Technology can seem like it is impossible to figure out, but the truth is that almost anyone can set up a home theater system in their house if they know the components that need to be included. One of the most confusing things is how each sound knows what speaker to go to. That is the job of the receiver. This device decodes signals from the inputs, whether they are DVD player, satellite dish, or cable television, and routes them to the television or the speakers. There are subtle differences between the different models out there, but there are some important things you will want to consider.
First, you want to make sure you are selecting a device that is Dolby Digital 5.1 compatible. That is the current standard for most DVDs. If you are thinking about investing in something that will last for the long term, think about going with Dolby Digital Surround EX or Digital Theater System ES. Rather than having six channels of audio, these formats divide the signal into seven or eight channels. This promises to be an even more realistic listening experience, but of course you will need more speakers for this. You can choose a receiver that processes both options so you are still prepared if you choose to upgrade in the future.
Most receivers come bundled with a pre-amplifier in order to equalize the audio signal, as well as a power amplifier to boost it. These components can also be purchased separately if needed. Having stand along pre- and power amps gives you the ability to fine-tune and upgrade individual speakers more easily. It also allows you to generate superior sound at high volumes. Unfortunately the cost of doing this can add up quickly. Regardless of if you have amps that are integrated or not, you want to be sure that you have a receiver that supplies at least 100 continuous watts per channel rather than peak. The letter RMS should spear next to the wattage rating. You will also want to make sure it has enough outputs to connect all of your speakers.
Having the right speakers for your space and enough outputs for everything to work properly can give you the awesome, theater-worthy surround sound you have been dreaming of. You can work with a professional to find the best speaker system for your room, or do the research yourself. Check out http://londonavsolutions.co.uk/audio/home-cinema.php to find out more.
