产品描述 Product Description
●采用UHF超高频段,比传统的VHF频段干扰更少,操作距离范围更远。
●DDS直接数字频率合成技术,提供更多频道使用,提供2*100个频道选择,更容易多套机器同时使用,轻松避开干扰。
●全新数字导频技术,抗干扰性能更好。
●IR红外对频技术,只需要轻轻一按,发射机就和接收机的频率同步一致,使用方便。
●AUTO SCAN功能,自动搜索无干扰信道。
●发射器高低发射功率调整功能,节约电池电量。如学校教室,室内KTV包房可以使用低功率,节约电池使用时间更长。
●按键锁功能,防止误操作。
●液晶显示屏,使接收机和发射机的工作状态一目了然。
●UHF ultra-high frequency band is adopted, which has less interference than traditional VHF frequency band and has a longer operating distance range.
●DDS direct digital frequency synthesis technology, provide more channels to use, provide 2*100 channel selection, it is easier to use multiple sets of machines at the same time, easily avoid interference.
●Brand-new digital pilot technology, better anti-interference performance.
●IR infrared frequency matching technology, only need a light touch, the frequency of the transmitter and the receiver are synchronized and the same, easy to use.
●AUTO SCAN function, automatically search for interference-free channels.
●The transmitter's high and low transmitting power adjustment function saves battery power. Such as school classrooms, indoor KTV rooms can use low power, saving battery life for longer.
●key lock function prevents misoperation.
●LCD screen makes the working status of the receiver and transmitter clear at a glance.
