一、無線ktv麥克風如何調頻
調頻
1、無(wu)線(xian)話(hua)(hua)筒(tong)(tong)調(diao)頻(pin)可分(fen)為兩(liang)種(zhong)方式,一種(zhong)是調(diao)節無(wu)線(xian)KTV話(hua)(hua)筒(tong)(tong)的頻(pin)率(lv)(lv)(lv),另外一種(zhong)是調(diao)節無(wu)線(xian)KTV話(hua)(hua)筒(tong)(tong)接收主(zhu)機的頻(pin)率(lv)(lv)(lv)。無(wu)論使用哪種(zhong)方式,只要無(wu)線(xian)KTV話(hua)(hua)筒(tong)(tong)的頻(pin)率(lv)(lv)(lv)和接收主(zhu)機的頻(pin)率(lv)(lv)(lv)一致,就可實現無(wu)線(xian)話(hua)(hua)筒(tong)(tong)正常工作(zuo)。相對來說,調(diao)節無(wu)線(xian)話(hua)(hua)筒(tong)(tong)接收主(zhu)機頻(pin)率(lv)(lv)(lv)的方式比較簡單。
2、打開(kai)(kai)無線KTV話(hua)筒(tong)和接(jie)(jie)收(shou)(shou)主機的(de)(de)電(dian)源(yuan)開(kai)(kai)關,無線KTV話(hua)筒(tong)與接(jie)(jie)收(shou)(shou)主機的(de)(de)顯(xian)示屏分別(bie)顯(xian)示當前(qian)各自的(de)(de)信(xin)道和頻(pin)率。正常(chang)情況下(xia),有(you)些無線KTV話(hua)筒(tong)和接(jie)(jie)收(shou)(shou)主機的(de)(de)電(dian)源(yuan)開(kai)(kai)關打開(kai)(kai)后,無線KTV話(hua)筒(tong)接(jie)(jie)收(shou)(shou)主機通過紅外掃描自動對頻(pin)的(de)(de)功能(neng),自動與無線KTV話(hua)筒(tong)當前(qian)的(de)(de)頻(pin)率和信(xin)道匹配,通過兩者的(de)(de)液(ye)晶(jing)顯(xian)示屏可(ke)看出是否(fou)已匹配。
如果無(wu)線KTV話(hua)筒(tong)(tong)(tong)與無(wu)線KTV話(hua)筒(tong)(tong)(tong)接收(shou)(shou)(shou)主(zhu)(zhu)機(ji)已自動對(dui)頻(pin)(pin)(pin),就(jiu)不需要(yao)我們(men)(men)手動來(lai)調(diao)(diao)頻(pin)(pin)(pin)了。若無(wu)線KTV話(hua)筒(tong)(tong)(tong)與無(wu)線話(hua)筒(tong)(tong)(tong)接收(shou)(shou)(shou)主(zhu)(zhu)機(ji)沒有自動對(dui)頻(pin)(pin)(pin),就(jiu)需要(yao)我們(men)(men)通過(guo)手動調(diao)(diao)節(jie)無(wu)線話(hua)筒(tong)(tong)(tong)或無(wu)話(hua)筒(tong)(tong)(tong)接收(shou)(shou)(shou)主(zhu)(zhu)機(ji)來(lai)實(shi)現二者的對(dui)頻(pin)(pin)(pin)。無(wu)線KTV話(hua)筒(tong)(tong)(tong)顯(xian)示屏顯(xian)示出來(lai)的頻(pin)(pin)(pin)率是多少,我們(men)(men)就(jiu)把無(wu)線KTV話(hua)筒(tong)(tong)(tong)接收(shou)(shou)(shou)主(zhu)(zhu)機(ji)面板上的頻(pin)(pin)(pin)率調(diao)(diao)節(jie)按鈕把其(qi)頻(pin)(pin)(pin)率調(diao)(diao)到多少,二者頻(pin)(pin)(pin)率一致后,無(wu)線KTV話(hua)筒(tong)(tong)(tong)接收(shou)(shou)(shou)主(zhu)(zhu)機(ji)就(jiu)可(ke)以接收(shou)(shou)(shou)無(wu)線話(hua)筒(tong)(tong)(tong)傳送過(guo)來(lai)的聲音信號了。
注意事項
1、無線KTV話(hua)(hua)筒的(de)(de)調(diao)頻(pin)是針對(dui)無線KTV話(hua)(hua)筒的(de)(de)接(jie)收(shou)主(zhu)機來說的(de)(de),在(zai)沒有(you)接(jie)收(shou)主(zhu)機頻(pin)率的(de)(de)情(qing)況(kuang)下,僅僅只對(dui)無線KTV話(hua)(hua)筒調(diao)頻(pin),是毫無意義的(de)(de);
2、如果覺得調無線KTV話(hua)筒接收主機(ji)不方(fang)便,也可以能過調節無線KTV話(hua)筒的頻率的方(fang)式,實現二(er)者的對頻。
二、無線ktv麥克風的種類
無線話筒(tong)按其使用的(de)制(zhi)式的(de)類型分為三種,分別是FM無(wu)線話筒、VHF無(wu)線話筒和UHF無(wu)線話筒。
FM 無線(xian)話筒,早期消費性(xing)無線(xian)話筒是利用(yong)(yong)FM收(shou)音機來接收(shou),系統簡單,成本低廉,但因使用(yong)(yong)效果,不能滿(man)足(zu)專業(ye)品(pin)質的(de)要求。
VHF無線話筒,又分為低(di)頻(pin)及高頻(pin)段(duan)兩類(lei)型(xing),使用(yong)天線長(chang)度太(tai)長(chang),又最容易受到(dao)各種電器雜波的干(gan)擾,因此這(zhe)一(yi)類(lei)型(xing)的產(chan)品,已經被高頻(pin)段(duan)所取代而(er)逐漸從市(shi)場上消(xiao)失 。
UHF無線(xian)話筒,使用頻率(lv)為300-3000M的無線(xian)話筒,是21世紀話筒應用的主(zhu)流,因為避免了V段的對講機等的干(gan)擾,所以(yi)穩定(ding)性(xing)有很(hen)大提高。
