An Audio/Video Receiver (AV Receiver) is designed to handle both audio and video signals, primarily used in home theater systems. Its main function is to receive, decode, and process signals from various audio and video sources such as Blu-ray players, game consoles, and televisions, and then output the processed signals to appropriate audio and display devices. AV receivers typically feature multiple input and output interfaces to connect various devices.
AV receivers mainly involve signal decoding and amplification. It first receives audio and video signals from different source devices and converts these signals into digital format through internal decoders. Many great distributors like Heisener offer a wide range of components of AV Receiver to cater diverse application needs.
The AV receiver then processes and enhances the audio signals, applying effects such as virtual surround sound and sound adjustments, before outputting the amplified audio to speakers. For video signals, the receiver performs image processing and enhancement before transmitting the video to a display or projector.
AV Receiver Electronic Components
In an AV receiver, several key electronic components play distinct roles:
Decoder: Converts receive digital audio and video signals into a format that can be processed. Audio decoders handle formats like Dolby Digital and DTS, while video decoders process HDMI signals.
Power Amplifier: Amplifies processed audio signals to sufficient power levels. Typically, power amplifiers have multiple channels to support multi-channel audio systems.
Signal Processor: Handles further processing and enhancement of audio and video signals. Audio processors may include virtual surround sound and equalizers, while video processors handle image enhancement, scaling, and color correction.
I/O Interfaces: Include HDMI, optical, coaxial, and RCA connections for linking various audio and video source and output devices. They manage signal reception and transmission.
Power Supply Module: Provides stable power to the AV receiver, ensuring consistent performance.
Control Unit: Contains microcontrollers or digital signal processors (DSP) to coordinate the operation of components and manage user inputs and settings through a remote control or front panel.
