Saramonic UwMIC9 Volume Issue

[Hayk]

Hi i am using Saramonic UwMIC9 96-channel digital UHF wireless  microphone system, which includes 2x TX9 bodypack transmitter and RX9 portable receiver.

Problem is that both of my RX9 receivers record volume in a different level during video interviews when i record 2 people at the same time and my wish is to equalize both receivers recording level at the same height.
I even make myself tests when i read same text with both receivers but receiver with Group B at 556.510Mhz was low and Group A with 514.560Mhz was much higher. I have checked all the settings on the receivers and they are the same, but i don't understand why during recording interviews of people both receivers record volume in a different level. Any advice will be helpful, thanks.

Because they're Saramonic? That's my first and second guess as to why. 

Still, if that's your worst complaint, that at least means they're doing a million miles better than their total screw up that was their initial release of the UWMIC9
