^^^ second stage gain
Please elaborate, not sure I understand.
I use the mixpre-6 in advanced mode. I set recording levels by going to the gain menu for an individual channel and use the knob on the side to set the gain. This is setting the level of gain at the pre level (ie trim). I don't normally record the L/R mix, but the channel knobs control the gain going into the mix. This is a secondary gain (ie fader).
When you use custom mode (gain at simple), the trim level is set by the recorder and you are altering the second stage gain (or at least that's what appears to be the way it works) . It's not the end of the world, but I prefer to work with gain at the first stage.
The above is not totally correct. You have a choice on what you want the front knobs to do:
Gain Staging with Linking
In Custom setups, the Linking feature is found in Custom Setup > Channel >
Advanced, which lets you link inputs while still having the option of one or two
gain stages.
Users wanting to link inputs, but control all levels from the front-panel Channel
1 knob should set System > Mode to Custom and then in Custom Setup, set
Gain to Basic and Channel to Advanced.
Users wanting to link inputs with two gain stages while in Custom mode, ensure
that Gain and Channel are both set to Advanced. Then, you can adjust gain
levels for linked channels from the Channel 1 screen and adjust fader levels for
linked channels with the Channel 1 knob.
It's saying the exact same thing I am as far as I can see, in a slightly different way.
There are two gain stages, what I defined as trim and fader above.
Users wanting to link inputs with two gain stages while in Custom mode, ensure
that Gain and Channel are both set to Advanced. Then,
you can adjust gain
levels for linked channels
from the Channel 1 screen and adjust fader levels for
linked channels
with the Channel 1 knob.
Regardless of the linking aspect, this is what I do. I can set the trim (first stage) using the channel main menu item and the side knob and I could, if I cared about the mix, set the second level gain using the big knobs
but control all levels from the front-panel Channel
1 knob should set System > Mode to Custom and then in Custom Setup, set
Gain to Basic and Channel to Advanced.
This allows you to use the big knobs for controlling gain at the ISO level
but what you are controlling is the second stage gainThe custom (advanced/simple) route simply triggers ISOs to be recorded
post fader in addition tothe L/R track. They explain in their own video
