x******r 发帖数: 538 | 2 结论了,我错了。
试过16 Ohm, 32 Ohm,250 Ohm, 三种耳机均可察觉到一个恒定的噪音,receiver增益从
0到1的时候噪声就出现,虽然轻微但是可以察觉,增益加大噪声不变,receiver的放大
器应该没问题,应该是放大器往耳机输出端的转换用了低质量的原件(或者压根没法做
到最优,低压的耳放是不需要这部分的),也有可能是交流电源的噪音没有处理好。
低阻抗耳机,receiver的输出质量还不如portable player,高阻抗耳机,receiver输
出稍好,不过噪音是个疙瘩。总之receiver耳机输出端基本是个摆设了,用高阻抗的耳
机虽然可以听个差不多,但是肯定不如耳放了,至少我这个不行,我猜大部分receiver
耳机输出端都不会花大本钱去优化,因为这个指标不列在receiver的说明书上。 |

s*******t 发帖数: 300 | 3 先介绍一下基本情况,本人小白一个,对音响一窍不通。最近开始琢磨家庭影院。
media room面积大概350sqft左右。原来房主的布线是5.1的,为了省钱省事还是做5.1
的音响系统吧。
关于预算,是希望音响加receiver尽量控制在1500以下。因为想着感恩节前弄好,所以
也不没法等deal了。
本人声音敏感度不高,对音质最低要求是希望中音区舒服,高音区不刺耳,不太关心低
音(其实很讨厌那种要把窗户爆掉的低音), 在看电影时不要求音响powerful,但是起
码要能听清对话。沙发离屏幕大概4到5米之间。
后来在版面上看到大家讨论卡啦OK,也很感兴趣,于是就想着能不能家庭影院和卡拉ok
兼顾呢,所以就有了下面的‘奇葩’配置:
Polk Audio Monitor70 Series II Floorstanding Loudspeaker (Black) One Pair --
$336
8-ohm impedance,Frequency response: 30Hz-25kHz ,Power rating 20-275W, 1"
dome tweeter and four 6.5"... 阅读全帖 |

s*****d 发帖数: 469 | 4 See the pictures now. In order to test the compressor, you will need to
measure the resistance of each of the 3 poles against ground. It should be
between 3 ohms and 5 ohms. 1 ohm seems not normal. You will also need to
measure the RLA of the compressor with clamp meter. |

wh 发帖数: 141625 | 5 上周复习《幽灵公主》,写了个帖子说和《指环王》相仿。接着复习《风之谷》(
Nausicaa of the Valley of the Wind),又发现和《幽灵公主》更像了。《风之谷》
是宫崎骏1984年拍的,《幽灵公主》是他97年拍的,主题都是反思工业文明对自然界的
破坏、呼吁人与自然和谐共处;后者的叙述技巧比前者好很多。
《风之谷》从头到尾有大量人物独白:黑骑士Lord Yupa(像指环王里的Gandolf)介绍
此时为工业文明毁灭后的1000年,大片毒森林正在吞噬世界,侵蚀残余人类;末日战士
Nausicaa公主介绍她的家乡风之谷地处海边,被海风吹拂的空气干净和平;老女巫
Obaba讲述王宫里壁画上的故事,一位蓝衣骑士将降临人间、拯救世界……这些故事背
景与情节都靠人物独白展现,很不自然流畅。据说原漫画连载了漫漫13年,内容庞大深
厚;好不容易拍成5小时的导演版,为适应市场再缩成两小时的剧场版,因此简易化了
。不过独白的问题不是简易,是笨拙。13年后的《幽灵公主》就轻松摆脱具体时空的束
缚,叙述自如得多。
然后说说《风之谷》与《幽灵公主》主题上的相似:

买MSMW Series,可以wire bond。他们和我说可以在低温电阻也不怎么变,我正准备试
试。其实就是变大了一点,也可以买一个室温小于50 Ohm的。
你cryostat的温度要在多少?如果低于0.3K,不能用thick film,要用thin film。
50 Ohm在cryostat里头有很多好处。比如Johnson noise小了什么的。
不过有点不明白,你好像要测反射信号?那如果你把终端50 Ohm了,那是没有反射信号

如终端短路或者开路,反射波形不仅展宽,而且有明显的抖动(具体原因可能是

s*******t 发帖数: 2896 | 14 冬天刚过,车子风吹雨淋,再被冻上个把月,闹毛病也在所难免。对于版上流行DIY
spark plug wire(缸线),今天把我有限的diy经验和物理知识总结如下:
缸线是易损件,几万mile以后会老化失效,是常见故障。以前火花塞寿命短,只有3万
迈左右,而缸线寿命长一点,所以点火问题大家通常怀疑是火花塞坏了。现在的火花塞
寿命大都在10万迈左右,所以缸线通常会先坏。这对diy更有利,因为缸线的检查和更
换都容易得多。
缸线有一定的电阻:参考值是17 Ohms/mm。比如你的缸线长度30厘米,阻值就应该是
17x300=5100 Ohms,如此可以确定某一根是不是坏了。或者可以假设各根缸线的单位长
度上的电阻应该一样,从而找出坏的那根。大家可以买auto range的万用表(大概20$
),不用调量程,省时省力。
为什么缸线要有电阻?因为火花塞平时断路,点火时空气被击穿从而短路。如果缸线上
电阻太小就烧坏了。
缸线的更换更简单,只要记住拆一根换一根就好了。缸线的两端连接处要涂硅脂,起到
绝缘防潮的作用。
错误难免,牛人轻拍。 |

The truth is at normal listening levels, very little power is needed to get
the most out of a relatively efficient speaker. Whether you have an 80W amp
or a 220W amp, the channel still follows Ohm's law. Normal listening volume
means voltage is low, which means current is also low. The load to the
receiver should be close to constant around 8 ohms. We're really talking
like 10-20 watts.

105W per channel (8 Ohms, 1kHz, 0.9% THD, 1-ch. driven)
90W per channel (8 Ohms, 20Hz - 20kHz, 0.09% THD, 2-ch. driven)
105W这个是peak值吗?THD和1ch 2ch driven是什么意思?如果唱歌的话最好每个
channel 100W以上是看第二个参数? |

t*****e 发帖数: 2206 | 47 DENON是5.2 Channel并且是REFURBISHED,最关键的是power不够,只有70 Watts per
Channel (8 Ohms)。
Onkyo TX-NR626是7.2-Channel并且是new的。95 Watts per Channel (8 Ohms)。还有
wifi和MultEQ from Audyssey。
包子应该给俺哈。 |

during the test. Live testing with high voltage is very dangerous.
Now, you need to unplug those two wire leads to the thermal fuse,
preferrably take it out of the socket. Then measure resistance across the
two open terminals of the fuse, not the two wires. You can either set your
multi-meter to the resistance with tone mode and check for continuity tone/
beep when you touch the two terminals.
Or set your multi-meter to lowes... 阅读全帖 |

用万用表测一下speaker两个接线之间的电阻。一般的receiver可以drive 3 ohms到16
ohms的speaker,小欧姆的音响输出功率大 |
