AV Receiver - Heart Of one's Property Theater

By Carlos Howard


Audio Video Receivers are the heart of any home theater systems. They are fundamentally amplifiers that will amplify sound from different sources. Most AV receivers have multiple amplifiers for best results. They are able to take input from numerous sources like Blue Ray devices, DVD players, gaming consoles like Ps3, Television boxes etc. They can route the video you want to your Tv and method, amplify and send the audio for your speakers.

Distinction Between Stereo and AV receivers

Stereos can send sound output to only two channels namely left and proper and occasionally to the sub-woofer. Audio video receivers, also identified sometimes by the name of 5.1 receiver, can send the audio output to five or far more speakers. Much more advanced receivers can do up to 9 speakers.

The primary functions of AV receivers are briefly discussed below:

Decoders They are identified to have capability to decode sound i.e. process the sound. For instance, a they can obtain a 2 channel sound but send it to 5 distinct channels to generate surround impact.

DSP impact They can also manipulate sound to produce different effects, including equalization and field simulations like "concert", "hall" etc.

Video upconvertion This is usually called upconvertion or transcoding. They can convert videos from 1 format to the other. As an example, a AV receiver can convert a 480 pixels video(480 lines per frame) to 720 pixels video(720 lines per frame and also modify a component video to s-video. For men and women with incompatible devices, a AV receiver can be quite beneficial.

Amplification Last but not the least, amplification. Audio video receivers amply various channels of sound that may be send to individual speakers. A 5.1 amplifier can send sound to a center speaker, left front and correct front speaker, rear left and rear proper speakers. All of these channels are amplified individually.

Top quality receiver gives quite much less distortion of sound providing as clear sound as possible. Therefore even though acquiring a receiver you need to always consider its distortion level. Distortion much less than.1% are actually unnoticeable so attempt not to get the ones with distortion level far more than 0.1%. Louder the sound necessary more amplification is necessary, meaning a lot more energy is utilised by the amplifier.
