I currently use my mics through an Sp-sb-11 battery box into an editol r-09, and I record rock shows stealthy, they could be in arenas, theatres, basically all kinds if venues. I asked SP if i bought cmc-8 mics would they need the low sensitivity mod applying to them, their answer was yes if it will be ear bleeding loud, but no if they won't be that loud. As a guide they said that approx 1 in 50 have the mod done.
My question to those with experience of these mics is this, is the low sensitivity mod necessary?
