Surround sound circuit
The surround sound system can reproduce rich on-site information and form a sense of surrounding the audience, so that the listener feels like being on the scene and obtains a more realistic listening effect. The surround sound effect is obtained through a special surround processing circuit. There are currently three popular surround sound processing methods: one is the 4-4-4 split system. When recording music programs, the system records the sound information of the front left, front right, rear left, and rear right on four tracks such as audio tapes. When reproducing, the original channel signals are reproduced. . Such a system is complicated and expensive, and it is difficult to promote it. The second one is the encoding method 4-2-4 system, which is mostly used in the Dolby surround sound film return system in stereo cinemas. It has been gradually used in home audio equipment, called Dolby logic surround sound, but the price is not low. , Working-class enthusiasts are still more difficult to access. The third type is called 2-2-4 type quasi surround sound system, and its processing method is: the left and right channel signals of the two-channel stereo are subjected to composite mute processing and then reproduced as front left and right signals. At the same time, another group of signals is separated and processed by the surround sound processing system to generate analog surround signals, which are sent to the surround sound box for playback. Surround sound is produced in this way, which is more common in low-end and mid-range combination sounds. Circuit principle: Component selection: Diameter 20mm DMX 3D Tube we have different length 0.5m, 1m, 1.5m and 2m , led on double sides with 360degree beam angle for disco,bar,nightclub decoration. the DMX 3D Tube work with DMX Artnet Controller and Madrix software, the LED 3D tube can achieve 3D effects, like 3d illusion lamp, with Madrix software, the 3D LED Tube can music makes lights.
