Ch 2 works fine, with about one small division of excess available using both

I think that's not enough, meaning that overall gain for *both* channels isn't enough. Usually, there's at least half a major division headroom.
Did you try the other vertical slot of the mainframe?
Do you know the mainframe is ok? Do you have another plugin to check the mainframe?

If the mainframe is new to you, a previous owner may have adjusted mainframe vertical sensitivity incorrectly.
