ER-3200一拖一分集无线接收机
    ER系列3200分集接收机采用分集接收无线电波方式，其稳定音质的分集接收方式，被广大用户肯定、认同。在接收机上装备两套天线输入电路，可以通过两支天线，同时麦克风信号，然后根据接收状态，自动比较、切换接收良好的信号。从而解决了断音、杂音干扰等令人烦恼的现象。
　　ER3100具有1/14英寸（TRS）和平衡卡侬（XLR）型两种输出方式的接插件，并有30dB的电平调节范围。XLR型输出端带有高/低电平开关，更有约60dB的控制范围。可以同任何电平匹配起来。精密设计加工的射频电路同压缩扩张电路结合起来，得以提供超卓的105dB信号噪声比（A线计权，108dB）。外接静噪（Squelch）控制使用户可以在调节接收机灵敏度，同时保持两个通道之间由工厂预校准的平衡。可分离的带接地交流电源线，将外部电网负同内部电源连接起来，使之可以在115V或235V的电网电压下工作，因此能适合世界各地使用。
