[Home Theater Network HDAV.com.cn] In the design aesthetics, we must pay attention to both the practical and the overall aesthetics. Nowadays, the acoustic treatment of the indoor environment is very perfect, but the aesthetic treatment of the room is neglected. In the traditional home theater, the cotton is used to attract cotton or the suction board is used as the decorative surface. Such professional acoustic materials are often incompatible with the “warm and comfortable” living environment, and how to integrate the acoustic materials. In design, it becomes extremely important. If we want to consider the design, we must first have a general understanding of the acoustic processing and equipment installation of the home theater. The room should be as regular as possible, that is, the rectangular shape. Today, we first talk about how the home theater design is divided on the equipment, and in which environment these devices are used, in order to facilitate users to choose the right audio equipment for their own room environment.

With the improvement of the residential environment and the rapid improvement of the quality of life, today's audio is no longer a luxury product. There are also a variety of home audio products on the market. For home theater, it includes design, construction and equipment selection. And installation and many other aspects. Therefore, a "fit for" your own home theater equipment has become very important.

Room requirements and channel reservation

As far as design is concerned, a good home theater environment has certain requirements in the aspect ratio of the room. Generally speaking, we use the narrow side of the room as the screen position, while the long side is designed as a sound absorption or reflection. In terms of proportion, it should be a rectangle. If the user chooses the wall-mounted speaker, then the construction requirements must pay special attention to the way of wiring. It is possible to go to the ground, along the wall line or ceiling wiring, in addition to the shortest and provincial wiring principle. Preparations should be made for reservations. Because the dark lines in the design are basically one-time decoration, it will be very cumbersome to add later, and even destroy the existing decoration. Therefore, when wiring, we must consider the need to add more in the future. Channel.

Home theater cabinet classification

In the use of speaker in the home theater, we can be roughly divided into three categories: wall-mounted speakers, stand-alone speakers and wall-mounted speakers.

First, let's take a look at the main features and installation methods of various speakers.

(1), wall speaker

Wall-mounted speaker: In order to match the slim shape of the flat-panel TV, the shape of a typical wall-mounted speaker or flat-panel speaker usually looks slim, and most of the appearance is balanced with the screen, and the style is fashionable. This is different from the satellite speakers that we usually touch. Satellite speakers are also among the wall-mounted speakers, slightly larger and thicker. No matter what kind of wall-mounted speaker is facing a problem at present, it is slightly smaller, the unit used is small, it is difficult to have very good low-frequency performance without using a subwoofer, so the wall-mounted speaker is recommended. Use with a subwoofer. In terms of design, the wall-mounted speaker has various shapes, is also beautiful and fashionable, covers a small area, is easy to install, and is also favored by users of some small rooms. If your room is around 15 square meters and you don't adopt a concealed design, it is recommended to use such speakers.

(two), independent speaker

Stand-alone speakers: Stand-alone speakers can be said to be the best way to achieve sound effects. For enthusiasts, the outstanding effects of stand-alone speakers are still the "standard" in all speakers, and the stand-alone speakers also allow users to own Greater freedom to arrange your own audition space, may be very good in the fine-tuning and positioning of the sound. But at the same time, the huge size of the stand-alone speakers will take up more space and interfere with our view, which is also a disadvantage of stand-alone speakers. In terms of sound quality, the stand-alone speaker must also be connected to the subwoofer, because we know that the subwoofer below 40Hz needs to use the subwoofer to perform. This is difficult for any main channel speaker.

(three), wall-mounted speaker

In-wall speakers: In-wall speakers have been around for several years. The sound quality of the excellent in-wall speakers is now close to that of stand-alone speakers. The advantages of the wall-mounted speaker are actually obvious, saving space and “wasting” space. How to say it? “Saving” is visually saving. That is to say, at first glance, the whole room looks clean and there is no speaker blocking. Sight. "Waste" requires more space to install it, because the wall-mounted speaker needs to use the wall as a "box" or install its box, which means that the thickness of the wall is "thick" "That means that the space in the audio-visual room will be smaller, but it will be visually "spacious". The biggest feature of this kind of speaker is to save space, and good concealment will not affect the design style of the whole room. In the home theater system, the hidden performance of the wall-mounted speakers makes the audience's attention more focused on the screen. Therefore, the wall-mounted speakers have been warmly welcomed in developed countries such as Europe and the United States. In the subwoofer setting, the in-wall speaker can be selected as an in-wall subwoofer or a traditional subwoofer, and the effect is satisfactory.

How to choose the speaker that suits your room

In the choice, we must first confirm the size of the room and the direction in which the speakers are placed. These two points are very important, followed by the size of the room, the size of the caliber, and the selected speaker. What kind of visual effect can be achieved without affecting your own viewing experience. If the room is too small, there is not much need to consider the use of large stand-alone speakers or wall-mounted speakers, because the high-quality wall-mounted speakers with a high-quality subwoofer can make a good sound in a small room. The sense of density and the sense of envelopment are equally shocking. In the case of a large room, if the conditions permit, you can consider the use of wall-mounted speakers, because it is more concentrated in the visual focus while ensuring the sound quality, it is also a good choice for viewing. Finally, the use of stand-alone speakers can be set in larger rooms, or like fans and music, because most people still like the sound and visual mix, that is, the concept of "listen to see and see." In short, understand the characteristics and installation methods of various types of speakers, it is not difficult to match the speakers suitable for your environment.

Ethernet power supply system is referred to as POE power supply, which consists of Ethernet power supply equipment and Ethernet power equipment. It can transmit data and provide DC power supply to client equipment only through one Ethernet cable, without the need for additional wiring.Gigabit POE Switches are divided into managed and non-managed POE switches ,non-standard POE switches which do not meet the IEEE802.3af/at. and also it has indoor series and outdoor series  with 10/100/1000M input and output port.

Features:

1. Can recognize the impedance of the signal. When an input voltage is applied to the device, it must be roughly identified within the defined voltage range. When an ethernet power device pleads for power supply, it first sends out the voltage signal of 2.5V~10V to Ethernet. After detecting the voltage signal, the power facility puts a 23750 ohmic resistor on the power supply circuit, and the current changes with the input voltage. By detecting the current, it is confirmed that there is an effective Ethernet power supply at the Ethernet cable terminal. If the arranged resistance value is in the area of 26250 / 45000 ohms, it is considered that the ethernet equipment is effective but does not need to supply power. Resistive values of other sizes mean that the detected ethernet equipment is useful. 

2. Type. Electricity is equipped with a type of gap, each type corresponding to not a certain current. Analogy, the "0" class of electricity is equipped with a current of 0.5 Ma 4 Ma. When an effective signal is detected by a power supply, it is classified. The specific method is to lift the voltage to 15.5V or 20.5V on the Internet link, so that the Ethernet power equipment loses a static current, and then completes the classification of the power facilities according to the current scale. 

3. Open coherent connection. There are two kinds of switches connected to Ethernet power supply (Poe power supply), one is bipolar crystal switch, which has high utility and low capital, and the other is MOSFET switch, which has extremely high power performance and can be close to 100th.

Application:

Suitable for different Ethernet devices such as: IP phone, network security camera, PDA, mobile phone charger, card reader, etc.
