installation of a home theater system

When do I have to consider when installing a home theater system? The question is often asked. We try to help get you going with a few tips and concerns.

The room : The room in which the home theater system will be placed is often overlooked as a factor in the installation. Different aspects of a room influence.

Let us first at the image quality of your television. Light sources play a role: both natural and artificial light. The natural light during the day we can try to keep with the right choice of curtains, the dark type. Still, we need a bit of light in space, if only to find the remote control, or even to sip from the glass. The lights with low wattage are best for a corner or on a wall designed to thus provide indirect light. A passing is even better: dim when the movie starts.

The shape of the space also plays a role, and this in auditory area:

  • Rectangular space : This is the ideal form for a perfect speaker placement. Place the TV on one of the short sides and your sofa in the middle of the room.
  • Square room : Not so ideal. Unless the room is huge, the listening position will be pushed by the shape of the space on the back wall. Place the surround speakers on the back wall in the corners.
  • L shape : These areas suffer sometimes a strange bass. We recommend you to consider the smaller space in the L road and continue the installation as if it were a rectangular space.

The rear speakers are best placed at an equal distance from the seat or sofa. They should also be placed slightly to the rear.

The manual included or incorporated menu, by the way often gives a good visual support for the placement of the speakers. Attach them to the wall or partition, then you give them best points a bit down to the seat.

When you put the cables, keep some rope over to the end. So you still give some leeway in positioning the speakers. Do the same on the other side of the system. If your speakers are floor models, buy or take over a support underneath. The center speaker gets a place at or below the television.

The last speaker that you place the sub woofer. This speaker allows for the reproduction of bass like explosions and other special effects. Here we can distinguish two types: passive and active. The latter requires its own power source which makes this sub woofer should have a place close to a power outlet.

Now the speaker wiring is completed, the fun part comes in: connecting the various devices. Therefore you have the choice of different cables whose quality differs thoroughly.

The cables are supplied with most speakers of a lesser quality and not make the most of your installation.

High-end AV cables are thicker (and more expensive) than normal cables but they have a much better response and less signal loss. Especially in the case they are recommended somewhat more expensive equipment.

Invest in a decent pair cables often means a real transformation of your equipment and chain. It would be a shame a lot of money to fork out for the instruments and to come home with a thin cable that does not use all the capabilities of your system.

In these more expensive cables is also the length of interest. The longer the cable, the greater the price tag will be. Therefore, measuring the length between the different components that need to be connected.

Most cables for home theater sets are colored: red for right audio, white for left audio and yellow for video. With all-in-one-box systems have the cables and place them in need plugs the same color. This should make it easier to install a piece.

The different cables in a row, in order of quality (best to less):

HDMI (high-definition digital audio and HD video)
This is a recent type of cable to the main unit of the home theater system connects to the television, in particular LCD TV or plasma TV. HDMI stands for High Definition Multimedia Interface.

The 19-pin connector has become the standard for AV equipment. As for television, DVD players and games consoles has taken over the function of the scart cable; with regard to noise replaces the optical or coaxial digital connections.

An HDMI cable transfers digital audio and video between the different devices. As a result, in theory, the connection of the different components much easier. Over a single HDMI cable to multi-channel audio and high definition televisions are sent. Of course this requires your flat features an HDMI connection.

More so, you can at a later date yet to connect other devices with multiple HDMI inputs, such as a game console. Who only has one HDMI input has to be flat can be happy even called a switch box purchases where you let transmit all HDMI cables and then connect to that one HDMI input.

Different versions of HDMI
As with USB, there are different versions of HDMI. The version used almost standard today is HDMI version 1.3. This specification provides several improvements over the older versions such as more accurate color reproduction (over one billion colors), high bandwidth (for the transmission of more colors and HD audio) and Auto Lip Sync, allowing video and audio sync through all devices.

HDMI will like USB continue to develop, but for now you’re with HDMI 1.3 the following years safely.

Scart (analog audio and video) : This cable handles both video signals both (composite, RGB, S-Video and Component Video) and audio signals.

Component video (analog HD video) : This is a specialized type of connection that provides excellent image quality, and should not be inferior to HDMI. The video information is divided into three separate signals, two for color and one for luminance or brightness.

The cable consists of three RCA jacks which are also referred to as Y (green indicator), Pb (blue indicator) and Pr red indicator). Component Video is better than S-Video.

S-Video (Analog Video) : S-Video is the best connection when component video and HDMI are not available. The video signal is split into two parts, one for color and one for brightness.

That should provide finer detail and higher resolution of the image. The sharpness of the pictures is better than composite video.

Composite video (analog video) : For composite video signals, the brightness (luminance) and color (chrominance) of the image combined in one cable.

The image quality is less because they interact, and may cause noise and interference.

Optical Digital (digital audio) : S / PDIF stands for Sony / Philips Digital InterFace and a digital connection between various components to transmit audio. Example, you can connect the digital audio output from a DVD player or set-top box with an AV amplifier. Of S / PDIF, there is a coaxial optical version and a version.

The optical version, often called Toslink, uses pulses of red light to send audio through. The coaxial version uses copper wires.

RCA : This connector you know of RCA connectors, with red for audio left, right and white for audio and yellow for video.
