What is the purpose of an AV receiver?

The purpose of an AV receiver centers on decoding audio signals and managing sound distribution to various speakers within a home theater setup. It serves as the central hub in an audio-visual system, allowing users to control audio output from various sources, such as streaming devices, Blu-ray players, and gaming consoles. By decoding audio, the receiver translates the incoming digital audio signals into formats that can be played back through the connected speaker system.

In addition to decoding audio, an AV receiver typically includes features for optimizing sound distribution, which means it can take cues from microphone setups to balance sound levels and ensure a uniform listening experience in the room. It can manage how sound is routed to different channels (e.g., front, rear, subwoofer) for an immersive surround sound experience.
