Sony is introducing eight new audio/video receivers for enthusiasts looking for performance and flexibility. The company is continuing to extend its line of 24-and 32-bit Digital Steam Processors to deliver high quality, multichannel surround sound to consumers.The two-phase process starts with the decoding of DolbyÆ Digital and DTSÆ Digital Surround with the 24-bit DSP chip. Then, the signal is sent to a separate chip where Sony applies its Digital Cinema Sound system to a high performance 32-bit processor. The result, claims Sony, is multichannel surround sound with improved resolution and detail.Sony is also continuing its expansion of the Digital Cinema Sound system, which Sony says replicates the acoustic environments from the post-production dubbing stages at Sony Pictures Entertainment by adding new levels of depth and clarity. The DCS system also has virtual 3D technology, giving users ""virtual"" multiple rear speakers, creating what Sony describes as a more theatre-like environment in the home.These features can be found in five of Sonyís newest receivers, ranging from the STR-DE825 ($480 MSRP) to the STR-DA777ES ($1,499 MSRP), which employs 24-bit decoding and two 32-bit DSP engines dedicated to DCS processing.The STR-DA777ES and STR-DE935 also offer multi-room capability, providing users with independent source selection in a second room.Five models in the lineup of A/V receivers feature Dolby Digital and DTS Digital Surround decoding utilizing 24-bit plus 32-bit DSP.
