VL(C)型VCD万能升级卡是一种适用任何CD、LD机升级的万能VCD升级卡,不管CD、LD的DSP型号,有无软静噪等,它是贵州中立高技术公司刚刚开发成功的新产品。该板在技术上有以下几点独创。 1.改装时,直接从CD机DSP芯片前级取信号EFM和LRCK,而一般VCD板均是从DSP芯片后级取信号BDK、DATA、KRCK。 2.由于从前级取信号,从原理上讲,一切CD、LD都可升级为VCD机,不管原机DSP有无软静噪。而到目前为止,还没有一种VCD解压板能改具有软静噪的机种。 3.由于采用仿CXD2500Q的专制大规模门阵电路集成块,其本身已包含了CD机DSP芯片的功
VL (C) -type VCD universal upgrade card is a universal CD upgrade for any CD, LD machine upgrade card, regardless of CD, LD’s DSP models, with or without soft noise, etc., it is Guizhou neutral high-tech companies have just been successfully developed New product The board is technically the following original. 1 conversion, direct access from the CD before the DSP chip signal EFM and LRCK, while the general VCD board from the DSP chip to take the signal BDK, DATA, KRCK. 2. Since the signal from the previous stage, in principle, all CD, LD can be upgraded to VCD machine, regardless of the original machine DSP without soft mute. And so far, there is not a VCD decompression board can be modified with soft noise models. 3. As the use of imitation CXD2500Q autocratic large-scale gate array integrated circuit, which itself contains the CD machine DSP chip power
