I'd hope/assume 65-70% dcen.LOL, yeah, I know that now!
In my defence the unit was faulty and didn't work at all for various reasons so this picture could have been taken at any time. I experimented with all of the combinations and permutations of switches and knobs and intend to modify the front panel so it makes sense to me once I am happy with all the switches. It is an awesome machine though and flatters my lowly level of experience.
Incidentally, what actual level of balance do you suggest the 9 o'clock/position 3 actually is, based on that picture?
