Sound cuts Me-1

Hello everyone,

I am currently on a show with a dlive and 5 ME-1 connected via a switch (not an A&H but one that works and has work 2 years fine)

4 of the ME-1 are working without any problem. One is doing a strange thing randomly and it has made it only 4 or 5 times on 20 shows.

The sound suddenly cuts and comes back after around 10 secs. The ME-1 stays ON and does not reboot. The firmware is the same on all. I tried to change the cable and the port on the switch but still does it.

Any ideas what could be the problem ? I will try a factory reset after the last show but it has never done this in 2 years on the same configuration.

Thank you !
