爱华430组合音响,外观美,音质好具有卡拉OK、混响器,所以笔者决定为其增加VCD播放功能,并利用原有的功放、混响、音箱,建立简单的“家庭影院”,以为其它组合音响改为“家庭影院”提供参考。组建的关键是首先将原CD机,改为VCD机,其改装步骤如下:打开外盖,发现该机使用的DSP芯片为CXD2518Q,根据资料,该芯片存在“软静噪”即使改变其工作模式解除静噪,改装后的VCD效果也不理想,所以笔者从广东大伟经济公司购买一块V-9万能前置板和一块普通VCD解压板KH-VCD,以及一个电子合成板和射频调制盒。
Aihua 430 combination of sound, the appearance of the United States, with good quality Kara OK, reverb, so I decided to increase its VCD player, and use of the original amplifier, reverb, speakers, the establishment of a simple “home theater” that other Combination of audio to “home theater” to provide a reference.
