We are a sound engineering company and we have 8 line 6xd v55 receiver handhelds, bodypacks, lavalier and headsets and have frequently problems with dropouts. It might work for 4 hours without problems and than it starts with dropouts but it is always diffent. The audience (starting from 50 up to 2000) and venues are also diffrent all the time. Due to the facts of dropouts the line6 xd-v55 is not a option for a professional wireless microphon and we are curently selling them. Does anybody know if there are less dropouts with the v75 version?
