The Sony BRAVIA XBR KDL-46XBR4 46-inch 1080p LCD Flat Panel HDTV continues Sony's tradition of making outstanding televisions. With a 46-inch screen, you'll be able to see every little detail without any need to squint. Sony does not hold back with any technologies, and the XBR series is its flagship line--so with the XBR, you know you'll get the best quality home theater experience available.

The XBR KDL-46XBR4 is a 1080p television with a full 1920 x 1080 resolution, the highest resolution available for the sharpest, clearest picture. The KDL-46XBR uses the most recent HDMI 1.3 interface, which houses both audio and video signals in one connector and has the bandwidth to support the data needed for the high resolution. Sony's Bravia Engine Pro Full Digital Video Processor upconverts all video signals to 1080p so you can watch all your old DVDs on this glorious display.
Sony complements the high resolution with the latest technology in color reproduction. The KDL-46XBR is a 10-bit display with 10-bit processing. Most panels are only 8-bit. The added bit depth here means a larger color palette for more faithful color reproduction and smoother transitions from one color to the next. Additionally, the display also supports the new x.v.Color standard, which dramatically increases the available color space. The end result is a picture that is so detailed, colorful, and vibrant, you'd have a hard time distinguishing it from real life.
The KDL-46XBR4 features Sony's Motionflow technology, which automatically adjusts for and applies the proper processing for optimal motion reproduction depending on the video input. This includes support for 24 frames per second (24p) video, which displays video content at the 24-frames-per-second rate at which it was originally filmed or recorded. With 24p, you get the most faithful possible reproduction of the original.
A Wide Variety of Inputs
This Sony television's wide variety of inputs ensures compatibility with your other home theater components. There are three HDMI connections for Blu-Ray, HD DVD, and other technologies requiring the high bandwidth, and two component video inputs, three composite video inputs, one S-Video input, one PC Audio and Video input, and five analog audio inputs. Even with a collection of legacy components, you shouldn't have a problem connecting to the KDL-46XBR4.
Stunning Looks
The KDL-46XBR4 not only displays stunning video but is itself a head-turner. It features Sony's unique floating glass frame along with a black bezel that can be interchanged with optional color bezels to match the display to your decor.
Outstanding Ergonomics and Simplicity of Control
Sony's Xross Media Bar interface is an award-winning, intuitive on-screen display that makes setup a breeze, with menus and controls logically laid out for quick access. The KDL-46XBR4 also features Theatre Sync technology, based on the HDMI-CEC standard, which means you can easily connect to and control compatible devices. For example, when the KDL-46XBR4 is connected to a compatible DVD player, you can turn on both the DVD player and the television and start playing a DVD with a single push of a button on the remote. When you're done, another push of a button powers everything down. With Theatre Sync, you can spend time enjoying the movie rather than waste time setting everything up.
More Than Just a Television
Because more and more people expect to view photos on their HDTVs, Sony developed a Photo TV HD mode that optimally sets the sharpness, gradation, and color to make digital photos look like printed photography.
The KDL-46XBR4 is backed by a 1-year limited warranty for parts and labor.

Customer Review: Terrific Television
We are very pleased with this television. After exhaustive research, we are very happy that we purchased the SONY at such a great price.
Customer Review: Sony XBR4 46 inch TV Great Picture & Looks Great OFF too.
This Sony TV Has a Beautiful Picture from ALL Sources. I have cable and a upconverting DVD. The picture is astounding in clarity and detail! I Like Everything about this TV, the Picture, the Lighted Remote, the Multiple Menues for adjusting Every Aspect of the Picture and Sound. I am very satisfied with the sound without a Home Theater System. Too me another Important issue is that this TV Looks Stunning when it is turned OFF! I love the design with the Floating Glass Frame. It is Much Better looking than the Newer Xbr's that came on the market in 2008. I ordered this on a Sat. and it was Delivered on Wed. in 3 Bus. days and that was with FREE Shipping from Butterfly Photo thru Amazon. I also got the best price I have seen on a NEW set of this model so far. Great Job Sony, Amazon, and Butterfly Photo!! Very Happy.
Soundproofing is the action taken to reduce the intensity of sound with respect to the receiver. The receiver can refer to a human, a listening or recording device or a piece of sensitive equipment affected by sound waves and their subsequent vibrations. The degree of soundproofing depends on the sensitivity of the receiver and its proximity to the source of the sound.
There are several different techniques that can be implemented when soundproofing. These include:
- PASSIVE TECHNIQUES
- Noise barriers
- Acoustic insulators
- Vibration dampers
- ACTIVE TECHNIQUES
- Anti-noise sound generators and interference cancellations
PASSIVE TECHNIQUES
Noise barriers are often seen adorning the highways and train lines of major cities. Their primary purpose is to mitigate the amount of noise pollution caused by the constant stream of traffic by deflecting the sound away from the urban population. These barriers are constructed from high density materials like cement or SDS (sound deadening steel) which also absorbs some of the sound.
Acoustic insulators confine noise within the insulated area. Record producers make use of this technique within their studio rooms to prevent 'bleed' from instruments between rooms. Many home theater systems utilize acoustic insulation to 'trap' the sounds within the theater space with the intention of enhancing the audio/visual experience.
Vibration damping is the most common form of treating unwanted mechanical noise. Aside from the obtrusive implications of unwanted noise pollution, vibration can cause irreparable damage to structures due to crack propagation from stress fatigue. Vibration dampers are elastic in their physical make up, allowing them to 'move with the mechanics' of the overall system and generally speaking, the more elastic a damper is, the more effective it will be at reducing the system's oscillations. Rubber pads or coil springs are excellent vibration dampers.
ACTIVE TECHNIQUES
Soundproofing using the active method employs the use of anti-noise devices which emit a pressure wave at the same amplitude, but exactly out of phase with the sound source, canceling each other out. What this suggests is the natural 'mountain valley' cycles of a wave are exactly opposite to each other; (I.E. when the initial source wave is in 'mountain phase' the anti-noise device will be in its 'valley phase'.) Once the two waves combine, they rescind each other back to a state of equilibrium. White noise devices, (which are analogous to white light in that they contain all the frequencies of the audio spectrum) perform noise cancellations by emitting a slight static buzz, which can sound very similar to rain, or the ocean, but that actively neutralizes any sound waves operating at the same amplitude.
