Features
1. Uses the VHF220-270MHz segment, avoid the interference frequency. The high and intelligent degree of profession
2. Usage receives the electric cireuit, and block up to receive the dead cente.
3. Equipment can the connect 19 inch standard machine the accessories, connect the one side.
4. Adopts many elasses narrow take the high and inside cho0se the wave, cent the cancellation the interference signal.
5. Adoption specially presses to restrict electricity the road, need not anxious about volumes big but lose really.
6. Adopts the piece of low dollar, battery service life the special features.
7. Holds the invisible antenna, beauty of microphone practical.
8. Holds the microphone to have the low elcetric voltage the to instruction the electric circuits, and hint to replace the battery.
9. Establishes to hold the microphone switch the to pound at the wave to dissolve the electric circuit.
10. The quartz of all adoptions flap the electric circuit, and have the function of alpine frequency stability.
11. Adopts he to compress the to expand the technique and noise reduce, dynamic scope enlargement.
12. Establishes to have back to lose the to call press low die down the function, and can validate to let up back to lose the to cal special noise.
13. Function brush - off exterior the interference open the shabby system of this machine.
14. Make selections very good chip and high - quality zero parts, make this machine the quality extremely0utstanding.
15. It hasthe independence exportation to output with admixture, and can connect the modulation set with Karaoke enlarger.
16. It has the real equilibrium exportation, and can use the conjunction line of the long pull. But can not produce in the open and spacious and biggeer usage.
17. Distance 150 meter, open and spacious ideal usage distance 100 meter.
18. Be applicable to the size stage song and dance hall conventional center. The church lecture family amusement.
