The QSC WP-001239-01 is a specialized right-side rigging assembly engineered exclusively for the QSC KLA12 active line array loudspeaker. This precision-made hardware kit is a critical component for deploying the KLA12 in flown array configurations, enabling safe and secure overhead suspension in live sound and installation applications. The assembly is designed to attach to the integrated rigging points on the right side of the KLA12 cabinet, interfacing with the corresponding left-side assembly on an adjacent cabinet to form a mechanically interlocked column. Its primary function is to manage the substantial physical forces involved in flying multiple loudspeakers, ensuring precise angular splay control while maintaining absolute structural integrity to prevent accidental disconnection.

Constructed from high-strength, forged steel and featuring robust load-rated hardware, the rigging assembly is built to meet rigorous safety standards for overhead loads. The design incorporates a positive-locking mechanism that provides both an audible and tactile confirmation when cabinets are properly joined, a vital feature for ensuring safety during array assembly. The hardware allows for a defined range of vertical splay angles between cabinets, which is essential for acoustic engineers to shape the vertical coverage pattern of the array to suit the venue's specific requirements. Secondary safety attachment points are integrated into the design, allowing for the use of redundant safety cables or straps as an additional failsafe measure.

For audio professionals utilizing the QSC KLA12 system, this right rigging assembly is an indispensable accessory for any flown application. It transforms the compact powered loudspeaker into a scalable array element, facilitating quick setup and strike while guaranteeing the safety of performers, crew, and audience below. By providing manufacturer-approved, engineered hardware, it ensures that the acoustic performance of the KLA12 array is realized with the correct physical alignment and with the utmost regard for reliability and safety.
