自动设好后，在receiver上我还需要手工做这些：Set all the speakers to small
with 80Hz crossover frequency, subwoofer mode to LFE not LFE+Mains, LPF for
LFE to 120Hz, raise sub trim level in the avr from -6 to 00 |

和后级放大作在一起,基本决定了它的低端定位.
入门级的receiver基本是日系机器的天下， Onkyo， Denon， Pioneer, Yamaha,
Marantz等， 大同小异，价格大多在 在$300-$1000. 美国牌子少,有 Harman etc.
貌似Denon和Onkyo 更popular 一些。 newegg 和 accessories4less.com 经常有
deal. 我的第一台receiver 就是其中一个网站买的。关于 receiver 的功率标称， 入
门级的水分比较大，经常把两声道驱动时的功率标成5/7 声道同时驱动的功率， 看看
就可以了,别太较真,当然推一般音箱基本是没问题的。
receiver 基本算是 更新最频繁的器材了，Denon和Onkyo经常一年一个型号,所以贬
值非常快， 喜欢折腾换器材并且不介意二手的话，买二手会比较划算。美国高端的AV
器材正好相反， 好几年才憋出一个新型号.

7.1 is fine, but most of source is 5.1 which can deliver sound very well.
Hanging two spare speakers not used most time doesn't sound good idea to me.
All in One includes AMP and LFE, you can get LFE separately but uaually not
expensive. |

发帖数: 49 | 6 去年买了一辆新车，没钱，就finance了，车行财务经理说我必须买了一个1000多的
life insurance和2000多的extended warranty才能finance，我就买了，后来打电话给
银行，银行说不用，我自己就能取消lfe insurance, 取消extended warranty必须经过
dealer. 我就自己把life insurance取消了，然后跟车行的财务经理说把extended
warranty也取消了，他说好，后来又打电话确认，他说已经取消了。
现在想卖车，就查了一下要还多少钱才能pay off loan. 银行说dealer根本没有取消那
个warranty.
昨天早上去找那个财务经理，他态度很恶劣，之后就吵了起来，我又去找他们的销售经
理，销售经理说看看能不能取消。
哎。。那个extended warranty的合同上说30天后就不能解除了。
大家帮我看看，有希望要回那2000快嘛？
多谢啦～ |

AC-3是Dolby开发的数字音频压缩技术,AC-3代表Audio Coding, 3是序号. 现在通常标为
dolby digital. 区别就在digital. 另外它是所谓5.1声道, L, R, LS, RS, C, LFE. 最
后是低频, 算0.1. 主要用于HDTV, DVD, film. 你可到Dolby的网点去查. 包括采用AC-3
的film list. 不过我国不会将之作为hdtv标准, 好象要用欧州的. |

发帖数: 2626 | 8 恩，我google过，好像是说有的功放有LFE(低频效果)口，就是接subwoofer.
有的功放就没有，就是直接找一对左右声道的接到subwoofer上。 我的是后者，但是不
知道
这样有什么道理。 |

从subwoofer背面看到一下接法
1. 功放的subwoofer出口 -》 subwoofer的LFE入口 （一个出口-》一个出口）
2. 功放的preout的subwoofer出口 -》 subwoofer的linein入口 （两个出口对两个出
口）
3. high level connections （高电平输入输出）
问题如下：
1. 接法2用什么线来接？能否给个link（比如Amazon）？
2. 接法1，2中那个更好？
3. 给解释一下高电平是啥东西？

发帖数: 265 | 12 我的subwoofer是active的，有L/R rca和LFE in的口，但没有speaker wire的口，
receiver后面好像只有speaker wire的out，大家帮我看看有没有办法接？或者有没有
别的办法转接，多谢了。 |

发帖数: 7371 | 13 to put it simply this way: if your subwoofer supports LFE input, then you'd
be
able to use a RCA cable to connect from reciever subwoofer pre-out to either
left or right input on the subwoofer |

发帖数: 36899 | 14 Receiver sub pre out <-> sub LFE input
Should be okay.
Make sure you configure receiver to subwoofer on. And use speaker set A
