Nice
I have never been a fan of AGC - so it's cool to see a workaround for video folks

How do they do it?  My guess is they output a high frequency tone (above 15k) that turns down the gain completely on the mic input.  Or I guess you could output something really low frequency as well.

Anyone else have a guess?

Hmm.  Maybe the ADC input of these recorders is OK.  Probably just as good as a NJB3 analog input, anyway.

Back to the AGC defeat mode. The DN101 beats Automatic Gain Control by injecting a strong signal into the right channel of the camera. The left channel is then used to record the clean "balanced" audio. This is why you can only hear the left channel through headphones in AGC defeat mode. To provide some sense of normalcy, the left channel is present in both the left and right ear cups. When setting up the preamp, make sure to set the Pan switches to the left position.

The AGC defeat method also has some implications on the editing of your project. Since the right channel is being blown out with a strong signal, you'll want to remove it from your timeline. Most non-linear editing software makes this easy to do. Just remember to do it. You want to edit with audio from the left channel only.
