An AV receiver is a device that acts as the central hub for your home entertainment system. It receives audio and video signals from various sources, such as Blu-ray players, gaming consoles, and streaming devices, and then processes and amplifies these signals to deliver high-quality sound and video to your TV and speakers. AV receivers typically include multiple input options, allowing you to connect several devices at once. They often support surround sound formats, enhancing your viewing experience by creating immersive audio. Many modern AV receivers also come with built-in Wi-Fi and Bluetooth capabilities for streaming music and other content wirelessly.
