The 3Line system is a full-range, powered vertical array sound system that is very compact, easy to move and use for live events or fixed installations. The 3Line System is a combination of the 3Line-C vertical column array, the XT-15A-SUB dual-powered subwoofer with user-adjustable DSP, 3 x combinable loudspeaker mounting poles, a 3L-PSA stand adapter with 2 tilt settings and a speaker cable with Neutrik Speakon plugs. The 3Line-C has 14 drivers that provide a unique combination of wide response, high sensitivity and well-controlled 90 x 10 degrees minimum coverage. The XT-15A-SUB has a 15-inch woofer and two 1,000 watt peak amps onboard to power itself and the 3Line-C. The XT-15A-SUB has a 3-pin, XLR-type line input and also features RS-485 connectors that permit real-time control and monitoring of its DSP parameters via a PC. The Sub also features 4 factory DSP settings for various types of speakers and it has 3 user momery slots so that DSP settings can be saved. Thanks to its broad horizontal dispersion, and wide-range drivers, the 3Line System produces wide smooth frequency response, high intelligibility and prodigious output capability that completely belie its small dimensions and unobtrusive appearance.
