MAG2120II/MAG2140II Intelligent Audio Matrix PA System Functional Features and Applications

I.Solution Description

DSPPA Intelligent public address system is a set of embedded public address system with powerful digital broadcasting matrix system function and modular construction, which has changed the manual control mode of the traditional public address system, and the whole process is controlled, managed and played by the computer. The system also makes use of the latest modern technology, fully considering the development needs. It not only reserves various interfaces to facilitate the expansion and upgrade of the system, but also can switch various audio sources and various playback areas to achieve the effect of playing different audio sources in different playback areas.

II.Solution Highlight Functions

MAG2120II (MAG2140II) is a powerful intelligent PA system center. It is an 8x20 (8x40) audio matrix. It has all the functions needed for a normal PA project, such as background music playing, programmed audio playing, remote paging, fire alarm, etc.

It supports 8 audio inputs and 20 (40) audio outputs. The audio sources support AUX inputs, USB, Tuner, built-in memory, etc. The system supports remote paging and remote computer remote control.

IV.System Functions

● Playing Background Music and Timing Function
According to the needs of factory management, the system can be preset to play a timed playlist for one day or one week and play the commute ring regularly; It can manually and automatically control the switch of each zone of the system and manually control the volume of the system. The system can automatically switch on and off at regular intervals, which not only saves energy but also prolongs the service life of the equipment.
● Information Dissemination
Using the background music broadcasting system to broadcasting the latest situation of factory, etc.
● Broadcasting Notice at the Management Office
Using the local broadcast microphone and remote paging microphone to broadcasting notice and people finder, etc.
● Zone Broadcasting Function
The host (intelligent control center) is not only equipped with a 7-inch touch screen, which is separated from the traditional physical button operation, and the operation is simple and convenient. It has 8 audio inputs and 20 (40) audio outputs zone interface, which can be scheduled broadcast, manual zone broadcast or whole area broadcast.
● Voice Broadcasting
The public address system is equipped with a paging microphone MP9810RII, which is mainly used for the management personnel to give friendly reminders and warm greetings in different functional areas during normal work time and rest hours. In emergencies, it can be used as a guide for refuge, orderly transfer, etc. It can be operated quickly and effectively through paging calls according to the on-site situation.
● Adjacent Floor Emergency Broadcasting
When an emergency occurs, the emergency broadcast information can be played in time, and other functions of the public broadcasting system (such as background music, general broadcast) will be suspended, which can quickly evacuate into the group and guide the evacuation direction of personnel.
● Fire Broadcasting
The host MAG2120II/MAG2140 has a 20/40-way fire trigger interface, which can be linked with the fire system. When an emergency such as a fire occurs in the area where the floor is located, a certain zone of the host receives an alarm signal from the fire protection system, then the zone will trigger a preset alarm voice (alarm voice can use the built-in alarm voice of the host, or can be recorded in advance and input externally through the MP9815E). It can prompt personnel to do evacuation work and can command evacuation through the host's own emergency microphone or paging microphone MP9810RII to minimize the damage caused by the accident.
● Telephone Broadcasting
The leader in the company can use mobile phones, landline telephone and other telephones to broadcast and issue notices to factories remotely.
