subject: Yamaha Rx V 1800bl 7.1 Receiver [print this page] If you buy almost any receiver today it must have DTS (Digital true Surround) and it should be able to handle surround sound systems, what that means is that the sound coming out of your surround sound system will sound more practical to you than the monophonic option.
By making your receiver that you bought the main brain of your surround sound system you will be able to manage between all the different audio/video components that you have by only using only one remote for all the components and you only have to press one button to select them.
The most common type of receiver -5.1-channel models- decode the audio information contained in Dolby Digital and DTS soundtracks and route them to front left and right, center, and surround speakers in your system via their five built-in amplifier channels.
With a home theater audio receiver you will get digital processing as well as digital outputs and inputs. Additionally, you will get speaker calibration automatically. This means that your system will analyze the sound coming out of your speakers and adjust it automatically.
7.1-channel receivers are basically the same as 6.1-channel models, but they include yet another amp channel to drive a second back surround speaker. In this case, the audio information going to both back speakers is identical; it's just distributed between the two back speakers to create an even more expansive rear sound field.
The surround aspect of your home theater system will have you enveloped in sound so that you will feel like you are in a commercial theater right in your house. Check product reviews and make sure that you're getting the best your money can buy. Make sure you take the time to check out how the receiver handles before you buy.
