THE ROOM

It is important to consider what kind of room should operate for a Board of Home Theater. We can use a family room for this purpose, but we must take into account several points in order to know how viable it is. The issues that we discuss are:

Form: It is recommended that this should be rectangular, which is preferably quarter closed. If not possibly be closed search that has closed as much as possible. That both the sound and by the entry of light.
   
Finishing: It is recommended that the walls, ceiling and floor are of spongy material, to avoid bouncing sound and dark colors or medium dark to avoid the reflection of light.

In the case of a family room you should probably give priority to the sight of your room, but consider these points.

If it is a question of a dedicated quarter(room) there is recommended that the walls should be covered insulating acoustic material and that the color is in dark colors or at least in average colors, so that it does not bounce the light.

SEATS

The type of seating is important not only for comfortable, but also that seat should not as such that you will fall asleep.

If you have a room where 2 or more rows of seats can be adjusted, this should be considered when choosing both the seats, as in the position of the screen, the distance between rows.

The second row will have to be 30 cm overhead of the level of the first one, handling for this 2 steps.

Hi-fi system team work:

Currently on the market there is endless number of audio and video equipment that offer home theater. The features suggest that these teams are as follows:

Audio speakers:

The team should be multi channel, that is to handle 6 speakers, (central, 2 front side, 2 rear side and active subwoofer which has an integrated amplifier,

This is known as 5.1, 6.1 or 7.1. If room size 4x4 meters or less the 5.1 audio system is adequate, it is recommended only 6.1 or 7.1 when the room is large and with enough space behind the seats, the speakers for surround back.

Also check that the computer has digital audio inputs, as well as the DVD player that handles digital audio output, preferably by optical fiber.

Video (player):

There is needed a DVD player, that handles video output component and progressive scan, and if the projector or screen handles Digital entry HDMI or DVI-D, comes with a DVD player to take this exit, consider this equipment and cables are expensive.    

HDMI digital video

Video (Display / projector):

If it is a dedicated room or whether it can control lighting in the room to achieve total darkness or twilight high, our recommendation is a projector with a projection screen, which typically can make a projection of 100 or 120 inches diagonally. But if this is not possible, plasma screens or rear projection TVs are options for ambient light conditions.

In both cases, it is important that the team handled a resolution of 1280x720 pixels, and in Wide Screen, it is recommended conventional projectors for home theater used to be dedicated.

Now a days emerging market much as projectors and screens with 1920x1080 resolution, known as full HD, this is the maximum resolution that will be handled in the systems of both high-definition digital TV as the new high definition Blu-ray Disc (also known as Blu-ray or BD) players with HD DVD that are emerging on the market at the end of this year.

Placement

The placement of the Speaker is an important point to consider, as this will depend on which of us really sound the surround effect of multi-channel equipment.

Currently, most films are recorded with 5.1-channel, so the 7.1 channels have only recommend it for large rooms where there is enough space behind the place where people feel.

The central Speaker: must be below or above the screen or monitor, in the case of projection screens can be under or behind.

In the latter case it is required that the speaker must be separated by at least 10 cm from the screen.
Side Speaker:These must be on both sides of the screen, separated so that the angle with respect to the point of listening is 60 degrees.

In terms of height, it is recommended that they are among the lower level of the screen and their middle.

Surrounding Speaker: Depending on the number of speakers that sound equipment will be handled by two if the system is 5.1, Three and Four if 6.1 if 7.1.

The ideal placement is 5.1 system, which will be the most common. In this case the two speakers should ideally be behind the person at an angle of 120 degrees between them, that is 30 degrees backward.

In the case of many family room there is no space behind the place where people will sit so that the speakers may not be back.

In these cases, one option is to put speakers in the ceiling either run down, or in the top of the wall directed downwards as possible on both sides of the room.

In case of 3 speakers (6.1) should be placed 2 to the sides to the center of these, and the third in the rear to the center.

In case of 4 speakers (7.1) should be placed 2 to the sides to the center of these, and the other two in the rear to the center of each side.

The Speaker of the subwoofer:

In most cases these speakers are recommended in a corner of the room, on the floor and with something of separation of the walls.

Experts recommend installing CEDIA exhibitors in more than a subwoofer, preferred in pairs, so symmetrical. This in terms of a common room is an exaggeration from our point of view, what we suggest is that if you purchased a computer where the sound Subwoofer is active, this is the speaker that is amplified by itself, which leads to a very low power on top.

The interface or remote controls

For a user of a home theater is important that the managing of the equipments should be as easy as possible.

Consider a solution that would integrate the management of all computers in a single remote control or interface. There are large number of devices are on the market for this, since universal remote controls, automation systems to sort Creston or AMX.

Expert’s recommendation is that it can control 100% of their machines because there are a number of universal remote controls that control the single most important functions, but leave some to handle.

It is also recommend having a mix of fixed and Display buttons, so it does not have so many keys on the control and no one is lost to find a key.    

We can summarize 4 types of interfaces, or remote controls:

Universal preprogrammed

These bring the factory settings programming of remote controls for many brands, and is defined by a number code for the control of certain computer equipment.
You do not need to control 100% of the functions of a computer.

Universal with learning function

The other, besides bringing factory preprogrammed codes, they allow the learning function, add a control that does not appear to add or pre-programming of keys that do not control.

In this type of control and they can incorporate the control of other electrical equipment such as screens, lights, projectors.

Universal with programming capacity

Some controls allow us to establish programming to certain keys or actions, which can automate the operation, as the move from receiver to satellite TV DVD player, changing the audio source, the entrance to the projector and deploy the buttons on DVD the display.

These controls can be configured messages that appear on the buttons that appear on your display.

Such type of control and they can incorporate the control of other electrical equipment such as screens, lights, projectors.

Automatic Control:

These controls are more sophisticated and are directed to the Houses of intelligent automation, enabling the control of any equipment that is able to be controlled either by an infrared remote control, such as those that can be controlled via a communications port.

This type of equipment to be more sophisticated, requiring expertise to be able to exploit all its benefits.

The cost of this equipment is very high.

Expert’s recommendation is the new controls Harmony 880 and 890, which have a very practical design and a high-capacity configuration. The model 890 works by both infrared and RF, giving control capabilities through computers by Infrared technology.

Both handle a concept of activities and a display with which we can handle 8 buttons use variable. The way it is configured with the software via the Internet, download configuration and control via USB port.
