This is why I have previously suggested that there is actually no analog gain control but that setting levels is always post ADC.
They say it quite clear. The maximum analog gain is 75 dB. And indeed, with the gain control set to "advanced" you have access to the
analog preamplifier gain.
If you apply gain with the fader then you are applying digital gain. And you can achieve a maximum of 96 dB from microphone to recording.
"The maximum analog gain is 75 dB. And indeed, with the gain control set to "advanced" you have access to the analog preamplifier gain"
From my reading this is largely correct, or at least its the impression I've gotten. This is why I sued advanced mode.
"If you apply gain with the fader then you are applying digital gain"
I think this is true in advanced mode but not in custom...
https://www.dvestore.com/blog/video-sound-devices-mixpre3-and-mixpre6-modes-and-signal-routing/"If you want discrete, isolated tracks, then you need to be in Advanced or Custom Mode. When you record ISO tracks, the tracks will record the audio signal that is post-gain but pre-fader to the isolated track. This is what we call pre-fader or pre-fade recording. However, you can have the ISO tracks be post-fader. You need to be in Custom Mode and enable advanced settings for both "Channel" and "Record."
This makes the ISO tracks post-fader. In Advanced Mode, the MixPres are configured...You also have separate control over the trim control which is the gain, as well as fader control.
The use of terms and the way something is said is important. In custom mode, the ISOs are post fader. Is this just a poor use of the term fader - and they really just mean big channel knobs used as fader controls in advanced mode - or does it mean it's a digital gain? Why say "post fader"?
I guess my conclusion that the pre-amp is a probably a digitally controlled, analog preamplifier. In other words, the knob are digital controls. In custom mode, the "fader" knobs also control the pre up to the maximum pre gain and then the purely digital gain kicks in?
