一、無線ktv麥克風如何調頻
調頻
1、無(wu)(wu)(wu)線(xian)(xian)話筒(tong)(tong)調(diao)頻(pin)可分為兩(liang)種(zhong)方式(shi)，一種(zhong)是(shi)調(diao)節無(wu)(wu)(wu)線(xian)(xian)KTV話筒(tong)(tong)的頻(pin)率，另外一種(zhong)是(shi)調(diao)節無(wu)(wu)(wu)線(xian)(xian)KTV話筒(tong)(tong)接(jie)(jie)收主機(ji)的頻(pin)率。無(wu)(wu)(wu)論使用哪種(zhong)方式(shi)，只要無(wu)(wu)(wu)線(xian)(xian)KTV話筒(tong)(tong)的頻(pin)率和接(jie)(jie)收主機(ji)的頻(pin)率一致，就(jiu)可實現無(wu)(wu)(wu)線(xian)(xian)話筒(tong)(tong)正常(chang)工作。相對(dui)來說(shuo)，調(diao)節無(wu)(wu)(wu)線(xian)(xian)話筒(tong)(tong)接(jie)(jie)收主機(ji)頻(pin)率的方式(shi)比(bi)較(jiao)簡單。
2、打(da)開(kai)(kai)無線(xian)(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)和接收(shou)主機的電(dian)源開(kai)(kai)關(guan)，無線(xian)(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)與接收(shou)主機的顯(xian)示(shi)屏(ping)分(fen)別顯(xian)示(shi)當前各(ge)自(zi)的信(xin)道和頻率。正(zheng)常情況下，有些(xie)無線(xian)(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)和接收(shou)主機的電(dian)源開(kai)(kai)關(guan)打(da)開(kai)(kai)后，無線(xian)(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)接收(shou)主機通過(guo)紅外掃描(miao)自(zi)動(dong)對頻的功能，自(zi)動(dong)與無線(xian)(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)當前的頻率和信(xin)道匹配(pei)，通過(guo)兩者的液晶(jing)顯(xian)示(shi)屏(ping)可(ke)看(kan)出是否已匹配(pei)。

如(ru)果(guo)無(wu)(wu)(wu)線(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)與無(wu)(wu)(wu)線(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)接(jie)收(shou)主(zhu)(zhu)(zhu)機已自(zi)(zi)動對頻(pin)(pin)，就不需要我們手動來調頻(pin)(pin)了。若(ruo)無(wu)(wu)(wu)線(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)與無(wu)(wu)(wu)線(xian)(xian)話(hua)(hua)筒(tong)(tong)接(jie)收(shou)主(zhu)(zhu)(zhu)機沒有自(zi)(zi)動對頻(pin)(pin)，就需要我們通過(guo)手動調節(jie)(jie)無(wu)(wu)(wu)線(xian)(xian)話(hua)(hua)筒(tong)(tong)或無(wu)(wu)(wu)話(hua)(hua)筒(tong)(tong)接(jie)收(shou)主(zhu)(zhu)(zhu)機來實(shi)現二(er)者的對頻(pin)(pin)。無(wu)(wu)(wu)線(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)顯示屏顯示出(chu)來的頻(pin)(pin)率(lv)(lv)是多少，我們就把無(wu)(wu)(wu)線(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)接(jie)收(shou)主(zhu)(zhu)(zhu)機面板上的頻(pin)(pin)率(lv)(lv)調節(jie)(jie)按鈕(niu)把其頻(pin)(pin)率(lv)(lv)調到(dao)多少，二(er)者頻(pin)(pin)率(lv)(lv)一致后，無(wu)(wu)(wu)線(xian)(xian)KTV話(hua)(hua)筒(tong)(tong)接(jie)收(shou)主(zhu)(zhu)(zhu)機就可以(yi)接(jie)收(shou)無(wu)(wu)(wu)線(xian)(xian)話(hua)(hua)筒(tong)(tong)傳送過(guo)來的聲音信(xin)號了。
注意事項
1、無線KTV話筒的(de)調(diao)頻是針對無線KTV話筒的(de)接(jie)(jie)收主(zhu)機來說(shuo)的(de)，在沒有接(jie)(jie)收主(zhu)機頻率(lv)的(de)情況下，僅僅只對無線KTV話筒調(diao)頻，是毫無意(yi)義的(de)；
2、如果覺得調無(wu)(wu)線(xian)KTV話筒接收主機不方(fang)便(bian)，也可以能過調節無(wu)(wu)線(xian)KTV話筒的頻率的方(fang)式(shi)，實現二者(zhe)的對頻。
二、無線ktv麥克風的種類
無線話筒按其使(shi)用(yong)的(de)制式的(de)類型(xing)分為三種，分別是FM無(wu)線話(hua)筒、VHF無(wu)線話(hua)筒和UHF無(wu)線話(hua)筒。
FM 無(wu)線話筒(tong)，早期消(xiao)費性無(wu)線話筒(tong)是利用FM收音機來(lai)接(jie)收，系統簡單，成本低廉，但因使用效(xiao)果，不能滿足專業品(pin)質(zhi)的要求。
VHF無線話筒(tong)，又分(fen)為低頻(pin)及高(gao)頻(pin)段兩類型，使用(yong)天線長(chang)度太長(chang)，又最容(rong)易受到各種電器雜(za)波的(de)干擾，因此這一類型的(de)產品，已經(jing)被高(gao)頻(pin)段所取代而逐(zhu)漸從市(shi)場上消(xiao)失(shi) 。
UHF無(wu)線話(hua)筒，使(shi)用頻率為300-3000M的(de)(de)無(wu)線話(hua)筒，是(shi)21世紀話(hua)筒應用的(de)(de)主流，因為避免(mian)了V段的(de)(de)對講機等的(de)(de)干擾，所(suo)以(yi)穩定性有很(hen)大提高。
