【重庆道声】大众帕萨特音响改装奢华盛宴，DTS5.1声道影音环绕系统品鉴贴<br>
<br>
<br>
之前有朋友问过我：“有5个声道+1个低音就是5.1声道了吗，DTS环绕就是这样的做法么？”对于这样的问题有的时候真的不知道怎么去回答，本质上来说，肯定不是的，但是从最基础来说回答是也并不完全错误。借这个贴和大家具体说下到底怎样才算是DTS5.1声道。<br>
<br>
DTS公司推出了多种声场技术，其中DTS Digital Surround是最广为流传的一种，属于5.1声道系统，人们通常说的DTS技术，或者DTS环绕，一般就是指DTS<br>
Digital Surround。DTS采用CAC（Coherent Acoustics Coding，相干声学编码）方式工作，和Dolby Digital一样也属于利用心理声学原理来对声轨进行编码的有损的数字压缩技术。在电影院中，DTS的声迹录音采取了特殊的声画分离的数字立体声，数字声迹录在光盘上，由专用的光盘驱动器读取，另外在拷贝的模拟声迹与画幅之间录有时间同步码，用来控制光驱还音与画面的同步。<br>
<br>
DTS分左、中、右、左环绕、右环绕5个声道，加上低音声道组成5.1声道，这一点和杜比数字相同。但DTS在DVD中标准的数据流量为1536kbps，而Dolby Digital的数据流量是384Kbps～448Kbps，最高可提升到640Kbps，显然相比之下DTS具体更高的数据流量，也就具有更低的数字压缩比。数据压缩比越低，占用的记录空间越大，但其重放音质就有可能越好，加之DTS采取高比特、高取样率等措施，使之对原音重现的追求上就更进了一步，因此DTS被很多人认为比Dolby Digital具体更好的效果。<br>
<br>
文字叙说可能会会相对比较难理解，那么就随我们一起继续用图片来理解。首先看看我们这次改装的整体配置风格：<br>

这次的改装案例所有的配置都特别考究从音源主机W502（解码）光纤输入阿尔派H800音频处理器，再到“拥有灵魂的喇叭”C62C，以及特意用了两台喜力士A类功放分别推动这套喇叭的高音和中低音（主动分音）。中置先锋，低音美国钻石竞赛级HP12，无一不是经过精挑细选过的发烧音响器材，所有的组合打造成这一次奢华盛宴！<br>

精彩部分：<br>
在这个级别里，PASSAT的发展就像一个函数曲线，不断的在趋向一个高水平的极点，以至于我们对它几乎已经到了无可挑剔的地步。不过在各项性能都趋于完善的同时，也让大家对这种标准产生了一点麻木，给点惊喜不行吗？行，肯定行！各性能的优越在于驾驶，而对于车载音响的发烧友来说，原车音响是不能出台面的，要改就大改。<br>

大家都知道这样的大改配置一朝一夕是不可能完成的，我们这台车从接单到施工结束一共用了四天的时间来完成。在这四天的时间里我们所有的师傅都用最专业最严谨的态度，把这次改装绘画成一部最精美的作品。图片中的车子外观可以看到，已经全部用专用的车身保护膜整体保护起来。<br>
