AC-3 5.1声道杜比数码“家庭影院”,是目前最通用和效果最好的家用AV设备。用AC-3解码器和5.1声道所组成的功率放大器,大多数是进口名牌产品,国产品牌尚不多见,且价格昂贵。虽然AC-3解码器自制难度极大,也无成品板可提供,但我们完全可以采用那些自带AC-3解码器(有的还带DTS双重解码功能)的DVD机,自己组装一台5.1声道功率放大器。
AC-3 Dolby Digital 5.1 “Home Theater” is by far the most versatile and effective home AV device. With AC-3 decoder and 5.1-channel power amplifier composed of most imported brand-name products, domestic brands are still rare, and expensive. Although the AC-3 decoder is extremely difficult to build, there is no product board available, but we can fully use those DVD players that come with the AC-3 decoder (and some also have the DTS dual decoding function) to assemble a 5.1 Channel Power Amplifier.
