We've just started setting up our first V70L with a Countryman e6i.  We don't see "green bars" all the time on the audio display which would be useful to know if there's audio on the channel without actually monitoring the channel.  Any suggestions?

We've walked the environmental filter through its settings (OFF, NORM, TALK) and wondered if there are details on the filter functions and/or response curves in the different options.

How does the Line6 headset mic compare with the e6i output and response wise?

Overall, no RF, range or response issues at all.
