(6) 电源插座：连接12V DC 电源至输入插座；插座的中心电极连接正电压。（注意：
必须使用标配电源适配器。)
(7) 天线连接座：连接外置天线，增加使用距离。接收机采用1/4波长天线。操作时，
使天线与主机成90度角，且天线离墙体（特别是金属体）应有0.5m距
离。(注意：接收范围和很多因素相关，若在传输方向无大型金属件阻挡，
可获得更好的传输效果。)

)音频平衡输出：采用“XLR”型插座，两通道信号分别输出；接收机输出与下一级
需要连接的音频设备距离较远时，建议使用此输出端口，以消除外界
噪声干扰。
(9)音频非平衡输出：采用“P”型插座，两通道混合信号总输出。

(3) 红外对频窗口：配合SET键，将频道参数传至发射器。在未开发射器的情况下，应观
察辅助栏显示的RF和AF指示，若有强的干扰，应调换频道避开干扰
点。打开发射器电源后，对应频道的RF指示灯亮，将接收机音量调整
到适当的大小，然后对麦克风发音，接收机AF指示灯对应麦克风音量
大小点亮。如果没有声音输出和指示灯不亮，表示此系统工作不正常，
必须检修。
(4) 电源开关键：长按此键3秒开启关闭机内的电源供电；电源开关打开时，LED显示屏
亮。
(5) 功能按键：用于频率调整、对频、按键锁定等操作。按中间键 "SET" 选择菜单及设置
确认：按
键对当前频道进行调整，再按 "SET" 键设置就可生效；
长按 " " " " 键可快速步进选择频道；直接按 "SET" 键，接收机进行红
外对频信号的发送。长按 "SET" 键进行按键锁定和解锁操作。
