QSC LA112 – 2400W 12-Inch Active Line Array Loudspeaker

Product Overview

The QSC LA112 is a 12-inch two-way active line array loudspeaker for high-output sound reinforcement in larger venues and touring systems. A 2400 W peak Class D amplifier drives a neodymium 12-inch woofer and dual 1.75-inch compression drivers to a 136 dB peak SPL, and the QSC LEAF waveguide delivers defined 90-degree-by-15-degree coverage with strong throw. Onboard QSC AWARE array recognition, QSC SysNav control, and Dante audio-over-IP make the LA112 a networked line array suited to performing arts centers, houses of worship, and convention spaces.

Product Description

The LA112 combines a lightweight 12-inch woofer and dual 1.75-inch compression drivers with system intelligence for fast, single-operator deployment. The 2400 W Class D module (1600 W LF / 800 W HF) uses power factor correction for low AC draw, and QSC RapidDeploy rigging provides tool-free splay-angle setup. Onboard QSC AWARE reports array configuration through the 2.4-inch full-color Rear User Interface or the QSC SysNav app, including AIM array-coverage modeling, while dual etherCON ports carry Dante audio and SysNav control into the Q-SYS Ecosystem via Q-SYS Inventory Extensions.

The LA112 can be flown in arrays of up to six with the dedicated array frame, ground-stacked up to three over a single LS118 subwoofer, or pole-mounted up to two. For smaller rooms or as down-fill, see the QSC LA108 8-inch line array, extend low end with the QSC LS118 powered subwoofer, or add the LA112 array frame for flown systems.

Frequently Asked Questions

How does the LA112 compare to the LA108? The LA112 uses a larger 12-inch woofer and dual compression drivers for higher output (136 dB peak) and a 90-degree horizontal pattern, suited to larger venues; the LA108 is an 8-inch model with a 100-degree pattern for smaller spaces.

Can the LA112 be ground-stacked? Yes. Up to three LA112 can be ground-stacked over a single LS118 subwoofer, or up to two can be pole-mounted.

Does it integrate with Dante and Q-SYS? Yes. Dual etherCON ports carry Dante audio-over-IP and QSC SysNav control, with integration into the Q-SYS Ecosystem via Q-SYS Inventory Extensions.

What warranty applies? QSC provides a 6-year warranty when the product is registered within 30 days of purchase, subject to QSC warranty terms. For details or system design help, contact Creation Networks support.
