Yamaha YSP-5100 Digital Sound Projector with HD Audio Decoding, 1080P-Compatible HDMI IntelliBeam, UniVolume and yAired Technology The Yamaha Sound bar is a single black bar 47.25 inches long. You can place it on your TV stand or with an optional bracket you can mount it on your wall. This single bar can produce 5 channel and 7 channel surround sound that you'd swear was coming from speakers placed all over the room.It's got four HDMI 1.3 inputs and one HDMI 1.3 output. It handles Blu-ray and DVD signals beautifully and if you watch a lot of television programming you'll love its UniVolume feature. It keeps commercials from blasting out at a higher volume than the program you're watching. The YSP-5100 applies this sophisticated technology to precisely control the orientation of the sound by focusing it through multiple beams. The center channel sound is heard directly, while sounds from other channels are heard after reflecting off walls. The result is true multi-channel surround sound that sounds just like a multi-speaker systembut without the need for extra speakers! Set up is easy. Once you've placed the unit, plug in the IntelliBeam microphone, place it in your listening position and the system "fingerprints" your room's acoustics. And speaking of beams, that's how the thing works. It contains 40 inch and a half (4 cm) speakers that together "beam" sounds to the exact right locations, taking into account the location of furniture, walls and other room characteristics. The Yamaha Sound-bar offers multiple surround sound decoders including DTS and Dolby Pro Logic IIx and it offers 11 Cinema DSP modes: three movie, three music and five entertainment. 5 And 7 Channel Audio From One Unit Multi-Channel/Single-Component Design
