AV receiver with Dolby Atmos for the cinema feeling at home

An AV receiver with Dolby Atmos represents a device with high-quality 3 D audio format. Thanks to this feature, home theater rooms convince with one of the key qualities of large cinema halls.


AV receivers with Dolby Atmos

Dolby Atmos

Dolby Atmos is a specific form of surround sound from Dolby Laboratories, which has been on the market for several years.
This application is known mainly from cinemas, where this standard is widely used. For example, Dolby Atmos is one of the two components of Dolby Cinema.
Dolby Cinema is a new concept that takes the approach of revolutionizing the cinema experience. Specifically, it uses new sound and image concepts. In addition to being used as a modification in smartphones, Dolby Atmos is being applied to AV receivers.
Dolby Atmos is downward compatible, meaning it can be used for 5.1 or 7.1, for example. The format meets with wide acceptance in the cinema landscape. Initially, existing films were subsequently mixed into Dolby Atmos.
After the format gradually became established, however, films were mixed directly into Dolby Atmos. In principle, Dolby Atmos as a new system is technologically above the predecessor systems 7.1 or 5.1.
However, the sound can be derived for these simpler systems. The integration of the technology first took place in commercial cinemas. In the course of this process, Dolby Atmos increasingly found its way into private home theaters.


Advantages of an AV receiver with Dolby Atmos

The name Dolby Atmos stands for a special audio quality. To be emphasized with an AV receiver with Dolby Atmos is the interaction between AV receiver and loudspeaker.
For example, the 5.1 system has a finite number of speakers, in this case there are 5 of them.
Each of these speakers outputs the same sound. The big difference between Dolby Atmos and predecessor systems represents the way the sound is handled.
An AV receiver with Dolby Atmos can assign a specific sound to each speaker. AV receiver users benefit immensely from Dolby Atmos.
This allows the number of speakers to be increased. In other words, speakers can be placed on the ceiling that can realistically reproduce an approaching storm front.
There are special ceiling speakers on the market that are suitable for the reproduced sound objects in the upper listening area of the home theater room. In addition, front or surround speakers can also be installed.

In principle, the possibility of installing speakers is infinite. The listening room corresponds to the cinema room. In this room, sound objects can be positioned in different places. For this reason, the use of additional boxes is relevant and thus more authentic sound output. The following situation: Inside a Blu-Ray player there is a DVD in Dolby Atmos mix. In addition, the TV set could play this format. Only and only the AV receiver is not able to play Dolby Atmos. In this case, the AVR handles the output of the sound in downward-compatible surround sound. It is therefore possible to play Blue-Ray DVDs in Dolby Atmos format via an AV receiver without the corresponding configuration. In contrast, an AV receiver with Dolby Atmos provides the optimal surround sound.


Role of the speakers for Dolby Atmos

In the context of Dolby Atmos, the number of speakers plays a central role, as does their subsequent positioning. Dobly Atmos combinations have different manifestations. One possible form is represented by the common 5.1 system.
Another variation is for example the 5.1.2 surround system. Here, the last number stands for the sum of the individual ceiling speakers. Two pairs of height speakers are also possible, resulting in a 5.1.4 surround system.
An indispensable prerequisite for the use of the 3 D format is the basic ability of the AV receiver to play the audio format. In addition, the sum of the speakers in the home theater room determines the required AV receiver. Thus, if you want to serve 11 channels, you need an 11-channel AV receiver.
