INSTALL Retail Mall Audio With PA Over riding system ( approval )

The DSPPA MP120UB is a 120W Mini Digital Mixer Amplifier equipped with USB, FM, and Bluetooth capabilities. It features multiple inputs and outputs, including two MIC inputs, two line inputs, and one line output. It also supports EMC inputs, which are crucial for emergency situations like fire alarms. The amplifier provides both constant voltage (70V/100V) and constant resistance (4-16Ω) outputs, making it versatile for various setups.

In retail malls, fire alarm testing often involves integrating the amplifier with the emergency broadcast system. This ensures that in case of a fire, the system can automatically prioritize emergency messages over regular background music or announcements. The MP120UB's priority function is particularly useful here, as it allows emergency signals to override other inputs.

For fire alarm testing in retail malls, the system must comply with safety standards like EN54-16/24, ensuring reliability and durability. The integration typically involves linking the amplifier with fire alarm triggers, which can activate emergency broadcasts across the mall's public address system.
