普通CD机改装成VCD/CD兼容机,由于某些CD机的先天素质差,抗干扰、纠错能力不强,使改装后的VCD效果不尽如人意,当播放质量稍差或划伤的碟片即出现频繁停顿、图像破碎、出现马赛克甚至死机等现象,令人扫兴。如增加优质万能转接板当能收到立竿见影的效果,原有劣质的影碟基本可以顺利播放。但是,万能转接板无静噪等问题又深深困扰着众多的改机者。我使用的是北京天利公司SAA7345万能转接板。此板纠错能力较强,图像停顿少,但无法绝对静噪(板上已设有静噪电路),表现在搜索、快进、暂停时,特别以装碟搜索时产生的噪音
Ordinary CD player converted into VCD / CD compatible machine, because some of CD player’s inherent quality is poor, anti-jamming, error correction ability is not strong, the modified VCD effect is not satisfactory, when the playback quality is slightly worse or scratched Discs that appear frequently pause, image crushing, mosaic and even crash phenomenon, it is disappointing. Such as the increase of universal adapter plate can receive immediate results, the original poor quality video can basically smooth playback. However, universal adapter board no noise and other issues deeply troubled by a large number of those who change. I am using Beijing Tianli SAA7345 universal adapter board. This board error correction ability, image pauses less, but can not be absolutely quiet (noise circuit has been set on the board), the performance of search, fast forward, pause, especially in the installation disk search noise
