Before we go on, sure many will be thinking that there are other solutions to mount a home cinema,

A few weeks ago we saw how modern flat TVs have poor sound quality, or at least not good enough golden screen cinemas to enjoy an authentic golden screen cinemas "theater sound" at home.
If we want a similar sound experience and even superior to that offered by commercial cinemas golden screen cinemas at least we must resort to an A / V receiver plus a set of quality speakers. In this article we will see what these devices are, what they are, what their main features and how they help us get a great sound in our homes.
Before we go on, sure many will be thinking that there are other solutions to mount a home cinema, such as sound bars, kits and even multichannel audio sound processors and separate amplification stages on the market.
Indeed, all of these teams exist, although in this first article we will focus on A / V receivers more speakers, since the quality they provide us is usually quite higher than that obtained by the sound bars and multi channel kits (which many fans considered as options of last resort) while they are easier to configure and generally cheaper than modular solutions (processors, power amplifiers, amplifiers, equalizers, etc..).
Any system of passive speakers we install at home requires an amplifier (no speaker models that have incorporated are denominated assets) to provide transducers needed to produce the sound pressure required by the user power is what known as power amp.
But before producing output signals is necessary to pass a preamp stage to adapt the electrical input levels golden screen cinemas to appropriate values for processing. Subsequently, the power raises the millivolts golden screen cinemas that gives the volt preamp to generate the necessary golden screen cinemas watts to move the loudspeaker diaphragm. Receivers A / V integrated under its housing both stages, life simplificándonos users. golden screen cinemas
The next big primary receptor function A / V is to serve as a center for receiving and processing the audio and video playback of different sources we have at home (DVD, Blu-Ray, CD player, TV, game console , PC, etc.). both analog and digital golden screen cinemas formats.
For this purpose, often have many connections in the back (and also some auxiliary in the front), both analog and digital, allowing us to connect different devices to it and select at each time you want to listen.
Moreover, as the films today often have digital multichannel audio, we need a team that is capable of decoding the digital information and transform analog signals into understandable electronics speakers. This is the next essential task of all A / V receiver modern, which is responsible for receiving the binary data from audio tracks from our DVD s, Blu-Rays or digital files in formats such Doby Digital, DTS, etc.. and you decode to analog signals.
Summing up a bit this first section, we can say that A / V receivers integrated into a single device the preamp stage, the digital decoder and processor of multi-channel audio, the digital signal processor (both audio and video) and stages power (one for each speaker), reducing costs and simplifying the management of these systems. Receivers A / V: processing of multichannel audio
Receivers A / V today are able not only to vary the tonal balance of bass and treble as did the typical stereos few decades ago, but also to perform complex golden screen cinemas signal processing operations that allow us to adjust manually and / or automatic temporal and frequency response of our speakers.
Beginning with a classic and very useful features, modern receivers allow us to signal filtering based on the "size" or rather the frequential capacities of speakers you have installed. Thus we can select which speakers are capable of reproducing golden screen cinemas bass frequencies and which are not, indicating the cutoff point at which the audio signal will be redirected to the subwoofer or speaker designed golden screen cinemas specifically for low frequency reproduction.
Receivers A / V allow us to set cutoff frequency high pass (or low-pass, depending how you look) best suited to the conditions of our speakers and our room, usually both automatically (through acoustic correction systems we'll see later) and manual permitiénd
