Best Budget Pa System For Band - Top 14 Review

Balanced signals are transmitted with both a positive and a negative phase and use three transmission wires: hot, cold, and ground. In this case, a dual (hot and cold) shielded ground cable is used.

A public address system (or PA 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. 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. Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings and locations—such as schools, stadiums, and passenger vessels and aircraft. Intercom systems, installed in many buildings, have both speakers throughout a building, and microphones in many rooms so occupants can respond to announcements. PA and Intercom systems are commonly used as part of an emergency communication system. The term sound reinforcement system generally means a PA system used specifically for live music or other performances. In Britain any PA system is sometimes colloquially referred to as a Tannoy, after the company of that name, now owned by TC Electronic Group, which supplied many of the PA systems used previously in Britain.

There are three main types of PA speakers: mains sometimes referred to as “tops,” subwoofers, sometimes referred to as “bottoms,” and stage monitors.

There are three components to every PA system: An input transducer (microphones or line-level output from an instrument) Amplifiers (both preamps in the console and power amps in the speakers) An output transducer (speakers or headphones)
