What is a radio AV receiver used for?

A radio AV receiver is an audio-visual device that combines the functions of a traditional radio with those of an AV receiver. It allows users to listen to AM/FM radio stations as well as connect external devices such as DVD players, Blu-ray players, and game consoles. The receiver then processes and amplifies the audio and video signals from these devices and sends them to the appropriate output devices, such as speakers and a television. Some AV receivers also include features such as built-in streaming capabilities, multi-zone audio, and room correction technology.
