Assembly and Manufacturing Plant PA Sound System with 16 TOA Pendant Mount Speakers, Push-to-Talk Paging Microphone and Bluetooth

Inside the Design

This manufacturing and assembly plant PA sound system is designed to provide clear paging, announcements, and background music for large industrial spaces up to 18,000 sq. ft. The system uses high-performance pendant loudspeakers suspended from the ceiling to deliver even sound coverage throughout the facility while maintaining a clean and professional appearance that blends with lighting and building architecture.

At the heart of the system is the TOA BG-2240D 240W mixer power amplifier, which provides reliable amplification and flexible input connectivity for microphones and music sources. Combined with the TOA PM-660U desktop paging microphone and a Pure Resonance Audio BTR1 Bluetooth receiver, the system allows staff to make clear announcements or stream music wirelessly from smartphones, tablets, or computers. This combination creates a dependable communication and audio solution for manufacturing environments where clear messaging is critical.
