KLDguitar 100w 吉他衰减器测频
由http://rycooder.nl/pages/kld.htm做的KLDguitar 100w 吉他功放衰减器测频：Here's my attenuating pride and joy: my KLD PB1. This is the answer to my former problem of the volume levels coming from my 15 watt Fender Blues Junior. We all know this problem. Having a loud amp that forces you to use the master-volume know between 0 and 1 before becoming to loud.
The effective solution is an attenuator. This devices are placed between your amp and it's speaker, to take a part of the speaker load which is transformed to warmth and dissipated by the (great looking) aluminum housing.This version is particularly practical because of his two control-modes.
They call them "Stage" and "Studio" modes.
The Stage-control gives you the choice of 5 settings:
Min: True Bypass[*]4: 1.8 dB of attenuation
[*]3: 3.6 dB of attenuation
[*]2: 5.4 dB of attenuation
[*]1: 7.2 dB of attenuation
These settings are practical and sufficient for stage-use. They allow you to use all your favourite amp settings, whilst being able to adjust your overall volume to the venue with the PB1.
The Studio-control uses a rheostat/l-pad to provide far more attenuation, varying from 7.2 to 30 dB.
To illustrate what this means:
On my 15 watt amp, with the amps gain, the amps master-volume ánd the PB1 at 12 o'clock, the overall volume will allow a normal conversation whilst playing.Both modes have very little effect on the characteristics and tone of my amps. There is some effect, but this was compensated by the tiniest adjustment of my tone control.
Cons? One might dislike the lack of graphic design or notice that the "stage" and "studio" controls use opposite meaning of the word "Minimum". If these are a problem to you, feel free to spend a multiple of the PB1's price to get an equal quality.The PB1 is very affordable and practical, looks and feels sturdy and is very transparant. An excellent solution to a well annoying problem.

主要当年没学好。 和drz原版的一樣麼原版的衰減不是很大回复 6楼 采菊花的小伙 的帖子
不错，原版衰减率有点小，大概只有-20几dB 吧，我们将他提高到-30 dB. KLDguitar AT100-P衰减器是在开发了AT100的基础上，进行简化，只保留了衰减器部分，省略了模拟音响等。开发设计生产的一款无极衰减器.他可以提供最高完全静音的衰减。适用于超过100瓦的功放，控制旋钮：在顶板上，有两个控制旋钮，提供不同场合的衰减。
ATTENUATION(衰减率): 六档衰减，MINI 为-3dB 衰减,由档位4-1，每档为 -3dB 衰减，用于舞台表演。STUDIO档位 ,开始STUDIO 调节。
STUDIO LEVEL(工作室电平) :从-18 dB 开始可以连续衰减到静音.
输入输出接口：
AT100-p 将输入输出接口安排在机箱的两侧。
IN : 用喇叭线将功放的输出和AT100-p的IN联接，
OUT：用喇叭线将喇叭箱的输入和AT100-p 的OUT联接起来。
阻抗匹配：8Ohm（目前）
我们建议功放的输出阻抗应和喇叭箱的输入阻抗一致。及8ohm的扬声器一定要接在功放8ohm输出接口上。
