The series adopts UHF(740-830MHz) and technology of DPLL.In 50MHz frequency bandwidth,with an interval of 250KHz,provide 200 channels selection,avoid all kinds of interference.
There is no interference under big power operation in same room,use 2 sets of 8 channels(that is 16 pieces microphone);if operate in low power situation in different room,quantity can be up to 100 pieces of microphone without interference in same building.
Rapid replacement channel module cards,work independently,convenient to maintain and save the cost.
The series wireless microphone selection:handheld,clip,head wearing,conference microphone,or any mix & match,flexible combination.
