产品介绍
UR-710S(多频道真分集接收机)
UR-700H(手持式麦克风)
UR-700T(腰包式领夹咪)
UR-710S 系统是一款适合专业舞台演唱用的无线麦克风系统，采用众多领先业内的高新技术设计于一身：超高频段（UHF）传输、真正分集式接收、双CPU控制、液晶显示、PLL锁相环技术、杂讯检测等，具有300个频点可调、易于操作的优点。
采用微电脑CPU控制：系统整个硬件电路由微电脑进行控制，可以进行选频、显示、静音锁定、电池容量监测等处理，实现传统机型不易实现的各种功能。
液晶显示：采用高性能的液晶进行显示，所有的控制菜单均可以在液晶屏进行显示，便于对系统进行控制。可以显示的内容包括：频率、群组、人名、静音电平、射频信号电平、音频电平、低电警告等。
