Amplifier Speaker Microphone Earphone Equipment Consumables
PMX300U wireless microphone
One drag two U segment wireless infrared counterfrequency wireless microphone, 200 frequency channels (100 left and 100 right optional). The function of sensitivity adjustment can be used when speaking microphone and conference microphone are used in speech and temporary meeting. Since it is a moving microphone, the effect of use is not less than or exceed the effect of speech and conference microphone.

本机特点:
一拖二U段无线红外对频无线麦克风,200个频率通道(左右各100个可选 )。
锁屏功能操作:
关机后按住左边UP键开机,显示屏锁死,除开机键外,所有按键无法调节,解锁重复操作,解除锁屏,所有按键可操作。
拾音高灵敏操作:
手持话筒开机按住开机按键不放手,进放灵敏度调节界面。1.2.3.4.5可调,数字越大灵敏度越高,按键按一次变一个数字,调到所选数字后放手显示屏闪烁几下后保存,就可正常使用,调节时离音箱远点,以免啸叫,正常调到3-4左右灵敏度也足够使用,拾音距离可达50CM左右,为了不让用户调乱后无法调回。手持一旦关机后再开机恢复到出厂设置,用户所调灵敏灵关机后不再保存。调灵敏度功能可在演讲,临时开会时当演讲麦克风,会议麦克风使用,由于是动圈麦克风,使用效果不低于或超越了演讲,会议麦克风的效果
