Have you found that TV sets are getting thinner and larger, and their resolution is getting higher and higher, but the sound quality of TV sets has not improved. I always feel that the volume is not large, the sound quality is not good, and the bass is not obvious. This is also the reason why TV sets are thin. The machine body is so thin, and there is no place to place speakers.

So now many people will consider purchasing another set of professional audio equipment, which can solve the problems of poor sound quality and low frequency. But how can professional audio equipment be connected to TV? Many people don't know how to connect professional audio and TV. Now take 5.1 audio system as an example to teach you a set of practical lessons.

Firstly, determine the position of speakers according to the listening environment and sofa layout. Professional audio equipment 5.1 system includes left and right main loudspeakers, center speakers, left and right surround speakers, and subwoofers. The left and right main amplifiers are installed on both sides of the TV; The middle speaker is placed in the middle, usually under the TV; Around the left and right sides of the room; There is no special requirement for the position of the subwoofer. If you want a more powerful effect, it is usually placed in the front.

After the location of the speaker is determined, it is necessary to install the hanger and fix it, adjust the angle, and then connect the speaker wire. The left, middle and right speakers and surround speakers are generally clamped, and some are terminal blocks. Distinguish between positive and negative red, positive and negative black, and clamp the wire tightly; The active subwoofer is directly connected to the power amplifier with the signal line of lotus head.

After the speaker terminal wire is connected, it is necessary to connect it to the power amplifier. There are five channels of power output on the power amplifier, respectively corresponding to the left, middle and right, surrounding five speakers. The active bass output corresponds to the subwoofer. After connecting, it is time to connect the signal. Connect the high-definition TV box, DVD, hard disk player and other playback devices to the HDMI input of the power amplifier, and connect the HDMI output of the power amplifier to the TV.

But you must purchase an active speaker. Connect the audio signal cable of the active speaker to the AV output on the back of the TV, and the audio output is red and white. If you purchase a 3.5 active speaker signal cable plug, you must purchase a pair of audio cables or conversion plugs with a red and white lotus plug at one end.
