Description

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.

Features

  • Very high output (138 dB peak SPL) 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
