Description

QSC LS118 is an active subwoofer with a 4000W class D amplifier, its frequency range covers from (-10dB) 35Hz to 111Hz and has an SPL peak of 138dB. On the back, we find a display with related controls to access DSP functions, an analog input and an analog thru output on XLR connectors, 2 RJ45 EtherCON ports, and 2 PowerCON TRUE1s.

QSC LS118 is the subwoofer from the L Class series, powerful, high-performance, and versatile; thanks to the various analog and digital connection possibilities, it is perfect for both simple plug-and-play installations and more complex network configurations or fixed installations. It has two M20 inserts for vertical or horizontal pole mounting of QSC LA 108 and LA112 units and 8 additional M10 inserts where eye bolts can be screwed in for suspended installations.

This model features QSC Acoustic Linear Phase (ALP) technology for consistent phase response across the entire listening area, analog connection points for daisy-chaining, and RJ45 ports for using the QSC LS118 in Dante networks and for remote control with the QSC SysNav app. With two or more units, a cardioid configuration can be easily created to focus energy on the audience and minimize energy radiated to the rear and sides of the system.

Main features of QSC LS118

    
• High output level (138dBSPL peak)
    
• Specially designed 18" long-excursion cone
    
• Acoustic Linear Phase (ALP) ensures perfect phase coherence with other QSC speakers and a uniform listening experience throughout the venue
    
• 4000W peak high-efficiency Class D amplifier
    
• The QSC SysNav app allows the user to design, configure, control, monitor, and apply signal processing to individual subwoofers, entire arrays, or groups of both
    
• Support for the Dante audio-over-IP protocol for interoperability with other audio equipment and seamless control and monitoring integration into the Q-SYS ecosystem via Q-SYS Inventory Extensions
    
• Omnidirectional and cardioid modes (the latter requires a minimum of 2 units)
    
• DEEP mode for low-frequency reinforcement
    
• Robust wooden cabinet with polyurea coating for increased durability even with heavy use
    
• 4 durable and silent swivel casters
