A public address system (PA system) is an electronic system comprising microphones, amplifiers, mixer, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. A PA system may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution.
Our public address and voice-alarm systems range from the most advanced systems in IP technology and digital public address equipment, for large and complex facilities with certified equipment, to more basic small and medium analog solutions for playing ambient music, always trying to achieve suitability, reliability and ease of use by the end user.
Small PA System
The simplest, smallest PA systems consist of a microphone, an amplifier, and one or more loudspeakers. PA systems of this type, often providing 50 to 200 watts of power, are often used in small venues such as school auditoriums, churches, and coffeehouse stages. Small PA systems may extend to an entire building, such as a restaurant, store, elementary school or office building.
Large PA System
We conduct studies and propose solutions based on IP networks, through FO or hybrids, for decentralized or centralized systems, both with DSP equipment.

Ceiling - Wallmount - Column/Pillar PA Speakers
Whether you are a teacher speaking to a noisy assembly of grammar school students or you are a tour guide in the middle of a major city, you are going to need some help overcoming ambient noise to get your message heard. That's where a PA (Public Address) system comes in handy. It allows presenters to communicate effectively, and is available in a variety of sizes and configurations.
Simple PA systems are often used in small venues such as school auditoriums, Masjid, and small halls. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings and locations, such as schools, stadiums and large passenger vessels and aircraft. Intercom systems, installed in many buildings, have both speakers throughout a building, and microphones in many rooms allowing the occupants to respond to announcements.
Types of Microphone Are Used with PA systems
Construction is simple and comparatively sturdy. No power supply is required. Relatively inexpensive.
Good sensitivity at all frequencies. Power supply is required. Vulnerable to structural vibration and humidity.
This type of microphone features directionality to the front only and is also known as "cardioid" (because of its heart shaped directional pattern). Cardioid mics are most often used with PA systems for vocals, instruments, etc.
This type of microphone features directionality to the front and rear. Because bidirectional microphones will also pick up audio to the rear, they are rarely used with PA systems. They are often used to record audio between two people who are face to face, such as during radio interviews.
As mentioned above, this microphone type has no directionality. "Omni" mics are used to pick up all or wide range audio. For example, they are used for choirs, when many instruments are played at once, or to pick up all audio on the stage.
1- Wireless microphones:
Wireless microphones can be moved around freely, without the cables getting in the way. These microphones require a transmitter and a receiver in order to broadcast sound. In general, handheld wireless microphones contain a built-in transmitter, whereas headset and clip-on microphones include a cable that attaches to the belt-pack transmitter.
The transmitters for both types are powered by batteries (either dry-cell or rechargeable), so always make sure that ample battery power is available. It's also necessary to set the transmitter of the broadcasting microphone and the receiver to the same channel. Make sure that when you are using more than one wireless microphone, the transmitting and receiving channels are set differently for each microphone.
2- Headsets and lapel microphones:
Microphones worn on one's head are called headsets, while microphones worn on clothing not far from one's mouth are called lapel (or lavalier) microphones. Either can be used so that both hands are free. Headsets are often used while singing or dancing, while lapel microphones are often used by presenters on television. These headsets and lapel microphones are often used wirelessly.
