Noisy Canon C70?

[Kathy Smith]

I know C70 has a noisy preamp but I don't know if my C70 has faulty preamp or this is a normal noise level. Can someone verify for me? I'm attaching a file.

Some info:
1. Firmware 1.1.3.1
2. No mic attached
3. vol level set to 5, Manual
4. audio input selection set to INPUT TERMINALS Input1 MIC+48 for both channels.
5. No fan running while recording

Hi Kathy, I don’t have a Canon C70 but I set an average music level playback level on my latest iPad and listened to your noise sample. It sounded Ok to me, another example might be to have someone speak at normal level and record her/him at ‘normal’ level on your C70 and listen for the background noise on that example so you’ve got a reference. Is your firmware the latest version?

This might help you with your audio settings and check the comments …

And you should look around the web, there’s C70 groups. Don’t forget to let us what results you get, to help others here in future. Good luck.

Thanks Allan. I watched the video and I understand all the settings. I also reset camera to factory settings for testing purpose, but I get the same noise with factory settings. I'm on the latest firmware. The thing is I just feel like it's more noisy than it used to be. I just checked my files from 2 years ago and it's the same noise level, so maybe I'm imagining it. But I have no way of verifying my settings from 2 years ago and what my volume level was etc. The puzzling thing is that when I have no mics attached I wouldn't expect to have an audio recorded but when I drop my files to Final Cut, I do have a audio track and it's just noise. I can obviously delete it but I don't remember ever needing to do that. Maybe I need to find C70 forums and post there.
