The audio of a good home theatre system is very important. Though a lot of HDTVs may deliver good quality audio, not all built-in speaker systems will be satisfactory. If you have invested a great deal of money in getting a system that gives you top quality images then you may not want to compromise with the audio. You will require high-end audio to enjoy your home theater system. For this you will require a good set of speakers and a receiver.
Home theater and the standard stereo receivers are alike – the home theater receivers will support more channels. While the stereo receivers have only about two channels the home theater receivers support up to either five to seven channels.
Receivers must have enough output power. They must have the power to drive a large number of speakers. High power is required to get ample volume and noise-free sound. The HDTVs can not deliver 10 watts on each speaker. In home theater systems it can be between 30-50 watts or maybe even more on each channel. High power will help you enjoy your home theater system better, but remember, high power is expensive.
Receivers must have lots of ports and different variety of ports as this will help connect other devices you might want to use through them. You will need two HDMI that is High Definition Multimedia Interface ports and you will have to attach other components like video and speaker connectors. You could also have an FM-tuner and satellite radio receiver fixed to it.
A speaker system consists of three speaker sets. If you can not get extra speakers then you could use the stereo system already available at home. If you have extra speakers and your receiver has seven channels then you can have multiple speakers and connect each speaker to each channel.
To make your system one of the best and the most powerful ones you could use five speakers. You could use front-channel and surround system speakers on both the sides and one speaker at the center called the center-channel speaker. A special sixth one, an extra speaker that is called a sub-woofer may be added.
The speaker at the center, called the center-channel plays the conversation and the left and right units produce background and other sound effects. There may be a certain amount of overlapping between sources in any system otherwise it could sound unnatural.
The sub-woofer carries very low frequency sounds like the special effects in movies, gunshots, crashing buildings, jets etc.
The surround speakers are placed behind or onto the sides of the system and they produce the three hundred and sixty degree effect that all of us are used to from multiplexes and theaters. In addition to this, 3-D audio may also be added.
You must get a video-shielded system as the modern day HDTV sets do not have an electron gun and are not sensitive to magnets that are in the speaker systems.
Any set you buy has to be synchronized. Most manufacturers make sure that the speakers they offer for sale have seamless integration. Before buying a system you must ensure that it is able to produce a realistic, high-end audio experience.
