System Console PA System is often used in parks, factories, campuses, supermarkets, shopping malls, hotels, and stations. The name of System Console PA System products is different according to different places. We call them background music systems installed in supermarkets, shopping malls, hotels, and stations. We call it a campus broadcasting system when installed on campus, and we call it a rural broadcasting system or rural loudspeaker when installed in rural areas.
What should I do if System Console PA System products break down during use? Here are the following common faults and troubleshooting methods.
The basic composition of System Console PA System products
We need to overhaul the broadcasting system by ourselves, and we need to have a full understanding of the composition of System Console PA System products in order to find the fault point of the broadcasting system and then eliminate it.
System Console PA System products consist of: program source equipment, signal amplification and processing equipment, transmission lines, speaker systems and auxiliary equipment, etc.
System Console PA System products equipment: Program sources include CD/MP3 players, digital tuners, recording dual decks, smart broadcast controllers and other equipment.
Signal amplification and processing equipment: including various controllers and audio processing equipment such as mixers, preamplifiers, power amplifiers, power sequencers, monitors, frequency dividers, etc. The first task of this part of the equipment is signal amplification, followed by signal selection. The functions and status of the mixer and preamplifier are similar (of course, the function and performance of the mixer are higher). Their basic function is to complete the signal selection and preamplification. In addition, they also have the ability to adjust the volume and sound effects. Kind of adjustment and control functions. Sometimes in order to better perform frequency equalization and tone beautification, a separate frequency equalizer is also added. This part is the "control center" of the entire public broadcasting sound system. The power amplifier amplifies the power of the signal sent by the pre-amplifier or the mixer, and then drives the speaker to reproduce the sound through the transmission line.
Public broadcasting transmission line:
Although the transmission line is simple, it has different requirements depending on the system and transmission method. For auditoriums, theaters, etc., due to the short distance between the power amplifier and the speakers, 4~16Ω output ports can be used for output, and the transmission line requires a dedicated speaker cable; for the public address system, due to the wide service area and long distance, in order to reduce the transmission line For the loss caused by high-voltage transmission, a multi-strand sheathed wire with better insulation strength should be used.
Public address speaker system:
The loudspeaker system needs to match the entire broadcasting system, and the choice of its location should be realistic. Auditoriums, theaters, and dance halls have high requirements for timbre and sound quality, and speakers generally use high-power speakers; while public address systems, which require less timbre, can choose ceiling speakers, wall-mounted speakers, outdoor sound columns, etc. Lawn speakers, garden speakers, outdoor horns, etc.
Public broadcasting auxiliary equipment:
In order to meet the needs of different customers, it is usually necessary to equip the corresponding auxiliary equipment in the System Console PA System products project. Such as power sequencer, smart broadcast monitor, main/standby power amplifier switcher, smart broadcast partitioner, etc.
