Strange issue with my Lekato wireless system.

Ive bene using a set of Lekato WS90’s for a while now. single is clear and ive never had any dropouts.

A week or so ago i brought an Ampeg SGT-DI. I noticed that when the preamp was not engaged, but the IR was on, i was getting a lot of horrible noise. This was when using the WS90. My Xvive and cables were fine with it. I send it back. 

This week i got a EBS Microbass 3, and although i have no issues with it, i get a loud hum if i put my hand near, or worse, on, the WS90 when its off but plugged in to the EBS. When the WS90 is on it’s fine. It’s like when you have a cable thats not attached to anything at the other end. Cant figure out why this happens when it’s off and im close to it. 

Poor shielding is the only thing that comes to mind.
