Features Includes: PreSonus StudioLive 315AI Active Loudspeaker Pair USA Power Plugs & Cable Ties Wireless USB Adapter User Manual Description Product Description The StudioLive 315AI is perfect for large venues and bands that need full-range speakers with plenty of low end. The StudioLive 315AI provides 3-way coverage, with a 15-inch speaker for low frequencies and a custom-designed, 8-inch coaxial speaker with a 1.75-inch titanium compression driver to reproduce the mid and high frequencies. These transducers are driven by a hefty 2,000W RMS of triamplified, Class D power. The rear of the 315AI reveals a combo XLR/TRS line input and an XLR microphone input with an XMAXTM 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 and USB and Ethercon connections. The lightweight plywood enclosure is pole-mountable and has two ergonomic side handles, interlocking stacking, and M10 fly points. Four operation modes allow the user to choose DSP presets for their application, such as MP3 playback, live performance, or stage monitoring-or create a custom preset using SL Room Control software for Mac, Windows, and iPad.
