Sound equipment is a broad term that encompasses a variety of items used to produce, record, and amplify sound. Amplifiers (AMPS) are devices used to increase the volume of an audio signal. Microphones (MIKES) are used to capture sound waves and convert them into electrical signals. Stereos (STEREO) are systems that use two or more speakers to create a surround sound experience. All of these pieces of sound equipment are essential for creating and enjoying music.
