of the machine and the clock of the network host.
The built-in infrared receiving module is under the control of the infrared remote controller, easy to use.
The panel integrates 5 status indicators to show the working conditions clearly.
On the panel, there are 8 shortcut buttons, facilitating the daily use of the local user.
It has the built-in offline local timing-point playing function, so as to back up and store the timing
programs into the SD card, and back up the timing-point programs automatically.
Outside the machine, there are a channel of AUX line input, a channel of microphone input, and a
channel of AUX line output, in order to facilitate the expansion of the other local sound source
broadcasting and expansion of local power.
Outside the machine, there are the two override output interfaces including EMC 24V and short-circuit
dry contact to connect the audio controller of the loudspeaker, or the intelligent power supply.
It is equipped with the peripheral equipment expansion interface, which is used to connect 86-box
on-demand color screen, double 86-box help intercom panel, dual-purpose intercom panel, and the
Bluetooth audio receiver.
On demand: After connecting the 86-box on-demand color screen, it is possible to achieve the local
on-demand of the mass program library of the host.
Paging: After connecting the 86-box on-demand color screen, it is possible to implement the real-time
paging for the selected zone.
Intercom: After connecting the help intercom panel, it is possible to achieve help intercom.
Bluetooth audio receiving: After connecting the Bluetooth extender, it is possible to receive the
Bluetooth audios, so as to enable the school and marketplace to achieve the sound amplification of the
local wireless microphone with the Bluetooth wireless microphone.
There is a mixed relation between the external line input and the program source for network playing.
The local microphone and AUX input will turn on the amplifier by detecting the size of the input signal.
It is allowed to tailor the linkage trigger function and 100V local emergency line input, in order to
facilitate the access to the local public address system for firefighting.
It has the network playing function, so that it is possible to play the program sources distributed by the
network host or audio streams of the network audio collector.
It is possible to play the background music, emergency paging, and alarm signal from the system host.
The network program source has the priority management function at the level 7 or above, and it is
classified into the background broadcast, business broadcast, and emergency broadcast.
The decoding chip with high-fidelity CD tone is used to support 16-bit MP3/WMA/WAV/PCM audio
stream data decoding with sampling rate at 48KHZ to the maximum extent.
Fully digital design with advantages such as high performance, high fidelity, and high audio transmission
indicator.
There is built-in watchdog function to guarantee the normal operation of the equipment effectively.
With the industrial-level chip design, it has wide range of working temperature for outdoor installation
and use.
There is the built-in DSP sound effect processing chip to achieve the function of high and low pitch
adjustment, so it is suitable for compensation in different environments so as to further improve the
broadcasting indicator.
It adopts the high-performance network processing chip and independently developed real-time
processing system, so that the Boot time is less than 0.1S, and the time for connection to the network
host is less than 2S, resulting in the high real-time capacity; the time delay for broadcasting of real-time
program is less than 0.2S.
The self-developed real-time operating system has strong real-time performance, and the broadcast
program sounds of multiple network players are synchronized in real time, and there is basically no time
difference between them.
The independently developed network data stream decoding algorithm, microphone paging, and
