The term 'Component Sound System' refers to a system of audio components that work together to produce sound. The three components of this system are the preamp (6 letters), EAR (3 letters) and STEREO (6 letters). The preamp is an electronic device that amplifies a signal before it is sent to other components. The EAR is a device that converts sound waves into electrical signals. Finally, the STEREO is a device that produces sound from two or more channels. Together, these components form a complete sound system.
