A "Sound System" refers to a collection of audio equipment designed to amplify and reproduce sound. This setup typically includes components such as speakers, amplifiers, and mixers, which work together to deliver high-quality audio for various settings, including concerts, parties, and home entertainment. Sound systems can vary in size and complexity, from small portable units to large, professional-grade installations. They are commonly used in venues like clubs, theaters, and outdoor events to ensure that music and announcements are heard clearly by the audience. Popular brands in the industry include Bose, JBL, and Sony.
