发帖数: 60932 | 5 I was searching for a quality mower for a small lawn and this one has the
best reviews and was the cheapest option that had a bag etc.
I was going to buy from Amazon for 149 because sears had it for 129 but that
was online only so with shipping and tax worked out to be 154.
I was about to bite the bullet when I saw overstock had it for 129.99 +
shipping of 2.95

发帖数: 2078 | 32 1. 谁是文盲，就是这一个问题：
把fiio 耳放，放到卡座里面，用卡座内部电源供电，然后把fiio 的耳机输入连接到卡
座的输入口。同时把fiio 的输出，连到卡座的前面耳机输出口上。
这能不能实现？这能够实现，什么你讲的一堆卡座限制都是扯蛋的东西。
这就是平行线路。
不说其它的了，免得跑题。
2. 你的回答：
告诉我你文科还是理科，人话听不懂，这么简单的原理也理解不了。
Fiio是可以放进卡座，可以放进垃圾桶，可以放进车后备箱。放进卡座你就绕不开line
amp和一系列的filter，退耦，磁漏，fiio就变成了更垃圾的东西明白么？
不是说你把fiio放进卡座，放进垃圾桶，放进后备箱，这些卡座，垃圾桶，后备箱就动
变成了耳放。
3。我的关于line amp 的回答
牛人，竟然能想到line amp！
卡座的line amp 当然不够，所以在后面才要加耳放，耳放里面带的有自己的line amp。
你把独立耳放接到ipod上面，ipod 里面也有line amp。这有什么影响？

发帖数: 593 | 35 板上很多同学都用gnx，也用tube amp或者tube combo，不知道大家怎么搭配还是就各
用各的。
我的方法希望不Old，我用的是gnx3和traynor 50 tube combo，都是常用的gear。
动机：
因为gnx3的amp、cabinet模拟太让人不满意，开了吉他的音色和tube amp 音色都没有
了，所以我不选 gnx-->tube combo's pre--> tube combo's power amp-->耳朵
这样，tube amp 我觉得其实就只是有一些音色的喇叭或者扬声器。
而且买tube combo就是为了追求管子音色嘛。如果只把tube amp作为一个喇叭用，实在
浪费，电脑喇叭或者solid state amp 都可以了。
我的办法如下，
1.连接：
用tube 的pre 和power amp，把multi－effect串到effect loop里面，只用multi－
effect 里面的效果，不用他的amp、cabinet模拟
线路如下：

long answer:
"A power amp usually just takes one signal input (or two for stereo) and
amplifies it so that it can drive a speaker.
An preamp takes several
inputs, provides a mechanism to switch between them, a volume control,
some sort of tone and balance control (usually but not always), and puts
out a single signal at line level. You plug your sources into the
preamp, plug the preamp into the power amp, and the power amp into the

各种降功率的办法是这样的：
1）一般的master volume是简单的降低进入power amp的信号。问题就在于power amp是
非线性的，就是说必须开到一定音量才好听。当然这时候邻居就不答应。
2）power scaling是通过改变power amp里面的参数比如电压实现。
3）一般大功率那种amp的比如100w->50w切换是通过开关power amp的整个单元实现。
4）attenuator是离开了power amp以后通过使用dummy speaker load减小输入到扬声器
的电流。
使用2,3,4就可以保证把master volume开大，但是出来的音量稍小。

you might consider separate pre-amp and power amp (with separate power
