厦门“冬日之歌”鹦鹉螺胆皇诠释天籁之声

HV T^'^treporiN e w s路边新事作者专为本次活动而作的画文/陈建华Bow ers & W ilkins Nautilus ,发烧友尊称"鹦鹉螺”，虽然在音响界它神一般的存在，诞生将近三十年了，能闻其声者少之又少，业界人士都很少听到它开声，更别提一般发烧友了。

主要是它要动用八台单声道后级或者4台立体声后级，加上对环境要求比较高，一般展会上或者音响店只做静态展示。

这被全球公认的一款杰出的扬声器，上世纪九十年代初它就以当年最好的制作工艺，融合外观设计、声学设计，针对高要求的音乐发烧友，同时也是Bow ers & W ilkins *^司的"镇店之宝”，如今能在2020年底最后一个周末在厦门开声演示，不去一饱耳福，哪怎么能够说得上对音响音乐的热爱呢？这场音响盛宴由汕头歌德影音携手福建壹歌智能于2020年12月26日在厦门市湖里高新区宏益华府举办「冬曰之歌」音乐沙龙，为厦门的发烧友带来了一场有情感有温度的音响音乐盛宴，一同感受了 Air Tight、Bowers & W ilkins 、Zonotone 等设备的魅力与感动。

这场音乐沙龙由资深发烧友 "金驰”方展武老师主持，特约神秘嘉宾顾忠良老师，待会会做介绍。

几款音质出色的国产胆机

近些年来，国产电子管Hi-Fi放大器制造得到了飞速开展，且音效卓越。

著名的电子管放大器制造厂已有十多家，产品在国内外市场上销售旺盛，并有很高的声誉。

出色的放音效果以及相当高的声价比，赢得了众多的胆机用家的欢迎和媒体的好评。

本文就介绍几款音效奇佳的胆机。

1 MELODY SP-3、SP-6及十周年纪念版SP-31.1 MELODY SP-3MELODY是国内最有声誉、最具规模的胆机制造厂家之一。

10年前推出了型号为SP-3的合并式胆机功放，设计制造极有创意，银灰色的机身艺术性很强，声音表现极有魅力，很受胆机发烧友的青睐，媒体也给了很高的评价，称是历来最靓声的合并式胆机功放，因此也有很高的销售量。

输出功率每声道为38W，见图1。

图1 MELODY SP-3SP-3外型新颖，制作认真，并且用的都是些发烧级的好声元件。

此机以6L6为功率放大管，前级电压放大及推动管用12AX7、6922、12AU7。

电源变压器、输出变压器是手工绕制的重料之作。

B+高压滤波电容用的是发烧级的名牌电解电容。

音量电位器用24档电阻级进式的〔所用的电阻是HOICO牌〕，这对两声道的平衡、对称及音色的通透极为有利。

HOICO电阻是最靓声的品种，传递音乐精华的性能极强。

机内组装焊接极为严谨、工整、讲究，焊点饱满圆润。

多年来6L6是倍受欢迎的功率放大管，无论是单端输出，抑或推挽输出都有靓丽的表现。

再加上设计者高超的调校技术，将6L6的特点、魅力发挥得淋漓尽致。

SP-3的音色甜润，声音饱满，音乐感丰富，声音的平衡度好，尤其中音优美，低音雄浑有弹力。

有评论称SP-3具有古董名机Mclntosh MC-240功率放大器的声音特色。

SP-3是名气最大、销量最多的High-End电子管功放机。

1.2 MELODY SP-6正当SP-3受到很高的评价时，厂家又推出型号为SP-6的电子管合并机。

它的外形、构造和SP-3型如出一辙，完全一样。

前级电压放大、推动部份用的放大管也与SP-3一样(12AX7、6922、12AU7各两只)，但功率放大管改用了曙光制造的五极功放管EL34(同类型号是6CA7)，作AB类功率放大，输出功率每声道为40W。

Laney L20T-112 212用户手册说明书

简介在英国非常自豪的设计，工程和制造狮心王（Lionheart）系列带来精品的单端或并联单端的甲类电子管音调提供给独具慧眼的演奏家，正是他们一直在寻找的一种独特的灵敏的具有英国特色电子管音调黑魔法:在这个吉他手对前置放大器失真产生了一种不健康的迷恋的时代，传说中的电子管功率放大器被使劲推的声音几乎成为了历史。

直到现在!20W并联甲类单端输出级安装在L20T-112 和L20T-212渗出经典，温暖的电子管色调。

你驱动得越重，听起来就越好。

加上有足够的增益为现代的音调，它也有凶猛、侵略性的一面，使它适合任何风格的玩家. 完美的用于工作室和实践使用.每一款狮心王 Lionheart产品都是由经验丰富的吉他手进行广泛的演奏测试，然后才发货给我们的客户。

只有当设备完成到我们完全满意时，它才被分配到自己的独特的建造编号，然后手工敲击在后面安装的铭牌上。

你的L20T应该给你多年的无故障放大，然而，请花时间阅读本手册和熟悉自己的控制，因为它将允许你得到最好的放大器。

我们希望您喜欢使用您的L20T，就像我们喜欢设计和制作它一样。

来自全体LANEY成员的最美好的祝福高输入:“HI”代表高增益。

这种输入是为低输出电平吉他的连接而设计的，使它非常适合单线圈和低增益双线圈型拾音器。

在这个输入中使用高增益拾取可能会使驱动前置放大器太硬，造成“模糊”的声音。

只能使用优质的吉他电缆.低输入:“LO”代表低增益。

这种输入从高输入衰减了大约50%，是为高输出电平吉他设计的。

它对于从高增益双线圈型拾音器获得“紧密”而不是“糊状”的输出非常有用。

也使用这个输入为最干净的全范围的声音与扩展低端响应。

只能使用优质的吉他电缆.清音音量：设置清音通道的响度。

试着把它调高一点，以驱动功率电子管更重以获得真正的复古声音和感觉只有一个高品质的电子管放大器可以提供. 现在用你的吉他音量来控制失真的程度。

(前进一点为失真，后退一点为清音)明亮：当你的吉他在清音通道时为高音频率增加亮度和活力.当你的吉他在驱动通道时增加边缘和挑选重点. 该开关在清音音量/驱动器控制较低设置时影响更大。
