How to choose stage speakers? In addition to looking at the price of the audio equipment, you also need to pay attention to these two key points
What is a PA speaker?
PA, short for Public Address, utilizes professional, comprehensive audio equipment to amplify sound throughout a space, ensuring the smooth progress of meetings or events. PA systems have a wide range of applications. Besides amplifying vocals at events, they can also be used to plan and design sound reinforcement systems in settings requiring public announcements, such as campuses and factories.
Introduction to PA audio equipment, let you know what you need to know to get started with PA audio
After the sound is picked up by the microphone, it generates a sound signal, which is transmitted to the mixer through wires or signal cables. The mixer adjusts and mixes the signal and transmits it to the amplifier, which amplifies the signal and outputs the sound through the speaker.
Therefore, the PA system is mainly composed of an amplifier, speakers, and microphones. Sometimes, in response to multi-track audio sources, a mixer is used to make the sound presentation more complete. The following introduces each PA device separately.
1. Amplifier: In the entire audio project, the amplifier is responsible for amplifying the sound signal and supplementing it with the sound output of the speaker so that the sound can be fully heard anywhere in the space.
2. Speakers: In a sound system, speakers are responsible for converting signals into audible sound. They are categorized by purpose as main speakers, subwoofers, and monitor speakers. Main speakers primarily amplify sound to the audience. Subwoofers are used alongside the main speakers and are designed to produce low-frequency sounds. Monitor speakers are specifically designed for on-stage listening by musicians and performers. Their sound dispersion principle differs significantly from that of the main speakers and should not be used interchangeably with them.
3. Microphone: Different types of microphones have different sensitivity ranges for receiving sound. Here we use common omnidirectional and unidirectional microphones to illustrate.
(a) An omnidirectional microphone, as the name suggests, is equally sensitive in all directions, picking up sounds regardless of where they come from. A typical microphone worn by a speaker is of this type.
(b) A unidirectional microphone is sensitive only to sounds in front of the microphone and has poor sound pickup in other directions. Common handheld microphones are of this type.
4. Mixer: Choosing a mixer first depends on the number of audio inputs, the number of amplifiers and speakers, the number of output channels, and finally, the mixer's functionality, such as whether it requires built-in effects. Common types include analog, digital, and power mixers.
How to choose a PA audio company?
When choosing a PA audio company to rent, in addition to considering the price of the audio equipment, you need to pay attention to the following two points:
1. PA audio equipment quality
Usually, the websites of audio rental companies will list the equipment available for rent. You can first check the product introduction of the equipment on the website to understand the quality of the equipment. JBL EON 612 Active Speaker, which is a high-powered portable PA sound system. This device combines 70 years of professional speaker manufacturing technology with the latest technology to present complete and high-quality sound.
2. The company's professionalism and experience in co-organizing events
When renting sound equipment, you'll typically submit your requirements to a sound company, who will then provide a quote to confirm the lease and discuss adding or reducing equipment. When negotiating with sound equipment, consider whether the company has a clear process and their experience in event planning.
