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.
