PMC BB5i监听音箱
新入书架箱PMCTB2i，简单听感汇报
新入书架箱PMCTB2i，简单听感汇报偶HIFI音乐和影院2/8开，这两年净折腾影院设备了，目前影院效果自己还算满意！但用我签名这套系统听音乐，总觉得差强人意，听CD音乐开始还好，越听越不耐听，声音硬且脆有毛刺感，人声口型也散。
于是打算置套入门的设备专门听音乐，到器材店听了几次，最后决定先入一对书架箱PMC TB2i，前天到器材店又去听，觉得满意，一咬牙就交钱提货了。
PMC TB2i箱的技术指标就不介绍了，网搜一大堆。
直接说说我的听感吧！和我的杰士RF83箱及用了10年的德国密力HIFI箱MAGNAT VECTOR 77对比一下。
对比用的其它器材为碟机剑桥550C，前级糠MC-12HD, 后级ATI1807(用其2声道)。
播放曲目：蔡琴的《恰似你的温柔》《遇见》《被遗忘的时光》童丽的《烟花三月》《葬花吟》电影原声音乐《黄飞鸿》里面第一首（记不清曲名了）朱哲琴《阿姐鼓》之《卓玛的卓玛》对比感觉：蔡琴那醇厚的嗓音透着沉静、知性和成熟女人迷人的万般风情，听着她“糯糯”的哦吟，那些逝去的时光和在心中沉睡的记忆，便会慢慢苏醒。
TB2i表现的非常突出，非常耐听，属暖色调，而RF83的人声表现有些硬；蔡琴的《遇见》,除了蔡琴饱满有感情的歌声,晚上郊外天籁的背景声...青蛙叫,蟋蟀声，触手可及,把灯灭掉,真的以为自己就在现场，TB2i 表现的很自然、真实，RF83细节表现也不差，但对比之下，就有些不自然，密力77的表现稍好些。
《恰似你的温柔》里面琴弦的泛音RF83的有些尖、略刺耳，TB2i 好多了，密力77的表现也不尽人意。
童丽甜美、清润的嗓音，再加上出色的江南小调风格，容易让人有耳目一新的感觉，自然融合“气声”、“真声”、“戏曲唱腔”的发声方法是童丽最大的特色，TB2i演绎的很甜美，对比之下RF83的人声厚度、磁性虽有，但中高音音硬、脆的毛病又出来了。
密力77表现还好。
《卓玛的卓玛》是该碟中低频最丰富而最具弹性的一曲。

读友信箱|读友“初哥”的一大堆问题Q本人是“初哥”，对器材知识一窍不通，有很多问题要向各位编辑请教。
以下是近年陆续所购器材：音箱：燕飞利仕SM85、B&W 601S2、B&W S805 AV功放：ARTISA AV-R8100（日产冠傲）两套纯功放：1、安桥P301前级，M501后级；2、音乐传真A3.2 CR前级，A3.2 CR后级CD 机：JVC XL-GM800PTN（七碟连播）DVD机：先科AEP-826PB（支持HDCD）脚架：1、君子黑武士；2、杂牌木脚架电源滤波器：G&W 2D和3D 以上器材有部分是我弟所购，他到外地工作后全部归我。
由于环境等因素所限，对于现场音乐会和高档器材组合所发出的美妙声音无法亲身体验，再加上工作较忙，无充裕时间去折腾这些东西，故对现有器材组合的素质及声音特征心中无数，只好请编辑解惑。
1、音乐传真A3.2 CR前后级（130W）和安桥前后级（150W）各能推出S805几成效果？如不适合，应配什么箱子比较好？（打算以后再配一对箱子，世霸与丹拿孰好？）2、现有JVC碟机档次太低，请介绍一台性价比较高的机器（SACD、CD均可）。
本人听过音乐传真A3.2碟机，感觉该机通电后空机状态下开大音量后有一定噪声（功放也是如此！技术指标上信噪比是很高的，不知怎么回事？）“英国之宝”合适否？推荐的器材请告知沪、杭、宁地区代理商的联系电话，或国内总代理的电话。
3、请推荐2套中价位线材：电源线、信号线、音箱线各2款。
本人不懂外文，推荐的器材和线材请附上中文译名，并告知参考价格，以免被宰。
本人听音室3.1m×4.5m，硬调子结构。

浙江富阳市桂花路52-4 骆建光A你是谦虚吧，懂得关注房间的声学调性，还配了非常不错的功放和音箱，真不象是初哥。
B&W 805、音乐传真A3.2CR前后级、安桥P301/M501都是相当Hi-Fi的器材，搭配也没有任何问题，放心好了，你现有的器材完全能再现美妙的音乐。
监听的本色 PMC音箱的绝配
PMC厂方特别强调，COR是一台纯模拟的合并功放，无论是高低音控制还是音量控制，都是纯模拟线路设计，高低音控制方面更是采用世界顶级调音台的技术，以保证音色的纯正。COR采用A/B类放大，全分立元器件设计，功率管方面采用了达灵顿晶体管设计，达灵顿晶体管即是将两个三极管串联，以组成一只等效的新的三极管，这只等效三极管的放大倍数是原二者之积，因此它的特点是放大倍数非常高。虽然这是上个世纪研发出来的技术，但是经过新科技、新技术的变革，现在可以将达灵顿晶体管全部封装在一起，所以现在每声道只要使用1颗新的达灵顿功率晶体，就能够提供每声道95W（8Ω）的功率输出，4Ω负载时更可以提供达140W输出功率，其总谐波失真小至0.001%。
此外，厂方表示他们在研发音箱时需要用功放来搭配试听，可是在这个过程中却常常发现功放有各种的问题发生，而不是PMC的音箱本身的问题。故此，厂方也认为用户在搭配自家的音箱时，同样会发生各样的问题，从而不能展现PMC音箱应有的声音。既然如此，PMC本来就有有源音箱产品，在设计放大线路上并不是问题，那就干脆自己来设计一台功放好了！于是，花费了4年的时间才完成这台COR合并功放。
作为一家音箱公司的PMC，为什么会推出COR合并功放？其实，早在新世纪之前，世界上不少大型的录音棚、电台、电视台、电影混音室等监听音箱就已经逐渐向有源音箱转变，PMC也不例外，除了一些音箱内置专属的功放之外，PMC也为一些大型监听音箱系统特别定制专属的功放，厂家可以根据自己音箱的特性选择或开发功放，非常有针对性，制作人在混音的时候不需要将功放等的音色表现考虑其中。现时有源音箱已经成为录音室、制作室当中主流的监听系统，因此笔者对于PMC推出COR合并功放用于推动自家民用系列的音箱产品并不感到意外，相信这也会成为新的趋势。

BMW
宝马车系音响解码技术解析车型配备：宝马M3、528i、Z3这三款车选用了四种机型，分别为：KE-94型、KZBE-96型、BE0074型、KE-91型。
芯片应用93C46、LC46、DH001、24C16，为第一类存储机型。
只能用专用仪器来解密码。
代用芯片为2444P、X2444P、24C08。
528i和540i车型中所使用的仪表及音响也是基本相同的，这几种车选用了三种机型：PH7850、KEJ-8001S、KEJ-8001A。
一眼看上去很可能把5系和3系音响看成是一样的，其实是不同的，芯片应用93C46、DH001、DH004。
这几种机型解码要用仪器来解。
如需代用芯片，可用LC46、X2444P。
注意在取芯片时一定不要让烙铁温度过高，过高会影响或损坏芯片。
在宝马Z3和540i车型上选装二种音响。
其中一种型号为CM5901，另一种Z3装BE0074型。
因为540i和528i车上也选装过同种机型KZBE-96型，540i同时也安装CM5908型。
宝马M5、850ci这两种车型全部安装了CM5908型阿尔派音响。
CM5908型在比较老款的宝马车上应用比较多，仅次于CM5908J型机。
一般在 95年以前的宝马车系上如：525i、535i、745iL、750iL、850ci、740iL等车型上普遍选装。
但也有其它一少部分别类机型。
宝马525i车型选用了四种型号音响，CM5908、CM5908J、BP1830和BLAUPUNKT厂家生产的插卡式防盗音响，有很少部分奔驰车也有选装这类机型。
在这里我们不考虑这种机型，因为它并不需要密码，此卡可以把它看成一个功放电路开关罢了，BP1830机型是德国贝克公司生产的，属于第一类机型，其芯片型号为93C14。
代用芯片型号LC46或93C46。
密码查寻需专用仪器。
在宝马850Csi车型和323is车型上选装有CM5908J机型和先锋公司生产的KE-85和贝克公司生产的BE0774机型。

丝路音乐：PMC音箱述评
丝路⾳乐：PMC⾳箱述评为什么监听⾳箱有这样的地位? 这是源⾃它的作⽤和功能。
什么⾳箱可以称之为监听⾳箱呢？就本意来说，它是⽤于节⽬制作时监听⾳质的⾳箱，由此可见它的重要。
我们⾃⼰买⼀对⾳箱，如果有⽑病只会对⾃⼰和家⼈聆听有影响，⽽监听⾳箱有缺陷其影响就⾮同⼩可。
我们常讲某某公司、某某录⾳师录⾳效果好，之所以有好的录⾳效果，取决于录⾳师的经验与⽔平、对⾳乐的修养和理解，还取决于录⾳的器材和设备。
但是监听⾳箱的质量才是最重要的。
对于监听⾳箱既有技术指标⽅⾯的要求，⼜有⾳⾊⽅⾯的要求，它可以说是录⾳师另外⼀对⽿朵。
顺便提⼀下，⼈之所以能对⾳箱重放⾳乐，有⼀个好环优劣的评价，其原因就在于我们的头脑中储存了⼀个声⾳的母本，以后听到的声⾳是与母本相⽐较，从⽽得出⽐它好或⽐它坏的结论。
母本愈好判断能⼒愈⾼。
有⼈讲⾳箱听不出好坏。
能响就⾏。
不是听不出好坏，⽽是没有听过好的优质的⾳箱，没有建⽴⼀个良好的范本，这也是好⾳箱的价值之⼀。
这样就产⽣了⼀种兴趣，以对PMC做进⼀步的、全⽅位的、深⼊的了解。
对⼀个⾳箱的了解，和对其他事物了解有类似之处，即⾸先要判断它是真好还是假好，如果好，好在什么地⽅，再进⼀步收集资料，研究分析⼀下为什么好，供我们学习借鉴。
1 监听扬声器与⾼保真扬声器的异同 PMC的⾳箱最初是⽤来作监听⾳箱，后来⼜作了⼀些⾼保真⽤⾳箱，但作为监听⾳箱还有⼀些特殊的要求。
（1）不染⾊。
染⾊是从⽇常⽣活中借来的词汇。
⾐服沾上油渍、墨⽔渍、颜料渍等，即使洗⼲净，但污痕犹在。
⾳箱重放声⾳、⾳乐时我们也希望它是纯净的、⽆瑕的。
有了染⾊，我们在欣赏⾳乐时总会发现某种缺点，但正像⼈⽆完⼈、⾦⽆⾜⾚⼀样，绝对没有染⾊的⾳箱是不存在的，⾄少在当今是不存在的。
⽽有⼀部分国家⾼保真⾳箱有时则利⽤这种染⾊，就像宣纸上掉下⼀点墨迹，⾼明的画家涉笔成趣，这⼀点可变成⼀朵花或者⼀条鱼。
要做到这⼀点并不容易，要有悟性，不是什么⼈都可以办到的。

【摘要】笔者近期受朋友之托选购一套音响组合,由于朋友平时听音乐范围很广,他不喜欢音染过浓的声音,要求各种音乐重放真实耐听。
同时作为工薪阶层他希望日后能够更换或添加某一器材来提高音质,于是笔者为他选配了美之声监听1号改良版音箱、斯巴克 Cayin-265Ai放大器,CD 音源采用山灵 CD-50。
该套器材的选用重点是音箱,因为笔者朋友的听音室面积约为17m^2。
故选用书架式音箱以避免过强的低频驻波,同时考虑到声音还原的真实性,选用了以声音真实准确著称的珠海美之声监听1号改良版书架式音箱,该音箱采用经过改良的中低音单元和高音单元,分频网络采用低通-6dB/oct、高通为更好的-18dB/oct 并增加阻抗补偿网络,使指向性更理想,低频响应的线性更平滑,中频顺滑干净,瞬态响应快捷,高频的延伸性更佳,而且灵敏度也提高到87dB,具有监听器材特性,性价比也高。

音箱的挑选与搭配问题
风雨过后： 怀冰老师、爱徒老师你们好！最近看了几款书架箱，
丹拿40周年、劲浪1008和西湖&4,平时一般听一些弦乐 和人声多，很少大规模的，喜欢清爽、明亮点的风格，想 请教二位老师：1、哪款箱子好些，或者说更合适；2、现 在我用的是贵族1SC箱子+naimXS2功放+naim5XSCD,如 果换以上一款箱子的话，有没有一耳朵提升；3、推荐一、 二款适合以上箱子的功放，晶体管合并机（主要是便 捷），两万元左右。谢谢！！ ！
都觉得中意了，之后再来发图片问怀冰兄或者小弟我，可
以的话连音箱品牌型号一起发出来，后级300WX2,建议
找落地音箱。
线材有CD到前级平衡线、前后级平衡线、后级电源 线、前级电源线、CD电源线、音箱线一对，2米即可。电 源线3条，平衡线2对，例如：NBS蛇仔这一类就可以了。
另外，为你太太准备一个德生BT蓝牙解码，让她用手 机蓝牙连接BT50这样听歌曲吧。

一两千元能发烧吗?
乐通电子： 一直以来就喜欢听怀冰老师的HIFI天地，好像所介绍
的都是几千上万，甚至几十万。但苦于囊中羞涩，有没有 几百或一两千元就可以听到比较好的音乐。
tianjian：
你能接受的话，是有的，但是一两千还是少了一点
点，3千刚好。CD—千，国产山灵，斯巴克，度高都有二
音箱是英国Q牌的AV环绕音箱，900多元买的，低频

宝丽昌音响与您分享?英国PMCtwenty5.26落地音箱
宝丽昌音响与您分享英国PMCtwenty5.26落地音箱传输线(Transmission line)理论并非新事物，基于同一理论所设计的扬声器，无论是音响品牌出品还是DIY习作，可说是早已有之。
但假如以此佐证某些发烧友挂在口边的「新不如旧」、「还是以前那一套」，便捉错用神了。
音响是科技，随时代进步，新款器材的还原录音真貌能力只会愈来愈好。
就如传输线，在英国PMC手中变成ATL(Advanced Transmission Line)，效果超前市场其他采用传输线理论的扬声器。
当品牌的产品研发职责传至创办人之子，他引入来自一级方程的流体力学技术，设计出Laminair导流器，将之应用在twenty5系列，将低音分析力推至更高层次。
广告进步,永不停步电声科技与声学设计，一如其他科技领域，只会一次又一次地超越以往。
正如当年PMC的ATL，结合理论与实际经验，得出各种独家技术以及心得，改变传统传输线容易令低音过量、缓慢等问题。
ATL 技术之下，传输线长度不一定完全跟足低音四分一波长原则，同一时间，折叠方式、管道阔窄及形状、导管开口大小与位置，还有吸音物种类、厚薄、如何分配在声箱不同位置等等，都有独门计算方法。
展开剩余88%品牌创办人Peter Thomas成立PMC之前,就一直利用英国广播公司BBC的资源，去完善他的扬声器设计理论，故此一再与政府机构合作，那就不足为奇。
近年他们和英国国家物理实验室合作，以3D镭射测量技术RAOS(Rapid Acousto-Optic Scanning)直接记录空气变化，等同直接将声波在立体空间内的情况形像化，藉此协助扬声器设计。
导入顶级赛车技术Peter Thomas之子Oliver Thomas遗传了父亲的科学天赋，根据他在Linkedln的公开履历，早于2006年经已在PMC担任R&D工程师；2009年成为Red Bull车队的电子硬件工程师，曾参与设计一级方程式赛车；2011年于Oxford Brookes University毕业，主修赛车工程，同一年，他亦离开了Red Bull车队；2012年是他回归PMC的年份，成为了R&D主管，标志着品牌成立二十五周年的twenty5系列就是由他主导产品开发。
