Noise issue with HHLPRO UHF Wireless system

Hello,
I am using this wireless system:

to route output from this mixer:

to a Bose S1 Pro.

I am getting a LOT of noise. I have lowered the volume on both the transmitter and receiver, which helps slightly. Does anyone know of a good solution with this configuration?

Thanks!
