QSC PL-LA8 – 8-Inch 2-Way Passive Installation Line Array

Product Overview

The QSC PL-LA8 is an 8-inch two-way passive installation line array built for front-of-house sound reinforcement in small to medium venues. Part of QSC's PL Series of performance loudspeakers, it pairs an 8-inch LF transducer and a 1-inch HF compression driver with the QSC LEAF™ waveguide for smooth, controlled coverage. Designed for the Q-SYS ecosystem, the PL-LA8 is engineered to be driven by CX-Q Series network amplifiers for custom voicings, system protection, and telemetry. Its weatherized IP54 ABS enclosure makes it suitable for indoor and protected outdoor passive line array installations.

Product Description

The PL-LA8 delivers a high-performance, scalable line array solution for auditoriums, houses of worship, and multi-purpose spaces. Integrated rigging hardware supports ground stacking of up to four modules and flying of up to 14 modules per array when used with the PL-LA8-AF array frame, with eight preset inter-cabinet splay angles for precise vertical coverage shaping. Because adding boxes or changing array curvature alters the tonal response, QSC's CX-Q amplifiers apply custom voicings and filter sets automatically to simplify deployment. The passive design accepts standard speakON NL4 and Euroblock connections and presents an 8-ohm nominal load. For larger rooms, step up to the QSC PL-LA12 12-inch line array, and complete the rig with the PL-LA8-AF array frame.

Frequently Asked Questions

Is the PL-LA8 powered or passive? The PL-LA8 is a passive loudspeaker and requires 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).

How many PL-LA8 modules can I fly together? Up to 14 modules can be flown per array using the PL-LA8-AF array frame, and up to four can be ground stacked. Consult the QSC user manual for factor-of-safety information.

Can it be installed outdoors? The enclosure carries an IP54 weatherization rating with a treated grille and sealed input cup, making it suitable for indoor and protected outdoor locations.

Does it integrate with Q-SYS? Yes. When driven by CX-Q amplifiers it gains custom loudspeaker voicings, system protection, and telemetry managed in Q-SYS Designer and monitored remotely via Q-SYS Reflect Enterprise Manager.
