watt 12inch Three-Way Powered Loudspeaker

Studio-Monitor Accuracy, Superior Imaging, and Intelligibility. Active Integration Loudspeaker

Studio sound. Live performance.

StudioLive® 312AI Active Integration loudspeakers deliver studio-monitor accuracy onstage with unprecedented onboard processing and networking features in a compact form factor. PreSonus® Active Integration technology enables wireless and wired networking control for setup, tuning, and monitoring functions, using an iPad®, a Mac® or Windows®laptop, or both. The StudioLive 312AI provides the best imaging and intelligibility in its class, making it an ideal choice for installations and mobile applications where high fidelity matters.

Three-way coverage with power to spare.

A compact, full-range system with a smooth midrange and rich low end, the PreSonus StudioLive 312AI 2000-watt 12inch three-way powered loudspeaker delivers 3-way coverage, with a 12-inch low-frequency driver and our proprietary 8-inch, CoActual® coaxial speaker for mid- and high-frequency reproduction. These transducers are driven by a hefty 2,000W RMS of triamplified, Class D power, all housed in a compact enclosure. The 312AI is time- and phase-aligned to form a true 4-way system when paired with the StudioLive 18sAI subwoofer, with or without the highpass filter engaged, to provide an optional overlap at 100 Hz for applications that require a little more low-end punch.

The CoActual difference.

PreSonus’ proprietary CoActual 8-inch, horn-loaded coaxial speaker offers a consistent acoustic center and is responsible for high- and mid-frequency reproduction. The single point source provided by this coaxial design offers unique advantages, thanks to the driver’s symmetrical response. The net result is exceptional 3D imaging and a natural listening experience that reveals the subtlest details.

Networkable with Wi-Fi, Ethernet, or Dante.

The PreSonus StudioLive 312AI 2000-watt 12inch three-way powered loudspeaker comes equipped for wireless and wired communications over an Ethernet or Wi-Fi local area network for monitoring and control over custom tuning settings. Better yet, add the SL-Dante-SPK option card to create a Dante network and ditch your analog cables in favor of lightweight CAT5e or CAT6 cables.

You’re in control—here, there, and everywhere.

The StudioLive 312AI features a robust onboard loudspeaker processor that can be accessed and controlled over a standard LAN network. PreSonus’ SL Room Control app for iPad, Mac, and Windows provides rich, easy-to-use system configuration and individual and group control over any StudioLive AI loudspeaker on the network, including alignment delay, parametric EQ, notch filters, group level, and graphic EQ, as well as performance monitoring. SL Room Control makes customizing your speaker system as simple as connecting an Ethernet cable to a wireless router.

Flexible connections and mounting capabilities.

The rear of the PreSonus StudioLive 312AI 2000-watt 12inch three-way powered loudspeaker reveals a combo XLR/TRS line input and an XLR microphone input with an XMAX Class A mic preamplifier and 12V phantom power, as well as an XLR mix output. In addition to the input mixer, you get speaker level-attenuation control. The lightweight plywood enclosure has two ergonomic side handles, interlocking stacking, and M10 fly points. Dual-position pole mounts allow you to mount the speaker atop a stand or subwoofer at 90 degrees or at a 10-degree downward tilt.

Clear, accurate, powerful—and available now.

Whether out on tour or installed in a venue, StudioLive 312AI loudspeakers deliver studio-monitor accuracy at incredibly high SPL, with amazing imaging and intelligibility. With extensive software control and wired and wireless networking, it offers advanced capabilities that go well beyond conventional point-source loudspeakers, yet it’s easy to set up and use.
