The home theater
Want to cinema? Today it is no longer necessary to go to a cinema room to experience the strong emotions that arouses the vision of a film on the big screen, since it is possible to set up in its living room facilities able to guarantee the maximum technological comfort. You just have to have the appropriate quality and size images associated with flawless sound reproduction.
And all this is made possible by compact and uncluttered systems, with a sophisticated and particular design, capable of creating a refined and technological space within the living room. The Home theatre facilities, an Anglo-Saxon definition that stands for “home Cinema”, originated in the United States with the first surround systems of the 80, which offered cinema enthusiasts the chance to enjoy the film and its sound effects, no longer Just as viewers in front of a screen. Today, there are 124 million European families who have a VCR, plus 5.5 million of DVD players.
Home Theater : Best Home Entertainment
The European homevideo market is a growing reality: in 2001, the per capita spending on home video has exceeded that of cinema consumption in the room and is superior to all other kinds of entertainment. The Home Theater system is divided into two sections, one for the reproduction of audio signals and the other for the reproduction of video signals.
The first one includes TVs, video projectors, or rear projectors, second amplifier-decoder and speakers. The two traditional stereo channels for movie sound reproduction are replaced by a higher number of loudspeakers, also placed behind the listening point. This allows the spectator to surround with the sound, increasing its involvement in the vision.
Increasingly large screens
The Home Theatre system first includes a display, the size of which should depend on the distance from the viewing point. With normal TV signals, the distance should be about 6-7 times the height of the screen itself. With regard to the typology, the common tube TVs probably guarantee the best image quality in relation to the price, but they offer a useful image of a size not exceeding 36 “diagonal. The size increases by using the backlighters and plasma or LCD screens. Increasingly large and subtle, the latter guarantee colors, images and lights that are true to reality, presenting themselves as real design objects.
Beovision 5, designed by David Lewis for the Bang & Olufsen brand, looks like a 16: 9 ultra-thin screen technology and a frame available in aluminum, black, green, blue and red. You can hang it as a frame or mount it on the wall as a complement to the furniture, using a support with a tilt of 9 °.
When powered on, a sensor manages the Automatic Picture Control function to adjust the ambient light and control the brightness of the screen, equipped with an anti-reflective coating. The home theater system incorporates the Dolby Digital system to fully utilize the 5.1 multichannel surround sound playback of the latest DVDs.
Increasingly bigger picture
By leveraging digital technology in finding innovative entertainment solutions, Pioneer has created the new 50-inch plasma PDP-503HDE television, one of the largest screens currently available. Spectacular to the eye, it dominates the space in which it is placed and encloses in 9.8 cm thick, innovative features and extreme ease of use: it comes with low-tuner, progressive 100Hz tuner, speakers and features teletext, dual screen and on screen display.
The analog tuner can play all terrestrial TV channels, but it can also handle other external sources such as satellite decoders, video DVDs, video recorders, video cameras and consoles. The new Pure Color filter significantly diminishes the reflection of outdoor light and increases contrast even with direct exposure to sunlight, while plasma cells, thanks to the exclusive Deep Waffle Rib technology, increase the brightness level by 60% compared to the previous 50 inch model.
The video projector is the ideal TV set for those who want a great image format: video projection technology has now come to an excellent stage of evolution thanks to the Texas Instruments DLP technology, which uses a particular chip called DMD ( digital micromirror device), consisting of adjustable microspeakers that allow light to be reflected depending on how the pixels that make up the image are to be drawn.
Small and compact, the Sim2 Grand Cinema range projectors incorporate the best technology in a chassis weighing only five pounds, to bring our own room-to-living movie theater. Based on the new DMD chip, the HT300 offers a native 720p resolution for a high definition image. Accuracy in color reproduction plays a key role in creating a cinematic image. The optical path has been redesigned to further enhance the black level and depth of field, up to a true> 1000: 1 contrast ratio.
A new six-segment color wheel, increasing the frequency of colored segments, dramatically reduces the effect of color separation (commonly known as “rainbow effect”), which is visible only by a small percentage of people. The lens with a long throw ratio allows you to not place the projector between the viewer and the screen, but instead place it on a bookcase or ceiling on the opposite side of the screen, while the double adjustment of the trapezium effect ensures a mechanical-optical correction of 16 ° to get a perfectly rectangular image without any artifacts. If the ceilings are very high, you can use the remote control for digital correction.
Video recorders and laserdisc players
The source of audio-video signals is the main element to be provided in the establishment of a Home Theatre facility. The main audio-video source is the DVD player, which allows you to get the maximum performance from modern installations. The audio-video standard used on the DVD represents the best performance achievable for the home environment.
It is preferable to purchase newly produced models, equipped with sophisticated electronic circuits, DTS (multi-channel digital audio) and the ability to read burned CD ROMs. Among other types of audio-video sources are digital satellite channels, the Laserdisc player, which plays CD-video with analog audio and video and the VHS VCR, useful for recording programs from the television band if you do not own a recordable DVD.
All in one home entertainment
On the market are also available devices that integrate DVD player, amplifier, decoder and radio tuner, or that associate DVD player and color TV. Also the DVD player can have the integrated audio decoder: In this case it is imperative that the amplifier-decoder has already separate analog multi-channel inputs, to allow the signals already decoded to be received by the amplifier, amplified and Sent to the crates. One example is the two systems “all in one” ns-DV77 and NS-DV88 Pioneer. Both ultra compact home theatre systems are well suited to the current trends of taste to the needs of rationality and technological simplicity.
The novelty that characterizes them is the ability to play MP3 files recorded on CD and the ease of management of these files, guaranteed by the function mp3 Navigator. The integrated decoder DTS, Dolby Digital and Dolby ProLogic can satisfy all film enthusiasts, who can enjoy the multichannel sound thanks to the reproduction of the medium-high frequencies from the 5 satellite speakers from 40 watts each and the power of Guaranteed by the 65w subwoofer. The new DVD player is compatible with CD, CD-R/RW and Video CD.
The separate dot matrix display, whose brightness can be adjusted as you prefer, displays the information in an extremely clear manner, while the pre-programmed remote control provides access to all functions of the system. To ensure perfect adaptability to any type of environment, the new generation NS, albeit based on a single technology, is available in two versions: silver, gritty and trendy; or light wood, warm and elegant. The systems can be completed with a cassette recorder.
Home Theatre Systems, choose quality: Plant arrangement
The time to arrange the various components of a Home Theatre plant, it is advisable to follow some steps to obtain a satisfactory performance from the entire system. Too many surfaces discovered can create phenomena of reflection of the sound, ovviabili using carpets, curtains or paintings.
It is preferable to avoid spaces that are perfectly square or have a double size compared to each other, to avoid resonances. The listening area should be centered between the two walls where the surround speakers will be placed. The display, especially if it is a TV, should have a position that avoids reflections on the screen, and therefore should be placed in a central area of the wall, with the sound box of the central channel placed just above or below it and behind the Projector screen.
The two front speakers, at the sides of the screen and equidistant from it, must be placed in such a way as to obtain a perfect symmetry with respect to the spectator and so that the joining between the listening point and the two speakers form an angle of approximately 60 °. The same suggestions apply to the rear speakers, which must be positioned at the sides of the listening point, if possible slightly backwards and a few centimetres above the spectator’s head. The subwoofer is the speaker that has fewer problems in positioning, since the human ear does not distinguish which direction the bass comes from. However, it is important that it is not positioned in the corners of the room, to avoid annoying rumble.
