QSC PL-LA8 – 8-in 2-Way Passive/Bi-Amp Installation Line Array, Black

Product Overview

The QSC PL-LA8-BK is a two-way passive 8-inch installation line array loudspeaker engineered for permanent installs requiring controlled vertical coverage and high intelligibility. With a 100x15 degree dispersion pattern and IP54-rated weatherization, this passive line array module serves indoor and covered outdoor applications where consistent SPL across an audience plane is critical. The black (RAL 9011) impact-resistant ABS enclosure supports both passive and bi-amp operation, giving system designers flexibility in amplifier and DSP deployment.

Product Description

The PL-LA8 pairs an 8-inch neodymium LF transducer with a 2-inch voice coil and a 1-inch exit compression driver to deliver a system bandwidth of 69 Hz to 20 kHz (-3 dB). System sensitivity is 101.5 dB (1 W/1 m), with continuous SPL reaching 116 dB in passive mode and 120 dB when bi-amped. The bass reflex enclosure can be ground-stacked up to 4 cabinets or flown up to 14 cabinets when configured with the required PL-LA8-AF array frame. Eight discrete rigging angles from 0.5 to 12 degrees allow precise vertical splay tuning for each deployment. Connectivity includes two Speakon NL4 connectors and a parallel locking 4-pole Euroblock, all housed in an IP65-sealed input cup. At 27.4 lbs, the cabinet balances output density with manageable rigging weight for integrators.

Key Features

• 100x15 Degree Coverage — Wide horizontal dispersion with tight vertical control for even audience coverage.
• Passive or Bi-Amp Operation — Selectable crossover at 1.6 kHz passive or 1.5 kHz bi-amp adapts to varied architectures.
• Neodymium LF Transducer — 8-inch driver with 2-inch voice coil reduces weight while maintaining output for flown arrays.
• Scalable Deployment — Ground-stack up to 4 or fly up to 14 cabinets with the PL-LA8-AF array frame.
• Eight Rigging Angles — Discrete splay settings from 0.5 to 12 degrees enable precise array shaping.
• IP54 Weatherization — Stainless hardware, UV-treated grille, and hydrophobic mesh support covered outdoor use.
• IP65 Sealed Input Cup — Dual Speakon NL4 and parallel Euroblock connectors protected against moisture ingress.

Typical Applications

• House of worship — even vocal and music coverage across sanctuary seating with controlled vertical spill.
• Auditorium — scalable arrays delivering consistent SPL from front rows to rear seating.
• Multi-purpose room — flexible line array coverage for events ranging from speech to live music.
• Commercial meeting space — high intelligibility for presentations and amplified program audio.
• Government space — reliable installed reinforcement for council chambers and assembly halls.

Technical Specifications

Frequently Asked Questions

Does the PL-LA8 require the array frame for deployment?

Yes. The PL-LA8-AF array frame is required for both ground-stack and flown configurations.

Can the PL-LA8 be bi-amped?

Yes. It supports passive operation with a 1.6 kHz crossover or bi-amp operation with a 1.5 kHz crossover for greater system headroom.

How many cabinets can be flown in a single array?

Up to 14 PL-LA8 cabinets can be flown when using the PL-LA8-AF array frame.

Is the PL-LA8 suitable for outdoor installation?

It carries an IP54 rating with an IP65 sealed input cup, stainless hardware, UV-treated grille, and hydrophobic mesh, making it suitable for covered outdoor installs.

What connectors are provided?

Two Speakon NL4 connectors and one parallel locking 4-pole Euroblock, all housed in an IP65 sealed input cup.
