Some microphones, mostly condenser microphones have a thin plate/diaphragm in them that reacts better when warm then it does cold, They are powered microphones, and require a power supply to heat up the plate and diaphragm so that it sounds nicer.
They are designed for the purpose they are intended for. The KSM9 is VERY sensitive to stage wash, so the no brainer here is not using it on smaller stages, in front of a drum kit, and keeping the monitor envelope in the null. Doing that means less console work, and not doing that along with inadequate engineering is going to cause problems. I’ve found Heil handhelds do poorly on smaller stages, but unlike the KSM9 will they will tolerate wash better, which makes sense as they are dynamic units. Amazing product range for outdoor performances, especially the PR-37. Edit: I was attempting to reply to someone’s comment concerning the Shure mics in general/KSM9/etc. but tapped the general comment input box. I’ll just leave it here though lol.
Hi I had the kms7 and the kms9hc They were rubbish to me and feedbacked on every frequencie. I used them on a new digital Ulxd The said they were great, also on feedback but the opposit is true. I use Heil Rc35 capsules for year bit shure still cant beat the Heil, Hopefully the Shure Nexadyne NXN8/S can beat the Heil but i dont have must trust in shure anymore. They dont deliver what the promise
