Feature

1, Using UHF676 to 1697MH band channel ，A: 677-686MHz: Channel B; 687,696MH2O, strong disturbance resistance.

2，dopt 24Bit148KHz's high performance audio dedicated AD and D / A theory.

3，Use D leaf whisker rate to encrypt frequency and use phase frequency. When receiving chip is interfered with RF.,

4，If the receiver of the rain station should be set at a high distance (for example, 10 meters), 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).

5， with automatic static speech and shock elimination circuit, to avoid the middle stroke and noise of the gouge machine. 

6，The handle has the function of LED digital tube display, and can directly pull the current display frequency.

7， Invalid loss distance 50-60 meters. 

8. the battery circuit designed by hand has overcharge and over-discharge protection.

9.The simple operation interface and the few adjustable parts can completely avoid the malfunction caused by misoperation.,

10，Sagittarius taste has a low electroplating function. When the battery diagram drops to 2.2 V, the battery marks flash height of the pick up sensitivity, 

11，excellent speech quality, so that you talk or song are loose and free. 

12. Can be used simultaneously without multiple stations. No interference and frequency alarm. 

13. Indication of power supply and non-fouling indicator.
