Qsc Llc PL-CA15 Two-way Passive Bi-amp Loudspeaker

Product Description

The QSC LLC PL-CA15 is a two-way passive and bi-amp capable loudspeaker built for professional audio installations and live sound reinforcement applications. Designed around a 15-inch woofer configuration, this cabinet delivers full-range output in a passive crossover mode or can be operated in bi-amp mode for enhanced system control and performance optimization. It is intended for installation by qualified audio systems integrators and professional AV technicians who require reliable, high-output sound reinforcement in demanding environments.

The PL-CA15 is suited for fixed installation and touring applications where a two-way full-range cabinet is required. Bi-amp capability makes it a practical choice for systems where separate amplifier channels are driven to the low-frequency and high-frequency drivers independently, giving the installer greater control over system tuning and headroom. It is typically deployed in venues, performance spaces, and large-scale audio reinforcement setups that demand consistent output and installation flexibility.

Installation Notes

Installation should be performed by a qualified audio systems integrator or professional AV technician familiar with professional loudspeaker wiring and rigging practices. Ensure all amplifiers are powered down before making speaker connections. When operating in bi-amp mode, verify that the internal passive crossover is bypassed per the manufacturer wiring requirements before connecting separate amplifier channels. Follow applicable local codes and rigging safety standards when flying or mounting the cabinet overhead.
