What Is a Home Theater Receiver?

A home theater receiver, also known as an AV receiver, is basically the heart of home theaters. It powers the entire system by receiving, interpreting, and processing the audio signals prior to sending and connecting them off to televisions and speakers.

A home theater receiver usually contains a minimum of five amplifiers to be able to drive five or even more speakers. Each of them contributes to making surround sound by using unique and separate signals from the receiver. Today, several home theater devices are made with more than five speakers, which can either be built-in or hidden on ceilings and walls of houses.

In general, a home theater receiver provides its users with a simple and cost-efficient way to centralize the entire home theater system. It combines several functions into three components:

  • AM/FM Tuner

This allows access to internet music streaming and radio services. Some even include an additional built-in feature for HD access.

  • Preamp Control

This selects the source of the audio or video. It processes and filters the incoming signals before distributing them to several channels and outputs.

  • Built-in Multi-Channel Amplifier

This involves the multiple channels that send out sound powers and signals to speakers.

How Does a Home Theater Receiver Work?

A home theater receiver is composed of the audio or video inputs, pre-amplifier, surround sound decoder, power amplifiers, and outputs.

Basically, a home theater receiver works in a straightforward way. The source inputs, including DVD or DVR players, will feed the signals to the receiver. After which, the desired input component will be chosen and fed to the output unit. The pre-amplifier will select the signal and further amplifies it to another level.

The receiver will send images and videos to the television. Audios will also be sent to the decoder for sorting prior to sending to the amplifier. These amplifiers will then connect the sound outputs to their appropriate speakers.
