Features

Functional Features:
Intelligent Management |
The optional “RWW” wireless transmission system monitoring and management software can use computer networking to monitor on-site, search for radio wave interference points in the actual environment of the scene and frequency blind spots on the stage, and control and modify system settings. |
|---|---|
Energy Conservation |
Precise low consumption circuit design makes the battery life twice as long as that of ordinary microphones. |
IR Infrared |
With [IR] infrared automatic frequency matching function, as long as the [SYNC] button is pressed, the transmitter can automatically and accurately lock the working frequency of the receiver. |
Super Wide Frequency Range |
32MHz broadband design, more than 1280 frequency points can be selected, true diversity reception |
AFS(Automatic Frequency Selection) |
With [AFS] automatic search channel function, after pressing the [AFS] key for 3 seconds, it will automatically search and lock on an undisturbed working channel. |
Anti-Interference |
The stable PLL phase-locked oscillation circuit, combined with the “noise detection” mute control function, can effectively block the noise and radio frequency interference in the working environment. |
