[Home Theater Network HDAV.com.cn] Recently, no matter whether it is QQ, WeChat or forum, people have asked me what is the difference between 7.1.4 and 7.1.2. I was prepared to open a new post, forget it, just in this post, solve it. I can guarantee that this will be 100% of your yearning for 7.1.4. If you can only install it to 7.1.2, I suggest that you do not look down, so that you can't pack the box and blame me.
First of all, you have to have a Blu-ray disc called Teenage Mutant Ninja Turtles. Then, I started to talk about it:
This movie, I watched in Taiwan in August, not a panoramic cinema, but at that time I felt that the layers were distinct and the low-frequency impact was very good. At the opening, everyone could listen to the vocals, the background music, the separation of sound effects, Knock down your ears first.
Then, the turtles first appeared, this sound effect, I think can be calculated full score, low frequency dynamic, physical, thunderstorm atmosphere, I like it very much. I will use this paragraph to talk about 7.1.4? No, I will not choose such a noisy scene, so noisy, not suitable for distinguishing details. I will choose a slowly moving lens to tell everyone about the changes in the voice.
Ok, it’s a good show.
This episode is, the heroine, finds the turtles, and then starts to track the footage from the downstairs. I divided it into, 7.1.4, 7.1.2. 7.1 to explain, you can compare with your own system. I deliberately open the Blu-ray machine information, everyone pay attention to the time of each corner, to facilitate comparison.
Fragment: 1
Start here (and go further)
The heroine found the turtles and turtles talking on the roof and the sound was louder. The heroine is ready to start climbing
7.1.4: There is no dialogue between the two channels in front of the sky channel. The dialogue is completely concentrated on the rear-mounted channel of 7.1.4!!! Sometimes there is no dialogue, the position of the heroine changes, and the surrounding objects have an influence on the sound.
7.1.2: The dialogue is concentrated in the middle of the sky channel, and the performance here is not too different from 7.1.4.
7.1: For this episode, 7.1 I think it is abolished. . . Because there is no sky channel, the dialogue is pulled into the side ring and the back ring, the sound that should have been in the sky, separated into four surrounds!
Fragment: 2
The heroine started to climb the stairs, we continue to pay attention to the dialogue
7.1.4: You will find that because the heroine is on the left side of the screen, the painting is mainly sent by the rear right channel of the sky channel, that is to say, the dialogue is sent from the top of the head to the right, and the sound and the picture are perfectly unified.
7.1.2: The difference is not the same as that of 7.1.4, which is perfect.
7.1: I can only say huh, because the dialogue is still in the four back rings.
In the first two scenes, the dialogue is concentrated at this top position, drawing a picture, everyone understands
Fragment: 3
As soon as the top is over, the turtles are speaking louder and louder. At this time, the difference between 7.1.4 and 7.1.2 is different.
7.1.4: The dialogue appears in the sky in the first half of the room. You look up at the curtain and the white knot is at the front 45 degree sky position.
7.1.2: The dialogue has been basically in the middle of this time. . . The height of this sound is very inconspicuous.
7.1: Performance see 7.1.2
The position where the dialogue appears is here on the top of the sky.
Fragment: 4
Actress probe
7.1.4: The dialogue descends from the top of the head and appears directly in front.
7.1.2: Starting from the previous shot, the dialogue is always in front and there is no change.
7.1: Ibid.
In the HAA course, the teacher often visualizes and visualizes what I listen to, let us see it. Ok, today I am not lazy, I draw a picture. Everyone has seen the dialogue in the 1.2.3.4 scene above. The arrow takes the direction of the dialogue movement. The above 1.2.3.4 corresponds to the position of the dialogue that I mentioned earlier.
Let's take a look at the picture below, which shows the direction of the dialogue in the room.
The first is 7.1
Then is 7.1.2
Finally, 7.1.4
I will add a knife to see the motion picture of the dialogue channel from the top.
7.1
7.1.2
