2. PRODUCT INTRODUCTION
2.1 Overview
Matrix controller can realize business broadcasting and fire alarm linkage emergency broadcasting
by supporting Peering Frame and fire alarm. It is a Public Address system and fire protection
linkage alarm system suitable for large public places such as railways, business offices, factories,
schools, hospitals, shopping malls, entertainment places, etc.
Matrix Controller:
(1) Standard 2U rack-mounted design, 4.3-inch true color LCD screen, which can display
information such as working status and equipment parameters.
(2) Support emergency broadcast function, can receive fire alarm linkage alarm signal from fire
alarm controller for emergency broadcast.
(3) Support local broadcast, network broadcast, schedule broadcast, etc.; can realize multi-receiver
and multi-source broadcast, schedule broadcast, control input trigger source broadcast and other
functions.
(4) Support zone control, you can manually select the audio source and zones, support the control
of local audio input playback to any audio output, and can play any audio source in any zones.
(5) Optional hand-held microphone can be used for general manual broadcasting and fire
emergency broadcasting.
(6) Built-in monitor speakers, which can monitor the audio source and zone's audio.
(7) With automatic noise control function, it can monitor the external environmental noise of each
output channel in real time, automatically adjust the output sound pressure level, and improve the
clarity of the sound.
(8) With self-check function, the self-check is realized through the "self-check" button on the panel.
During the self-check process, all the indicators on the front panel are always on (multi-color
indicators alternately display different colors), and the fault indication buzzer sounds continuously.
During the self-check process, all devices directly connected to the matrix controller execute the
self-check function.
(9) With fault detection function, it can detect the open circuit, short circuit, ground fault, power
amplifier fault and power supply fault of the horn circuit.
(10) It has the function of power amplifier reverse backup. When a power amplifier failure is
detected, it can automatically switch to the backup power amplifier to ensure that the broadcast is
not interrupted.
(11) Equipped with dual network ports, supporting network redundancy backup, one network
interruption, can automatically switch to another network.
(12) With CPU OFF function, when the device crashes or the network is paralyzed, the CPU OFF
function can be turned on to realize the whole area broadcasting.
(13) Support redundancy for power supply, usually from power supply A, when the power supply A
fails, it can automatically switch to the power supply B; when the power supply A returns to normal,
it will automatically return to the power supply A.
Peering Frame:
(1) The standard 4U rack design is used to supply power to the digital power amplifier module
installed in the chassis.
(2) Provide 4 channels digital power amplifier module slot + 1 channel standby digital power
amplifier module slot.
(3) The operation and fault status of the digital power amplifier module can be displayed.
(4) It can show whether the standby power amplifier is in working state or not.
Support redundancy for power supply, usually from the power supply A, when the power supply A
fails, it can automatically switch to the power supply B; when the power supply A returns to normal,
it will automatically return to the power supply A.
Digital Power Amplifier Module:
(1) Class D digital power amplifier, high efficiency and energy saving.
(2) There are three power levels of 125W / 250W / 500W to choose from.
