Speakers
For a PA system, speakers are one of the most important components.
PA speakers come in many shapes and sizes, depending on the needs of different events.
There are three main types of Public Address Speaker speakers: main speakers, monitor speakers (monitor speakers) and subwoofer speakers.
Some event occasions may only require a main speaker, such as a small meeting or lecture.
Music performances require comprehensive musical effects, which require more speakers.
Main speaker is the main sound source and will use large-size speakers: 8"-15".
The main speaker is usually placed on a stand or above the subwoofer.
For example, the AS-PA01 is a 15" main speaker.
For monitor speakers and subwoofers, we will introduce the chapter "PA Speaker Types."
Amplifiers
The function of the amplifier is to amplify and process the weak current signal of the audio source device (player, smart product, computer, etc.), and transmit the signal to the speaker to produce sound.
Only passive public address speakers need amplifiers, active PA speakers do not need amplifiers.
The amplifier is one of the three core components of the audio system (speakers, amplifiers, and sound sources), especially in large PA systems.
Mixing Consoles(PA System Mixer)
It is also a PA Speaker System, especially for large-scale performance sound systems.
The mixer can combine different sounds or change the volume and timbre of different audio signals during playback to make the sound more in line with the scene atmosphere.
The mixer can output multiple channels, including left and right main channel outputs and individual channel outputs.
Sound Source Equipments
The sound source equipment in a public address (PA) system is a device that converts sound into electrical signals.
Its working principle is opposite to that of a power amplifier.
Common ones include microphones (vocal collection), instrument pickups, line level equipment, etc.
Audio Cable
Different scenarios, including scale, current environment, and equipment, require different wiring methods to make the public address system speaker work.
Commonly used cables include XLR, Speakon, and TRS.
Cabling is crucial to the PA speaker system, which determines whether the system can work properly.
Professional or performance PA systems need to be completed by professionals.
