Production of high-quality combined amplifier
With the development of the domestic economy, people have turned their attention from the combination of sound to the formation of home theaters. The core of the home theater is the surround sound system. China has entered the AC-3 era, but it must match the speaker design, otherwise it will be difficult to show its superiority. The domestic Dolby directional logic surround decoder is the first to launch YAMAHA YSS-215, etc. Decoding chip, but its price remains high. M69032 is cheap, but the resolution is average. All in all, with Dolby surround sound, you must invest a lot of signal cables from the hardware, it will make your listening room inferior, if you have not the ability to purchase the above equipment, you may wish to try the SRS system to make two The speaker reproduces the three-dimensional surround sound effect. The SRS system is based on the principle of bionics, according to the structure of the human ear listening system to produce the listening rhythm, after proper processing, two speakers are used to achieve a three-dimensional surround sound field. The high-quality power amplifier introduced in this article is based on SEAKO / NPC's SRS5250S IC chip, coupled with 250WX2 dual ultra-linear, pure DC power amplifier without negative feedback to form a low-cost, high-quality home theater.
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.
Advantages
Suitable for multiple operating wavelengths (1260nm – 1650nm); unstinted.
Equal splitter ratios for all branches.
Compact configuration; smaller size; small occupation space.
Good stability across all ratios.
High quality; low failure rate.
