althemusicwizard Posted March 19, 2014 Share Posted March 19, 2014 Hi,I have 2 EW100 systems and 2 EW300 Systems. One of the EW100 systems has a problem that I think will have to go back to Sennheiser if I want it fixed. I just wanted to hear others thoughts before I contact Sennheiser.The receiver looks as if it's only receiving on CHI....CHII never illuminates when the mic / backpacks are moved around. I've changed aerials etc and backpacks / mics and I think eliminated other possibilities. has anyone ever had a unit do this before? I bought the units secondhand from a PA hire / AV company about 1.5 years ago and only really discovered the problem when I started using the fourth receiver more. It exhibits the problem as sudden drop-out as the receiver MUTES when it loses CHI signal. As I said, unlike the other receivers, CHII never illuminates. Any idea how much this would cost to sort out, as I might be better trying to buy just the receiver from Ebay and selling this one as part working / faulty.ThanksAl Link to comment Share on other sites More sharing options...
Ian Cunningham Posted March 19, 2014 Share Posted March 19, 2014 This looks like a fault in the diversity switching / sensing on the receiver Which generation of evolutions are they? The G1s had a known issue with the diversity switching which needed a new board fitted.Even when the parts were still available it wasn't really an economic repair. Another 2nd had receiver may be the best bet Ian Link to comment Share on other sites More sharing options...
althemusicwizard Posted March 19, 2014 Author Share Posted March 19, 2014 Thanks Ian.....I think they are the G1 series (the 9v battery for the transmitter packs). It's an expensive do this wireless malarky!. Al Link to comment Share on other sites More sharing options...
