There Are All Types Of Audio Receivers
What is an "Audio receiver"? The answer is quite simple, a device that receives signals from various input devices and it interprets and amplifies those signals and then sends them to output devices. The term "Audio receivers" originally referred to a component which included a tuner, a pre-amplifier and a power amplifier. The modern receiver so called AV receivers have networking capabilities and can play music from the internet, or music stored on a computer or media server.
Now, you are in the market to buy a home theater system that brings a vast body of entertainment to life. The A/V "receiver" and amplifier assembly in a home theater does the same job as the receiver and amplifier assembly in any stereo system. The "receivers" send the video on to your television and send the audio to the decoder. The decoder sorts out the different sound channels from the video signal, and then sends the information to the amplifiers which are connected to the suitable speakers. A home theater actually combines several different components and even has a DVD or other media player built in. You can assemble a good quality home theater, but it's better to buy one unit that does all these jobs.

5.1 channels surround sound: This means 5 channels of full frequency, plus a single low frequency effects channel for an optional subwoofer. The new and emerging surround sound formats are the 6.1 and 7.1 channel with the extra addition of a full-frequency back surround channel. So if you are considering the 6.1 format, many mid priced "receivers" are available in market. Also the more expensive receivers will have 7.1 channel formats, though in any case the subwoofer output is not amplified.
Decoders: A/V "receivers" usually provide one or more decoders for sources with more than two channels of audio information. As you know movie sound tracks have been provided via a number of encoded formats which include a center channel and a surround channel. With the introduction of DVD, the Dolby digital format became a standard format and most current A/V "receivers" are provided with Dolby digital decoder which provides a Dolby digital output.
Digital signal processors (DSP) effects: Most "receivers" offer DSP made for handling various audio effects. Some may offer simple equalizers and balance adjustments to complex DSP audio field that stimulate the audio being played in the places through use of surround sound and echo effects.
