Hagen Help! I get noise when plugging in GCX controller.

[slyvren]

When I plug my GCX into my Hagen I get a low pitched hum type noise. I can hear hum at all times and the hum changes when I use the controller. I can even 'hear' the display changing when it is in its boot up loop. As soon as I unplug the GCX no noise. Im powering via 7 pin phantom.

I do not have the issue with my vh4 using same cable and controller.

Any advice? Could it be a preamp tube? Hum Trimmer?


Thanks,
-John
