The trim controls across the top will be different
The trim controls across the top of your T1 ToneMatch Audio Engine will likely be different. This is because the output levels of your input sources will likely be different. This is normal.
Mixing - Use the volume controls not the trim controls
Once you have set the input trim, you should not have to change it until you change the input source (e.g. different microphone, singer, or instrument). Do not use the trim control to change the channel volume. Use the channel volume control.
Scenes
Saved Scenes do not capture the trim, channel volume, or Master Volume settings.
