Vinnfier WM1000U Professional UHF Wireless Microphone with Audio (1 yrs Limited Hardware Warranty) - VINN-WM1000U

We used to do experiments in the KTV room: to appropriately reduce the launch power of the handle (20-30 meter in use distance), using the "map four-color principle" method, each separated two-room.
can connect to multi-mic with different frequencies.

PERFORMANCE AND SPECIAL

If the receiver of the rain station should be set at a high distance( for example 10meter) the frequency alarm can be reused, such as if the receiver of the rain station only needs to separate the fixed distance. (for example, 10 meters)
with automatic static speech and shock elimination circuit, to avoid the middle stroke and noise of the gouging machine.
the handle has the function of LED digital tube display, and can directly pull the current display frequency.
wireless transmission effective distance 30-50 meter)
the battery circuit designed by hand has overcharge and over-discharge protection.
the simple operation interface and the few adjustable parts can completely avoid the malfunction caused by misoperation.
excellent speech quality, so that you can talk or song is loose and free.
The mic data is sent bt wireless to the receiver match the frequency. if the match is successful, the frequency can switch between 10 frequency. and the handheld can change the frequency at any time then the receiver will follow the handheld to adjust the frequency automatically and jump to the corresponding frequency.
provides the flexibility of frequency setting.
