In the design of home theater, except for the selection of equipment, I believe that how to connect the home theater audio cable is also deeply bothering those who want to build a home theater. Here, I will share three home theater audio cable connection schemes for you. At present, the home theater audio cable connection includes wireless connection, echo wall connection and passive traditional connection. According to the actual needs, we can select the audio cable connection scheme that is really suitable for home.
First scheme: home theater audio cable wireless connection
There are many modes of wireless connection, but as the name implies, it is wireless audio transmission technology. Commonly used, such as the Bluetooth transmission, WiFi transmission, awlt transmission and so on, this wireless scheme is applicable to the scheme of playing the source together with the projector. This scheme is applicable to the home that has been decorated, so it is considered to only use the power line, not from the long HDMI of the TV table to the projection, projector hoisting or wall hanging, because the dialogue of the sound must be sent out from the picture direction, then the audio output from the broadcast source to the sound needs this wireless scheme. The box with Bluetooth is required, or the projector and audio can receive Bluetooth.
The second scheme: home theater audio cable active echo wall
1. If the HDMI line is laid between the TV table and the projection, the echo wall scheme shall be used. We shall divide it according to the number of interfaces and audio behind the long bar, and the figure with two HDMI interfaces is as follows:
2. With an HDMI echo wall and an HDMI arc interface, this is usually used for TV sets. TV sets have systems and loudspeakers, so the audio echo function is needed to send out the sound that should be emitted from the TV loudspeakers and the echo wall. This is the function of this HDMI arc, so how to use this interface flexibly when the projector encounters it, because the box generally has only one HDMI Out interface (other words with audio-visual separation), the overall direction is that HDMI is directly connected to the projection, and the rest of the playback source and echo wall are connected to each other. If the low-end box is not connected to my interface, then we can find a way to let it have one. Buy an HDMI audio separator and connect it to the back of the playback source, HDMI of the separator When out is connected to the projection, the upper audio port is connected to the echo wall, including the corresponding port. Coaxial first.
3. If there is no HDMI interface, it is the same with direct wiring.
4. Assuming that there is only one echo wall, wiring can be done according to the above three corresponding schemes.
5. Echo wall with subwoofer, the subwoofer generally needs to be connected to the power supply, some are wireless, some are signal lines, see the options clearly, just look for the corresponding scheme as above.
6. Echo wall of entity 5.1, which is generally integrated with decoding power amplifier and connected with active audio, must consider the following two surround sound lines when wiring. As shown in the figure, HDMI line should go from this gun to projection, around the top, and sound line from subwoofer to the rear surround position shown in the figure. The echo wall and the open line in front are all right.
The third scheme: home theater audio cable passive 5.1 scheme
The difference is that the AV power amplifier can push the speaker to make sound, so the speaker does not need power. The HDMI line and the audio line start from the TV table, go to the ceiling, around the ceiling, to the sofa background wall, and then to their respective points, which is so simple. As for 7.1, even the principle of panoramic sound is the same. Starting from all power amplifiers, it is connected to the terminal, and the front end is connected to the power amplifier.
To sum up, it is all the connection schemes of the home theater audio cable. I hope to give a little advice to the friends who are going to decorate or are building the home theater. In addition, if you have any questions, you can directly ask in the comments below, hoping to bring practical help to you.
