·真正分集接收,宽带发射(50MHz),分段接收技术(两个独立的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。100间KTV包房不同频,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。
·1U金属机箱内建双频道接收电路,具有坚固、耐热及隔离谐波辐射干扰的专业品质。
·采用UHF/ PLL电路,纯自动选讯(True Diversity)接收方式,配合『音码及射频强度』静音控制,不但接收距离远,而且消除断音及接收不稳的缺失,防止点歌机、电脑及DVD光碟机等辐射杂讯的干扰。
·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
·True diversity receiver. 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.
·1U metal case have inner double channel receiving circuit. It has the professional quality of tightness, ovenproof and radiate disturb insulation.
·Use UHF/ PLL circuit, True Diversity receiving way,Together use with 『tone code and radio intension』mute control, avoid the radiate disturb from the song select machine, computer and DVD, it also have long receiving distance avoid break and unstable receiving.
·It has『ACT』auto channel lockup key, transmit auto lock the work channel of receiver once you press the SET key.
