1. Main/Backup Amplifier Switching

With main and backup amplifier switching, the public address system can guarantee the normal operation of horn speakers in a military parade or emergency. MP9821M can automatically detect the failure of the audio amplifier and switch between the “main amplifier”and the “backup amplifier”. With 4 identical independent channels, it can realize automatic detection and switching of the main/backup amplifier through each channel, or manual switching.

2. Terminal Devices

The terminal speaker used at the parade site is DSP3008A, an outdoor waterproof speaker. With a wide frequency response of 120Hz-18kHz and maximum sound pressure level of 124dB, as well as farther transmission distance, it can fully meet the requirements of the parade site. As the driver has excellent shock absorption effect, it can output clear and loud sound. With long service life and high quality, it can ensure long-term durability, and will never be deformed. Also, it is equipped with a three-point mounting bracket.

3. Lightning Protection

The broadcast system can be used outdoors as it can protect the field equipment from lightning when it encounters thunderstorm. With lightning protection, over voltage protection and leakage protection, as well as 4-channel input and output control, MP9824L will automatically cut off the output of all audio sources controlled by the unit to avoid loss when it is in the fault protection state.
