PAS (public address system) is an electronic system comprising microphones, amplifiers, 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.
The small PA systems are usually battery-powered portable systems. The systems are optimized for speech as well as background sound. The system’s components are so simple: a microphone (or an equivalent recorded sound playback device), one or more loudspeakers, and an amplifier. The systems are suitable for small venues and meeting rooms. They also could be extended to cover the entire building or restaurant or hotel, but that required more loudspeakers and amps.
Large distributed PA systems are very similar to the smaller ones. But it typically has more amplifiers designed to output high power at high voltage. The high voltage is transmitted through hundreds or thousands of small loudspeakers distributed in various locations. This is suitable for the hospitality industry, for example. Hoteliers could distribute small speakers throughout the hotel rooms, lounges, halls, and more.
IP Based Network Public Address system is a new IT solution offered by BITS Arabia. Public Address over Internet Protocol refers to the system installed by the PA system through the existent IP networking in the building. The PA over IP system replaces the central amplifiers with the IP networking devices. Network-attached amplifiers and intercoms are used to distribute the audio signals to locations across the building\s.The IP public address system does not require new IP networks. It rather exploits the existing type of IP system.
Wireless Mobile Telephony (WMT) Public Address Systems is a new IT solution BITS Arabia presents. It refers to the paging system that uses the existing wireless mobile telephony systems instead of a centralized amplifier.The system distributes the audio signals to the GSM transceivers. It then reproduces the analog audio signals through a power amplifier and loudspeakers. Other wireless mobile communication devices are used, such as the existent sound system and back-end systems.
