Out of the blue one of my 414`s has lost its recording level. I'm using a pair for drum OH`s I checked the pads, phantom power and everything seems to be adjusted as it should be. I even changed cables and tried different channels but, no difference. so i'm pretty sure it`s the mic. because I have to crank up the pre amp gain much higher on the problem mic to get the same recording level as the other. this has never happened before! did I blow the capsule?......anybody have any comments?
