1. Two ceiling speakers in every bedroom and office. They will be powered by
a class T amplifier in each room.

是的,我是指的stereo amplifier. 如果stereo amplifier 只有analog输入,那你可
以用电视的analog输出。如果你电视只有optical 或coax digital out, 那你有两个选
择。一个选择是买个便宜的十几刀的外置DAC,其analog out 连到stereo amplifier。
第二个选择是买个带内置DAC的digital stereo amplifier (一般也含analog输入),
然后电视的optical 或coax out 连到这个amplifier 上。我用的放大器是带内置DAC的

来自主题: PhotoGear版 - 请问版上有EE的吗?
有个问题需要请教:
俺是纯外行,不过现在的工作需要用到超声,基本就是用FG产生信号,amplifier放大
,然后接到transducer。FG是一个EE的博士生设计的,amplifier是ENI 2100L,50db,
2手的
现在问题是:FG的信号设定是1V,1.5Mkz. Amplifier输出的应该的是316V,但是我观
测到的只有3V,如果amplifier的输出不连接任何cable,输出可以到67V,不过还是远
小于正常值。我同事已经用oscilloscope测出FG产生的信号正常。难道是amplifier的
问题?如果是的话如何检测呢?我们的这个transducer设计的是在1.5Mkz工作。
多谢大家的帮忙。

我一开始试的100mv,输出基本是0, 但是频率变小的话到几十赫兹可以看到amplifier
的输出变大。但是我们这个设计是在超声的情况下运作。昨天用oscilloscope测了FG的
输出,都没有问题。会不会是因为接了有50db的amplifier后影响了FG的输出呢?主要
我们FG是自己弄的,amplifier花了3000刀买的,所以都是希望不要是amplifier的问题
。如果测试amplifier如何弄呢?

来自主题: HiFi版 - 家庭影院折腾接近完成
我同意数字部分对音质不会有太大的影响。数字传输中即便存在bit error,jitter/
delay,大部分也都可以通过re-TX和在player那里加一个buffer解决。不同系统的音质
主要还是由音箱,DAC,和amplifier决定的。我个人的感觉是音箱的影响最大,DAC和
pre-amp次之,后级放大只要工作在线形区,保证一定程度的SNR,一般都没有什么问题
。这也是为什么大部分人都建议2/3 budget on speakers, and 1/3 budget on
electronics.

unmatched by the traditional speakers, although I think ML ElectroMotion is
probably even better in clarity. However I think Maggie 1.7 is very
sensitive to the quality of amplifiers. Yesterday I audited Maggie 1.7 first
on a 1600 amplifier and then a 16,000 one, definitely heard the difference.

来自主题: Biology版 - 问个cloning 的问题
Can you find the restriction enzyme site less than 2kb distance from the
insertion site? If yes, you do not have amplify very long fragments. Similar
size of fragments can joint together easier than different size fragments.
Another way: You can amplify the whole plasmid( How big is the plasmid?) by
the primers at the insertion site. Then you can introduce the enzyme site in
the primer. After PCR amplify the plasmid, digest it and ligate your 800bp
fragment and transform. You need to amplify you... 阅读全帖

Next Ice Age Delayed by Global Warming, Study SaysChristine Dell'Amore
National Geographic News
September 3, 2009
Humans are putting the brakes on the next ice age, according to the most
extensive study to date on Arctic climate change.
The Arctic may be warmer than it's been in the past 2,000 years—a trend
that is reversing a natural cooling cycle dictated by a wobble in Earth's
axis.
Previously, researchers had looked at Arctic temperature data that w... 阅读全帖

Hifiman HM-801 vs. iPod, Zune: A sound winner?
Sure, iPods and Zunes can sound perfectly fine, but no one ever claimed they
were bona fide portable high-end audio devices. Their "good enough" sound
isn't entirely their fault: they're too small to house a battery potent
enough to power a high-quality headphone amplifier and a high-resolution 24-
bit/96kHz digital-to-analog converter.

Charles H. Townes, a visionary physicist whose research led to the
development of the laser, making it possible to play CDs, scan prices at the
supermarket, measure time precisely, survey planets and galaxies and even
witness the birth of stars, died on Tuesday in Oakland, Calif. He was 99.
His daughter Linda Rosenwein confirmed his death.
In 1964, Dr. Townes and two Russians shared the Nobel Prize in Physics for
their work on micro... 阅读全帖

个人比较倾向Limited,因为想要皮椅和Power rear gate,但是package实在有点看不懂
1. 为什么Limited的package没有All-weather package?还是说默认已有了?

也都是攒的,比较满意AR的卡座,是卖家的Sampler,但没怎么用过。本想搞
个Rogers
LS3/5的Speaker,实在买不起Amplifier去推,幸好LS-66的Resolution很好,因
为房间差,定位和深度都不行的说。Marantz的Amplifier和CDP还行,在三五百
