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 picture to your TV and speakers. Typically, an AV receiver includes multiple input and output ports, allowing you to connect several devices simultaneously. It often supports surround sound formats, enhancing your viewing experience by creating immersive audio. Many modern AV receivers also come with built-in Wi-Fi and Bluetooth for wireless streaming.
