一、無線ktv麥克風如何調頻
調頻
1、無(wu)(wu)線話(hua)筒(tong)(tong)調頻可(ke)分為兩(liang)種(zhong)方式，一種(zhong)是調節(jie)(jie)無(wu)(wu)線KTV話(hua)筒(tong)(tong)的頻率，另(ling)外一種(zhong)是調節(jie)(jie)無(wu)(wu)線KTV話(hua)筒(tong)(tong)接收主機(ji)的頻率。無(wu)(wu)論使(shi)用哪種(zhong)方式，只要無(wu)(wu)線KTV話(hua)筒(tong)(tong)的頻率和接收主機(ji)的頻率一致，就可(ke)實(shi)現無(wu)(wu)線話(hua)筒(tong)(tong)正(zheng)常(chang)工作。相對(dui)來說，調節(jie)(jie)無(wu)(wu)線話(hua)筒(tong)(tong)接收主機(ji)頻率的方式比較(jiao)簡單。
2、打(da)(da)開無(wu)線(xian)(xian)(xian)KTV話(hua)筒(tong)和接收主(zhu)機(ji)的(de)電(dian)(dian)源(yuan)開關，無(wu)線(xian)(xian)(xian)KTV話(hua)筒(tong)與接收主(zhu)機(ji)的(de)顯(xian)示屏分別顯(xian)示當前各(ge)自的(de)信道和頻(pin)率。正常(chang)情況(kuang)下，有些無(wu)線(xian)(xian)(xian)KTV話(hua)筒(tong)和接收主(zhu)機(ji)的(de)電(dian)(dian)源(yuan)開關打(da)(da)開后，無(wu)線(xian)(xian)(xian)KTV話(hua)筒(tong)接收主(zhu)機(ji)通過紅外掃(sao)描自動對(dui)頻(pin)的(de)功能，自動與無(wu)線(xian)(xian)(xian)KTV話(hua)筒(tong)當前的(de)頻(pin)率和信道匹配(pei)，通過兩者(zhe)的(de)液晶(jing)顯(xian)示屏可看(kan)出是否已(yi)匹配(pei)。

如果無(wu)線(xian)(xian)(xian)(xian)(xian)KTV話(hua)(hua)(hua)(hua)筒(tong)與無(wu)線(xian)(xian)(xian)(xian)(xian)KTV話(hua)(hua)(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)已自(zi)動(dong)(dong)對頻，就不需要我們(men)手動(dong)(dong)來(lai)調(diao)(diao)頻了(le)。若無(wu)線(xian)(xian)(xian)(xian)(xian)KTV話(hua)(hua)(hua)(hua)筒(tong)與無(wu)線(xian)(xian)(xian)(xian)(xian)話(hua)(hua)(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)沒有(you)自(zi)動(dong)(dong)對頻，就需要我們(men)通(tong)過手動(dong)(dong)調(diao)(diao)節(jie)無(wu)線(xian)(xian)(xian)(xian)(xian)話(hua)(hua)(hua)(hua)筒(tong)或無(wu)話(hua)(hua)(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)來(lai)實現二者的(de)(de)對頻。無(wu)線(xian)(xian)(xian)(xian)(xian)KTV話(hua)(hua)(hua)(hua)筒(tong)顯(xian)示屏顯(xian)示出來(lai)的(de)(de)頻率是多少(shao)(shao)，我們(men)就把(ba)無(wu)線(xian)(xian)(xian)(xian)(xian)KTV話(hua)(hua)(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)面板上的(de)(de)頻率調(diao)(diao)節(jie)按鈕把(ba)其(qi)頻率調(diao)(diao)到(dao)多少(shao)(shao)，二者頻率一致后，無(wu)線(xian)(xian)(xian)(xian)(xian)KTV話(hua)(hua)(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)就可以(yi)接(jie)收(shou)無(wu)線(xian)(xian)(xian)(xian)(xian)話(hua)(hua)(hua)(hua)筒(tong)傳送過來(lai)的(de)(de)聲音信號了(le)。
注意事項
1、無(wu)線KTV話筒的調頻是針對無(wu)線KTV話筒的接(jie)收(shou)主機(ji)來說的，在沒有接(jie)收(shou)主機(ji)頻率的情況下，僅僅只對無(wu)線KTV話筒調頻，是毫無(wu)意義(yi)的；
2、如果覺(jue)得調無(wu)線(xian)KTV話(hua)筒接收(shou)主(zhu)機不方(fang)便，也可(ke)以(yi)能過(guo)調節無(wu)線(xian)KTV話(hua)筒的(de)頻率的(de)方(fang)式，實(shi)現(xian)二者的(de)對頻。
二、無線ktv麥克風的種類
無線話(hua)筒按其使(shi)用的制式的類型分為三種，分別(bie)是FM無(wu)線(xian)話筒、VHF無(wu)線(xian)話筒和(he)UHF無(wu)線(xian)話筒。
FM 無線話筒(tong)，早期(qi)消費性無線話筒(tong)是利用(yong)FM收(shou)音(yin)機來接收(shou)，系統簡單，成本低廉，但因使用(yong)效果，不能滿(man)足專業品質的要求。
VHF無線話筒，又分為(wei)低頻及高頻段(duan)(duan)兩類型(xing)，使(shi)用天線長(chang)度太長(chang)，又最(zui)容易受到各種電器雜(za)波(bo)的干擾，因此這(zhe)一類型(xing)的產(chan)品，已(yi)經被高頻段(duan)(duan)所取(qu)代而(er)逐漸從(cong)市場(chang)上消失 。
UHF無(wu)線(xian)(xian)話筒，使用頻率為300-3000M的(de)無(wu)線(xian)(xian)話筒，是(shi)21世紀話筒應(ying)用的(de)主流(liu)，因為避(bi)免了V段的(de)對講機(ji)等的(de)干(gan)擾(rao)，所以(yi)穩(wen)定性有很大提高。
