                  Public broadcasting | public broadcasting system knowledge popularization

                  2016-11-24 15:36:12

                  The administration of public broadcasting is by using the units themselves within the scope of this unit for the voice of the public service broadcasting,

                  including business background radio broadcast, and emergency broadcast, etc.


                  Background radio: public broadcasting system sends the rendering environment atmosphere of broadcast its service area. Including the background

                  of the background music and various occasions sound (including environmental simulation), etc.


                  Business radio: public broadcasting system, needs to be transmitted to the service area of all or part of the audience to listen to broadcast daily.

                  Including notice, news, information, voice files, paging, time, etc.


                  Emergency broadcast: public broadcasting system to cope with the sudden public events and broadcast to the its service area. Including alarm signal,

                  guiding the evacuation of the public information and the relevant departments for on-site command command, etc.


                  The public broadcasting system equipment is what?

                  Including broadcasting speakers, power amplifiers, transmission lines and transmission equipment, management/control equipment, paging, microphone

                  and other signal devices. Radio transmission lines are usually quite long, dozens of meters and even thousands of meters, to reduce the transmission loss,

                  in principle is to use radio signal transmission high voltage/current. Radio amplifier is constant voltage output mode, the output terminal marked 70 v / 100 v

                  (CTRLPA customizable output 200 v / 240 v) and other specifications; Radio speaker should be a high resistance, its input terminals are marked 70 v / 100 v

                  voltage applied specifications as shown in the figure below:


                  Below is from the beginning of the simple and easy to functional complex public broadcasting system is introduced in this paper, the simple type radio

                  system as shown in the figure below:

                  This simple system can only be released voice broadcast, if you want to play background music, radio news, recording, can buy CDS, tuner (radio),

                  MP3 players and other devices. Radio and power amplifier are usually equipped with multiple input interface circuit, can be easily connected with

                  these equipment, as shown in the figure below:

                  Some of the equipment. Such as CTRLPA brand CT938U CT928U/CT1060UII/CT9350U combined power amplifier with U disk/SD card play, tuner,

                  bluetooth push, call it with audio "all-in-one", as shown in the figure below:


                  This simple system can only be released voice broadcast, if you want to play background music, radio news, recording, can buy CDS, tuner (radio), MP3

                  players and other devices. Radio and power amplifier are usually equipped with multiple input interface circuit, can be easily connected with these

                  equipment, as shown in the figure below:


                  Configure the audio source, partition management, programming of the system such as timing, as shown in the figure below:


                  Configure the audio source, partition management, monitoring, programming, timing, partitioning paging, fire linkage and adjacent zone alarm system,

                  as shown in the figure below:


                  Of course, if you want to realize more complex functions, can be configured using powerful intelligent to solve matrix system, as shown in the figure below:


                  Or configuration is the most advanced digital broadcasting system is used to solve, in addition to the conventional systems and intelligent matrix system

                  outside of all functions, can also realize the nets, interface image intuitive touch-screen control, join an infinite number of broadcasting partition, all partitions

                  in any combination, the share of interaction, all kinds of input multipriority, set the permissions on the intercom function, audio collection, management, operation

                  log for future reference, and other functions, as shown in the figure below:
