What are the roles of different channels in home theater? Compared to 2-channel stereo, how many channels can be called surround sound? The answer is 4 channels. The earliest surround sound track is 4-channel. Left front FL, right front RL, left surround SL, and right surround SR are enough to surround the audience with the sound field. The center channel C is not necessary, but if the room is larger, the center channel can ensure that the vocal dialogue is clearer.

Many fans believe that the center is very important, but if the threshold is lowered, the center will be cut off It is also the most harmless, because the center channel does not have a lot of positioning information, and the downmix to the front speakers has little effect. At this time, it is 4.0 or 4.1 channels, and the first number represents the number of main channels.
Left-front FL, right-front RL, left-surround SL, right-surround SR, center channel C plus LEF low-frequency channel form the most common 5.1 surround sound system. Of course, as the echo wall, it is not difficult to include the center channel, but there are still many low-cost echo walls that cut off the center, and you need to pay attention when buying.
The 7.1 channel is the addition of the left and right channels. At this time, they are called left and right surround, and the original left and right surround is turned into back surround. As a living room party, there is a high probability that there is no place for the speakers on both sides Not considered for now. In addition, if the sky channel is added, 9.1 channel decoding and amplification capacity is required, and the upper split amplifier + speaker is more guarantee for the effect.
