Lavs w/ HD100
I've discovered a problem recording with a Countryman B6 lav and the HD100. When I record the audio, even though the levels are peaking at -12, I get clipped audio. Not horrific, but noticable and I can see it in the audio wave in FCP (it flattens at peak even though it's in the proper range). I know this mic is very sensitive and with the PD150, I used the mic attenuator. There isn't a similar option with the HD100 (unless I'm missing it). I've tried -60db reference as well as -50db and it doesn't seem to make a difference.
Can anyone suggest a solution? Should I use an external attenuator? I love using this mic, but I'm afraid to with this camera. Is there some setting that I am not noticing? Does this belong in Now Hear This? If it does, I apologize. Thanks. |

I suspect the mic is clipping the signal.
Here's the data sheet on the B6. http://www.countryman.com/download/B...0datasheet.pdf Are you using a W4, 5 or 6? If you have a B6W4, make sure it isn't too close to the mouth. Are you using phantom power (MIC +48V.)?

Thanks for the response.
It's a gray band - the W5 which is supposed to be for lapels where I always put it. I don't think it's a placement problem or I would have encountered this with the PD150. I just checked the setting for phantom power and I have it set to Mic. Since the B6 doesn't have a battery, I guess I should have been using the +48 setting, no? It just now occurred to me that that is what the setting means. Could that have been my problem? Thanks. |

No, I'm going wired. I think it may be the phantom power thing. I can't believe I didn't check that before. How was I even getting audio without phantom power if my mic doesn't have a battery?
