Q: 3. Any suggestions on the ideal phantom power source to use this mic with my Panasonic AG-HMC40P camera? Thank you.

Q: 4. Will this mic survive water being splashed on it?

A: Shure does not rate the MX395 Microflex Low-Profile Boundary Microphone models for water resistance. This will probably withstand one or two accidents or water spills, but I would not recommend installing it in an environment where that will happen frequently. If the microphone does get wet, it would be best to wipe it dry as soon as possible. Repeated exposure to spills or splashes will damage the microphone. For conference rooms where water spills are more likely, using a hanging mic like this suspended over the table could be less likely to suffer damage from accidents: https://bhpho.to/2xVQp7s

A: The abilities of the Shure MX391 Microflex Cardioid Boundary Microphone will likely be stretched when tasked with picking up voice from 6 to 8 feet, especially if some in this scenario are quiet speakers. For the best results in this specific situation, two MX391 would be ideal.
