2.1Overview
Matrixcontrollercanrealizebusinessbroadcastingandfirealarmlinkageemergencybroadcasting
by supporting Peering Frame and fire alarm. It is a Public Address system and fire protection
linkage alarmsystemsuitable forlargepublic places such as railways,business offices, factories,
schools,hospitals,shoppingmalls,entertainmentplaces,etc.
MatrixController:
(1) Standard 2U rack-mounted design, 4.3-inch true color LCD screen, which can display
informationsuchasworkingstatusandequipmentparameters.
(2) Support emergency broadcast function, can receive fire alarm linkage alarm signal from fire
alarmcontrollerforemergencybroadcast.
(3)Supportlocalbroadcast,networkbroadcast,schedulebroadcast,etc.;canrealizemulti-receiver
andmulti-sourcebroadcast,schedulebroadcast,controlinputtriggersourcebroadcastandother
functions.
(4)Supportzonecontrol,youcanmanuallyselecttheaudiosourceandzones,supportthecontrol
oflocalaudioinputplaybacktoanyaudiooutput,andcanplayanyaudiosourceinanyzones.
(5) Optional hand-held microphone can be used for general manual broadcasting and fire
emergencybroadcasting.
(6)Built-inmonitorspeakers,whichcanmonitortheaudiosourceandzone’saudio.
(7)Withautomaticnoisecontrolfunction,itcanmonitortheexternalenvironmentalnoiseofeach
outputchannelinrealtime,automaticallyadjusttheoutputsoundpressurelevel,andimprovethe
clarityofthesound.
(8)Withself-checkfunction,theself-checkisrealizedthroughthe"self-check"buttononthepanel.
During the self-check process, all the indicators on the front panel are always on (multi-color
indicatorsalternatelydisplaydifferentcolors),andthefaultindicationbuzzersoundscontinuously.
During the self-check process,all devices directly connected to thematrix controller execute the
self-checkfunction.
(9)Withfaultdetectionfunction,itcan detecttheopencircuit,short circuit, groundfault,power
amplifierfaultandpowersupplyfaultofthehorncircuit.
(10) It has the function of power amplifier reverse backup. When a power amplifier failure is
detected,itcanautomaticallyswitchtothebackuppoweramplifiertoensurethatthebroadcastis
notinterrupted.
(11) Equipped with dual network ports, supporting network redundancy backup, one network
interruption,canautomaticallyswitchtoanothernetwork.
(12) With CPU OFF function, when the device crashes or the network is paralyzed, the CPU OFF
functioncanbeturnedontorealizethewholeareabroadcasting.

PeeringFrame:
(1) The standard 4U rack design is used to supply power to the digital power amplifier module
installedinthechassis.
(2) Provide 4 channels digital power amplifier module slot + 1 channel standby digital power
