1, first determine the position of the speaker. If the 5. 1 system is used, it can be divided into left and right main speakers, center speakers, left and right surround speakers and subwoofer. The left and right main amplifiers are installed at one side of the TV; The center speaker is placed in the middle, which can be placed under the TV or hung on the TV; Around the left and right ends of the sofa, one on each side; The position of the subwoofer is not important, just put it in an unimportant place.
2. After determining the position of the speaker, install the speaker in place, and then connect the speaker wire. The left, middle and right speakers and surround speakers are generally wire clamps, and some are terminal boards. Distinguish between positive and negative red, positive and negative, and clamp the conductor; The signal line of the shower head for the active subwoofer is directly connected with the power amplifier.
3. After connecting the speaker terminal, you need to connect the power amplifier. The power amplifier has five power outputs, corresponding to the left, middle and right respectively, surrounding five speakers, and the active bass output corresponds to the subwoofer.
4. After the connection, it is necessary to receive the signal. Connect the playback devices such as HDTV box, DVD and hdd player to the HDMI input of the power amplifier, and the HDMI output of the power amplifier is connected to the TV.
5. This is basically done. Of course, the volume of the TV should be turned off, because there is an audio signal transmitted by HDMI, and there may be sound if the TV is not turned off. Okay, you're done. Let's watch movies at home!
Second, how to connect the speaker cable to the computer
Computer speakers are mainly divided into two types, active speakers and passive speakers. The way to distinguish two speakers is simple. The active speaker has a built-in low-power power amplifier, which can be directly plugged into the microphone interface of the computer through the speaker cable and then turned on to work normally.
Passive speakers are usually some big speakers or some old speakers without power amplifier, so you must first connect the speaker cable to the power amplifier, then connect the computer through the power amplifier cable, and finally connect the power supply to the other end of the power amplifier, so as to work normally.
1, method of connecting active speakers to computer.
The method of connecting an active speaker to a computer is very simple. You usually plug in the headphone output interface of the computer through a 3.5m audio cable, and plug in the red and white interface of the speaker on the other side. Connect the power supply and it will work. Now you can buy some computer-specific speakers with built-in power amplifier, plug and play.
2. How to connect the passive speaker cable to the computer?
Buy a stereo patch cord from 3.5 to 6.5 in the electronic market. The jack is a 3.5mm plug, and the plug wire is welded to the speaker. Simply put, the 6.5 plug is connected to a channel of the power amplifier, such as AUXDVD. 3.5 Just plug it into the signal output end of the sound card. But many people are not good at welding wires and dare not weld them themselves. First, test the polarity of the two lines of the speaker yourself. If the polarity is reversed, there will be no sound. Connect the two wires of the speaker to the positive and negative poles of the battery respectively with the No.5 battery. If you can hear the "crack" sound inside the speaker by pulling both ends of the wire, it means that the negative electrode of the battery is connected to the ground wire, otherwise there should be no sound. If it is a left speaker, it is a left channel; If the horn on the right is ringing, it is the right channel. But if it is a digital connection, only one wire is needed, one end of which is connected to the SDIF output of the sound card and the other end is connected to the SDIF input of the power amplifier, so the sound quality is better.
