Everything You Need To Know About Home Theatre Receivers

o The brain and nerve center of your system.

Receiver, many different important functions in your system. In addition to ensure audio and video switching station, the audio signal processing and amplification, hearing, and in some high-end models, upconversion of standard video signals for high definition by the component video or HDMI output. Other features can be found be found on the receiver ports for connecting an antenna XM satellite radio or iPod.Since the receiver is an essential element, it is important to do your homework and choose the record sufficient evidence and output connections to all your audio and video sources offers.

No stereo, 5.1, 6.1 and 7.1-channel receiver declares

Each receiver can handle reading a two-channel stereo, but a basic model should also cases, most equipped with Dolby Digital and DTS surround-sound treatment – a digital track found alternativeon some DVDs. Both formats use five discrete audio channels and a special low frequency (bass) Effects-channel sources provide immersive, cinema-quality sound in near DVD or HDTV. Most recipients step add Dolby Digital EX and DTS ES treatment. These methods use an additional "return" channel surround sound with DTS further expand the capabilities of Dolby Digital and also.

othe most common type of receiver and 5.1-channel Model-encode the audio in Dolby Digital and DTS information contained and transmitted to the left and right front, center and surround system through their top five channels of amplification. (The .1, or the impact of low frequency channel in a movie soundtrack is the guided amplifier, a subwoofer powered by its own board.)

oAlong provide all the functions of a receiver, 5.1-channel, channel-amp-models include 6.1, the additional > A chain driving the rear surround speakers when playing DVD soundtrack encoded in Dolby Digital EX or DTS-ES. The main advantage of the surround back channel is that it creates an even more realistic surround sound experience – one that well at the next, is what you hear in a theater equipped.

O7.1 receiver channels are basically the same as the 6.1-channel models, but they are yet another amp channel to the second drive Surround BackSpeakers>. In this case, the audio information, the two rear speakers are identical, it is divided between the two rear speakers to create an even larger scope of his back. The specifications for the new HD-DVD and Blu-ray offers up to 7.1 discrete tracks of audio channels. Thus, while the receiver A-Channel 7.1 may seem exaggerated, there is now an option to test more than 5.1 and 6.1 models.

No audio formats – Dolby Digital, DTSTHX and Dolby Headphone explained

As in stereo, 5.1 shown, 6.1 and 7.1 surround said, Dolby Digital and Dolby Digital EX and DTS-ES and DTS Surround Sound audio main modes on the base and step-up receiver found. But the high-end models may offer more types of treatment. For example, some have THX-certified receivers called THX Surround EX. This method works with Dolby Digital EX processing time-align a pair of rear surround speakers in aSystem 7.1-channel and the associated noise to the other speakers in the system. The end result is more homogeneous, like in the movies encoded surround when watching DVD presentation with a soundtrack Dolby Digital EX. And then there's Dolby Headphone, a treatment that headset brings the dynamism, clarity of dialogue and spatial effects of 5.1-channel Dolby Digital stereo. Even if you use a headset, like in a fully equipped home theater seem strangeis a great option for the disturbing late at night unless you want others in the house.

No configuration of the receiver base.

Setting the base receiver includes connection of video and audio sources and run the wire from the back of the speaker unit "of input ports. Most DVD players, CD changers, satellite receivers and cable boxes to available digital audio output with a series of regular analog output jacks. You will usually sound better when you use the digital audioContext and an absolute necessity in order to experience 5.1-channel digital audio on DVD or HDTV program. The rules for the installation of video receivers are almost the same as those for audio. If your video source has a digital DVI or HDMI (and the receiver provides digital video switching), it will give a better performance than analog component video, composite and S-Video connectors.

oSpeakers.

The sound from the receiver mustdistributed according to the capabilities of the loudspeakers used in the system. To accomplish this effectively, get a speaker setup menu, you can specify the size of each speaker in the system as large and small, and whether you have a subwoofer. The settings you in the performance of the bass management, the precise frequency at which the audio signals are filtered by low interest groups and to the subwoofer (or the main speakers when a determinedSubwoofer is not used). The next step is to measure the duration of the speaker to your seat, and give the distance in the setup menu. This allows recipients to perform time alignment – essentially adding a slight delay for the audio channels to a more consistent surround sound effect. And the final configuration task is to balance system, the volume of each speaker in the. This ensures that the sound of all those involved is equally strong – an important step forDialogue flexible and realistic surround sound environment. Some receivers have the job automatically, in others you have built a certain level of sound pressure to use with the receiver's test tones manually configure settings.

o How many watts per channel?

The amount of energy you need a receiver is determined by two factors: room size, and performance of the speakers that you pair with. An average consumption of a receiver of 100Watts per channel. This level should be enough juice for a small or medium-sized (80-200 square meters) home cinema with an additional subwoofer satellite speaker system for five years. But large tower speakers – particularly those who use the technologies, such as exotic magnetic or electrostatic air pilots – may require more amplifier power to the receiver handle noise peaks in an action movie with a string of 100 watts of – offer.

o Make the most of your receiver andSystem

Because a receiver is the brain of the system, you should try to maximize its features to make life easier and more enjoyable. At least you will want from their functions loop tape drive signals to a CD-ROM or DVD recorder or VCR benefit for the recording of audio and video database. Many high-end models also offer a multi-zone audio output that allows you to direct music in stereo or radio in an adjacent room as a dining room or kitchen.

oRoom Auto-EQSystems

A new feature on some receivers, the automatic realignment or Auto-EQ. Although this feature varies from receiver to receiver, it is to improve the sound quality to compensate, in general, by automatically adjusting the settings, such as crossing points of the speakers. EQ can car also adjust bass and treble for different audio channels to problems with the room acoustics . Receiver with Auto-EQ usually with a small microphone that is used for initial configuration come. Receivermakes the test tones from each speaker in sequence while the microphone takes sound and give feedback. This information is then used to automatically speaker levels, the distance parameters of the housing, and various EQ and room correction functions.

oReceiver or separate preamp / processor and amplifier

Buy a receiver is to be bundled with all the extras by far the easiest way to start when developing a home theater. But itDisadvantages of this approach. Farce many electronic components such as a preamp / processor, multi-channel amplifier and a radio tuner and increase in a single chassis, the level of background noise, why purists, is to buy the components separately rather. With new innovations in home theater with a Buy arrival rate ultra-fast, separate components also gives you insurance against aging – you can update your preamp / processor without buying a new amplifier andvice versa.
