使用方法
█
用配置的Mini XLR音频线将麦克风连接到录播系统、远程会议系统、功放、调音台
等音频设备上，如下图所示：

C.使用48V幻象供电器与麦克风的连接示意图：
B.使用带48V幻象供电的调音台与麦克风的连接示意图：
A.使用带12V幻象供电的录播系统或远程会议系统与麦克风的连接示意图：
提示：使用时，应先将音频设备的音量调小，再打开幻象电源开关，并将音量从小
到大慢慢调节至合适，以免声压过大对扬声器产生冲击；尽可能的拉开麦克风与扬
声器的距离，避免麦克风和扬声器相对，从而有效控制回馈啸叫。
一、麦克风没有声音
1．检查麦克风所连接的音频设备是否有提供9-52V幻象电源的功能，没有幻象供电
麦克风不能工作；
2．检查所连的音频设备麦克风音量是否调得过小，调节之后看是否能恢复正常；
3．检查所连的音频设备总输出音量是否调得过小，调节之后看是否能恢复正常。
二、连接音箱时产生啸叫
1．如果使用的音频设备本身有回音消除功能，请设置为开启状态；
2．将麦克风的拾音部分背对音箱，同时保持适当的距离；
3．减小麦克风音量或音箱输出音量。
