The receiver acts the central point of the entire system. It performs a variety of functions like switching on all your audio and video components, decoding the surround sound system, bass management, and signal processing for simulated sound fields. It also drives the loudspeakers by amplifying the audio signals. Additionally, it also serves as an AM/FM radio tuner. With all these functionality, the receiver is one of the most complex and expensive component of the home theater audio receiver system.
We can do with a few more details on the surround sound decoding process. The source material contains surround sound in coded format, and one needs to decode them into separate channels to power separate loudspeakers. As we have seen earlier, the current de facto standard is 5.1 channels. Of course, 6.1 channels are also widely available. But very few movies and channels are encoded at this level or have extended surround sound formats.
A home theater audio receiver is the heart of the home theater system. It provides almost all the inputs and outputs that one can connect into, including your television. It provides an effective and professional way of centralizing the home theater system. However, you must base your choice on specific needs and area. It would be better if one actually tries out the system and check out its sound quality and additional facilities before going for an installation.
