A Hi-Fi Sound System is a type of audio system that produces high-fidelity sound. It typically consists of two or more speakers, an amplifier, and a source such as a CD player, turntable, or radio. The term 'Hi-Fi' is derived from the phrase 'high fidelity, ' which refers to the ability of the system to accurately reproduce sound. The STEREO component of a Hi-Fi Sound System is the two-channel audio system that produces left and right channels of sound.
