Details Regarding Stereo Receivers

By James Cherry


A receiver is the fact that large, heavy factor that you simply plug your loudspeakers along with other components into (just like a DVD player, TV, Compact disc player, Xbox 360, Ps, ipod device, and etc.). It is the "brain" from the show, really. The thought of hooking up all of your components to home stereo receivers is the idea of audio/video switching, permitting you to definitely change to different video sources (like TV, DVD, video camera) in your TV and therefore altering the audio source accordingly - all without touching not the receiver.

Obviously, the primary purpose behind audio/video switching having a receiver would be to drive audio to exterior loudspeakers, like multichannel audio or stereo system loudspeakers.

Most devices have an array of inputs as much as 8 loudspeakers along with a subwoofer (more generally, 5.1, or five loudspeakers along with a subwoofer), several video inputs, as well as High-definition multimedia interface inputs. You can plug your Xbox 360, Plasma, and DVD player in to the receiver and employ one remote to change between all of the different video sources (games, TV, DVD video) and also have your loudspeakers generate surround-seem.

Let's start with inputs and results. If you don't understand something, read vehicle How-To since most of it'll be referred to in more detail.

Keep in mind the receiver might be the hub from the entire home theatre, and this How-To will truly demonstrate using the basic principles of connecting your complete home theatre.

So what the heck is all this 'stuff' on the back of your receiver?

I'm going to go over just about anything that you would find on the back of your receiver. The one I'm basing this guide off of is a Harman Kardon AVR-247 I'm going to start from the top left of the unit and work my way to the right, then I'll start at the left of the next row and so on.

The very first three inputs are for antennas. An FM antenna cable would slide onto the very first jack while two speaker wires would plug in to the remaining slots for AM. Obviously, it's not necessary to plug your antennas in, but when you would like AM/FM reception using your loudspeakers, you will want to proceed and do this. They are standard connections, if you lose your antennas, go buy another for any couple of dollars.

You've most likely heard about composite video. Its a really fundamental video connection utilized by nearly all component (TV, DVD, VCR especially). Its common and it is cheap. As a result, its really low quality.

Composite uses an RCA cable for video (yellow) and a pair of more RCA cables for audio (red-colored-colored and white-colored, stereo system system). The problem would be that the composite video cable combines luminance and chrominance inside the same cable, lowering the standard in the picture. You lose plenty of sharpness, as well as the color begins to degrade within the original source. Its useful if you would like the extra input or perhaps the device you're connecting up only has composite video. Otherwise, use another factor, like component video. Sounds similar different.
