This allows you to use the big knobs for controlling gain at the ISO level but what you are controlling is the second stage gain
The custom (advanced/simple) route simply triggers ISOs to be recorded post fader in addition tothe L/R track. They explain in their own video
Neither of the above is fully correct when you use the menu path of: In System > Set Mode to Custom and then in Custom Setup, set
Gain to Basic and Channel to Advanced. (As Noah also correctly states above) I checked with Sound Devices because I was sure I had full gain control and they clarified as such.
This is from my second email as the first one was really informative but not as crystal clear. (and to be brief that is because at the ISO setting above, the mix is also controlled, but if you do not use the mix it does not matter) Again to be clear the answer is for the path stated above.
Hello Clifford,
When linked, one fader will control gain for both inputs. Yes, this is full gain range from OFF to maximum gain.
Best regards,
Danny
I understand how to set the mixpre so you are controlling ISO gain with the big knobs!!! Everyone re-iterating this is not responding to my point. My point is more what is happening within the deck wehn you do this. There are very long threads about the Mixrpre-3/6/10 because there are many subtleties that have not been explained well. In some cases, we have been given conflicting information. If I am misunderstanding the mechanics of how the gain stages work, I am more than happy to hear a clear explanation.
https://www.youtube.com/watch?time_continue=36&v=vL_dmV8n43cThis is a video FROM Sound Devices and the implication is that my statement from above IS correctThe video explains how to use custom mode and then concludes "And there you have it, now
post fade signal, controlled specifically by the channel knob, is being sent to all your ISOs."
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 as either five or eight-channel recorders depending on which one you have. ... You also have separate control over the trim control which is the gain, as well as fader control."
I am assuming trim is one gain stage (one amplifier) and the fader is a second gain stage (another amplifier). Both of the above imply that the custom mode node thing is recording ISOs post fader. While I recognize they are both analog stages, my preference is to control gain at the first amplifier. That's all I have been implying since the beginning of my points. It was never a question of how to set the deck use Channel Knobs to Adjust ISO Levels.
So, are there two amplifiers? If gain under the custom scenario is post fader, what is happening at the trim level?
