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.
