The SQ consoles has a different mic preamp than the DLive. However if you use a DX or GX stagebox with the SQ, those stage boxes use the same mic preamp as the DLive. I cannot answer whether or not these is a big difference in the noise floor between the two different types however as I don’t have enough personal experience with the SQ console.
I will say that if you turn the “DLive” preamp up far enough, you will still hear floor noise through a set of headphones. However if I have to turn the pre up that loud during an actual event/show, it is usually because the gain staging is wrong on the input end of the signal chain – ie the output of whatever device I am plugging into the mic preamp is putting out too low of a signal. I suspect this is the case here too. Check your wireless mic settings and make sure it’s output is as high as possible and nothing is accidentally lowering the output of the device. Also as u/nottooloud suggested, make sure the mic preamp itself doesn’t have it’s pad engaged.
Please note that my experience is with the “normal” DLive mic preamps. I have not used the “Prime” Preamps but they are suppose to have lower noise floors than the regular DLive preamps.
