What is the difference between a stereo receiver and an AV receiver?

The primary difference between a stereo receiver and an AV receiver lies in their intended functionality and the audio capabilities they offer. A stereo receiver is designed specifically for two-channel audio systems. It amplifies sound from two separate channels, making it ideal for music listening in a more traditional format. These receivers typically include a built-in AM/FM tuner and may incorporate features such as Bluetooth connectivity or Internet radio, but they focus primarily on producing high-quality audio from music sources. On the other hand, an AV receiver, or audio-video receiver, is a more versatile device that handles both audio and video signals. It is designed for home theater systems and can decode various surround sound formats, such as Dolby Atmos or DTS. An AV receiver supports multiple channels and can drive multiple speakers, typically providing five or more channels for a comprehensive surround sound experience. Additionally, AV receivers often include numerous input options, including HDMI ports for video connectivity, making them suitable for high-definition video sources like Blu-ray players and streaming devices. In summary, if a user is looking for an immersive home theater experience, an AV receiver would be the right choice, while those who prioritize music playback may find a stereo receiver more suitable.
