it is possible that the OP needs to adjust the Mic offset.  If the Transmitter is getting the clip. 

Matching Audio Levels with Mic Offset
When linking two transmitters to a receiver, there may be a difference in volume levels between microphones or instruments.
If this occurs, use the MicOffset function to match the audio levels and eliminate audible volume differences between
transmitters. If using a single transmitter, set MicOffset to 0 dB.
1. Turn on the first transmitter and perform a sound check to test the audio level. Turn off the transmitter when finished.
2. Turn on the second transmitter and perform a sound check to test the audio level.
3. If there is an audible difference in the sound level between the transmitters, navigate to the MicOffset menu on the
transmitter to increase or decrease the Mic Offset in realtime to match the audio levels.

Mic offset is for just what is described in those instructions, to match 2 differing transmitters to a single receiver. It is not for adjusting the transmission level. Overload in the transmission is handled automatically by transmitting both a high level and a low level signal and having the receiver switch to the appropriate stream.

I am seeing the clipping on the mixer but thank you for this information.  It helps me understand what the Mic Offset is for.

That was simply a copy-n-paste from the manual. Hopefully you still have that floating around... :)

And re your mention of Hi vs Lo RF power- that's just for the transmission power, not the actual signal sensitivity. We typically keep ours on low, unless we're working outdoors or in a large space where there's a need for longer distances between the transmitter and the receiver. (Or, if you get interference from an outside source, boost the transmit power to keep your signal the priority at the receiver.)
