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 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 played back as the front left and front 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:
The PLC splitter is used to separate or combine optical signals. A PLC is a micro-optical component based on planar lightwave circuit technology and provides a low-cost light distribution solution with the small form factor and high reliability.
Rackmount Splitter is manufactured using silica glass waveguide circuits that are aligned with a v-groove fiber array chip that uses ribbon fiber. Once everything is aligned and bonded, it is then packaged inside a miniature housing. PLC splitter has high-quality performance, such as low insertion loss, low PDL, high return loss, etc.
High quality; low failure rate.
