DY-888 True Diversity Wireless Microphones
Applicable occasions: medium and large performance activities, stadiums, bars, conference halls, etc
- Details
The new True Diversity ultra long distance 300 meters without dead corners, with one click scanning of the cleanest frequency, simplifies installation and debugging difficulty. Digital pilot+ID code verification eliminates any signs of cross frequency interference. The working frequency module Hua does not need to be manually arranged, and the body is equipped with an integrated corner code
