Silverhead gives some great advice and highlights one of the only issues I have with the M20d and that is that the Trim Level (otherwise known as Gain on some desks) is not at the forefront of the Setup page and I think it's easy to forget that it's even there, till you have issues that is.

Just remember whether you are recording or playing live, you need to Trim all your input channels first so that you ideally get the trim meter to hit 0 to ensure you have a good clear signal running through the desk.

It's exactly the same process you would go through for trimming a regular mixing desk, there is just a slightly different process on the M20d.

I am guessing Line 6 figure people will use the Auto Trim feature provided and therefore won't have as much need to use the Trim encoder but I wonder if there is a possible way of bringing the Trim feature to the forefront for users who either don't want to, or don't have the option to use auto trim and need to access the trim encoder much faster on each channel when line checking the desk.....

In an ideal word for me personally, the trim encoder would appear as default on the setup page, and then I would switch to Peform mode for setting channel levels......

Unless of course there is already a way to make the Trim Encoder the default on Setup?

The auto trim dialog shows the channels selected for auto trimming in red. The trim result for each channel is the same, about +5dB. Once the auto trim is done and you press "confirm changes" the trim does not change.
