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 send them to your speakers and TV. AV receivers often come with multiple input options, allowing you to connect several devices at once. They also support various audio formats, including surround sound, enhancing your viewing and listening experience. Many modern AV receivers include features like Bluetooth and Wi-Fi connectivity for streaming music and video directly from the internet.
