Definition: A/V receiver


(Audio/Video receiver) A combination audio amplifier and audio/video switching device for a home theater. An A/V receiver contains inputs for audio and video sources such as a turntable, FM tuner, cable TV box, Blu-ray player and Apple TV or Roku hub (see digital media hub).

The receiver's video output goes to the TV via HDMI, and audio outputs connect to speakers and subwoofer using stranded speaker wires. See HDMI and speaker wires.

Surround Sound Processors
A/V receivers support several movie soundtrack formats such as Dolby Digital, Atmos and DTS. They also have built-in audio effects to enhance music and movies. See surround sound.

Receivers Have Amplifiers
Although an A/V receiver has its own amplifiers to power the speakers, it generally provides outputs to external audio amplifiers if more speaker power is required. In such a case, the receiver functions as a preamplifier (see preamp). See home theater, stereo receiver, digital media hub and digital media server.
