Re: [問題] 蠢問題 - 關於麥克風

: 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>< 那個好嗎?
: 有大大可否推薦一下

: : 我買了SM58 然後馬上試用沒有聲音
: : 可是同樣的插巢換上電腦用的mic就有聲音><
: : 我是插在電腦上 買一個1/8"的轉接頭接上去 直接插上主機版上的內建音效卡
: : 有什麼地方不對嗎?@@
印象中
像這種動圈式的麥克風…
好像都是要接專業的錄音卡
然後錄音卡會有麥克風訊號擴大器
然後聲音訊號才會有擴大
我自已敗了一個錄音卡
結果只有插麥克風的洞有訊號擴大功能
插jack phone的就沒有(一般6.3mm的)
插xlr的才有(也就是插麥克風三個洞的那個頭)
所以… 敗錄音卡吧 = =
