某些机种VCD,尤其是由CD机改装为VCD机,在CD-DA与解压板交连后,往往在快进快退状态下,左、右声道会输出令人讨厌的噪声。为抑制这类噪声,只需对原控制矩阵电路稍加改进,即可实现快进、快退 Some models VCD, especially from the CD machine converted to VCD machines, CD-DA and decompression board cross-linked, often in fast forward rewind state, the left and right channels will produce annoying noise. To suppress such noise, only a slight improvement on the original control matrix circuit, you can achieve fast forward, rewind
