Corresponding model of the radio transmission device approval certificate(CMIIT):
* Hand-held wireless transmitter T-52X
* Lapel, headset wireless transmitter T-52Y
Feature:
* UHF ultra-high frequency band dual true diversity reception, and PLL phase-locked loop multi-channel frequency synthesis technology.
* Provide options of 500 channels in total and 200 channels for each, true diversity reception, effectively avoid frequency interruption and extend the receiving distance.
* With SCAN automatic frequency scanning function, press the SET key before use to automatically find out the cleanest frequency point and keep it as the receiving frequency.
* The V/A screen is clear at any angle and displays the channel number and operating frequency at the same time, supports 8-level RF level display, 8-level audio level display, channel menu display, and muted display.
* Both balanced and unbalanced output ports are optional, meeting different equipment connection requirements.
* Super anti-interference ability can effectively suppress external noise interference and co-frequency interference.
* Infrared frequency matching function, which can synchronize the frequency of transmitter and receiver conveniently and quickly.
* Rich IF, magnetic and powerful sound, the essence of the vocal microphone. Touch button control is simple and user-friendly.
