The CX-DA8001 is an intelligent amplifier and speaker line detector designed for professional public address, emergency evacuation, and intelligent broadcasting systems. It combines power amplifier monitoring, automatic amplifier backup switching, and speaker line supervision into one integrated rack-mounted unit. It is suitable for schools, hospitals, hotels, shopping malls, factories, transport facilities, office buildings, and large commercial PA installations where system reliability and fault monitoring are essential.

This device supports 8 main power amplifiers with 1 backup amplifier, automatically switching to the backup amplifier when a main amplifier failure is detected. It also provides 8-zone speaker line monitoring, detecting open circuits, short circuits, and grounding faults. With RS485 communication, real-time status feedback, configurable detection intervals, and modular 1U rack design, the CX-DA8001 provides a reliable solution for intelligent broadcast system protection and maintenance
