Hello Mike,
I was pretty much tracking with you with your comments regarding the particulars on this SM7 although the last sentence of your post may have been scrambled. If I interpret it correctly, this thing' needs 137db to work properly? I knew that it needed a better than average mic pre, but dang!
That is 100 percent. It changed the percent sign to that %. On my x32 I have the gain all the way up and even did some additional digital gain in the console just so I have some headroom. Fortunately, the X32's Midas Heads are very quiet so I am not getting any noise at 100 percent.
Ahh Okay I see. That's a nice mixer you got there, so pretty much any mic pre/mixer of 60~66 is going to be maxed out in conjunction with a Fethead, Cloud etc., to keep the output smooth.
Well, that would deftly keep me from wanting to add this mic to my config. I already have a power-hungry RE20 but I don't think it needs quite that much juice.
I have an RE-20 as well, I do not have to do any digital gain with it and it is not at 100 percent but it is still much higher than most dynamic mics. I have been meaning to ask Mike Phillips if he knows why broadcast mics need so much gain vs other dyamics, even the Heil. My Heil mic's have more headroom than either the SM7B and the RE-20.
Interesting stuff for sure. It was my understanding that the PR40 was originally designed for Ham radio operators who are quite creative at running nuclear power plants out of their homes and shacks.

Reason: typo corrected
The fethead/cloud will boost your gain. So it would help with a dynamic mic for cleaner gain. It uses phantom power, but it does not pass phantom power through. Use a fethead and you won't have to turn your gain on your mixer so high.
Not bad. Mike Phillips in the past has said he does not like the Shure SM7B. I agreed with him until I heard Andrew with it. I guess it comes down to how its configured.
