QSC PL-LA12 – 12-Inch 2-Way Passive Installation Line Array

Product Overview

The QSC PL-LA12 is a 12-inch two-way passive installation line array designed for front-of-house reinforcement in small to medium venues such as auditoriums, theaters, and houses of worship. It combines a 12-inch LF transducer with two 1-inch HF compression drivers and the QSC LEAF™ waveguide to deliver high-output, even coverage across wide audience areas. As part of the Q-SYS PL Series, the PL-LA12 is engineered to be driven by CX-Q Series network amplifiers for custom voicings, protection, and telemetry. Its weatherized IP54 ABS enclosure supports both indoor and protected outdoor passive line array deployments.

Product Description

The PL-LA12 scales from compact distributed systems to full flown arrays, with integrated rigging that supports ground stacking of up to three modules and flying of up to 12 modules per array using the PL-LA12-AF array frame. The same array frame allows the PL-LA12 to be flown together with the PL-SUB18 subwoofer for full-range coverage, including configurations of three subwoofers above ten line array modules. Because any change to array size or curvature shifts the tonal response, CX-Q network amplifiers apply custom voicings and filter sets automatically to keep the system balanced. The passive design presents an 8-ohm nominal load with speakON NL4 and Euroblock connectors. Pair it with the QSC PL-SUB18 installation subwoofer for low-frequency extension, or choose the smaller QSC PL-LA8 line array for tighter spaces.

Frequently Asked Questions

Is the PL-LA12 powered or passive? It is a passive loudspeaker requiring external amplification. QSC recommends CX-Q Series network amplifiers (up to four per channel on the CX-Q 8K4, up to two per channel on the CX-Q 4K4).

Can I fly subwoofers with the line array? Yes. Using the PL-LA12-AF array frame, PL-SUB18 subwoofers can be flown with PL-LA12 modules for full-range coverage. Consult the QSC user manual for factor-of-safety information.

How many modules can be flown? Up to 12 PL-LA12 modules per array, or up to three PL-SUB18 plus ten PL-LA12 modules on the PL-LA12-AF frame.

Is it suitable for outdoor installation? The IP54-rated ABS enclosure with treated grille and sealed input cup supports indoor and protected outdoor locations.
