无线接收机主要特征
·宽带发射(50MHz),分段接收技术(两各独立的25MHz子频带):接收机左右两个通道具有独立的100个频道可调,宽带发射器又可通用于左右两个子宽带,特别适合大量同时使用的场所。彻底解决串频问题。100KTV包间不同频,即使超过100间的场所,通过不同空间使用同频的复用亦可轻松应对。
·具有『ACT』自动频道追锁按键,只要一按SET键,就能立即使发射器自动精确锁定接收机的工作频道,绝不产生错误及故障。

Characteristic
·Wideband transmit(50MHz), subsection receiving technology ( two separate 25MHz sub-bands):The receiver has total 100 adjustable frequencies in L/R channels. Wideband transmit also can use in L/R sub-bands, totally resolve the frequency babble problem, special suit to use in the big quantity perform. 100KTV have difference frequency, even use over in 100KTV,it can also operate in use the same frequency but difference space.
·It has『ACT』auto channel lockup key, transmit auto lock the work channel of receiver once you press the SET key.
