[Ryosaku x Ryojin of Torii Kazuto] Surprising home theater new style! "Hathaway" in Sony "HT -A9" --AV Watch

Achieves up to 12ch surround playback with four wireless speakers

The home theater has a variety of styles, from simple systems such as sound bars to full -fledged systems consisting of single speakers and AV amplifiers.A full -fledged system tends to be shunned because it is difficult to install multiple devices (especially the rear or ceiling speakers), but the sound that supports the latest three -dimensional sound called imaging audio like Dolby Atmos.At the bar, the number of models that can add rear speakers as options is increasing.The full -fledged system with a single item component has not changed for a long time, but it is not satisfactory with an easy -to -use soundbar, so that more and more people are looking for both easy and full -fledged three -dimensional sound.。

A home theater device for you was born.That is Sony's "HT-A9" (actual sold about 220,000 yen).A home theater system that is a set of four wireless speakers and control boxes.Wireless speakers are now popular items as easy audio, with small speakers for smartphones, as well as Wi-Fi, and have full-fledged wireless speakers that can support video distribution services and high-resolution playback.

Of course, even in the home theater, there is a standard "WISA" that can use a 5GHz band wireless radio wave to transmit up to 8ch signals by non -compression, and some manufacturers have released speakers corresponding.Although it is necessary to connect the power to each speaker, the hurdle when installing it in the living room is considerably lower because there is no need to draw the wiring for each speaker.It is a freshly born standard, but this seems to be quite expected.

Under such circumstances, Sony has developed a unique technology called "360 Spatial Sound Mapping", which reproduces up to 12ch virtual speakers with four wireless speakers, and has been installed in a system called HT-A9.Because it is up to 12ch, ATMOS can play a 7.1.4ch configuration.The number of channels for surround playback is enough.Moreover, as a home theater system, it is commercialized as a set of four wireless speakers and control units, so there is no need to bother your head by choosing a product, and each speaker has been paired at the time of shipment.In other words, it has been realized that it is OK just by connecting each to the power supply.This is a very groundbreaking new technology.I decided to try that ability right away.
