Public Address System: Choosing The Best Solution Provider In Nigeria


A public address system is a set of electrical equipment consisting of loudspeakers, amplifiers, microphones and other interrelated equipments. This set of electrical equipments help increase the loudness of a musical instrument, human voice, or even recorded music. It allows music or someone’s voice to be heard over and throughout a large area like in a social gathering, conference, Party, auditorium etc. Public Address System can also be used in various places to increase the sound level of a speech such as in a theater where it can be used to pass across information as an announcement over a large audience. Public Address System is an electronic amplification system and can also be referred to as PA system. It is also mostly used by performers, announcers etc. Typical application includes sports stadiums, Airports, Transport Parks, public transportation vehicles, Schools, Churches, Marketplace, facilities, live or recorded music venues and events.

 

COMPONENTS OF A PUBLIC ADDRESS SYSTEM

Mixers

A mixer allows for multiple input of audio signals and equalizes them for broadcast at different levels. If a microphone or another acoustic source is used in a Public Address system, it is plugged into a mixer. A professional level mixer will have multiple inputs to accommodate lots of microphones while a simple mixer will only allow few inputs. There different types of mixers depending on what’s suitable for you; Digital mixers (They use digital signal processing technology), Analog mixers (for adjusting volume and tone of input audio signals) and Powered mixers (Powered mixers are analog mixers with built-in power amplifiers).

 

Microphones

Every Public Address System needs Microphones. There are basically two categories of microphones; The Condenser and Dynamic.

Condenser mics generally work on phantom power and would require mixers with sufficient built-in phantom-powered inputs. They are made to capture more intricacies and are used to handle high sound pressure levels. They are usually for live sound and recording. Condenser mics phantom power can also be delivered from other sources like mic cable, mic preamp, or from a standalone phantom power device.

 

Dynamic mics provide multi-pattern function by netting sounds from different directions. Dynamic mics are long-lasting, reliable, and are made for onstage use. While condenser mics are good for high frequencies also note that they are prone to breakage, which is a downside to their usage. Other kinds of microphones include the wired and wireless microphones.

 

Public Address Speakers

Speakers allow performers, announcers and musicians to hear themselves while performing to an audience. Speakers with higher wattage, size, sound quality, and weight are more effective compared to those with less features. The wattage determines how high and loud the volume would be without any breakage. The Size and weight of the speaker also help in expanding the sound output. Size and weight of a speaker is measured in inches and diameter. Sound quality on its own helps with clarity and as such provides the performer with a clear and loud sound output.

 

Speakers can also come in different forms like active or passive speakers. Active speakers are known also as powered speakers. They are loudspeakers with built-in amplifiers. They are ideal for reinforcement systems, professional public speakers, DJ(s), bands etc. Active speakers have several advantages, the most evident being their compactness and easiness. They are capable of being connected directly to an audio signal source without any external amplifier.

Passive speakers vary from active speakers in that they require external amplifiers or mixers to power them. Passive speakers are not an all-in-one system and therefore will require you check for compatibility between your speaker, amplifier and power ratings to avoid risking a blow-up of speakers.
