Review of Onkyo HT-S7800 5.1.2 Home Theater
Dolby Atmos was first presented at the famous Hollywood Dolby Theater cinema in April 2012. This format combines amulti-channel audio platform (channel-based audio bed) with anobject-oriented representation of sounds. Dolby Atmos is based onaudio objects instead of channels. The audio object is a sound sourcein each particular scene. For example, a crying baby, a helicopter ora car are classified as audio objects. This technology providesplacement and movement of specific sound effects throughout thescene, creating a very realistic and exciting sound atmosphere. Butthe maximum effect during playback is achieved when using ceilingacoustics.
The high level of competition in the home appliances segment forces the companies to actively use new technologies in its products. For example, 4K UltraHD and HDR are the most popular for the video. The market of audio systems is also susceptible to this trend. Today, 3D audio systems are most in demand. In 2017, companies offered а many models with support for Dolby Atmos and DTS: X formats, and today they are at the peak of popularity.
California Digital Theater System DTS announceda new DTS:X multi-channel sound format at CES 2015, and also, now is DTS-HD Master Audio. This format is also based on audio objects. Thereceiver determines their location in real time.
A special MDA Creator app creates sound in DTS: X format. In fact, it works as a plug-in to the editing program. MDA Creator determines the coordinates of the sound source and calculates the trajectory of its motion in three-dimensional space. Soundtracks in DTS: X format adapt to any configuration of acoustics.
These two formats have the following differences:
– the list of recommended acoustic configurations is absent in DTS and is present in Dolby;
– DTS: X has an additional option to control the volume of dialogs.
Today, these technologies are actively competing with each other.
