一、無線ktv麥克風如何調頻
調頻
1、無線(xian)話(hua)(hua)筒(tong)調(diao)頻(pin)(pin)可分為兩種(zhong)方式(shi),一(yi)種(zhong)是調(diao)節無線(xian)KTV話(hua)(hua)筒(tong)的(de)頻(pin)(pin)率(lv),另(ling)外一(yi)種(zhong)是調(diao)節無線(xian)KTV話(hua)(hua)筒(tong)接收主(zhu)機的(de)頻(pin)(pin)率(lv)。無論使用哪種(zhong)方式(shi),只要無線(xian)KTV話(hua)(hua)筒(tong)的(de)頻(pin)(pin)率(lv)和接收主(zhu)機的(de)頻(pin)(pin)率(lv)一(yi)致,就(jiu)可實(shi)現無線(xian)話(hua)(hua)筒(tong)正常工作。相(xiang)對(dui)來說,調(diao)節無線(xian)話(hua)(hua)筒(tong)接收主(zhu)機頻(pin)(pin)率(lv)的(de)方式(shi)比較簡(jian)單。
2、打開(kai)無線(xian)KTV話(hua)筒和接收主(zhu)(zhu)機(ji)的電源(yuan)開(kai)關(guan),無線(xian)KTV話(hua)筒與接收主(zhu)(zhu)機(ji)的顯(xian)示屏分別顯(xian)示當前各(ge)自的信道和頻率(lv)。正(zheng)常情(qing)況下,有些無線(xian)KTV話(hua)筒和接收主(zhu)(zhu)機(ji)的電源(yuan)開(kai)關(guan)打開(kai)后,無線(xian)KTV話(hua)筒接收主(zhu)(zhu)機(ji)通過紅外掃描自動對頻的功能,自動與無線(xian)KTV話(hua)筒當前的頻率(lv)和信道匹(pi)(pi)配,通過兩(liang)者的液晶顯(xian)示屏可看出(chu)是(shi)否已匹(pi)(pi)配。
如果無(wu)(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)(tong)與無(wu)(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)(tong)接收(shou)主機(ji)已自動(dong)(dong)對頻(pin),就不(bu)需要我(wo)們手動(dong)(dong)來(lai)調頻(pin)了(le)。若無(wu)(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)(tong)與無(wu)(wu)線(xian)話(hua)(hua)(hua)筒(tong)(tong)(tong)接收(shou)主機(ji)沒有自動(dong)(dong)對頻(pin),就需要我(wo)們通(tong)過手動(dong)(dong)調節無(wu)(wu)線(xian)話(hua)(hua)(hua)筒(tong)(tong)(tong)或無(wu)(wu)話(hua)(hua)(hua)筒(tong)(tong)(tong)接收(shou)主機(ji)來(lai)實現二者的(de)對頻(pin)。無(wu)(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)(tong)顯(xian)示(shi)屏顯(xian)示(shi)出(chu)來(lai)的(de)頻(pin)率(lv)(lv)是(shi)多(duo)少,我(wo)們就把(ba)無(wu)(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)(tong)接收(shou)主機(ji)面板上(shang)的(de)頻(pin)率(lv)(lv)調節按(an)鈕把(ba)其頻(pin)率(lv)(lv)調到多(duo)少,二者頻(pin)率(lv)(lv)一致后,無(wu)(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)(tong)接收(shou)主機(ji)就可以(yi)接收(shou)無(wu)(wu)線(xian)話(hua)(hua)(hua)筒(tong)(tong)(tong)傳送過來(lai)的(de)聲音信號了(le)。
注意事項
1、無(wu)線(xian)KTV話(hua)(hua)筒的(de)調(diao)頻(pin)是(shi)針(zhen)對(dui)無(wu)線(xian)KTV話(hua)(hua)筒的(de)接收主機來說的(de),在(zai)沒有接收主機頻(pin)率的(de)情況下,僅僅只(zhi)對(dui)無(wu)線(xian)KTV話(hua)(hua)筒調(diao)頻(pin),是(shi)毫無(wu)意義的(de);
2、如(ru)果覺得(de)調無(wu)線(xian)KTV話筒接收主機不方(fang)便,也可以能過調節無(wu)線(xian)KTV話筒的頻率的方(fang)式,實現二者的對(dui)頻。
二、無線ktv麥克風的種類
無線話筒按其使用的(de)制式的(de)類型(xing)分(fen)為三(san)種(zhong),分(fen)別(bie)是FM無線話筒(tong)(tong)、VHF無線話筒(tong)(tong)和UHF無線話筒(tong)(tong)。
FM 無線(xian)話筒,早期(qi)消費(fei)性無線(xian)話筒是利用FM收音機來接收,系統簡單,成(cheng)本低廉,但因使(shi)用效果(guo),不能滿足專業品(pin)質(zhi)的要求。
VHF無線話筒,又分為低(di)頻(pin)及高(gao)頻(pin)段(duan)兩(liang)類型,使用天線長度太長,又最容易(yi)受到各種電器(qi)雜波的干(gan)擾,因此這一類型的產品,已經(jing)被高(gao)頻(pin)段(duan)所取(qu)代而逐漸從市場上消(xiao)失 。
UHF無線(xian)話筒,使用頻(pin)率為300-3000M的(de)無線(xian)話筒,是(shi)21世紀話筒應用的(de)主流,因(yin)為避免(mian)了(le)V段的(de)對講機等(deng)的(de)干擾(rao),所以穩定性有很大提高(gao)。
