1) DSP B won't feed analog 1&2 either.

2) Tried Monolithic preset 3057 "Super CH Strip 48k  II" and it did not pass signal. Checked the meters an had input on 1&2, Input to machine on 1&2, and not output from machine. Tried 4209 "4B X-over Hall II" with the same results. No meters flashing on machine output. I'm assuming I'm using the right methodology to trace the signal by checking the meters in this way to see where it disappears?

I ran both tests until p=10 and both E and T remained at 0 each time.
