Today’s home audio systems can range from a simple unit with several different functions or several different components that make up a larger stereo system. These components can include receivers, CD players, cassette decks, equalizers, speakers, amplifiers, clock radios, MP3 players and more.

CD Players are available in single or multidisc formats. Multidisc players can come in 3, 5 and even up to 100-disc models, holding your entire library. They can also play CD-R, CD-RW and in some cases, MP3 formats. DVD players double as a CD player.

Receivers come in a number of shapes and sizes as well. Generally speaking, receivers include an AM/FM tuner and connections for attaching other audio components. Typical inputs include an antenna/cable for use with most any video source; composite-video for use with DVD, digital-cable boxes, satellite receivers and camcorders; S-video for improved video quality over composite video; and component-video providing the best connection for use with high-definition or DVD products.

Perhaps the widest variety in home audio is the speakers. They can come in a variety of shapes and sizes, not to mention power outputs. And they can serve a variety of different functions.

Bookshelf speakers can reproduce a wide range of frequencies, meaning they are ideal for multiple purposes. They can be used as the only speaker for a conventional stereo system or stereo television, as well as for the front or rear speakers of a surround sound system.

Front speakers are for use with a home theatre equipped with surround sound and can produce a variety of frequencies for both on and off-screen sounds.

Center-channel speakers reproduce onscreen sound and dialogue. They are usually located just above or below the screen and are shielded should the magnet will not interfere with the television picture.

Rear speakers complete the surround sound experience by providing background sound, adding an element of realism.

Subwoofers are usually placed on the floor and have a built-in amplifier to maximize bass output.

Many of today’s high-tech devices tend to “leak energy,” even when powered off. Lights, clocks and other digital displays all consume power when turned off. Audio equipment accounts for 25% of standby loss. A more shocking statistic is that the average stereo is used for approximately 1 hour a day. This means that 93% of a stereo’s energy use is consumed when the stereo is in the off position.

To see how you can reduce your home audio system’s energy leakage, see the tips located below.
