※ 引述《ferrarirossa (Sean)》之铭言： : Google 到了 有兴趣的看一下吧 : http://www.tweakheadz.com/catalog-mic-preamps1.htm : What is a Microphone Preamp? : Think a minute. A microphone actually converts sound energy into voltage. : But this voltage is very low, MUCH lower than the voltage coming out of your : keyboard or other line level processors. Your recording device can't use : this signal unless it boosted massively. Hence the preamp. You already have : a mic preamp on your computer, but it's only designed for speech and cheap : mic--totally unsuitable for serious work. You might have Mic preamps on your : mixer and they may work perfectly. However, sometimes we want a better one : than is on our mixer. And if you don't have a mixer and are going mixerless, : then you have to have a mic pre. On this page you will see a lot of : different preamps that will boost a microphone signal without adding lots of : noise. Remember that the Mic Pre is one of the "core" devices that provide : for sound quality. You will see that there are many preamps here. There is : one for every budget. : 我看到有美金30~40左右的耶>< 那个好吗? : 有大大可否推荐一下 : ※ 引述《ferrarirossa (Sean)》之铭言： : : 我买了SM58 然後马上试用没有声音 : : 可是同样的插巢换上电脑用的mic就有声音>< : : 我是插在电脑上 买一个1/8"的转接头接上去 直接插上主机版上的内建音效卡 : : 有什麽地方不对吗?@@ 印象中 像这种动圈式的麦克风… 好像都是要接专业的录音卡 然後录音卡会有麦克风讯号扩大器 然後声音讯号才会有扩大 我自已败了一个录音卡 结果只有插麦克风的洞有讯号扩大功能 插jack phone的就没有(一般6.3mm的) 插xlr的才有(也就是插麦克风三个洞的那个头) 所以… 败录音卡吧 = = --
