Warehouse and Industrial Space PA Sound System with Octasound SP820A Central Speaker and Bosch Push-to-Talk Paging Microphone

Inside the Design

This warehouse and industrial PA sound system is engineered to deliver clear voice announcements and dependable background audio throughout large open spaces where echoes and ambient noise can reduce intelligibility. At the core of the system is the Octasound SP820A 360° x 180° central speaker, which provides wide, even sound dispersion from a single mounting point—reducing installation time while improving clarity. Paired with the AtlasIED AA240G 240W mixer amplifier and Bosch Plena all-call paging station, this system is ideal for warehouses, industrial storage areas, and distribution facilities requiring reliable paging and music playback. The system is designed to cover approximately 20,000 square feet.

Sound System Features:

• Designed specifically for warehouse and industrial paging applications
• 360° x 180° sound dispersion for wide, even coverage from a single speaker
• Excellent speech intelligibility in large, reverberant environments
• Commercial-grade mixer amplifier with paging and background music support
• All-call paging microphone for clear, prioritized announcements
• Efficient system design minimizes installation time and hardware requirements
