美国顶级西湖音箱北京代理，Lc3w12\Lc8.1\Lc6.75全新原包现货，... [复制链接]

不知道西湖兄昨天的测试结果如何？我现在是习惯直接接地线的声音了，真是背景更宁静，细节更多，也更紧凑，原来的宽松度有些许减少，等待你的正确答案。现在为了避免危险，我只在听音乐的时候接上PE线，平时不开的时候拔下来。另外mao兄说是对此线的材料也有要求，不同的线声音也不一样，不知对此您也有何见解，如果方便，一起问问西湖厂家吧。我也在北京，等您器材到齐了想去拜访，蹭听一下啊，不知道欢迎否？

NAGRA金字塔功放的接地端口,与电源地线/外壳镙丝/XLR/RAC地线相通!
NORDOST 插排也提供了一个类似的接地端口,同样也有香蕉输出,经测量地电源地相通!
P.E的接法我仍然没法肯定,刚才查了BOULDER 2060的手册,里面也没有说法. 看来只有等厂家的答案了.
欢迎月光兄来交流, 因平时没有人在位, 请提前预约15911083319.

At the rear of the unit is a 3 position terminal strip which provides  electrical access to the chassis (center terminal) and left and right audio grounds respectively. Lowest noise (mainly hum) may be achieved  with the chassis connection open or connected to the system audio ground, or lacking this, to the left or right, or both left and right terminals. Some experimentation may be required to find the combination most suitable  to a particular installation. Many high quality power amplifiers (or pre-amps) provide user selectable connection from chassis to audio common. It is usually best to start by opening the audio to chassis links on all equipment  and listen to the hum and noise present in the output of the speaker system.

大意是许多优秀的高素质功放都提供"共地"接口(我认为与NAGRA相似),用来与音箱相连. 断开/连接可以听到系统哼声的区别.

还是等厂家回复吧

Glenn has given me information to hopefully answer your question.  The short answer is:  Yes, to the amp chassis, close to the output terminals unless there is a dedicated audio ground or "P.E." jack.  
We hope to eventually solicit "P.E." licensees to provide dedicated P.E. terminals on the equipment, but that time is not at hand just yet.  Although the P.E. signal can be drained through the ground or chassis connection, what we are really looking to do is provide a safe return to the amplifier' power circuitry which may or may not be the amp ground or chassis.  If the amplifier output terminals have one terminal connected to ground or chassis (our old style Boulder amps are this way) then the P.E. connection can be just piggy-backed on to the (-) terminal.  This is how we demo'ed the system we had at CES 2011 in Las Vegas.  If, however, you are using an amplifier that has both (+) and (-) terminals actively driven, then connecting the P.E. wire/jack to the amp audio ground or chassis is the way to go.
By the way, if your customer neglects to connect the P.E. jack at all, he will still be getting much of the benefit due to a circuit we include in the speaker that we refer to as the "safety virtual P.E. Bus".  This is a version of our "Virtual P.E. Bus" we developed for the smaller speakers where limited space precludes the use of a 3rd terminal.  We drain the rogue P.E. electrons out through the 2 signal conductors.  Not quite as effective as a "real P.E. Bus" and dedicated connection, but unless you have a very good listening environment, I doubt you can detect the difference on most program material.
The Lc4.75, Lc24.75, Lc265.1, Lc5.75 and Lc6.75 use a virtual P.E. bus technology and thus have no physical jack on the back.  Some earlier production units of other models used a modified version of the virtual PE Bus, and thus may not have a dedicated jack.

P.E线接法:
机壳/镙丝/或者" -----" 接线柱;
what we are really looking to do is provide a safe return to the amplifier' power circuitry which may or may not be the amp ground or chassis.
最好是有一个专用的独立的电源地(不是功放地或机壳), 西湖希望所有的功放厂家能提供这样一个接口.

西湖兄辛苦了，谢谢你终于找到了答案，那我的理解是不是就是可以接到外壳上，但是要像NAGRA那种有独立接地端子的功放，如果没有的话，就应该接到一个独立的电源的地线？

1、功放输出的负端子（—）；
2、功放机壳或机壳镙丝（用万用表测量与电源线的地线相通）；
3、专用接线柱（我一般连到插排的接地点）；

厂家推荐使用接法1，可以购买他们家的带PE线的喇叭线，好不好我不评价。市场上只有他们一家有这样的产品。

这下彻底搞明白了，谢谢西湖兄。现在很喜欢西湖的声音，觉得西湖的平衡、宽松以及密度感都很好，这正是我想听到的声音，不过国内对西湖各个型号产品的评价和介绍也不多，也比较少有机会能听到，希望西湖兄和烧友们能够多收集一些西湖产品的资料和评价，如果能搞一次展示会就更好了，让更多的朋友能够了解、喜爱西湖。

感谢月光兄对西湖产品的喜爱！

因本公司订购的自用展示品HR-7意外地销售了，现在只有一对TOWER-12大箱也很快会被主人颔走。缺乏最能表现西湖特点的号角箱，现在暂无计划举行交流会，当然小范围的交流是经常有的，欢迎有兴趣参加的烧友发短信留下联系方式，有机会有我会通知大家。

谢谢！

ACTIVE BI-AMP
SINGLE AMP WITH HLX 400
ACTIVE QUAD AMP WITH HR-X CROSSOVER

Well, each has its advantages.

Active Bi-amp: Of course, requires a minimum of 2 amplifier channels per speaker, so amp requirements are double–although there is some thought that because the load of the speaker is less without the HLX 400, that the amplifier capability can be less. The presence of the MRX-2-400 active crossover in the system allows some adjustment of L.F. versus H.F. level. Less high-level crosover sound but more active electronics in this version is a sonic trade-off that only the listener can evaluate. They are different even though we do our best to minimize the sonic fingerprint of each. Optionally, this version can be passively tri-amped (more block diagrams available).

Single Amp with HLX-400: Can be powered with just one stereo amplifier (bi-wired speaker cables recommended). Optimally it can be passive bi-amped (we have block diagrams if needed) for higher resolution. Single Amp operation allows the use of a very high quality amplifier (say Jadis JA-800 or Boulder 2000) at the start and upgrade to a 2nd set for passive bi-amplification as budget allows.

Active quad-amp with HR-X crossover: This system will have the least high level networks (although still some driver correction pats in speaker cabinet) and the maximum number of active circuits. Again, we do as much as is practical to minimize the sonic impact of both. The speaker requires the 4-way active crosSover and 4 amplifier channels per speaker. There is no single amp or bi-amp mode for this version. Four stereo amplifiers or 8 mono amplifiers should have equal gain if possible although there is a control range of about 6 dB for each of the 4 outputs on the signal boards of the HR-X 4-way, 2 channel active crossover. Connecting 4 amplifiers (or  plus the active crossover, pre-amp and source components into such a revealing system can be quite challenging, and it best done by someone with patience and experience. The other 2 versions are a bit less sensitive to system issues like cabling, routing, grounding and component placement.

All 3 systems can be double-wired (spades and bananas) from amp to speaker for additional resolution.
