Juicedlink steps in

I still don't get it. If there is no loud sound, the signal sent to the DSLR will still be low, kicking AGC in. If the preamp raises the signal, it will be heard. What I am missing? Is it some 20+ kHz frequency that fools the AGC but cannot be heard by a human?
 
yeah, JL may be withholding exactly how they're disabling the AGC in that right channel. I mean, he says:

the DN101 automatically re-calibrates the meter for the appropriate signal levels (you will be cranking up the clean gain in the juicedLink preamp when AGC Disable is on, which throttles back the noisy amps in the camera).

I feel like JL is definitely trying to be as clear as possible, I just don't understand. But it sounds really good if you listen to the audio track.
 
It sounds to me like they're overloading the right channel to defeat the AGC, and leaving the left channel clean, so it turns your camera into a one-track recorder.
 
Yup, it's like Barry said. As always, the devil is in the details, and if you keep reading, they finally spill the beans.

The DN101 AGC Disable will take up one of the recording channels in the camera (right). When the AGC Disable is activated, the DN101 will headphone jack will only monitor the left input channel (through both ear-cups of the headphone). So, you will not hear anything in the headphones that is sent to the DN101 right input (as this channel will be used for the AGC defeat). This keys you to make sure that you have all of your mics panned left (the clean recording channel in the camera). For example, say you are using a CX431 with 4 mics. You will set the CX431 pan switches to 'left', and all 4 mics will be recorded by the camera on that track.

Which I find funny, considering they spend all that time talking about how injecting a tone into the recording is the wrong way to go about it. I think the hassle of having to delete the right track in post almost negates the convenience added by this.

My thinking, and I don't want to sound overly negative, but I think the next generation of cameras will -- at the very least -- have an obscure menu option to disable AGC. Rather than spending money on an AGC disabler, which is likely to become obsolete, I'd rather put that money towards a mic, a digital recorder, PluralEyes software...something that's likely to benefit me now, and in the future.
