Subtleties select a TV outlet

Modern TV is different from its predecessors of the last century, great potential and versatility. This is not just a video transmitter and a part of a multifunctional multimedia system.

It includes a plurality of broadcast domestic and foreign TV channels, opportunity Viewing photos and videos from mobile devices, access to the Internet, the use of game set-top boxes.

When a huge load on the wireless router is not always is reliable, so do not neglect the classical installation sockets for TV.

Selection of modern, in-wall module is rather extensive. We recommend to pay attention to a series of brands such as Legrand, Schneider Electric, GIRA, IEK. They have a neat appearance, made of durable materials and be easy to install.

standard module device

Setting up TV equipment has some differences from the Mounting conventional elektrotochek and it is dealt with separately, as the most important part - the cable and sockets - also differ.

There are many variants, even in the production of one manufacturer (for example, Legrand It produces popular series Valena, Celian, Etika, Galea Life), however, fundamental differences in the device does not.

The structure of the socket by the example of model ABB Busch-Jaeger:

Appearance outlet

Externally, the design of almost all types of TV sockets same: a plastic strap that is attached via two miniature screws, and TV input directly in the center

If we consider the pattern of the series Basic 55, it consists of the following components:

Antenna outlet device

Apparatus simple TV sockets: 1 - faceplate operate decorative and protective function; 2 - Caliper fixing of the socket body and between them; 3 - PCB organizes connection

The structure of the circuit board may be different - the more complex modules located therein electronic circuits. On the reverse side is the mechanism responsible for fixing the antenna cable.

Types of sockets to destination

Before installing the electrical equipment necessary to determine the choice of outlets for the TV on the wall.

To make it easier to navigate in a variety of versions, manufacturers have identified three main types:

  • simple (single);
  • communicating;
  • terminals.

Functional orientation lies in the names of categories, each of them has its own characteristics.

For example, to compile a very simple scheme, which featured a single module, acting on their own, need a simple socket. It is fundamentally different from the terminal, so ask when buying a product of this type.

Scheme socket assembly

Driving assembly simple outlet, providing a normal signal when the equipment adventure single point in the apartment. If instead install a different type, there will be interference

Simply put, if you have one TV in the room, which held a single cable, then this is your only option. If you set the apartment several televisions, but using a standard coupler, the simple outlet also come in handy.

The structure of the passage outlet is totally different. It is more like a tee having one input and two parallel outputs.

One output for connecting a video device, the second - for the cable coming on (or to the next TV, or another transient outlet). A chain of walk-through modules, always ends the installation of the terminal outlet.

There is a danger signal attenuation in the preparation of chains of a plurality of feedthrough modules. To keep plenty of power, be sure to limit 3-4 pieces.

Digital parallel connection

Provide high-quality signal can only be connected in parallel through the hub (concentrator). Additional expenditure for the purchase of an additional cable will pay off excellent video playback

Assigning a terminal outlet - close the chain bushing.

The minimum set for the living room

Previously, when you install the TV except the power supply does not require, as the antenna can be connected directly to the receiver and installed near or to obtain a more powerful signal, outputting, for roof or balcony.

Now one electrical socket small, since there are different transmission standards (digital and analog), which require their own connection.

Instead socket set 1 a block consisting of at least four pieces.

Socket strip TV

Minimal scheme for the room in which the TV set, as follows: 2 e. sockets, 1 TV socket, RJ-45 module for the Internet

We recommend installing the module block and for aesthetic reasons. If you originally had only an electrical outlet, and then there was a close private television, for it - internet entry, it will look very messy, randomly, and the place is likely to be at mind. If the planned repairs, be sure to start it with the wiring and installation of new equipment.

Two electric socket - is also at least: one for the TV, the second - for digital set-top box or other equipment, which is often connected to modern video player. TV-module provides the connection to the cable TV or antenna, derived out.

In addition, the antenna output - it is always a backup plan. Suppose, digital set-top box is out of order or somewhere carry out preventive work - thanks to the antenna cable you always have the ability to view free package standard TV channels.

Universal wiring diagram

Universal Media connection diagram of the equipment is provided with the ability to use analog TV, digital TV and access to Internet connection

Internet-input is for connecting a digital set-top box or a signal supplied provider in centralized mode. To it is supplied from the twisted pair router (not of the total panel), the dealer signals for the apartment.

Unlike the antenna cable

For high-quality connection except properly selected outlets need an antenna coaxial cable, which has a special structure. In contrast to the 2- or 3-conductor electrical wire, it has one core for transmitting a television signal, and a protective screen which acts as a barrier to surrounding electromagnetic fields.

Externally, the TV cable is a thick elastic round section wire, usually with PVC insulation black or white. For Wall-mounted color exterior insulation does not matter.

The structure of cable TV

The structure of the coaxial antenna cable: copper conductor for the transmission of a TV signal, the isolation of a dielectric, the protective metal shield sheath type plastic shell vernal

A thin insulating layer, adjacent to the central core, breaks galvanic connection with the shielding braid.

The screen is, in turn, protects against EMI and prevents radiation sensitive high-frequency signal being complementary to the same conductor. If any component fails, the video transmission is violated.

Here are a few types of cables that are suitable for installation under plaster or other finishing material:

  • 50 SAT (SAT 703);
  • RG-6 (for external use);
  • RG-11 (F1160BVM COMMSCOPE).

When purchasing be sure to check the strength of the shell, and in the packaging process and during transport, try not to bend the cable so as not to compromise the integrity of the copper core and braid shield.

Connection options schemes

There are two main circuit connection - parallel ( "star") and consistent ( "tail" or communicating). All the rest, no matter how complex and intricate they may be, are combinations of these two basic options. They resemble standard electrical circuitsBut they have a smaller voltage.

# 1: "Star" - a few independent lines

Once treated a video receiver for the rest of the apartment, is now in almost every room has a TV. To connect all devices to a single cable leading from the flap or terrestrial antenna, the signal requires a special dispensing device - a splitter or splitter.

It's kind of switching organizer, having one input for the antenna cable and multiple outputs - for connecting TVs.


It is clear the origin of "speaking" the name of the parallel associative connection options: hub is the center of a "star", and all the cables extending from it - its "rays"

Advantages parallel connection, not only in good signal quality, which is usually attenuated bushing receptacles. When installing a splitter mounted in the most convenient location (for example, in the corridor), and from it is easier to hold branches in other rooms. If one of the processes, cables will become worthless, the functionality of the rest of the network will not be harmed.

There is an improved solution "star" circuit with an amplifier, which ensures the minimization of video signal attenuation. The standard power supply is designed for 2-3 receiver, but they are usually larger, so the amplifier compensates and ultimately improves the video signal.

Driving Amplifier

Standard power (such as SAT Legrand) may be required in two cases: 1 - If the apartment is located a large number of existing TV, 2 - if the signal from the terrestrial antenna or a cable provider very weak

For parallel connection are needed or terminals, or a simple wall outlet. The terminal is better to prefer to avoid interference, if one of the TVs are not actively used. They differ from the simple presence of the wave impedance (75 ohms), which is able to balance the signal.

# 2: "Train" - communicating sequential circuit

Communicating circuit is considered a cheaper but lower quality. It is actively used in previous years, but the modern digital technologies have superseded it, because they can only work on a parallel connection.

It turns out that the "daisy chain" connection, you can use only in one case - if you have only analog TV and no change is expected in the near future.

Feed-through wiring diagram

Sequential scheme involves the mandatory use of walk-through outlets, located one behind the other, but the last in the chain have to be terminal

Communicating modules are equipped with filters, choke reflected TV signal. No filter easily identified by the characteristic ripple on the TV screen. When selecting products note the characteristics such as attenuation per pass (from 1.5 to 5 dB) and attenuation at the branch (10 to 15 dB), preference is given to the devices with the least parameters.

Note that with an increase in the number of connections of the signal quality is weakened, even if the network is provided with amp or auto regulation system, so for 4-5 or more receivers is better to use a parallel scheme.

And be sure to read the contract with the provider: in some cases, they limit the number of active points, and for the extra impose a fine.

The optimal location of the height

If you decide to place a TV on the wall, installation height outlet unit is detected automatically - it is hidden behind the TV panel. The solution differs from the standard placement options conventional power outlets. Such a method is designed for mounting telerozetok complete masking inlets, connectors, cable segments visible.

Hanging on the wall of the wires can ruin the design of the refined interior, besides their open location - risk of breakage (cut up small children, peregryzet dog, etc.).

Mounting sockets for TV

TV version of the correct position it as much as possible against the wall, all cables hidden under the lining, sockets are located in a hidden area, directly behind the screen

socket mounting height is focused on the TV hanging height, which may vary slightly. Typically, television and video are placed at eye level, sitting on a chair or couch. The optimal distance is considered to be 1.2-1.4 m (from the floor surface to the center outlet). In relation to television - slightly below its upper edge.

But there are exceptions. For example, video device kitchen often mounted slightly higher in the free space, respectively, and outlet should be set above the indicated heights.

How to install a simple TV outlet

Before mounting the socket is necessary to cable (for a simple single - a single cable leading from the distributor). His camouflage or closed method - a plaster (gypsum board, a decorative panel), or open - on the surface of a wall, in the cable channel. For the second option requires external (overhead) power outlet.

For a sample take a quality product from a French manufacturer.

Before installing a drill with a round nozzle is necessary to cut a hole and insert a plastic box (Escutcheon). Of holes should extend the cable length of about 15 cm.

cable preparation

end of the cable should be prepared: to remove part of the outer insulation so that the copper conductor appeared about half a centimeter, and a part of the shielding is bare, too, it was

Next to disassemble the housing apart.

Preparing the body

After separation of the front panel is a clamping screw, which provides stability, and unscrew it slightly to make it easier to insert the antenna cable

Insert the cable in the direction of the arrow and fix the special clamp, tightening the screw.

Quality control connection

Under the small arrow is a through hole for monitoring adherence of the copper conductor. But for greater reliability of visual inspection of small, to better test quality installation, you must use the tester

Check tester eliminates the occurrence of short circuit due to inadvertent contact with the braid conductor.

Aligning outlets

Carefully, trying not to disturb the position of the cable, insert the casing in the Escutcheon, fasten fasteners and snaps on the front panel bezel. Using a level aligned position of the block

The result of the assembly and installation - no protruding wires and connectors unprotected.

Variant multifunction unit

Outlet unit is typically one long panel, divided into several functional sectors: for connecting a coaxial cable, internet wire RJ-45 (twisted pair) or electrical cable

Installation of the flow module will be slightly different.

Features parallel and pass scheme

If you are not limited to the installation of outlets for one TV and want to use the "star" scheme, please note the following nuances:

  • First install a splitter, and only then - the socket.
  • Each output of the splitter, connect one cable, which should end with a mounting socket (simple or termination).
  • By installing a simple module, note that they are not equipped with filters.

Watch out for speed. GOST (P 52023), a possible frequency should fall within the scope of 40 to 1000 MHz, and some devices "narrow" set limits. For example, the operating range DOCSIS v.2.0 - from 47 to 862 MHz, respectively, the outlet support these limitations.


If you own a large two-storey cottage, the cabling for different purposes need to consider prior to finishing. In the scheme - an example of the connection of various technical devices with an indication of the type of cable, the numbers designate televisions

If you are not interested in digital TV and you choose a consistent connection scheme, do not forget about a quantitative restriction.

The more outlets - the weaker the signal. Of the permitted level of Russian guests in the 57-83 dB is already installed when you run out 3-4 pieces tempered limit (per outlet - about 15 dB).
