L Class represents the next-generation of advanced, intelligent, active loudspeakers for mobile and fixed entertainment applications. The LA112 is a next-generation, intelligent, active line array loudspeaker featuring a brilliant combination of leading-edge innovation, refined engineering and unparalleled ease of use in easy-to-deploy packages. Delivering extraordinary audio experiences and exceptional performance via system intelligence and premium components, both products were developed thoroughly and rigorously with sound quality, simplicity and expandability in mind. The remarkable result of a deep understanding of customer needs and application requirements, LA112 loudspeakers are easy to configure and deploy for applications ranging from simple, portable, plug-and-play setups, to demanding, networked, high-tech AV productions and fixed installations. Solo entertainers, installers and production companies will value their intuitive splay angle adjustment and array optimization, as well as their flexible interoperability with networked audio systems (Dante).

Technical innovations abound, including the proprietary QSC LEAF (LengthEqualized Acoustic Flare) waveguide, QSC Acoustic Linear Phase (ALP) design and the ergonomically designed, single operator QSC RapidDeploy rigging system coupled with onboard QSC AWARE (Automatic Wireless Array Recognition) system intelligence. Deployed using dedicated array frames, ground-stacked (array frames combined with optional sub-stack adapters), or mounted using loudspeaker stands/poles, LA112 loudspeakers also feature daisy-chain connections for analog, digital audio as well as for AC power (PowerCON TRUE1). Each loudspeaker is backed by an industry-best global 6-Year Extended Warranty, with product registration.

QSC LA112 12" Two-Way Active Line Array Loudspeaker Features:

  • Purpose-designed, lightweight neodymium transducers deliver high, undistorted SPL (136 dB peak).
  • Energy efficient Class D amplifier modules (2400 W peak power) with Power Factor Correction and extremely low AC consumption.
  • Innovative QSC LEAF (Length-Equalized Acoustic Flare) waveguide provides defined, uniform coverage and exceptional throw.
  • Intuitive, single operator QSC RapidDeploy rigging technology with short, medium and long-throw options, guarantees fast deployment without tools or additional hardware.
  • Onboard QSC AWARE (Automatic Wireless Array Recognition) system intelligence communicates essential setup information to the user via any loudspeaker's Rear User Interface (RUI) or QSC SysNav App.
  • QSC SysNav (System Navigator) App allows the user to easily design, configure, control, monitor and apply signal processing to individual loudspeakers, full arrays or groupings of both.
  • The AIM (Array Installation Modeling) prediction tool lets the user visualize array coverage by positioning virtual loudspeakers and arrays in a scaled, graphical model of a venue or installation space.
  • Network solution includes digital audio-over-IP (Dante) for interoperability with other audio equipment and seamless control and monitoring integration into the Q-SYS Ecosystem via Q-SYS Inventory Extensions.
  • Acoustic Linear Phase (ALP) design provides complementary coherence between QSC loudspeakers deployed in the same audio system delivering a uniform listening experience across the entire venue.
  • Complemented by LS118, networked, single 18-inch active subwoofer.
  • Flown (up to six units with array frame), ground- stacked (up to three LA112 over a single LS118 subwoofer) or loudspeaker stand/pole mounting (up to two LA112) deployment options.
  • Industry-best global 6-Year Extended Warranty with product registration.

L Class represents the next-generation of advanced, intelligent active loudspeakers for mobile and fixed entertainment applications. The LS118 is a next-generation, intelligent, active subwoofer featuring a brilliant combination of leading-edge innovation, refined engineering and unparalleled ease of use in an easy-to-deploy package. Delivering extraordinary audio experiences and exceptional performance via system intelligence and premium components, the LS118 is the result of a deep understanding of customer needs and application requirements. The LS118 is easy to configure and deploy for applications ranging from simple, portable, plug-and-play setups, to demanding, networked, high-tech AV productions and fixed installations.

Featuring QSC Acoustic Linear Phase (ALP) design, which permits effortless combination and coherent deployment of QSC loudspeakers within the same sound system, the LS118 also provides daisy-chain connections for analog, networked digital audio (Dante) and AC power (PowerCON TRUE1). Two or more LS118 can be configured in a cardioid arrangement, maximizing low frequency output in front while minimizing unwanted energy around the sides and rear of the system. Together with the LA108 or LA112 active line array loudspeakers, the LS118 can be deployed with either an array frame/ground-stack adapter or using loudspeaker poles in both horizontal and vertical orientations. The LS118 is backed by an industry-best global 6-Year Extended Warranty, with product registration.

QSC LS118 18" Subwoofer Features:

  • Very high SPL output (136 dB peak) with impressive low frequency performance.
  • Purpose-designed, 18-inch (460 mm) long excursion direct radiating driver.
  • Energy-efficient, 3600 W peak power Class D amplifier module with Power Factor Correction and extremely low AC consumption.
  • Acoustic Linear Phase (ALP) design provides complementary coherence between QSC loudspeakers deployed in the same audio system delivering a uniform listening experience across the entire venue.
  • QSC SysNav (System Navigator) App allows the user to easily design, configure, control, monitor and apply signal processing to individual subwoofers, full arrays or groupings of both.
  • Network solution includes digital audio-over-IP (Dante) for interoperability with other audio equipment and seamless control and monitoring integration into the Q-SYS Ecosystem via Q-SYS Inventory Extensions.
  • Omni-directional or cardioid radiation modes (cardioid setup requires min. 2 units).
  • Selectable DEEP mode for extremely low frequency extension.
  • Rugged wooden enclosure with Polyurea coating for lasting durability.
  • Four low-noise, heavy-duty casters.
  • Vertical or horizontal deployments (M20 threaded pole receivers) combined with array frames and stack adapters or loudspeaker poles.
  • Complemented by LA108 and LA112 active line array loudspeakers.
  • Industry-best global 6-Year Extended Warranty with product registration.
