K8400 One for four wireless microphone
Strong anti-interference. PLL phase-locked loop and high-precision quartz crystal, coupled with microcomputer microcontroller control, the frequency stability is extremely high.
Equipped with infrared frequency (synchronization) function, which improves the convenience of using the product.
With advanced digital pilot function, it completely eliminates interference and channeling. With three-way and logical relationship of automatic mute and shock elimination circuit to avoid the impact and noise of the switch.
With automatic signal selection function, it can quickly and accurately find the available channels without interference, which greatly simplifies the debugging work in the engineering installation.
With adjustable transmission power and adjustable noise threshold, the combination of the two can effectively and conveniently control the distance of use. Adopt double booster circuit design, the battery voltage will not affect the emission
