Very noisy mic
Hi all,
Firstly, I must say that my knowledge of audio and microphones is very limited, but I'll try and explain this as well as I can. I have a Panasonic AG-HMC41E video recorder, with an AG-MYA30G XLR microphone adapter. I am using this with two microphones, one is a Rode NTG-2 shotgun, and the other is a Rode lavalier mic. When using the NTG-2, everything is perfect, but the lavalier mic has an unbelievably loud hiss. It's like listening to the waves on the beach (but constant). Is it possible this has something to do with the phantom power? When I switch the phantom power of the XLR input "off", the mic sounds perfect, with no hiss, for a few seconds until it dies out. Then I switch the phantom power back on, and the hiss starts up again. Can you have too much phantom power? I have tried different cables, and I get absolutely no hiss with the NTG-2 (either powered via the mic or the XLR input). I just don't know enough about microphones, and I was hoping someone might be able to make some suggestions. Thanks, Bruce |

Are you powering it via the Micon 48V XLR adapter?

Bruce, where did you get the Rode lav mic and how long have you had it. Did it all come in the one package?
Cheers

It's only a week old, and this its first use.
I've been on the phone to Rode, and they think it's a faulty mic. I'm glad it wasn't me! Thanks for your help. Bruce |

I've just been to see the guys at Rode, and they were extremely helpful.
Turns out it was a faulty Micon adapter. Bruce |
