Special attention: If the shielding effect of this recording shielding system is not ideal for individual recording equipment, it is suggested to use two sets to solve this problem.

Ws-3 mainframe and expander shell adopt injection moulding technology, which is compact, beautiful and generous in appearance. The size of the mainframe is the same as that of the adult hand. The expander is 1/2 of that of the adult hand. It is light in weight and easy to carry.

Look at the parameter table in detail.

System characteristics:

1. The power can be adjusted. The stepless knob is used to adjust the power. It is precise and convenient.

2. Self-adaptive silencing technology ensures quietness in use.

3. The combination of host computer and expander forms shielding network, which has better shielding effect.

4. Adding on-board 12V adapter to meet in-car use

5. Shielding distance 1-2 meters

6. Over-voltage, over-current and over-heat protection

7. Important components are all imported electronic components.

8. Output effective power is over 98%.

9. Remote control switch, easy to operate and friendly

10. Injection Molded Shell, Green Environment Protection
