The HS I volunteer at use 14 Shure ULX wireless with both handheld and body pack transmitters. My question is, would you ever lower the output level from the wireless receivers to get a high gain setting on the mixing board. Many of the gain settings are at about the 9 - 10 o'clock position. I've been in a debate with a parent with "some" audio experience that keeps claiming I need to lower the outputs so my gains at unity fader level is roughly at the 12 o'clock position. I've never heard of this and haven't found anywhere in my research that this is an acceptable setup. Any information would be greatly appreciated.
