一、無線ktv麥克風如何調頻
調頻
1、無(wu)線(xian)話(hua)(hua)(hua)筒(tong)(tong)調(diao)(diao)(diao)頻(pin)(pin)可(ke)分(fen)為兩種(zhong)(zhong)方(fang)式(shi),一種(zhong)(zhong)是(shi)調(diao)(diao)(diao)節無(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)的頻(pin)(pin)率(lv),另外(wai)一種(zhong)(zhong)是(shi)調(diao)(diao)(diao)節無(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)接收(shou)主機(ji)的頻(pin)(pin)率(lv)。無(wu)論(lun)使用哪種(zhong)(zhong)方(fang)式(shi),只(zhi)要無(wu)線(xian)KTV話(hua)(hua)(hua)筒(tong)(tong)的頻(pin)(pin)率(lv)和接收(shou)主機(ji)的頻(pin)(pin)率(lv)一致,就可(ke)實現無(wu)線(xian)話(hua)(hua)(hua)筒(tong)(tong)正常工作。相對來說,調(diao)(diao)(diao)節無(wu)線(xian)話(hua)(hua)(hua)筒(tong)(tong)接收(shou)主機(ji)頻(pin)(pin)率(lv)的方(fang)式(shi)比較簡(jian)單。
2、打開無(wu)(wu)線(xian)(xian)KTV話(hua)(hua)(hua)筒和(he)接(jie)(jie)(jie)收主機(ji)的電(dian)源開關(guan),無(wu)(wu)線(xian)(xian)KTV話(hua)(hua)(hua)筒與(yu)接(jie)(jie)(jie)收主機(ji)的顯(xian)示(shi)屏分別顯(xian)示(shi)當前各自(zi)的信(xin)道和(he)頻(pin)率。正常情況下(xia),有(you)些無(wu)(wu)線(xian)(xian)KTV話(hua)(hua)(hua)筒和(he)接(jie)(jie)(jie)收主機(ji)的電(dian)源開關(guan)打開后,無(wu)(wu)線(xian)(xian)KTV話(hua)(hua)(hua)筒接(jie)(jie)(jie)收主機(ji)通過紅外掃描自(zi)動對頻(pin)的功能,自(zi)動與(yu)無(wu)(wu)線(xian)(xian)KTV話(hua)(hua)(hua)筒當前的頻(pin)率和(he)信(xin)道匹(pi)配,通過兩者的液晶顯(xian)示(shi)屏可看出是否已匹(pi)配。
如果無(wu)(wu)線KTV話(hua)(hua)筒(tong)與(yu)無(wu)(wu)線KTV話(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)(ji)已自動對(dui)頻(pin),就(jiu)不需要我們手動來(lai)(lai)調(diao)頻(pin)了。若無(wu)(wu)線KTV話(hua)(hua)筒(tong)與(yu)無(wu)(wu)線話(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)(ji)沒有自動對(dui)頻(pin),就(jiu)需要我們通過手動調(diao)節無(wu)(wu)線話(hua)(hua)筒(tong)或無(wu)(wu)話(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)(ji)來(lai)(lai)實(shi)現二者的(de)(de)對(dui)頻(pin)。無(wu)(wu)線KTV話(hua)(hua)筒(tong)顯示屏顯示出來(lai)(lai)的(de)(de)頻(pin)率是多少,我們就(jiu)把(ba)(ba)無(wu)(wu)線KTV話(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)(ji)面板(ban)上(shang)的(de)(de)頻(pin)率調(diao)節按鈕把(ba)(ba)其頻(pin)率調(diao)到多少,二者頻(pin)率一致后,無(wu)(wu)線KTV話(hua)(hua)筒(tong)接(jie)收(shou)主(zhu)機(ji)(ji)就(jiu)可以接(jie)收(shou)無(wu)(wu)線話(hua)(hua)筒(tong)傳(chuan)送過來(lai)(lai)的(de)(de)聲(sheng)音信號了。
注意事項
1、無(wu)(wu)線KTV話(hua)筒的調頻是針對(dui)(dui)無(wu)(wu)線KTV話(hua)筒的接(jie)(jie)收主機來說的,在沒有接(jie)(jie)收主機頻率的情況(kuang)下(xia),僅(jin)僅(jin)只對(dui)(dui)無(wu)(wu)線KTV話(hua)筒調頻,是毫無(wu)(wu)意義的;
2、如果(guo)覺得(de)調(diao)無線KTV話筒接(jie)收主機(ji)不方(fang)(fang)便,也可以(yi)能過調(diao)節(jie)無線KTV話筒的(de)(de)頻率(lv)的(de)(de)方(fang)(fang)式,實現二者的(de)(de)對頻。
二、無線ktv麥克風的種類
無線(xian)話(hua)筒按其使用的(de)制式的(de)類(lei)型分為三種,分別是FM無線話筒(tong)、VHF無線話筒(tong)和(he)UHF無線話筒(tong)。
FM 無線(xian)話筒,早期(qi)消(xiao)費(fei)性無線(xian)話筒是利用FM收音(yin)機來接(jie)收,系統簡單,成本低廉,但因使用效果,不能(neng)滿(man)足專業品質的要求。
VHF無線(xian)話筒,又分(fen)為低(di)頻(pin)及高頻(pin)段兩(liang)類型(xing),使用天線(xian)長度太(tai)長,又最(zui)容易受到(dao)各種電(dian)器雜波的干擾,因此這一類型(xing)的產品(pin),已經(jing)被高頻(pin)段所取代而逐漸從市場上消失 。
UHF無線(xian)話筒(tong),使(shi)用頻率(lv)為300-3000M的(de)無線(xian)話筒(tong),是21世紀話筒(tong)應用的(de)主流,因為避免了V段(duan)的(de)對講(jiang)機等的(de)干擾,所以穩定性有很大(da)提(ti)高。
