※ 引述《ferrarirossa (Sean)》之銘言： : Google 到了 有興趣的看一下吧 : 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>< 那個好嗎? : 有大大可否推薦一下 : ※ 引述《ferrarirossa (Sean)》之銘言： : : 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 = = --
