Confirmation of Limiter Circuit Only

I can confirm that the mic-in on my JVC HD7 has a limiter function only and not auto gain. I tested with both a Shure SM-57 dynamic mic and a Rode NT3 condenser mic. Running a 1 khz tone from my computer to an external speaker, I was able to record with both microphones. There are 9 green bars for each channel and 2 red bars (virtually impossible to count without my best reading glasses). My camera gave me a repeatable -11db to -12db when the JVC displayed 6-7 green bars per channel. Allowing the bars to ride into the red, even briefly, overloaded the input when using the NT3. I measured this in Soundtrack pro and Final Cut Express HD.

Thanks for all the useful information. Personally, I think this is preferable to having auto gain. I record most of my audio using a separate Sony PCM D50, but I may try some more audio direct with a Beachtek or alternative.

Mr. Mullen, would you please include me on your list to receive your latest updates. I've sent an email a few weeks ago, but it may not have gotten thru.

Thanks,

Ben Patrick
