Want to have an amazing home theater system? You can get it at here. Sony has unveiled four home theater systems featuring the new S-AIR technology, Sony BRAVIA DAV-HDX576WF, Sony BRAVIA DAV-HDX277WC, Sony BRAVIA DAV-HDX279W, and Sony BRAVIA DAV-HDX275 systems. The S-AIR technology delivers a practical wireless multi-room solution without complicated set-up requirements, such as IP addresses, WEP keys and pin codes. Wireless audio can be transmitted from the main system in the living room to multiple rooms throughout the home — up to 164 feet — simply by connecting a separate S-AIR Air Station receiver/speaker into a power outlet. S-AIR technology also delivers audio wirelessly to rear surround speakers without interfering with other household devices.

The DAV-HDX576WF model includes one S-AIR Air Station receiver/speaker (AIR-SA10) and a wireless rear speaker kit (WAHT-SA10). The theater system offers height adjustable floor standing speakers designed to match the style and height of BRAVIA televisions. The DAV-HDX277WC model includes one S-AIR Air Station receiver/speaker (AIR-SA10) with an option to add a rear wireless speaker kit (WAHT-SA10, sold separately), while the DAV-HDX279W model includes the rear wireless speaker kit (WAHT-SA10) with an option to add S-AIR Air Station receiver/speakers for multi-room audio. And the DAV-HDX275 system is equipped with S-AIR-Ready technology with an option to add a rear wireless speaker kit (WHAT-SA10) and an S-AIR transmitter (EZW-T100) with S-AIR Air Stations (AIR-SA10).

The four BRAVIA® Theatre systems integrate a high-quality, five-disc DVD/CD player with upscaling to 1080p via HDMI? when connected to a 1080p-capable HDTV set. It features Sony’s Digital Media Port, an cradle for iPod players (TDM-iP10) that connects to the Digital Media Port to wirelessly stream audio through the house using S-AIR Air Stations, Digital Cinema Auto Calibration (DCAC) that offers simple multi-channel surround sound setup, Dialogue Audio Enhancer with night mode, and an updated Portable Audio Enhancer that improves the clarity and depth of a connected music player.

All of these are available now. The DAV-HDX576WF model costs about $500, the DAV-HDX277WC and DAV-HDX279W model cost about $400, and the DAV-HDX275 system costs about $300.
