许多乐迷在选购音源CD机或音频解码器时都难免目迷五色，无从下手，那么有没有一盘能不 借助于仪器就能试出器材性能的试金石呢？回答是肯定的，由喇叭花唱片推出的《My Disc》又名（我的碟）就是这样应该人手一张的猛碟，它不仅用于挑选音源，还用于整个音 响系统的甄别和最后的摆位调校以及煲机和练耳，被誉为发烧友人人必备的利器. “喇叭花”公司简介: 在20世纪70年代至80年代初，有一家美国小型发烧录音公司在发烧界真称得上是无人不晓， 这家公司首创一种叫做“直刻LP"(direct-cut LP)的技术，即录音时不经过母带做中介，而 是直接将来自麦克风的信号输送到刻片机上，这样生产出来的LP拥有最自然、最真实的音质 效果，而且由于产量的稀少，这些直刻LP成为发烧友梦寐以求的发烧珍藏品。现今 存世的直刻LP，在拍卖市场上均已被炒到天价，而这数十个“直刻”录音，几乎都被TAS天 碟榜列入榜中，代表了人类录音技术达到的顶峰。以“直刻LP”技术名震天下的这家录音公 司，就是谢菲尔德实验室(Sheffield Lab)，俗称“喇叭花”公司。 如何使用《我碟—Sheffield／A2TB测试碟》 ●田卫平译 在美国Sheffieldlab公司出品的《我的碟》(My Disc》，the Sheffield／A2TB Test Disc) 的封面上，制作人写着：“一张评估音响器材、听音环境及听音能力的测试碟”。的确，这 是一张音响发烧友不可缺少的用于进行全面音响测试的工具碟。这张光碟包括音乐测试和技 术测试。音乐测试部分选择了几种音乐式样，这样几乎每个人都可找到一种音乐形式来适合 个人的口味。技术测试部分录制了各种测试方法及测试信号，这样会排除很多变量对音响系 统全面表现所带来的影响。这张测试软件包括了一些特殊信道，使你在使用或者不使用专业 测试设备的情况下都能分析音响系统的表现．个别信道只能在使用专业测试设备时使用，这 几个信道用一个手形符号标出。即使你有专业测试设备，但你可能并不总是随身携带着，例 如当你在一位朋友家评估一套音响系统的时候，或在试音室里试听一套音响的时候。无论你 是一个音响发烧友还是一位音响专家，《我的光碟》都将是你最有用的软件。为了说明这张 碟的一些效果，制作人不得不在一些音乐信道中演示特殊方法。前六个信道是从原版中直接 数码输出。这些信号的用意是既有参考性又有一般性的听音评估。 CD曲目： 01 The Power Of Seven / Stranger In My Bed 03:49 02 Thelma Houston / Dish Rag 03:34 03 Los Angeles Philharmonic / Dance Of The Knights -
