KTV音響設備中無線話筒的調試要點:

1、在無專業無線電儀器的環境,不適宜調手持無線話筒(發射機),但可調無線話筒接收機,調整步逐如下:

2、打開無線話筒接收機的機蓋,將手持無線話筒上用低一點電壓的舊電池。

3、打開手持無線話筒和無線話筒接收機電源,把手持無線話筒放在胸口,背對無線話筒接收機,一邊呼喊一邊朝遠處行走,尋找一個盲音位置,把此位置定為盲音參照點。

4、關機,在無線話筒接收機的電路板上尋找到天線接入點,沿天線輸入電路,尋找到第一個可調電容、或者是可調電阻、或者是電感,(任選一種,優先第一器件),做好原位記號,逆時鐘或順時鐘方向微調一點。

5、開機,把手持無線話筒放在胸口,背對無線話筒接收機,一邊呼喊一邊走到盲音參照點,如果這個盲音區消失了,便是調整成功了。如逆時鐘微調一點,便改順時鐘方向微調一點,一、二次便能成功。
