What if I'm plugging in a lapel mic's receiver box to one XLR input of an AudioBox and a condenser mic to the other input with 48v turned on? Is that still safe or will it damage the wireless receiver system for the lavalier mic?

It depends on the receiver. Some of them are fine with it, others aren’t. I imagine that cheaper one’s could lose an output stage if you do that. Should be in the manual or you can email the manufacturer. 

I don’t recall off the top of my head if the ubiquitous Shure, Samson, or Sennheiser protects against this. All Lectrosonics receivers in the last 15 years or so, for example, are A-OK with this.,714/tag,Wireless,%2048,%20phantom%20power,%20damage,%20receiver/view,faq/

For others who are reading, you should be able to go line out (using a 1/4" instrument cable) from the wireless receiver instead of XLR into the audiobox to bypass the 48v.
