the mute adjustment potentiometer to adjust the volume of the mute level.
Outside the machine, there are the two kinds of powerful broadcasting output interfaces including EMC
24V and short-circuit dry contact, which are used to connect the audio controller of the loudspeaker, or
to connect the intelligent power supply.
It is equipped with the peripheral equipment expansion interface, which is used to connect 86-box
on-demand playing color screen, connect the double 86-box help intercom panel and dual-purpose
intercom panel, or connect the bluetooth audio receiver.
Function of playing on demand
:
After connecting the 86-box on-demand playing color screen, it is
possible to achieve the local on-demand playing of the mass program library of the host.
Function of paging
:
After connecting the 86-box on-demand playing color screen, it is possible to
implement the real-time paging for the selected zone.
Function of intercom: After connecting the help intercom panel, it is possible to achieve the function of
help intercom.
Function of bluetooth audio receiving: After connecting the bluetooth expander, it is possible to receive
the blue-tooth audio, so as to enable the school and marketplace to achieve the local wireless
loudspeaker sound amplification 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 power 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 firefighting address system.
It has the networking playing function, so that it is possible to play the program source distributed by
the networked host or audio stream of the networked 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 broadcasting, business broadcasting, and emergency broadcasting.
The decoding chip with high-definition 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 definition, and high audio
transmission indicator.
There is the built-in watchdog function to guarantee the normal operation of the equipment effectively.
Due to wide range of the working ambient temperature, the industrial-level chip design is adopted to
adapt to the 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 applicable to compensation in different environments so as to further improve the
broadcasting indicator.
The high-performance network processing chip and independently developed real-time processing
system are used, so that the startup time is less than 0.1S, and the time for connection with networked
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 independently developed real-time operation system has the strong real-time capacity, so it is
possible to achieve the real-time synchronization of the sounds of the programs broadcasted by several
network players without any difference in the time basically.
The independently developed network data stream decoding algorithm, microphone paging, and
