A New Generation of QSC Line Arrays: LA108 / LA112 in the L Class Range
The QSC L Class LA112 continues the tradition of compact line array systems designed to combine audio quality, ease of deployment, and scalability. Developed alongside the LA108, it has a clear goal: to enable "ready-to-play" deployment in small configurations, while remaining perfectly comfortable in more ambitious systems, whether in audiovisual production or fixed installations.
This range philosophy is reflected in a modular approach: the array is composed according to the venue, audience, and desired coverage, while maintaining sonic coherence within the same system.
Intended Uses and Users
The LA112 is designed for contexts where a front-of-house speaker is expected to be powerful, quick to deploy, and precise: live performances, demanding DJ sets, corporate events, places of worship, theaters, clubs, multipurpose rooms, and networked audiovisual installations.
It is suitable for both solo artists and small technical teams (thanks to intuitive deployment mechanics) as well as installers and production companies seeking a modern, interoperable, and optimizable solution, especially when an IP audio network and monitoring are central to the project.

Questions frequently asked
What power and SPL level does the QSC L Class LA112 deliver?
The built-in amplification provides 1,200 W RMS and 2,400 W peak, for a maximum SPL of 136 dB. The 2-way configuration combines a 12-inch speaker with a 1.75-inch high-frequency driver.
What coverage does this line array speaker offer?
The stated dispersion is 90° horizontal and 15° vertical. The QSC LEAF waveguide aims for even coverage within the array.
Can the LA112 be used with Dante and Q-SYS?
Dante integration allows audio transport over IP via EtherCON connections. Control and monitoring can be integrated into Q-SYS, while the SysNav app is used to configure and monitor the system.
Can the LA112 be quickly rigged in an array?
The RapidDeploy rigging system is designed for deployments without tools or additional hardware. Short, medium, and long-throw adjustments allow adapting the array's orientation.
What is the weight and what connections does this speaker have?
Weighing 21.4 kg and measuring 392 × 630 × 417 mm, this speaker features two carrying handles. Inputs and outputs include XLR, powerCON, and EtherCON. A 35 mm pole mount is also provided.
